The Horse Problem Math Challenge

The highly prized skills that employers look for today are problem-solving, reasoning and decision making, and logical approaches to challenges. Fortunately, mathematics challenges are the perfect way to hone your skills in these areas, especially when you challenge yourself to a new Problem of the Week each week like this classic listed below, The Horse Problem. Though they may seem simple at first, problems of the week from such sites as MathCounts and Math Forum  challenge mathematicians to deductively reason the best approach to solving these word problems correctly, but oftentimes, phrasing is meant to trip up the challenge-taker, but careful reasoning and a good process for solving the equation will help ensure you answer questions like these correctly. Teachers should guide students toward a solution to problems like The Horse Problem by encouraging them to devise methods for solving the puzzle, which might include drawing graphs or charts or using a variety of formulas to determine missing number values. The Horse Problem: A Sequential Math Challenge The following math challenge is a classic example of one of these problems of the week. In this case, the question poses a sequential math challenge in which the mathematician is expected to calculate the final net result of a series of transactions. The situation: A man buys a horse for 50 dollars. Decides he wants to sell his horse later and gets 60 dollars. He then decides to buy it back again and paid 70 dollars. However, he could no longer keep it and he sold it for 80 dollars.The questions: Did he make money, lose money, or break-even? Why?The answer:  The man ultimately saw a net profit of 20 dollars; whether you use a number line or a debit and credit approach, the answer should always amount to the same. Guiding Students to the Solution When presenting problems like this one to students or individuals, let them devise a plan for solving it, because some students will need to act out the problem while others will need to draw charts or graphs; additionally, thinking skills are needed for a lifetime, and by letting students devise their own plans and strategies in problem-solving, teachers are allowing them to improve these critical skills. Good problems like The Horse Problem are tasks that allow students to devise their own methods to solve them. They should not be presented with the strategy to solve them nor should they be told that there is a specific strategy to solve the problem, however, students should be required to explain their reasoning and logic once they believe they have solved the problem. Teachers should want their students to stretch their thinking and move toward understanding as math should be problematic as its nature suggests. After all, the single most important principle for improving the teaching of math is to allow math to be pragmatic for students.

The World Wide Web As A Practitioner s Perspective

According to Mark Pallen, â€Å"The world wide web is the crowning glory of the internet, providing a uniform, user friendly interface to the net.† The world wide web is the system that connects the internet together, and therefore connects the entire world. Without the interface of the world wide web, the internet would simply be a collections of ones and zeros, not the place of communication, learning, and collaboration it is. The world wide web was the most influential improvement of the 1990s because it globalized government, business, and the public, therefore connecting all aspects of life for Americans and people around the world even in modern day. Modern governments require communication, and the world wide web offers this to countries†¦show more content†¦With the possibility for public communication through the world wide web, governments also have to communicate. This newfound communication between governments, in reality, benefits the people most. In Geoffrey Garrett’s report on Globalization and Government Spending around the World, he argues that the world wide web helps to maintain honesty in the government and its policies, â€Å"The common metaphor of a globalization-induced race to the bottom suggests that governments are under heavy efficiency pressures to reduce their economic policy activism to promote competitiveness and to keep mobile capital within national borders.† Now that citizens have access to an abundance of information, the world wide web acts as a police to encourage the government to treat its citizens fairly. For example, in many dictatorships today, certain parts of the intern et, if not all, are restricted. These people do not get to use the internet and the communication that comes with it realize their own conditions are not just. The world wide web calls these governments to remember that the government is representing its own citizens, and therefore needs to suit its policies to its people. John H. Dunning calls forth the idea that globalization, especially thanks to the world wide web, calls governments to change policies to adapt to this new world in his paper, Governments, Globalization, and International Business, â€Å"In doing so they

Film Review for “An Anthopological Introduction to YouTube” Essay Sample free essay sample

