In one day, The Tool Shed rented out 25 self-propelled and riding mowers for a total fee of $900. The daily rental cost was $20 for each self-propelled mower and $40 for each riding mower. Find the number of self-propelled mowers (x) and the number of riding mowers (y) rented for that day. 5 self-propelled mowers and 20 riding mowers
18 self-propelled mowers and 7 riding mowers
8 self-propelled mowers and 17 riding mowers
12 self-propelled mowers and 13 riding mowers

Match each polynomial with its factorization.

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:

The triangles in the diagram are congruent. if mzf = 40°, mza = 80°, and mzg = 60°, what is mzb?
