Morning:
3 pints every 7 minute = 3/7 pints/minute = 0.429 pints/minute
Afternoon:
2 pints every 5 minutes = 2/5 pints/minute = 0.4 pints/minute
Difference:
3/7 - 2/5 = 15/35 - 14/35 = 1/35 pints/minute
0.429 - 0.4 = 0.029 pints/minute
Answer:
The answer to your question is: letter a
Step-by-step explanation:
data
balls diameter = 0.75 in then radius = 0.375 in
rectangular prism = length = 3 in width = 3 height = 7.5 in
Formula
Rectangular prism volume = l x w x h = 3 x 3 x 7.7 = 67.5 in³
ball volume = 4/3 (3.1416)(r³) = 4/3 (3.1416)(0.375)³ = 0.220in³
but 0.220in³ ------------------- 100 %
x ------------------- 190%
x = 0.418 in³
Finally divide the rectangular prism volume by ball volume
# of balls = 67.5 / 0.418 = 161.4 ≈ 160
