Emma and Kelton are running a (26.2) mile marathon. Emma has run 19.65 miles so far, while Kelton has run 13.1 miles. What percentage of Emma's distance has Kelton completed.

66.67%

Step-by-step explanation:

The distance Emma has run is 19.65 miles.

The distance Kelton has run is13.1 miles.

We want to express 13.1 miles as a percentage of 19.65 miles.

The quantity that comes after 'of' becones the base or denominator.

Multiply by 100 by moving the decimals forward twice.

Therefore Kelton has covered 66.67% of Emma's distance.

d 25 pi/6

step-by-step explanation:

the diameter is 10 inches

the radius is 1/2 of the diameter or 5 inches

the area of the circle is

a = pi r^2

  = pi 5^2

  = 25 pi

the slice is 60 degrees of the entire circle.

60 degrees out of 360   60/360 = 1/6

the area of the slice is 1/6 of the circle

a slice = 1/6 a circle

a slice = 1/6 * 25 pi
