Answer:
We use formula, circumference= 
to get r= 7.48
Step-by-step explanation:
Here is the complete question: The circumference of a pool is 47 feet. Which formula can you use to find Radius (r), if you know that C =2πr.
Given: Circumference= 47 feet.
We will use formula of circumference to find radius (r) as given.
Circumference =
⇒ 
(∵ we know π=3.14)
Cross multiplying both side to get r.
⇒ r= 
∴ radius (r)= 7.48
∴ We will use circumference formula to find Radius (r).
Answer:
C. 
-6n+5
Step-by-step explanation:
Area of a rectangle =l x w
A=(n-5)(n-1)
Use distributive property
-n-5n+5
Combine like terms
-6n+5
Answer:
8x^2-1
Step-by-step explanation:
8x^2-x+4+x-5=8x^2-x+x+4-5=8x^2+4-5=8x^2-1
3600(total saving)/24(amount of months)=150(amount of dollars saved each month)
3600/24=150
In order to divide, you need to find the reciprocal of 4/15 and multiply it by 2/3. So, 2/3*15/4
The answer is 5/2
