Your heart pumps about 5 quarts of blood through its chamber every 60 seconds. a swimming pool, holds 65,000 gallons of water. this represents the amount of blood pumped by your heart in approximately how many weeks?

First, we find out how many quarts of water is in a swimming pool, so we do the following:


And since we know the heart pumps 5 quarts of blood per 60 seconds, and there is a total of 260000 quarts to pump, we can find the amount of time it takes to pump the blood by doing the following:



so now we know that it takes 3120000 seconds to pump the blood. All that is left is find out how many weeks is equal to 3120000 seconds, so we do the following:


So the answer is approximately 5.16 weeks

Hello!

the answer is:

the answer is:

why?

to solve the problem, we need to remember the quotient of power property, it's defined by the following relation:

if we have a quotienf of powers that have the same base, we need to keep the same base and subtract the exponent of the denominator power to the exponent of the numerator power.

so, we are given the expression:

then, calculating we have:

hence, the answer is:

have a nice day!
