Homework #2 due 9/8/06

Today in math class we discovered (using the percent proportion) that only 18.5% of your school year will be spent on math instruction and that’s not including days out of the classroom for trips! We calculated that in the 180 day school year (36 weeks or 180 * 6.5 = 1170 hours) you only receive 6 hours of math instruction per week (45 minutes * 8 periods per week). We used these numbers to calculate the percent of math instruction you receive by using the percent proportion. (Part over whole equals percent over a hundred).

For homework this evening (9/7/06) you will find the percent of a regular year (365 days) that you waste.

1. Think about the number of hours per day you play (outside or video games), watch tv, use the computer (for IM’ing or fun) or generally waste time.
2. Use the number you found in #1 to calculate the total number of hours in a year you waste if there are 365 days in a year.
3. Calculate the total number of hours in one year.
4. Determine the percent of the year you waste by using the information you found in #'s 2 and 3 applying the percent proportion.
5. Calculate the percent of year you waste sleeping too!
