8. write three other proportions for each given proportion. 35 miles/2 hours=87.5 miles/5 hours

218.75 miles / 12.5 hours

437.5 miles / 25 hours

656.25 miles / 37.5 hours

Step-by-step explanation:

35 miles / 2 hours = 87.5 miles / 5 hours

This is the  ratio of 2.5. So, the other proportions are

87.5 x 2.5 miles / 5 x 2.5 hours = 218.75 miles / 12.5 hours

87.5 x 5 miles / 5 x 5 hours = 437.5 miles / 25 hours

87.5 x 7.5 miles / 5 x 7.5 hours = 656.25 miles / 37.5 hours

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
