As of 2016, New York City has a population of 8.55 million and a land area of 300 square miles. Manhattan is a section of New Yo
sineoko [7]

Answer: 42804 people per square mile

Step-by-step explanation:

As we know Population density = \dfrac{Number\ of\ people}{Area}

Given, population of New York City =  8.55 million

Area of New York City  = 300 square miles

Then, population density of New York City = \dfrac{8.55\text{ million}}{300\text{ square miles}}

=\dfrac{8550000}{300\text{ square miles}}=28500\text{ people per square mile}   [1 million = 1,000,000]

Population of Manhattan =  1.64 million = 1640000

Area of Manhattan  = 23 square miles

population density of Manhattan = \dfrac{1640000}{23}\approx71304\text{ people per square mile}

Difference = 71304 - 28500 =42804

Hence, population density of Manhattan is 42804 people per square mile greater than that of New York City.

The New York museum attracted 6,274,289, while the Chicago museum attracted 5,772,857.

Round to the nearest million. Note that if the number in the hundred-thousands place value is 5 or greater, round up. If it is 4 or less, round down.

6,274,289 => 6,000,000

5,772,857 => 6,000,000

Combine the two terms

6,000,000 + 6,000,000 = 12,000,000

a) 12,000,000 is your answer

hope this helps