Michael Wesch’s short movie â€Å"An Anthropological Introduction to YouTube† does precisely what the rubric entails- he introduces YouTube from an anthropological point of position. While many may hold issues believing of YouTube as anything other than amusement. Wesch does an exceeding occupation of linking these two topics. Wesch begins with presenting YouTube ; that is. he explains how YouTube truly got large. From the beginning of YouTube. he goes into demographics for YouTube. After this point in the picture is where Wesch starts to speak about communicating. peculiarly in societal media. Anthropology is the survey of human nature and human society. Anthropology aims to depict what it means to be human in a wide sense. Wesch. all from an anthropological base point of what it means to be human. covers how YouTube became a portion of today’s community. how it has the possible to destruct community. and how it builds community. First. it must be understood how YouTube has become a portion of today’s society. Wesch marks the â€Å"Numa Numa† picture as the grade of the start of YouTube. This picture gets popular in Italy. From Italy it goes to Europe in general. after this picture caputs to Japan and someway lands itself on a computing machine in a suburb of New Jersey. Harmonizing to Wesch. most of the picture on YouTube are homemade and intended for less than 100 people ; nevertheless. he besides states about 100. 000 of the 200. 000 pictures on Youtube are addressed to a YouTube community. This community can run from anyone to anyplace. Wesch references Robert Putman. writer of â€Å"Bowling Alone: America’s Declining Social Capital† . who’s thought is that community has been lost over clip. Over clip. locally owned ma and pop food market shops turn into Wal-Mart super shops on every corner. The face to face communications has been lost over the old ages. but people are get downing to replace it with societal media online. Social media has been turning and turning in present civilization. Websites like YouTube. Facebook. and Twitter are starting up and going progressively popular. The Associated Press did an article in 2012 coroneted â€Å"Number of active users at Facebook over the years† . In this article it shows drastic leaps in the figure of history holders. In 2004. the article reports merely one million users. but by 2008. there are 100 million users. The Numberss in September of 2012 are reported to hold been a sum of 1. 01 billion users. Now believing about Facebook. it is a site where people can pull off their friends. household. and anything else worthy plenty to hold a profile page. Anne McClard’s article â€Å"Focus on Facebook† explains â€Å"We find Facebook displacements identity-making on the web off from the individual†¦in a new manner. enabling low-maintenance. and automatically generated. interaction-based content creation† ( 2008: 1 ) . This low-mai ntenance communicating on Facebook is similar to other societal media web sites. including YouTube. With YouTube. a individual is able to sit stray and entertain themselves for hours with pictures on the web. This new societal media civilization should be destructing communicating. right? Well. ladies and gentlemen. the fact is that YouTube is besides constructing communicating through picture. As Wesch describes. there is this thought of cultural inversion. where one thing is expressed and another objet is valued. One illustration he uses is that while individuality is expressed. community is valued. Community. in this case. is something that is being longed for in many persons. including those on these societal media sites like YouTube. Wesch expresses the thought that when a individual negotiations into the camera on or in their computing machine. the speaker is in a sense speaking to everyone that is in the universe. The speaker has no thought of who will see their picture or when it will be seen. In add-on. the viewing audiences have a sense of being able to watch these pictures without anyone cognizing who they are. This. as Wesch describes it. aunomity gives the spectator the ability to watch. This spectator can gaze at the speaker and admire human nature. wher eas in world. viewing audiences can non gaze at person without being judged. Speakers have a opportunity to make a new individuality. perchance an individuality closer to who they feel they are in existent life. Viewing audiences can watch these pictures with the freedom to see this humanity without fright or anxiousness of being judged. and that is a beautiful connexion. YouTube is frequently thought of as a societal communicating site that has nil more than silly videos to do people laugh or video web logs done by a random cipher. The truth is. YouTube is an of import tool to today’s communicating. Although this media communicating is non every bit standard as the face to confront communicating of older times. it is still a communicating beginning that is used and touched by many. Wesch connects this new age communicating and ties it into the anthropological point of view. He does an first-class occupation in covering how YouTube became a portion of today’s community. how it has the possible to destruct community. and how it builds community.

Teacher and Softball free essay sample

Sports can be used to learn life lessons in ways that they help shape attitude, portray passion, develop personality, and teach companionship. â€Å"When life throws you a curve ball† means that when life gives you obstacles to overcome. This is a quote relating to life incorporating baseball or softball in to it, using â€Å"curve ball† as a synonym for obstacles. Softball, along with other sports, is a great way to learn life lessons and is not just a sport. A sport, such as softball, is something that many people can benefit from.

Softball also teaches people to have passion. I give a lot of recognition to the sport for teaching me to have passion not just in the game, but in life. Softball gave me something to be passionate about and also taught me to continue being passionate about other things such as my school work, and being successful. If I did not have softball in my life, I do not even know where I would be today because it was the first thing that I was passionate about. Since I was passionate about softball for all my life, it has given me great opportunities. The best opportunity it has given me is being able to go to a college that I love and also being able to play softball. If I wasn’t as determined and passionate about softball I would have not gotten the opportunity to play at Point Park University. Being an athlete of softball has taught me so much in life. Having a great attitude while laying a sport was not always easy; however, I knew that if I did not have a good attitude I would not do well. This idea, also, carried over to everyday life. If I did not have a good attitude when I woke up in the morning was like if I did not have a good attitude going up to the plate when I was up to bat. I knew I would fail if I did not have this positive attitude. Softball also can teach people to express themselves. I would not be the person I am today if I did not have softball to help shape the person I am. It taught me to communicate as a teammate and be respectful to the other team. I also interpreted this in to my everyday life. If I did not communicate on the field, or if I did not communicate with my friends I would not have successful relationships with people. Also, if I did not respect people, people would not show any respect for me. In conclusion, softball has not only helped me in life with teaching lessons and shaping me as a person, but it has helped a lot of other people as well. Softball, along with other sports, is an exceptional outlet for dealing with emotions and hardships, let alone also teaching great life lessons.

