Ecan anyone help me? In your class, you have scores of70,66,85 and 87and on the first four of five tests. To get a grade of c , the average of the first five tests scores must be greater than or equal to70 and less than80 .
a.
Solve an inequality to find the least score you can get on the last test and still earn a c .
b.
What score do you need if the fifth test counts as two tests?

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

the first option is the answer.

answer: c. is your answer
