Some of the most popular developer tools, frameworks and experiences in the world are built around open communities.

Here are a few featured Microsoft projects of note. Accessibility Insights is a suite of open source tools that help developers find and fix accessibility issues in Web, Windows and Android applications. We are building value together and welcome everyone to participate. Together, in the open, it's an exciting time to use technology to build hacks, apps, and services.

We have worked to develop a strong open source program over the past decade, making it easy for every team at Microsoft to choose to use, contribute to, and release open source software. Many of our tools and approaches are available for you to learn from, too. Trust is key to open source. Developers should be able to trust users to respect their licensing choices.

And when you receive software, you should be able to trust that the open source licenses were followed. We welcome you to our open communities. However, the OpenAL does not support culling a source from processing based on a distance threshold.

At this time OpenAL is not meant to support culling at all. Culling based on distance, or bounding volumes, or other criteria, is best left to the application. For example, the application might employ sophisticated techniques to determine whether sources are audible that are beyond the scope of OpenAL.

In particular, rule based culling inevitably introduces acoustic artifacts. Description This module corresponds to section 3. Constructors NoAttenuation Bypass all distance attenuation calculation for all sources. InverseDistanceClamped Inverse Distance clamped model, which is essentially the inverse distance rolloff model, extended to guarantee that for distances below referenceDistance , gain is clamped.

LinearDistance Linear distance rolloff model, modeling a linear dropoff in gain as distance increases between the source and listener.

ExponentDistance Exponential distance rolloff model, modeling an exponential dropoff in gain as distance increases between the source and listener.

The order in which various gain related operations are applied is: Distance attenuation is calculated first, including minimum referenceDistance and maximum maxDistance thresholds. The result is then multiplied by source gain.

If the source is directional the inner cone angle is less than the outer cone angle, see coneAngles , an angle-dependent attenuation is calculated depending on coneOuterGain , and multiplied with the distance-dependent attenuation.

The resulting attenuation factor for the given angle and distance between listener and source is multiplied with sourceGain. The effective gain computed this way is compared against gainBounds. The result is guaranteed to be clamped to gainBounds , and subsequently multiplied by listener gain which serves as an overall volume control.

Apart from learning about the concept of the program host Open AL, for the people who have not yet installed OpenAL software before, you may now consider downloading it on Windows 10 so as to make full use of its cross-platform 3D audio effect. That is fantastic in games and audio devices. There is another way to download and update Open AL easily and fast. You can use Driver Booster to help you.

Download , install and Run Driver Booster on Windows Click Scan. Driver Booster will scan your computer to find if there is an OpenAL or if it is outdated. Now you can obviously see Open AL program is downloaded and installed.

You may as well attempt to run it in games or audio software. If you noticed that your OpenAL cannot function as well as before, maybe it indicates that you should get a new Open AL driver for this software 3D audio. You can get it simply online. With the help of it, your Open AL is able to provide 3D headphone surround service for you. In some games, the Rapture3D is included automatically and for other games, you need to modify the config file so as to activate this Rapture3D player in OpenAL.

Hope the updated Rapture3D Open al driver is capable of bringing you the high performance of games. Fix the unsecapp. How to Share Games on Steam Windows

Universal Conquest Wiki. But Coffman is the person who finishes the thousand-page Holocaust novel. Whatever she chooses to spend her time on—powerlifting, fragrance collecting, denazification—she approaches the assignment like a straight-A student. You can time-travel back and watch her begin. Wikipedia never forgets; it keeps a permanent public record of every change an editor makes. In early November , you will find K. A sentence has jumped out at her. And to her it seems strangely flattering.

Coffman navigates over to the Wikipedia article about one of the conspirators—Arthur Nebe, a high-ranking member of the SS. The article acknowledges both of these facts, along with the detail that Nebe tested his system on the mentally ill. She checks the footnotes.

The claim is attributed to War of Extermination , a compendium of academic essays originally published in Coffman knows the book is legit, because she happens to have a copy on loan from the library.

