Answer:
C 117
Step-by-step explanation:
<2 = 63
<4 = <2 vertical angles
<4 + <7 = 180
63 + <7 = 180
subtract 63 from each side
<7 = 117
We can write an equation of this, with p representing the unknown population. We know that 90% of the population owns cars:
90% * p
We also know that 4761 people own cars, which is the same as the above expression, so we write:
90% * p = 4761.
From there, you just divide both sides by 90%, or 0.9
p = 4761/0.9 = 5290
The population is 5290 people.
Answer:
When two variables are directly or indirectly proportional to each other, then their relationship can be described as y = kx or y = k/x, where k determines how the two variables are related to one another.
Step-by-step explanation:
This k is known as the constant of proportionality.
