Algebra in Business and Science
Algebra is used repeatedly in business and science for professions ranging from accountants to astronomers and physicists. The fundamental algebraic equation in accounting is assets = liabilities + capital. Accountants use this equation to balance the books. They also use algebra to calculate journal entries for interest payments and depreciation (Moore, n.d.). To analyze and work with numbers, accountants also need to understand positive and negative numbers, fractions and decimals. Other businesses that use algebra include retail stores, car dealerships and restaurants to name just a few. Each of these types of businesses sells a product and needs to calculate percentage discounts, sales or meals tax and profit margins. For science, algebra is used in astronomy, physics and chemistry. Astronomers and physicists use algebra to research and understand the universe. They observe, measure, interpret and develop theories to explain what is happening in the universe (US Bureau of Labor, 2009). One way that chemists use algebra is when mixing together chemicals. They need to calculate the correct amount of each substance to obtain the desired result. Algebraic Concepts in Everyday Life
The following are examples that I learned from the course discussion board of different ways that algebra can solve everyday life problems. ∙ To determine each person’s share of the cost for a limo ride, you would add a tip to the cost of the limo and divide by the number of riders. For example, if there were 10 kids riding in a limo and the cost of the limo was $600 (including a 20% tip), each person would pay $60. ∙ To split the cost of a restaurant bill, you would add a tip to the bill total and divide by the number of diners splitting the bill. ∙ To calculate a batting average in baseball use the following formula: Batting Average = # of hits / #of at bats. ∙ To calculate the cubic feet of a refrigerator when the height in cubic...

Introduction
Algebra, some of us fear it while some of us embrace it, algebra is not “arithmetic with letters” it is better described as a way of thinking. At its most fundamental level, arithmetic and algebra are two different forms of thinking about numerical issues. Many of these examples have been taken from our classroom discussions while others are examples I have discovered in my own research for this paper, several examples of each will be cited.
“Let’s start with arithmetic. This is essentially the use of the four numerical operations addition, subtraction, multiplication, and division to calculate numerical values of various things. It is the oldest part of...

A cheetah can run 76 km/h. The fastest human can only run about 37 km/h!
3.
The scale balances because the mass on the left side is equal to the mass on the right side. A number sentence can be written to describe the picture: 10 + 10 + 1 = 10 + 5 + 5 + 1 or 2 × 10 + 1 = 2 × 5 + 10 + 1 . a. Draw 3 different combinations of masses on a scale that would balance.
b. Write a number sentence to describe each of the 3 new combinations.

...a psalm of life
A Psalm of Life  
by Henry Wadsworth Longfellow 

What the Heart of the Young Man Said to the Psalmist Tell me not, in mournful numbers, "Life is but an empty dream!" For the soul is dead that slumbers, And things are not what they seem. Life is real! Life is earnest! And the grave is not its goal; "Dust thou art, to dust returnest," Was not spoken of the soul. Not enjoyment, and not sorrow, Is our destined end or way; But to act, that each tomorrow Finds us farther than today. Art is long, and Time is fleeting, And our hearts, though stout and brave, Still, like muffled drums, are beating Funeral marches to the grave. In the world's broad field of battle, In the bivouac of Life, Be not like dumb, driven cattle! Be a hero in the strife! Trust no Future, howe'er pleasant! Let the dead Past bury its dead! Act,act in the living Present! Heart within, and God...
...Why is algebra important in the realworld? The first reason algebra is important in the realworld is because people use algebra every day in their jobs. Having the ability to learn and do algebra will probably help you exceed into the job you want to do one day. Most people do not realize that algebra is used almost every day in adult life. Some examples of obvious jobs that use algebra are engineers, mathematicians, teachers and scientists. I believe everyone uses some sort of algebra in their jobs or their daily life adventure whether they know it or not.
Algebra is a huge part of our lives. Whether we drive a car and need to calculate the distance and mileage of a trip. Working out equations of how many miles per gallon your car will get is also a very important daily issue. What is you are working in a retail store as a cashier, would you use algebra? You would use algebra to determine coins and bills in change you use. In that case, the different bills and coins are your x’s and your y’s. Most people want think of that as algebra but that’s what it is.
There are some jobs that you would not think that would use algebra. Algebra can be used to determine what dimensions to use to make a box...
...challenges and move into the world. This is shown by a personal battle with their inner self, personal choice leading to a change in their emotions, different people having different ways of adapting to new challenges, individuals trying to shut off the rest of the world and the help of others an individual's attitude will change as they enter the world. This is shown the the novel The story of Tom Brennan by J.C Burke and in the movie Shrek by (director)
An individual's personal battle with their inner self may hold them back as they try to overcome challenges and enter into the world. The author uses flashbacks throughout the novel from Tom's perspective. These are of the night of the accident and show the reader that Tom is affected by the actions of his brother on that night. It also shows that Tom is held back and has a hard time overcoming the challenges that he faces due to these memories. The use of dialogue between Tom and Chrissy is used when Tom opens up about why he doesn't like to visit Fin. This conversation shows the reader that he is finally opening up about his old life that has help him back for so long. By Tom talking about this with Chrissy he has changed his personal choice and decided he doesn't want to be held back by his old life anymore. Once a person gets control of their inner self then they overcome challenges that they face in their new life...

