Step One
Calculate the number of feet traveled in 1 rotation.
Formula
C = π*d
P = 3.14
d = 9 inches = 9/12 feet = 3/4 of a foot.
C = 3.14 * 3/4 = 2.355 So that means that every time the tire turns around 1 complete turn, the distance traveled on the ground is 2.355 feet.
Step Two
Figure out the number of revolutions.
1 revolution = 2.355 feet
x revolutions = 300 feet.
1/x = 2.355/ 300 Cross multiply
2.355 feet * x = 1 rev * 300 feet
2.355 x = 300 rev Divide by 2.355
x = 300 / 2.355
x = 127.39 revolutions. <<<< Answer
The lower left corner is the answer.
Angle 1 is congruent to angle 5 because they are alternate interior angles (assuming AB || DE)
They are on the inside of the parallel train tracks. By "train tracks" I mean the horizontal lines AB and DE. So they are considered interior angles. They are on alternate sides of the transversal AE. Angle 1 is on the right side while angle 5 is on the left side. These two facts are why they are considered alternate interior angles.
For this case we have that the inverse variation is defined as:

Where:
k: It is the constant of proportionality
According to the statement we have:

We find the constant of proportionality:

Then we find the value of x when
:

Answer:

To round to the nearest ten million, check the millions digit after it:
2 , 0 2 4
The millions digit is 4, so you will round down to 0. All digits after this number will be converted to 0.
Rounded to the nearest ten million, the number becomes 2,020,000,000.
The correct answer would be 3.65.
