The population of the US is about 3.02 X 10^8, and the average American uses about 1.5x10^2 gallons of water per day. Could this lake supply the American population with water for 1 day?

depends on the size of the lake.

What lake? How many gallons?

To determine if the lake could supply the American population with water for one day, we need to calculate the total amount of water the population would consume and compare it to the amount of water in the lake.

First, let's calculate the total amount of water the American population would use in one day. We'll multiply the average water usage per person by the population:

Total water usage = (average water usage per person) × (population)

Total water usage = (1.5 × 10^2 gallons/person) × (3.02 × 10^8 people)

Now, let's simplify the calculation:

Total water usage = (1.5 × 3.02) × (10^2 × 10^8) gallons

Total water usage = 4.53 × 10^10 gallons

Next, we need to determine the amount of water in the lake. Since you didn't provide the volume of the lake, we cannot calculate whether it can supply the water for one day or not. Please provide the volume of the lake in gallons, and I can help you with the calculation.
