Answer:
2500 people PER square mile
Step-by-step explanation:
THe population density is the population per unit area.
Here,
Given:
Population = 400,000
Total Area = 160 sq. miles
To get population density, we would need the population PER UNIT AREA, per miles.
We can get that by dividing the total population by total area:
400,000/160 = <u>2500 people PER square mile</u>
This is the population density.
Answer:
3/4
Step-by-step explanation:
plug values in for x till you get it right
34 you do 17×2 and get what you multiplily that by 0 .5
There are a various of ways solve this expression. We can choose to do completing the square method or to use the quadratic formula. In this case, I will choose to do completing the square. We do as follows:
<span>x^2 - 7x = -13
</span><span>x^2 - 7x + 49/2= -13 + 49/2
(x - 7/2)^2= 23/2
</span>√[(x - 7/2)^2]= √(23/2)
x-7/2 = √46 / 2
x = √46 / 2 + 7/2
Hope this answers the question. Have a nice day.
