Answer: 
Step-by-step explanation:
Given, A pizza is to be cut into halves.
Since half is represented by 
.
So each piece is now of the original.
if each of these halves is to be cut into sevenths, then the fraction of final pieces would be: 
or we can say each half is divides into 7 pieces since there are two halves, so there will be 2 x 7 = 14 peices.
And the fraction of the pizza is each of the final pieces = .

<span>πd is the circumference of a circle, so with a diameter of 4 a single circle has a circumference of 4π. 1/3 of each circle is in contact with the belt, so that total part is still 4π. Then, the part of the belt connecting from tangent to tangent is 2 radii, so 3 areas is 12. The belt would then be 12+4π cm.</span>
Answer:
11° and 79°
Step-by-step explanation:
Complementary angles sum to 90°
let x be one angle then the other angle = x + 68 , hence
x + x + 68 = 90
2x + 68 = 90 ( subtract 68 from both sides )
2x = 22 ( divide both sides by 2 )
x = 11
The 2 angles are x = 11° and x + 68 = 11 + 68 = 79°
As a check : 11 + 79 = 90
