Start with the first sentence, and the definition of the area of a rectangle:
l * w = 36
Rewrite the equation to get
l = 36 / w
or
w = 36 / l
Either one shows the inverse relationship between w and l.
Assuming the last part wants you to write an equation for an x-y graph, the equation would be
y = 36 / x
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:
16 is answer
Step-by-step explanation:
3(2)^2+4(1)^2= 3(4)+4(1)=12+4=16
Answer:
-25
Step-by-step explanation:
C=5p+125
-125=5p
-125/5=p
-25=p
Therefore, p= -25
