at the beginning of summer, a maintenance crew refills a swimming pool at a city part. the relationship between the time in hours to fill the pool and the amount of water in the pool is proportional. after 4 hours, the pool holds 5,200 gallons of water. b. the same crew refills a second pool as represented by the graph shown. is the second pool filled at a faster or slower rate than the first pool? explain.

Find the quotient with the restriction.

The school track has eight lanes. each lane is 1.25 meters wide. the arc at each end of the track is 180. the distance of the home straight and the radii for the arcs in the 1st 4 lanes are given. s=85m r1=36.5m r2=37.75m r3=39m r4=40.25m part one: find the radii of lanes 5 through 8 of the track. show your work. part two: if max ran around lane one, how far did he run? show your work and explain your solution. part three: max wants to run a total of three laps around the track, choose two additional lanes (2-8) for him to run and find the distance around those two lanes. show your work and round to the hundredths. part 4: based on your lane choices in part three, what was the total distance max ran in the three laps around the track?
