Enter an equation that can be used to solve this problem, where x represents the number of hours that roberto had been traveling. roberto left his parent's house at 11 a. m. traveling at an average rate of 30 mph. his parents left their house at 12 p. m. traveling at an average rate of 45 mph going the same way as roberto so that they could catch up to him. after how many hours will it take roberto's parents to catch up to him? enter the amount of hours after roberto left that it will take roberto's parents to catch up to him (assume that they do not stop). equation: h

Subtract 8 1/6 - 4 5/6 . simplify the answer and write as a mixed number.

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:
