Answer:
16%
Step-by-step explanation:
because 50 is 16% of 800
hope that helps and is correct
Answer: D
Explanation:
Point slope form:
(y - y1) = m(x - x1)
Coordinate given = (2,-6)
Slope = 3/5
Thus:
(y -(-6)) = 3/5(x - 2)
y + 6 = 3/5(x - 2)
You can use the sin function to solve this.
Think of a triangle with the conveyor being the longest side (hypotenuse). The height (the vertical side) is H=17m. The angle of elevation is a=36.2. We are looking for length of the hypotenuse, L.
The sin is the ratio of height to hypotenuse: sin(36.2) = H/L = 17/L
Now solve for L:
L = 17/sin(36.2) = 17m/0.59 = 28.78m
The conveyor needs to be approx. 28.8m long to get close to the max. efficient angle.
