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:
<em />

So the answer is approximately
5.16 weeks
Answer:
500 students
Step-by-step explanation:
subtract all of the smaller numbers from the big numbers for each school.
school A = +530
school B = +480
school C = +490
530 + 480 + 490 = 1500
1500 ÷ 3 = 500
:)
You can because it has more then one equal sign
Answer:
324
Step-by-step explanation:
The shirt would be the same value because they are the same so
288÷3=96
Pi Shirt = 96
then work out the 3rd one to find out the balloons
98+ balloon + balloon= 226-96=130÷2= 65
Balloons = 65
then work out the 2nd one 195÷65=3
Pizza = 3
Then 4th one
25+1=26-3=29
Maccoroni = 29
Last question
96×3+65-29=324
