An issue of a magazine contained the following statement. dropping less than two inches per mile after emerging from the mountains, a river drains into the ocean. one day's discharge at its mouth, 2 trillion gallons, could supply all of country a's households four months. based on this statement, determine how much water an average household uses each month. assume that there are 100 million households in country a.

5000 gallons of water will be consumed each month.

Step-by-step explanation:

One day's discharge at its mouth = 2 trillion gallons = 2× gallons of water.

This amount of discharge could supply all of country's households for the time = 4 months

So consumption in one month =

If the numbers of households in the country A are 100 million or

So water consumption by each household in one month

=

=

=

= 5000 gallons

5000 gallons of water is consumed by each household in a month.

then, the surface area of the sphere shown in the image is: 256π sq. units!

step-by-step explanation:

the lateral surface area of a sphere is 2πrh where h=2r.

then:

surface area = 4πr^2.

in this case, r=8 units ⇒ surface area = 4π(8 units)^2. = 256π sq. units!

then, the surface area of the sphere shown in the image is: 256π sq. units!
