Answer:
8 Shampoo Concentrate
Step-by-step explanation:
There's a ratio of 9:2 so for every 9 cups of water there's two cups of shampoo concrete.

Answer:
The answer to your question is d = 3683.5 ft
Step-by-step explanation:
Data
Altitude = a = 30,Ф000 ft
angle = Ф = 7°
distance = d = ?
Process
To solve this problem we must use trigonometric functions. The trigonometric function that relates the Opposite side and the adjacent side is the tangent.
tan Ф = Opposite site / Adjacent side
-Solve for Opposite side (d)
Opposite side = Adjacent side x tan Ф
- Substitution
d = 30000 tan 7
-Simplification
d = 30000(0.1228)
-Result
d = 3683.5 ft
-Conclusion
The plane must begin to descent 3683.5 ft before the airport.
