Answer:
60
Step-by-step explanation:
let a = 22 / kg, and b = 12 / kg
a + b = 20 kg
22a + 12b = 15 * 20
12a + 12b = 240
10a = 60
Answer:
All of them are required for that equation because that is the Standard form equation

I don’t see a picture can you tell me and maybe I can help
Answer:
Explanation:
The figure attached shows sketches the situation described.
You have two right triangles.
For the right triangle with the plane on the position A, you can write:
⇒ H = (800 + x) tan(20º)
For the right triangle with the plane on the position B, you can write:
⇒ H = x tan(21.4º)
To solve, equal both equations:
- x tan(21.4º) = (800 + x) tan(20º)
- x tan(21.4º) = 800 tan(20º) + x tan(20º)
- x = 800 tan(20º) / ( tan(21.4º) - tan(20º) )
Substitute in the equation H = x tan(21.4º)
- H = 10,426.899856 × tan(21.4º) = 4,086 ft
Rounding to one signficant figure that is 4,000 ft.
