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.
A and D
To get x on one side you have to, in this case, add 3 to both sides. This is the addition property of equality
let's recall that a circle has a total of 360°, so a circular clock has 60 minutes, and if we divide those 360° into 60 even intervals, that'd be 360/60 or 6° per minute.
so since 1 minute is 6°, then 23 minutes is just 23 * 6 degrees.
Answer: 30 mph for the rest of the trip
Step-by-step explanation:After 2 hours he drove 110 mph out of 170 mph. Subtract 110 out of 170. Now you have 60. Now divide that by 2 hours to get and answer of 30 mph
I would say "B"
The important part of a budget is knowing where the money is going...sometimes in a budget, people save for financial goals last, because they may think it's less important.
