Answer:
Given - Radius of ring is 9 millimeters
To find - Circumference
Solution -
9 millimeters = 0.9 centimeters
Circumference of circle = 2 × pie × r
= 2 × 3.14 × 0.9
= 6.28 × 0.9
= 5.652
Answer:
The distence bettween the two cities is 630miles
Step-by-step explanation:
So you take 42 and multiply it by 15 and you get 630.
Consider the function
First, factor it:

The x-intercepts are at points 
1. From the attached graph you can see that
- function is positive for

- function is negative for

2. Since
the function is neither even nor odd.
3. The domain is
the range is
330/3= 110
550/110=5
Answer is 5 books
Answer:
From the given figure we can see that :---
MN||PO, MN=PO and MP=NO
Therefore, angle M=angle N (adjacent sides of the trapezoid)

angle M=angle N= (6×18)+20=108+20 =128°
angle O =(180°-128°)=52°
<h3>Hence, angle O is <u>52°.</u></h3>
