Answer:
4(x-5)=92
4x-20=92
4x=92+20 (as we shifted - 20 to other side, it becomes +)
4x=112
x=112/4
x=28
Therefore the x=28
Answer:
40% or 0.4
Step-by-step explanation:
70 ÷ 175 = 0.4
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