The level of bad faith is eye-opening for Coffman. She begins to turn a more critical eye to what she sees on Wikipedia. Especially the footnotes. In a long spree of edits, Coffman cleans up the two articles. She copy-pastes the language about the grand, futile gesture.

With a click, the paragraph is gone. She identifies two more dubious sources—one misleadingly quoted, one potentially invented. Truth, factual and moral, hangs in the balance.

Similar battles over how to remember the past have been raging across society. Do we let the old bronze statues stand in our boulevards, or do we put them in a museum someplace, or do we melt them down? Are qualities like valor and self-sacrifice and tactical brilliance worth admiring anywhere they occur, even if, say, racial supremacism is there too?

Some choose to take to the streets. Coffman fights on the terrain most familiar to her, with the weapons she knows best.

One Saturday night she updates it for the first time. Coffman was raised by engineers in the waning days of the Soviet Union. She went to galleries, museums, the theater.

No one wants to be in the 5th minute of a WOD snatching their brains out and thinking about a tri-blend aggressively massaging them into asphyxiation. Make sure you have a towel to clean up after yourself, and if you sweat profusely, make sure you have at least two towels or a beach-sized towel.

Wear deodorant. Be respectful and have situational awareness. Those guys ruin the training vibe and waste space that others are trying to use. Taking your shirt off in public can be a pretty frightening thing. We tend to be worried about what other people think. That's the type of gift that doesn't get regular STD tests.

Of course, it's not always so black and white. There are times to expose yourself to the elements in the name of comfort, convenience, or performance. And in , when, if you can dream it as a form of exercise you can overpay to partake in, it probably already is a form of exercise that you can overpay to partake in, it's hard to know where you should keep the nipples hidden and where you can let them roam free like cows in a pasture.

We're here to help. If we're talking like a public gym? No way. I have not actually met or seen anyone who thinks that this is okay, and so it's probably a moot point Worth noting: the legend in the back kept his shirt on and became the hero in a viral video. So let's just reiterate here for posterity's sake: if you go sans-blouse at the gym, you're like a guy smoking inside a subway car.

Is your secondhand smoke going to kill anyone? But why the fuck would you smoke in a subway car, you buffoon? If you don't want sleeves, lose 'em, no matter your build.

We are, however, in the business of barbed-wire-tattoo-shaming. So keep that in mind. Feels like a no. But, if you're waffling, consider the upside and the downside. Upside: you get to take your shirt off. A quick call to a SoulCycle here in New York—and a brief wait for the manager—revealed that SoulCycle has a no nipple policy.

This book is guaranteed to lift up readers and have them believing in the resilience and transcendence of the human spirit, making it a must read for years to come.

When reaching adolescence, most teenagers want more freedom, independence and control in their lives. For Arthur, it was the opposite, as he discovered that his lifespan would only last up to adulthood. After becoming an adult, Arthur was waiting for his death. It was at the eleventh hour, at the age of twenty-one, when Arthur was introduced to a miracle treatment, but only after the damage of iron overload from all the blood transfusion was done to his body.

Grateful to be given a chance to survive for a few more years, Arthur decided to do something with his life; to get married, buy a house and also to have children, knowing he had no prospect of any future for himself. At the age of sixty, Arthur and his wife Helen celebrated their thirty-five-year marriage anniversary. Recently we caught up with Bozikas so we could learn more about this amazing human and very talented writer.

Why was you story Iron Boy one that you felt you needed to share with the world? I promised myself if I made it to the age of 40 years old, I would put it all down in writing. I didn't know it will take me another twenty years to do it? When reading Iron Boy, the book struck me as a story on struggle, but more so about survival and endurance. How has that challenges you faced growing up helped shape you as an individual today especially as it pertains to business and entrepreneurship? This is the first of its kind worldwide, from the prospective of a patients' point of view and not from a specialist or doctor.

I wish I had something like Iron Boy when I was young and very afraid of my prospects! As a professional CEO for over twenty years, the challenges in business is that you need to equip yourself with the right information or you are dead in the water! People with my condition now do have my book to prepare for the future because there is one and it's up to the individual to believe! Being married for 35 years is a huge accomplishment, what is the secret to your success that you can share with younger couples looking to hopefully have the same success in their marriages?

