A. The two listed added up will be 180 degrees.

5x - 57 + 3x + 5 = 180

8x - 52 = 180

8x - 52 + 52 = 180 + 52

8x = 232

x = 29

B. The two listed added up will be 180 degrees.

2x + 4x + 150 = 180

6x + 150 = 180

6x + 150 - 150 = 180 - 150

6x = 30

x= 5

Andy had a snowball (a perfect sphere) with a radius of
gtnhenbr [62]

Answer:

The ratio of the current volume to the original one is 2.28

Step-by-step explanation:

Since the radius of the ball increased at a rate of 0.25 cm/s and Andy spent 4 seconds making it bigger, then the ball's radius increased by 4*0.25 = 1 cm. The volume of a sphere is given by:

volume = (4/3)*pi*r³

The original volume of the ball was:

volume1 = (4/3)*3.14*(3)³ = (12.56/3)*27 = 12.56*9 = 113.04 cm³

The final volume of the ball was:

volume2 = (4/3)*3.14*(3 + 1)³ = (12.56/3)*(4)³ = (12.56/3)*64 = 257.95 cm³

The ratio of the current volume of the ball to the original one is:

ratio = volume2/volume1 = 257.95/113.04 = 2.28
