A mountain railway AB is of length 864m and rises at an angle of 120° to the horizontal.

Ainat [17]

Answer:

The height above sea level at B is approximately 1,604.25 m

Step-by-step explanation:

The given length of the mountain railway, AB = 864 m

The angle at which the railway rises to the horizontal, θ = 120°

The elevation of the train above sea level at A, h₁ = 856 m

The height above sea level of the train when it reaches B, h₂, is found as follows;

Change in height across the railway, Δh = AB × sin(θ)

∴ Δh = 864 m × sin(120°) ≈ 748.25 m

Δh = h₂ - h₁

h₂ = Δh + h₁

∴ h₂ ≈ 856 m + 748.25 m = 1,604.25 m

The height above sea level of the train when it reaches B ≈ 1,604.25 m

NUMBER 27 please!!!!!!!

The inequality can be:
$150x \leqslant 3000$
Now you divide both sides by 150 to get the #of boxes.

$3000 \div 150$
Lastly, x is 20. So the maximum amount of boxes that the freight elevator can hold is 20
