Answer:
C) about 113
Step-by-step explanation:
"How many people are there per square mile?" means that we want a ratio with miles as denominator. In other words, to find the population density, we just need to divide the population by the land area (miles squared):
![population-density=\frac{people}{land-area}](https://tex.z-dn.net/?f=population-density%3D%5Cfrac%7Bpeople%7D%7Bland-area%7D)
We know that the population of Alabama is 90,000 people and its land area is 800 miles squared, so
and
.
Replacing values:
![population-density=\frac{people}{land-area}](https://tex.z-dn.net/?f=population-density%3D%5Cfrac%7Bpeople%7D%7Bland-area%7D)
![population-density=\frac{90000}{800mi^{2}}](https://tex.z-dn.net/?f=population-density%3D%5Cfrac%7B90000%7D%7B800mi%5E%7B2%7D%7D)
![population-density=112.5](https://tex.z-dn.net/?f=population-density%3D112.5)
Which rounds to:
![population-density=113](https://tex.z-dn.net/?f=population-density%3D113)
We can conclude that there are approximately 113 people per square mile in Alabama.
Answer:
4cm
Step-by-step explanation:
![\sqrt[3]{64} = 4](https://tex.z-dn.net/?f=%20%5Csqrt%5B3%5D%7B64%7D%20%20%3D%204)
The edge length is 4cm.
