≈ 11.78 in
Step-by-step explanation:
The arc length is calculated as
arc = circumference of circle × fraction of circle
= 2πr × 
( cancel 2π on numerator/ denominator )
= 15 × 
=

Answer: C. 4
Step-by-step explanation:
First, we can prime factorize 52.
52 = 2^2 * 13
13 is not a square number, but 4 is a square number because it equals 2 squared.
Therefore, the correct answer is C. 4
Hey there!
Let's write an equation given this information. We will use x to represent the number.
2(x-7)=5
Now, we use the distributive property to remove the parentheses.
2x-14=5
Now, we add 14 to both sides.
2x=19
We divide both sides by 2.
x=9.5
Therefore, our number is 9.5
I hope this helps!
