Glenn can clean pools at a constant rate of 2/5 pools/hour.
1. What is the ratio of pools to hours?
2. How many pools can Glenn clean in 10 hours?
3. How many pools can Glenn clean in 15 hours?
4. How long does it take Glenn to clean 12 pools?

What power can you write to represent the volume of the cube shown? write the power as an expression with a base and an exponent and then find the volume of the cube

I’m still confused on how to work the percentages

Ascientist places 24 cells in a petri dish. she knows the cells grow at an exponential rate, doubling in number every hour. how long will it take (in hours) for there to be 1100 cells in the dish? time to 1100 cells: 5.51832530 hours how long will it take to reach 110 cells? time to 110 cells : 2.1963972 hours what is the average rate of change in the number of cells between 9 hours and 11 hours? average rate of change: cells per hour what is the instantaneous rate of change after 7 hours? instantaneous rate of change: cells per hour note: you can earn partial credit on this problem.
