Answer:
All of them are not vertical angles.
Step-by-step explanation:
Because they are not directly vertical from each other.
Answer:
The relationship between the circumference of a circle and its diameter represent a direct variation and the constant of proportionality is equal to the constant 
Step-by-step explanation:
we know that
A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form 
where K is the constant of proportionality
In this problem we know that
The circumference of a circle is equal to

therefore
the relationship between the circumference of a circle and its diameter is a direct variation and the constant of proportionality is equal to the constant 
It’s 58 because the length is increasing by 14
Answer:
<u>Slope</u><u> </u><u>is</u><u> </u><u>4</u><u>/</u><u>3</u>
Step-by-step explanation:
Slope is the derivative of the equation:

At point (5, 7), x is 5:

- The distance travelled by both Evelyn and Ricky is 45 miles
If Speed = dist/time, then;
<u>dist = speed * time</u>
<u />
We also know that both of them travel the same distance, so we equate the distance travelled to each other
36 * x+45 = 72 * x
36x + 1620 = 72x
72x - 36x = 1620
36x = 1620
x = 1620/36
<u>x = 45 miles</u>
<u />
