Water should be greater than 946.11 gallons per week to prevent the pool from drying.
Step-by-step explanation:
You have an outdoor swimming pool that is 5.0 m wide and 12.0 m long.
The height of water evaporated is = 2.35 inch
We will convert this to m.
1 inch = 0.0254 meter
So, 2.35 inch = meter
Now, volume of water in the pool = cubic meter per week.
1 cubic meter = 264.172 gallons
So, 3.5814 cubic meter = gallons
Hence, the volume of the water that should be poured in the swimming pool should be greater than 946.11 gallons per week to prevent the pool from drying.
The answer is $3000. You first want to set up a proportion, so 750/9000=1000/x. Then you will cross multiply to get (9000)(1000)=750x. Divide both sides and you will get x=12000. However, the question is asking how much is remaining, so we want to find the difference of 12000 and 9000, which ends up being $3000.