I think if both couples feel like they can't wait to share a new idea with one another or are not prepared to go anywhere without their partner by their side, then this is the only secret that any younger couples must desire for a successful marriage!

These two examples will resolve all arguments that every couples get into a marriage too or later! From a life lesson perspective what are some of the key points that you hope others can take away from your story 'Iron Boy' and even more so what is something that you hope you leave behind to your children that you hope they can apply to their own lives? My children have been raised to see the person, and not the disability, that they have.

I would like for a life lesson that the world can refer to us as "people first" regardless the disability one has. People with a disability and not disabled people…always put "people" first.

See the person and not the disability! How do you feel now? How is life after the 'miracle' treatment and is there any message that you would like to share with others who are struggling with the same challenges that you faced but that you are also facing here today?

I feel very grateful and life is wonderful for me and my family. Although health issue will continue to always be a big issue for me, I will deal with them each one at a time. The important thing is that young people worldwide with my condition can inspire others to do great things would something I would love to inspire!

Tlacaelel was never an emperor himself but he was a cihuacoatl or a supreme leader and advisor. However, Tlacaelel was also the one who elevated Huitzilopochtli from a smaller tribal god into the god of Tenochtitlan and of the Aztec Empire. Before Tlacaelel, the Aztecs actually worshipped other gods much more vehemently than they did Huitzilopochtli.

Such gods included Quetzalcoatl, Tezcatlipoca , Tlaloc , the former sun god Nanahuatzin , and others. In other words, all the above mythos about Huitzilopochtli creating the Aztec people and leading them to Tenochtitlan were established after the fact. The god and large parts of its mythology existed before Tlacaelel but it was the cihuacoatl who elevated Huitzilopochtli into the main deity of the Aztec people.

As is written in the Florentine Codex — a collection of documents on the religious cosmology, ritual practices, and culture of the Aztecs — Tlacaelel I had a vision that the warriors who died in battle and women who died in childbirth would serve Huitzilopochtli in the afterlife. Wherever this palace is, the Florentine Codes describes it as shining so bright that the fallen warriors have to raise their shields to cover their eyes.

They could only see Huitzilopochtli through the holes in their shields, therefore only the bravest warriors with the most damaged shields would manage to properly see Huitzilopochtli. Then, both the fallen warriors and the women who died at childbirth were transformed into hummingbirds. It was devoted to the two most important gods for the Mexica people in Tenochtitlan — the rain god Tlaloc and the sun and war god Huitzilopochtli.

The temple is believed to have been expanded eleven times during the existence of Tenochtitlan with the last major expansion happening in 1, AD, just 34 years before the invasion of the Spanish conquistadors. This last upgrade was also celebrated with 20, ritual sacrifices of prisoners of war captured from other tribes.

The temple itself had a pyramidal shape with two temples sitting at its very top — one for each deity. When speaking about Aztec sun gods, we have to spare a mention for Nanahuatzin — the original solar god from the old Nahua legends of the Aztecs. He was known as the humblest of the gods. According to his legend, he sacrificed himself in fire to make sure that he would continue to shine over the Earth as its sun. His name translates as Full of Sores and the suffix —tzin implies familiarity and respect.

This can depend on the legend, however, as do some other aspects of Nanahuatzin and his family. For better or for worse, the Aztec empire simply needed a more war-like and aggressive patron god than the humble Nanahuatzin.

Huitzilopochtli is not just one of the most famous Aztec gods possibly second only to Quetzalcoatl who is very well-known today but he was also arguably the most influential one. The Aztec empire was built on a never-ending conquest and war over the other tribes in Mesoamerica and the worship of Huitzilopochtli was at the very heart of that.

The system of sacrificing enemy captives to Huitzilopochtli and allowing the conquered tribes to self-govern as client states in the empire had proved very effective up until the arrival of the Spanish conquistadors.