12. When you flip a light switch, the light seems to come on almost immediately, giving the impression that the electrons in the wiring move very rapidly.
Part A: In reality, the individual electrons in a wire move very slowly through wires. A typical speed for an electron in a battery circuit is 5.0x10 to the 4th meters per second. How long does it take an electron moving at that speed to travel a wire 1.0 centimeter, or 1.0x10 to the 2nd?
Part B: Electrons move quickly through wires, but electric energy does. It moves at almost the speed of light, 3.0x10 to the 8th meters per second. How long would it take to travel 1.0 centimeters at the speed of light?
Part C: Electrons in an ordinary flashlight can travel a total distance of only several centimeters .suppose the distance an electron can travel in a flashlight circuit is 15 centimeters, or 1.5x10 to the 1st meter. The circumference of the earth is about 4.0x10 to the 7th meters. How many trips around the earth could a pulse of electric energy make at the speed of light in the same time an electron could travel through 15 centimeters of a battery circuit in 5.0x10 to the 4th meters per second?
For part A, the first step is to put (5.0) to the 10th to the 4th. The numerator would be (0.00050) if someone were trying to put 5.0x10 to the 4th in the form it’s supposed to be in. For the second scientific...
...Contracts: How They Effect EverydayLife
BUS 311 – Business Law I
Prof. Katheryne Rogers
January 6, 2012
Most people in society think that contracts are pointless and unnecessary. Contractual law is not high on society’s list of things to study. What society does not realize is that contracts bind a majority of the decisions that they make on a systematic basis. In this paper I will make evident the effectiveness of contracts and how they are such an immense aspect in society’s everydaylife.
This paper will demonstrate the practicality of contracts and how they influence and add to everydaylife. I am also going to show what would happen if we did not have any contract regulatory resolutions made. Without contracts; the law would not be able to make a verdict as to who to rule for if something were to come up; which transpires daily all over the world. The definition of a contract is basically an agreement between two or more persons. This explanation integrates countless things. Almost everyone in today’s society is a consumer. Just by being a consumer you make choices based on issues that have been put in place by contracts.
To show how crucial contracts are; a consumer awakens in his home; which he purchased from K.B Homes. K.B home is a company that is well known for designing homes. The consumer’s house was built by contractors. By differentiation a...
...Stress and everydayLife
Everyone has used the word “stress” before, what is it, and why is it a commonality upon the population in the western world. The word stress is defined “Physical, mental, or emotional strain or tension”. 1 Has Selye, a pioneering endocrinologist, coined the original definition of the word stress, in the midtwentieth century. 2 But why do we get stressed? It seems that the modern worlds business culture is the main feed for stress. The long hours working in a office, not knowing if your going to be fired or not, or even having a very disruptive supervisor can bring common stress to everybody; the main source of stress can revolve around the ever so threatening “deadlines” that can make or break people. We all know what it feels like to be stressed, and all the immediate effects of being stressed, but why do we keep on doing this to ourselves. 3
The stock market is a perfect example on how today’s business culture inflicts stress to the business men and women out there on the floor. The stock exchange where people can loose all their money in a blink of an eye or become a millionaire in the same amount of time. There are countless accounts of people getting trampled on because of 2000 other people wanted to get their money. Even though this is a risky market for money people still flood the floors every day of the week. We have to stand back and remember October 29, 1929 Black Tuesday,...
