Gina and 7 friends are sharing 74 pipe cleaners for an art project. What is one quick way that Gina could figure out about how many pipe cleaners each girl would get to do their art project? Answer
A
She could think 74 is about 70, so 70 plus 8.

B
She could think 74 divided by 7.

C
She could think 74 is just over 72 and 72 divided by 8.

D
She could think 74 is about 75 and divide 75 by 8.

You drop a rubber ball off the roof of a 50 meter high building onto a paved parking lot. it bounces back up with every bounce, but not quite all the way back up to you. after the first bounce it bounces back only 80 percent of the distance it was dropped from. the pattern continues, meaning after every bounce it comes up to just 80 percent of the previous maximum height. so if before the first bounce the height is 50 meters, what height does the ball reach after the fifth bounce? round your answer to one decimal place and chose the correct response from the choices below:
