a student has to buy graph paper and printer paper. The graph paper x cost $2, while the printer paper, y costs $3. She wants to buy at least 7 packs of paper but wants to spend at most $21. Enter a system of inequalities for the given situation and select the graph of the system

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

question 1: step-by-step explanation:

1/4 of 84 = 84÷4= 21