Ultimately, it backfired on the Aztecs as many of the client states and even members of the Triple Alliance betrayed Tenochtitlan to the Spanish. Barring that untimely end of the Aztec empire, the worship of Huitzilopochtli was definitely the driving force behind the Aztec empire. Symbolized by hummingbirds and eagles alike, Huitzilopochtli lives on to this day, as the emblem of modern-day Mexico still refers to the establishment of the city of Tenochtitlan. One notable pop-culture mention of Huitzilopochtli is the trading card game Vampire: The Eterna Struggle where he is portrayed as an Aztec vampire.

Given that the Aztecs literally fed Huitzilopochtli human hearts to keep him strong, this interpretation is hardly wrong. As one of the most influential Aztec gods that drove the need for more conquests and capturing of enemies, Huitzilopochtli was at the heart of the Aztec empire. Worshipped with fervor and constantly offered sacrifices, the Aztec sun and war god was a powerful warrior whose influence can still be seen in present day Mexico.

The hummingbird imagery is so important that it has become the defining feature of most depictions of Huitzilopochtli and one of the few ways to easily identify him among the Mesoamerican gods. Huitzilopochtli had quite a few different symbols. One of the major symbols with which he was associated with in both his bird and human forms was the hummingbird.

He was also closely associated with the sun, especially in his aspect as the warrior who fought against the darkness. Perhaps his most important symbol, though, was the capital city of Tenochtitlan. While most gods in Mesoamerica would be responsible for certain types of war or certain types of weaponry, Huitzilopochtli was responsible for all of it. As such, the Mexica attributed everything that happened on the battlefield to Huitzilopochtli — even if they lost.

It was a situation that saw a great deal of power handed over to the god. The other major power of Huitzilopochtli was his ability to fight back the encroaching night. While sun gods traditionally were associated with the cycle of the day, Huitzilopochtli had a more pressing duty. It was through him that an encroaching permanent could be fought off, and only Huitzilopochtli was mighty enough for this task.

Many of the major Aztec sacrifices were intended to help Huitzilopochtli fight off the darkness. It should also be noted that Huitzilopochtli was a god of the afterlife as well. If Aztec soldiers were killed in battle or women died in childbirth, they were said to join Huitzilopochtli.

Though he was not a death god, he did still have command of those souls that fell in those specific circumstances and they would serve in his palace. Huitzilopochtli actually has a fairly wide-ranging family in Aztec myth, though figuring out exactly to whom he is related requires reading specific stories. In the first story, Huitzilopochtli is the son of Tonacatecutli and Tonacacihuatl, the universal creators.

According to this myth, his brothers are two gods called Tezcatlipocas as well as Quetzalcoatl. In a different myth cycle, he is the son of the goddess Coatlicue. This myth cycled gives him four hundred brothers, the Centzonuitznaua, as well as a sister called Coyolxauhqui. Regardless of the myth cycle, Huitzilopochtli seems to have no children.

A dentist may take an X-ray of the teeth. X-rays do not always show where cracks have formed, but they can reveal problems in the pulp of the teeth. If the pulp of a tooth appears to be unhealthy, this can suggest a crack. Anyone who suspects that they have a cracked tooth should make an appointment with a dentist as soon as possible. It is especially important to do so when there are pain and discomfort.

The longer that a cracked tooth goes untreated, the more difficult it may be for a dentist to save the tooth. Complications may also occur, such as infection. Tooth cracks are more common in people over the age of 40, and women develop them more often than men. The smallest cracks are known as craze lines, and they develop within tooth enamel. A person is unlikely to notice a craze line, and no treatment is necessary unless it causes symptoms.

In the most severe cases, when a crack has penetrated the pulp of the tooth, root canal treatment may be necessary. If a tooth is badly cracked, a dentist may remove it altogether. If a tooth with a filling becomes cracked, a dentist may need to remove the filling to examine the damage more thoroughly.

Cracked teeth can cause complications, particularly if they are left untreated. For example, an infection may occur. Signs of infection include:.

If the event of infection, pus may need to be drained, and a person may need to take antibiotics.

