In the funny elementary school cafeteria, lunch for 100 people is served. but it is topsy turvey, and the waiters are acting funny. the first waiter turned every plate upside down. then another waiter turned every other plate. then the third waiter turned every third plate (so if a plate was upside down it was placed normally, but if it was placed normally, it became upside down). the fourth waiter turned every fourth plate, and so on, until the hundredth waiter turned the hundredth plate. at the end, how many plates were placed normally?

it would to have a graph or something ! but i had this question so its false

step-by-step explanation:

5   1/4   miles per hour

step-by-step explanation:

15   3/4 / 3 = 5   1/4

so a parallelogram is just like a square base times height. multiply 40 and 39 to get 1560 inches.

a triangle is base times height divided by two. so multiply 7.9 and 5 and then divide it by 2 to get 19.75inches.

the kite can be split into two separate triangles and added together to get the total area. 30 x 4 /2 which equals 60. make sure to double it for the two triangles making 120.
