Answer:
The scale factor is k = 1/30
a)
<u>The length of the wing on the model:</u>
- 9 m * 1/30 = 900 cm * 1/30 = 30 cm
b)
<u>The area of the tail section of the plane:</u>
- 80 cm² : (1/30)² =
- 80 cm² * 900 =
- 72000 cm² =
- 72000 * (1/100)² m² =
- 7.2 m²
It is 5.5! Because she runs 10 miles every 2 hours.
The answer is D
-12+11=-1
-1+11=10
10+11=21