Brush twice a day, floss daily, and visit your dentist every six months for preventive care. Always wear a mouth guard if you play contact sports, and use one while you sleep if you grind your teeth. Anti-inflammatory painkillers, like ibuprofen Advil, Motrin IB , can reduce swelling and pain. And make an appointment to see your dentist as soon as possible. Delaying treatment puts your mouth at even greater risk.

Cost will vary by how extensive the crack is and where you live in the country. Dental fees tend to be higher in big metropolitan areas. A cracked tooth is a common experience for many. A variety of procedures are available to save the tooth and your appearance.

While a crack can be repaired, a cracked tooth will never be percent healed, unlike a broken bone might be. But prompt treatment offers the best chance of saving your tooth and preventing infection and further damage. And while your mouth may be sore after the treatment, the pain should subside in a few days.

Home Protect my smile Oral health conditions Oh no, Is it a cracked tooth? Cracked tooth: common causes. Common causes of a cracked tooth A cracked tooth can be the result of many possible incidents. The following are the most common causes of a cracked tooth: Teeth grinding : Chronic teeth grinding , also known as bruxism, can cause cracked teeth due to repetitive stress and friction. These cracks may start out as minor stress fractures but can become more significant and painful over time if the root cause is not corrected.

Weak teeth : Weak teeth, characterized by long-term wear or erosion of enamel, or lost tooth structure from large fillings, are far more susceptible to cracks. This is due to a deficient tooth structure, unable to withstand the normal rigors that teeth endure. With this weakened tooth structure, cracks and fractures may occur more easily and even extend throughout the entire tooth.

Weak or eroded enamel can be a result of genetic factors as well as grinding, diet and certain health conditions such as acid reflux. To avoid this mishap, make sure to chew slowly and navigate pitted fruits and similar food items with care. Accidental blows to the mouth : A direct hit to the mouth can cause chipped teeth, fractures, and other serious oral injuries.

I added [code] tags to your previous post to make the indentation readable. So, you read the Daconta article. Did you try the code? One thing you may not realize is that StreamGobbler actually runs in a separate thread. This can be important. With the code you show, it's possible that the error stream's buffer is full with some message for you, but you're waiting to read from standard output first.

This creates a hang, since the process remains open and thus the standard output does not return null, at least until the error message has been read.

It's definitely a good idea to use StreamGobbler or something like it. Listing 4. While this approach will work, it is not a good general solution.

Thus, Listing 4. A better solution would empty both the standard error stream and the standard output stream. And the best solution would empty these streams simultaneously I'll demonstrate that later.

So, MediocreExecJavac works and produces an exit value of 2. Normally, an exit value of 0 indicates success; any nonzero value indicates an error. The meaning of these exit values depends on the particular operating system. A Win32 error with a value of 2 is a "file not found" error.

That makes sense, since javac expects us to follow the program with the source code file to compile. Thus, to circumvent the second pitfall -- hanging forever in Runtime. Under the Windows operating system, many new programmers stumble upon Runtime. Subsequently, they run into Runtime. As stated earlier, the error value of 2 means "file not found," which, in this case, means that the executable named dir. That's because the directory command is part of the Windows command interpreter and not a separate executable.

And the farther you pull the band, the heavier the resistance feels. The half-inch band is light and stretches super easily—I use this for small muscle groups, like triceps, biceps, and rear delts with exercises like the overhead triceps extension , bicep curl , and face-pull.

I use it for bigger upper-body muscles like my back, in exercises like rows and single-arm lat pull-downs. While the thickness of the band does determine how heavy it feels when you stretch it, you can also make the move feel easier or harder by playing with the length of the band.

While the majority of my gym time was spent using free weights, I also depended on cable machines for a lot of pulling work. Changing up the angle—pulling vertically and horizontally—makes for a more well-rounded strength training experience, Miklaus says. You can also place the anchor on the hinge-side of the door if you want the band to be, say, at chest height, or along the bottom of the door if you want it to be floor-level.

My apartment, though, has some pretty old and flimsy doors, so I decided to take my resistance band outside to my super-sturdy steel fire escape. I thread the resistance band through the openings on the stairs, or around the pole along the railing, which gives me a solid anchor—and a variety of pulling angles.

