A spherical exercise ball has a maximum diameter of 30 inches when filled with air. The ball was completely empty at the start, and an electric air pump is filling it with air at the rate of 1600 cubic Inches per minute.
The formula for the volume of a sphere is 41
Part A
Enter an equation for the amount of air still needed to fill the ball to its maximum volume, y, with respect to the
number of minutes the pump has been pumping air into the ball, X.
Part B
Enter the total amount of air, in cubic inches, still needed to fill the ball after the pump has been running for 4
minutes.
Part C
Enter the estimated number of minutes it takes to pump up the ball to its maximum volume.
Part A

x ≥ 18 is your answer

step-by-step explanation:

let "a number" = x

(2/3)x + 17 ≥ 29

isolate the variable (x). do the opposite of pemdas (parenthesis, exponent (& root), multiplication, division, addition, subtraction).

first, subtract 17 from both sides.

(2/3)x + 17 (-17) ≥ 29 (-17)

(2/3)x ≥ 29 - 17

(2/3)x ≥ 12

next, multiply 3/2 to both sides to isolate the x

(3/2)(2/3)x ≥ 12(3/2)

x ≥ 12(3/2)

simplify. multiply, then divide

x ≥ (12 * 3)/2

x ≥ (36)/2

x ≥ 18

x ≥ 18 is your answer

the arc length is found by finding the circumference of the full circle (2xpixradius) and then dividing by 4 to find just one quarter of the circle (90 degrees).

answer: i think you should do the math and pay attention in class : )

that is truly what   think but if i get the answer i will
