First do 3x3, which is 6.
Then do 1/2 x 1/2. Convert the 1/2's to .50's
Do .50 x .50. Start with 5 x 5, and get 25. Then move decimal 2 places over.
Now that you have 6 and .25, add them and get 6.25.
.25 as a fraction is, of course, 1/4
Your final answer should be 6 1/4
The answer would be 5x+5y
Answer:
Step-by-step explanation:
The 1 choice. The events are independent because P(red) ×P(green)= P(red and green)
Answer: 9
Step-by-step explanation:
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