Depending on where I choose, I can do pull-downs, high-low rows, or horizontal rows. This pulley system has been huge for me, since the dumbbells I have at home are too light to row. This one has a unique appearance and looks a little tougher at a first glance.

If the site has indeed received a manual penalty, there will be a notice in the account, stating explicitly that the action was manual and specifying the reason for it.

Well, Google won't be too specific, but they'll give you a solid idea of where to look for the culprit. Identifying exactly what harmed your site is the first thing you have to do.

In case of onpage issues, you'll guess easily what caused it, since you probably realized the dangers when you tried that grey-hat technique. Off-page issues may result from both algorithmic changes and wrong link-building tactics — or intentional tricks of someone else wishing to harm your stats. If you have no idea what caused the Google penalty, check below these most popular violations and SEO tips for each.

Negative SEO is aimed at decreasing a competitor's site rankings in search engines' results. These activities typically include knowingly building spammy, unnatural links to the site, content scraping, and even hacking the site. Successful negative SEO attacks are rare, but when they do happen, they may cause a big ranking drop across a substantial number of keywords. Your website may be hurt by backlinks coming from spammy sources.

It could happen either as a result of you buying low-quality backlinks or as a result of your competitors attacking your website. Whatever the case, use SEO SpyGlass to generate your backlink profile and check for two things: a recent spike in the number of backlinks and a penalty risk for each of your backlink sources.

To see the links that contributed to a spike, switch to the Backlinks dashboard and sort the links by First Found Date in descending order. This will make the newest links appear at the top of the list so that you can investigate them quickly. Select the links and hit Update Penalty Risk to check how toxic the links are.

Before you disavow backlinks that appear risky, it's best to examine each of them manually. If the negative SEO attack you identified was based on backlinks, first try contacting owners of the linking domains and ask them to take down the toxic backlinks. In SEO Spyglass workspace, for each linking domain that you decide to disavow, right-click on it, and hit Disavow domains.

Make sure to select the Entire Domain disavow mode. You will get all the links to disavow in a single file which you will next upload via Google's disavow tool. Finally, after you disavowed backlinks that had caused the Google penalty, submit a reconsideration request to Google. You can do that by clicking Request a review in the Manual Actions sections in your Search Console account.

It's a good idea to submit a comment with the request, where you can describe the steps you've taken to fix the issue. Google will review your request, and you should get the issue resolved in a week or two max. Mind that keeping your backlink profile healthy is an ongoing effort, even after the SEO attack is over. Regular backlink audits are the best way to stay safe from a ranking drop. SEO SpyGlass is a great help to get updates for your link profile: it gives you progress graphs for both the number of backlinks in your profile and the number of referring domains.

An unusual spike in either of those graphs is a reason enough to look into the links that your site suddenly gained. Make sure to monitor other stats about your backlinks, such as anchor text distribution and its diversity.

You'll find these stats further down the Summary module. Scraped content is another common negative SEO technique, which includes copying a site's content to other websites.

Use Copyscape Plagiarism Checker to see if someone is copying your content to other websites or if your writers copy content from other websites — both are equally bad for SEO. All you need to do is enter the URL of your page to find out if there are any duplicates of it online.

Alas, there are no disavow tools for scrapers. You might want to reach out to whoever is stealing your content, but you probably realize they are unlikely to reply. A more effective way of dealing with the issue — especially if the scraping is systematic — is to report the scraper using Google's copyright infringement report. The use of http to exchange sensitive data with its visitors, passwords, files upload, all this can make your website vulnerable.

Check out Google's comprehensive guide on how to recover from a site hacking attack. On-page violations are something you can and have to control. They often come as wrong SEO moves, like leaving low-quality content, bad user experience, or tricky internal links.

Comment spam is a negative SEO technique that can measurably impact your rankings. Go through the pages of your site that allow user-generated content product reviews, blog post comments, forums and check for spammy comments. Remove the comments, ban the accounts, and consider implementing additional measures to prevent user-generated spam in the future. Use WebSite Auditor to look for redirects that take users "somewhere other than where they expected to go".

