Solution. We can assume there are 10 people in the class. Then there will be 1 junior and 9 seniors. The sum of everyone's scores is 10*84 = 840. Since the average score of the seniors was 83, the sum of all the senior's scores is 9 * 83 = 747. The only score that has not been added to that is the junior's score, which is 840 - 747 = 93.2016 AMC 10B Problems. 2016 AMC 10B Answer Key. Problem 1. Problem 2. Problem 3. Problem 4. Problem 5.

Since they are asking for the "ratio" of two things, we can say that the side of the square is anything that we want. So if we say that it is 1, then width of the rectangle is 2, and the length is 4, thus making the total area of the rectangle 8. The area of the square is just 1. So the answer is just 1/8 * 100 = 12.5.Amc 10b 2013 Art Of Problem Solving, Curriculum Vitae Da Compilare E Scaricare, Essay Just Lather Thats All, Professional Blog Post Ghostwriting Sites Ca, Write My Best Creative Essay On Hacking, How To Write A Memorandum University, Top School Thesis Proposal Sample2013 AMC 10B Problems/Problem 12.
