Bob is building a wooden cabin. The cabin is 303030 meters wide. He obtained a bunch of 171717 meters long wooden beams for the
roof of the cabin. Naturally, he wants to place the roof beams in such an angle that each pair of opposite beams would meet exactly in the middle. What is the angle of elevation, in degrees, of the roof beams
1 answer:
Answer:
Step-by-step explanation:
Alright, lets get started.
Please refer the diagram I have attached.
The width of the room is 30 meters.
If two beams will be making an angle, they will half the width.
There will be a right triangle made, so using SOH CAH TOA,
taking cos inverse
x =
x = 28.07° : Answer
Hope it will help :)

Answer:
The number of small mowers are 19 and the large mowers are 11.
Step-by-step explanation:
Given:
A garden supply store sells two types of lawn mowers. Total sales of mowers for the year were $8379.70. The total number of mowers sold the 30. The small mower cost $249.99 and the large mower costs $329.99.
Now, to find the number of each type of mower sold.
Let the number of small mower be
And the number of large mower be
So, total number of mowers are:
Now, the total sales of mowers are:
Substituting the value of from equation (1) we get:
<em>Subtracting both sides by 7499.7 we get:</em>
<em>Dividing both sides by 80 we get:</em>
The number of large mower = 11.
Now, to get the number of small mowers we substitute the value of in equation ( 1 ):
The number of small mower = 19.
Therefore, the number of small mowers are 19 and the large mowers are 11.
Answer:
The probability that a fish caught by a fisherman is between 0.25 feet and 2 feet long is 0.4375.
Step-by-step explanation:
The probability density function or p.d.f. for the length <em>x,</em> in feet, of some type of fish caught by sport fishermen is :
The probability that a fish caught by a fisherman is between 0.25 feet and 2 feet long is:
Thus, the probability that a fish caught by a fisherman is between 0.25 feet and 2 feet long is 0.4375.