This will show you a full list of redirected pages along with the URLs they redirect to. Remove all unnecessary redirects. Ideally, use only s, and only in cases when the redirect makes sense for users. My search engine ranking drops significantly for almost every pages.

Clarity in your set-up is crucially important when working with proportions. We will return to this subject later. All right reserved. Web Design by. Skip to main content. Purplemath A ratio is one thing or value compared with or related to another thing or value; it is just a statement or an expression, and can only perhaps be simplified or reduced.

Content Continues Below. I'll cross-multiply, and then divide:. Affiliate WyzAnt Tutoring. Share This Page. Terms of Use Privacy Contact. Advertising Linking to PM Site licencing. Visit Our Profiles. In problems involving proportions, we can use cross products to test whether two ratios are equal and form a proportion. To find the cross products of a proportion, we multiply the outer terms, called the extremes, and the middle terms, called the means.

Here, 20 and 5 are the extremes, and 25 and 4 are the means. Since the cross products are both equal to one hundred, we know that these ratios are equal and that this is a true proportion. We can also use cross products to find a missing term in a proportion. Here's an example. Learning Objective s.

A true proportion is an equation that states that two ratios are equal. If you know one ratio in a proportion, you can use that information to find values in the other equivalent ratio. Using proportions can help you solve problems such as increasing a recipe to feed a larger crowd of people, creating a design with certain consistent features, or enlarging or reducing an image to scale. For example, imagine you want to enlarge a 5-inch by 8-inch photograph to fit a wood frame that you purchased.

If you want the shorter edge of the enlarged photo to measure 10 inches, how long does the photo have to be for the image to scale correctly? You can set up a proportion to determine the length of the enlarged photo. Determining Whether a Proportion is True or False. A proportion is usually written as two equivalent fractions. For example:. Notice that the equation has a ratio on each side of the equal sign. Each ratio compares the same units, inches and feet, and the ratios are equivalent because the units are consistent, and is equivalent to.

Proportions might also compare two ratios with the same units. For example, Juanita has two different-sized containers of lemonade mix. She wants to compare them. She could set up a proportion to compare the number of ounces in each container to the number of servings of lemonade that can be made from each container. Since the units for each ratio are the same, you can express the proportion without the units:.

When using this type of proportion, it is important that the numerators represent the same situation — in the example above, 40 ounces for 10 servings — and the denominators represent the same situation, 84 ounces for 21 servings. Juanita could also have set up the proportion to compare the ratios of the container sizes to the number of servings of each container.

Sometimes you will need to figure out whether two ratios are, in fact, a true or false proportion. Below is an example that shows the steps of determining whether a proportion is true or false. Is the proportion true or false? The units are consistent across the numerators. The units are consistent across the denominators. Write each ratio in simplest form.

Since the simplified fractions are equivalent, the proportion is true. The proportion is true. Identifying True Proportions. To determine if a proportion compares equal ratios or not, you can follow these steps. Check to make sure that the units in the individual ratios are consistent either vertically or horizontally.

For example, or are valid setups for a proportion. Express each ratio as a simplified fraction. If the simplified fractions are the same, the proportion is true ; if the fractions are different, the proportion is false. Example: International paper sizes like A3, A4, A5, etc all have the same proportions: So any artwork or document can be resized to fit on any sheet.

Very neat. Example: you want to draw the dog's head What was the normal price? Example: How tall is the Tree? But then Sam has a clever idea Example: you have just put 12 buckets of stones into a mixer, how much cement and how much sand should you add to make a mix? Let us lay it out in a table to make it clearer: Cement Sand Stones Ratio Needed: 1 2 6 You Have: 12 You have 12 buckets of stones but the ratio says 6.

Shortly after that, war broke out between Pisa and Genoa, another Italian city-state, halting construction for nearly a century.

By , it was leaning 5. That year, the monument was closed to visitors and the bells removed as engineers started extensive reparations to stabilize it. The straightening continued after the tower reopened in , and in sensors showed the subsiding motion had stopped, after a total improvement of some 19 inches.
