3. there is 4 inches of water in the swimming pool before the day started. the rainfall is falling at 3 inches per minute. a. write an inequality for how much water is in the pool, let x represent the minutes. b. graph the inequality (just give me the points.)

In the diagram, the measure of angle 9 is 85° which angle must also measure 85°?

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:
