As of mid-2016, the world's population was about 7.4 billion people. The population of the United States was 324 million. The land area of a certain state is about 261,787 square miles. If in mid-2016 all of the world's people were put into that state, how many people would there be in each square mile? (Round your answer to the nearest whole number.)

There would be approximately 28,267 per square mile.

Step-by-step explanation:

There are 7,400,000,000 people in the world. The state is 261,787 square miles.

7,400,000,000/261,787 = 28,267.2554 → 28,267

step-by-step explanation:

12: 00 p.m. to 7: 00 p.m. is a total of 7 hours.

4: 00 p.m. to 7: 00 p.m. is a total of 3 hours.

this means that from 4: 00 p.m to 7: 00 p.m. this represents 3/7 of what was lost from 12: 00 p.m. to 7: 00 p.m.

after knowing this, after doing 11,600 - 6,800 = 4,800

4,800 represents 3/7 of what was lost for 7 hours.

we then divide 4,800 by 3 which gets 1,600.

because we know that 1,600 represents 1/7 of how much water was lost, we just have to multiply by 7, which gets 11,200.   after adding 11,200 to how much water was left at 7: 00 p.m. which was 6,800. 11,200 + 6,800 = 18,000

this means that the pool originally had 18,000 gallons in the pool.

you can also check your work by doing 18,000 - 4(1600), which becomes           1800 - 6400 which gets you 11,600.
