Answer:

5+k = 11

Step-by-step explanation:

"Sum of a number" means addition.

"A number k and five" means you add the variable k and 5

"Is 11" tells you that the answer will be 11

You need to add K and 5 and get 11. Use this to set up an equation. Solve for K if need be. This results in k=6 but i believe that is not part of the prompt. Happy mathing ;)

What is the slope ?????

Scilla [17]

Answer:

The slope of the line is m = 3

Step-by-step explanation:

You can easily verify that if x decreases by 2 (e. g., from -4 to -2), y increases by 6. Thus, the slope is m = rise/run = 6/2 = 3

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

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.
