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:
V = 10x 4x 12
I think that's the answer :)
Answer:
493.2 · 10⁸
Step-by-step explanation:
1 person = 180 bars
274,000,000 people · 180 bars per person
274,000,000 can be simplified to 274 · 10⁶
274 · 180 = 49320 · 10⁶
Now transferring this to scientific notation by moving the decimal two spaces to the left
493.2 · 10⁶ + 10² The 10² is for the two spaces to the left
493.2 · 10⁸
