Answer:
Step-by-step explanation:
Let the speed of plane is p and speed of the wind is w.
<u>Then we have:</u>
- 10*(p + w) = 1120 ⇒ p + w = 112
- 20*(p - w) = 1120 ⇒ p - w = 56
<u>Sum the two equations and solve for p:</u>
- p + w + p - w = 112 + 56
- 2p = 168
- p = 84
<u>Find w:</u>
- 84 + w = 112
- w = 112 - 84
- w = 28
Answer:
The answer to your question is 732 in³
Step-by-step explanation:
Data
Rectangular prism layers
Base layer = 12 in x 10 in x 4 in
Second layer = 3 in smaller x 4 in
Volume = ?
Formula
Total volume = Volume of the base layer + Volume of the second layer
Total volume = length 1 x width 1 x height + length 2 x width 2 x height
Substitution
Total volume = 12 x 10 x 4 + (12 - 3)(10 - 3)(4)
Simplification
Total volume = 480 + (9)(7)(4)
Total volume = 480 + 252
Result
Total volume = 732 in³