Lab report on Paper Chromatography essays

Lab report on Paper Chromatography essays 3. Materials and constituents page 5 The purpose of this lab report is to explain what exactly happened to the labs, the time that the experiment was executed and apply the results and conclusions that were deduced. Also, specify the errors that might have happened during the execution of the experiment. In the following experiment is going to be proved that a paper can separate a mixture of colours and that every colour reacts with a different way when put onto the paper strip. Chromatography is the name given to a method, which is very widely used for the separation of mixtures of chemicals and biochemicals, that depends on how fast a substance moves in a stream of gas or liquid past a stationary material to which the substance may be slightly attracted. Chromatography serves mainly as a tool for the examination and separation of mixtures of chemical substances. Chromatography is using a flow of solvent or gas to cause the components of a mixture to migrate differently from a narrow starting point in a specific medium. It is used for the purification and isolation of various substances. A chromatographically pure substance is the result of the separation. Because purification of substances is required to determine their properties, chromatography is an indispensable tool in the sciences concerned with chemical substances and their reactions. Chromatography is also used to compare and describe chemical substances. The chromatographic sequence of sobbed substances is related to their atomic and molecular structures. A change in a chemical substance produced by a chemical or biological reaction often alters the solubility and migration rate. With this knowledge, alterations or changes can be detected in the substance. In all chromatographic separations, there is an important relationship between the solvent, the chromatography paper, and the mixture. For a p...

Food and Its Impact on Health and Environment Research Paper

Food and Its Impact on Health and Environment - Research Paper Example The Double Quarter Pounder with Cheese: I have selected a very popular fast food item on the menu of fast food chains, the Double Quarter Pounder with Cheese. It is one of my favorite meals too but I have got to know many impacts it holds upon our health and long term living, also not to mention the impacts on animals and environment. A very popular documentary â€Å"Super-Size Me† was based upon the very similar issue. The maker of the documentary tries to gauge the impacts of fast food on his health and he goes on to eat McDonald’s meal every day three times for a period of 30 days. The impact it has on his health are enormous; he picks up a lot of fat and weight in the process. The doctors who had analyzed him said that he was also suffering from depression and anxiety and the meals had caused great damage to his heart. The documentary proved extremely shocking for many since it brought about the very true picture of how bad the impact of fast food is on our health. Composition of the Quarter Pounder: Now let’s delve into the ingredients of what makes a Double Quarter Pounder with Cheese so interesting. The double quarter pounder contains 4 oz. beef patty, 2 slices of cheese and a sesame seed bun. Well it is also served with barbeque and mushroom sauce on many occasions. The calories count is 740 which are very high on any scale in the world. Its nutrition grade is also D. The amounts of calories are predominantly fat and cholesterol. (Calorie Count) The Sourcing & Production of its Ingredients: The Beef Patty is composed of beef usually locally sourced depending upon the location of the food chains. The beef patty is composed of corn fed beef which gives it the crisp and color. A United Nations study has found that almost 18% of greenhouse gases come from the ranching and slaughtering of cows. Due to the various techniques of cow breeding and corn based feed, the beef is now much cheaper and fattier than ever before. (Ecoliteracy) The b eef processing is done by large conglomerates and a patty may contain meat form many different cows. The cows are bred in a very inhumane level and through different scientific treatments are grown bigger than their bones and body can sustain. After slaughtering, the beef is transported in its raw form to different places across the country where the beef is processed. The beef is processed in machines that bring together the mince and process them with corn to form patties. These patties are then hauled to local fast food producers where they are deep fried in oil and used in the burgers. The Cheese is very similar to this. Cows are given heavy dosage of stimulus and steroids to expedite milk production which not only causes diseases in animals but also decreases their life and may also transmit some of that in the milk too. The milk is then transported for further process where it is made into cheese and shipped to local food stores. Now a lot of fuel is being burnt in the process and global warming is one of the causes of fuel burning through transportation. On average a food related products has to travel almost fifteen hundred miles to reach to a store and this transportation accounts for about thirty eight thousand tons of greenhouse gas emission per annum. (Ecoliteracy) Health Impacts: 1 – Headaches The processed meat is contained in the burgers that is a cause of
