What do you mean this sentence?
the time a pump takes to drain the pool varies inversely with the power in watts of the pump,
The meaning would be : if we have a power in watts greater the time to drag the pool will be less because the relation between power and time is inverse.
40 watts--------------5 hours)
100 watts------------ x
because the relation between power and time is inverse, we multiply directly.
40 watts(5 hours)=100 watts x
x=(200 watts hours) / 100 watts=2 hours.
Answer: the time would be 2 hours. (the new pump is faster)
Answer:

Step-by-step explanation:
Y=mx+b is what I learned and point slope is y-y1=m*x-x1
1235 / 100
See 1235 as 1235.0, since we are dividing by 100, we have two zeros, so we move the decimal point in 1235.0 two places to the left.
12.35
21515754 people total* 0.38= 8175986.52 people
