Answer:what do u mean by proportional?
Answer:
2nd quadrant
Step-by-step explanation
if an angle is between 90 and 180 degrees, it is in the second quardrant. since 0<x<90, 90+x will be more than 90 but less than 180, hence it lies in the second quadrant

Hello!</h2>
The answer is: The length of the ratio is 18 feet.
<h2>
Why?</h2>
There are two ways to calculate the circumference of a circle:

Since we are looking for the length of the radius, let's work with the second formula.
From the statement we know that the circumference of the cirble is 36π, so we need to isolate the ratio:

So, the length of the ratio is 18 feet.
Have a nice day!

Answer:
B. 1010
Step-by-step explanation:
<u>Simplify:</u>
<u>Note that:</u>
- ab = 10a +b
- ab0 = 10* (10a + b) = 10ab
- ab0ab = 1000ab + ab = 1001 ab
<u>Therefore:</u>
- (ab0+ab0ab) ÷ (ab) - 1 =
- (10ab + 1001ab) ÷ (ab) - 1 =
- (1011ab) ÷ (ab) - 1 =
- 1011 - 1=
- 1010
<u>Correct choice is</u> B.1010
