## Week 1- MondayPresentation Transcript

• Week 1: Monday Due Today: Arithmetic Advice for Writing 01 Critical Reading 01 Grammar 01
• Arithmetic
• Arithmetic
• Key Points, Rules 1
• Percentages:
• Percent to fraction: multiply by 1/100
• Decimal to Percent: shift decimal point two places to the right ->. Add % sign.
• Percent to Decimal: shift decimal point two places to the left ←. Remove % sign.
• Loss/Discount:
• Loss= cost price – selling price
• Cost price= Selling price + loss
• Selling price= cost price – loss
• Discount= List price- selling price
• Selling Price= list price – discount
• List price= Selling Price - Discount
• Key Points, Rules 2
• Ratio
• a/b or a:b. In a:b, a is antecedent & b is consequent.
• If two rations equal, then the four numbers are in proportion.
• Direct Proportion:
• If two variables vary in such a way that x/y is constant(k) then x and y vary directly.
• Inverse Variation
• If two variables , x and y, vary in such a way that x times y = constant (k) then x and y vary inversely.
• Key Points, Formula 1
• Quantity
• x = total amount,to express one quantity as a percent of the other.
• Increase by Percent
• x = percent, y = original amount. Formula to get the increased value is:
• Decrease by Percent
• x = percent, y = original amount. Formula to get the decreased value is:
• Key Points, Formula 2
• Loss
• Discount
• Key Points, Formula 3
• Interest
• NOTE: Please review Ratios, Direct Proportion and Inverse Variation through the lesson link.
• Practice is the best way to study for essays! At first they are hard, but improve over and over. There is a prompt I've taken from official and commercial SAT/ACT sites that I wish for you to practice writing an essay for. FIRST:
• Here is the instructions:
• Set aside 5 minutes. I recommend a stopwatch, online stopwatch , or even writeordie.com
• These five minutes is to create a quick outline of a thesis/point, purpose (entertain, persuade, inform, express), word count, format, a few supporting ideas, and a conclusion.
• Now set aside 10-15 minutes.
• This is to write for the prompt. This will actually be your essay.
• This will leave you with either 5 or more minutes to review your essay, correct grammar, and overall fix your essay.
• The essay portion of the test is usually 25 minutes, so remember that you want to have the best score possible but also be done by the time limit.
• Practice Prompt for essay
• Think carefully about the issue presented in the following excerpt and the assignment below.
• People assume that every accomplishment—each step in what we call progress—will lead to the solution to a problem and will help them reach the goal of understanding themselves and the world around them. In reality, however, each new answer provokes additional questions and each fresh discovery uncovers further complications. Every accomplishment leads to further problems, added responsibilities, more complications, and new challenges.
• Assignment: Does every achievement bring with it new challenges? Plan and write an essay in which you develop your point of view on this issue. Support your position with reasoning and examples taken from your reading, studies, experience, or observations.
