Answer:

Step-by-step explanation:
The problem could be simplified as following:
Given:
The radius of a circle O is 26 feet.
Solve for:
The length of arc on circle O that measures 13 radians
Solution:
Step 1: Let's find out the correct formula to apply:
The formula to calculate the length of an arc measuring x radians on a circle with radius r feet is:
L = r*x
Step 2: Let's put the data into formula to work out the length L of arc:
L = 26*13 = 338 (ft)
=> The distance that a horse does on the outer edge travel when the carousel rotates through 13 radians: L = 338 (ft)
Hope this helps!

1/7+2x/3=(15x-3)/21 make all terms have a common denominator of 21
3+14x=15x-3 subtract 3 from both sides
14x=15x-6 subtract 15x from both sides
-x=-6 divide both sides by -1
x=6

Answer:
= <em>1</em><em>4</em>
Step-by-step explanation:
So my way of doing it is to simply put 20% in decimal so
20= 0.20
Then multiply that by 70
0.20× 70 = 14%
There are probably other ways to do it but I find this way easier
8 * 4 = 32 which is a number in between 30 and 40
So the newspaper has 4 sections.
