2. A 30,000 gallon tank is being filled with water. Before you start there are already 12,000 gallons of water in the tank. The hose fills the tank at a rate of 4000 gallons per hour. Part A: Write an equation that can be used to determine the number of hours it takes to fill the tank. Let h represent the number of hours the hose is running. Let g represent the total gallons that are in the tank. Part B: Suppose you start filling the tank at noon. By what time will the tank be completely filled? A. 4:00 pm B. 5:00 pm C. 7:00 pm D. 8:00 pm​

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:
