1/2n + 11
of means multiply and more than is addition
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.
Answer:
Division
Step-by-step explanation:
The order of operations (the simplest version) is...
PEMDAS
P: Parentheses
E: Exponents
M/D: Multiplication/Division (whichever comes first)
A/S: Addition/Subtraction (whichever comes first)
The answer is division, since it comes before addition and subtraction.
