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.
Answer:
Im guessing you meant it takes 1/3 cups of flour to make 1/4 of a cake not "14"
Step-by-step explanation:
in that case you would do
1/3+1/3+1/3+1/3
or 1/3*4
which would be 4/3
or
1 1/3
Answer:
Scale factor = 
Step-by-step explanation:
Perimeter of the actual flag = 22 in.
Perimeter of the scale drawing of the flag = 11 in.
Since, perimeter of a triangle = Sum of all three sides of the given triangle
Therefore, scale factor of the drawing
= 
= 
= 
=
Therefore, scale factor of the drawing will be .
Each side of the scaled triangle will be half of the actual triangle.
Answer:
The answer is 70.8
Step-by-step explanation:
You do 7x3 times 2 and then 3x2.6 and then 7x3 again. You add them all up and get 70.8
21 + 21 + 3.9 + 3.9 + 21 = 70.8
