Help please! This has to do with the Pythagorean theorem.

Five more than the product of a number n and 8 is at least 100. write an inequality that can be used to find all positive values of n

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:

Which shows a reasonable estimation for 124% of 42 using the distributive property?
