Three co-workers are packing books in a storage bin. The bin is 4 feet high, 9 feet long, and 11 feet wide. If 6 books fill 1 cu
2 answers:
Alright, lets get started.
Height of the bin = 4 ft
Length of the bin = 9 ft
Width of the bin = 11 ft
Volume of the bin =
Volume V
Volume V cubic feet
6 books fiils 1 cubic feet
or
1 cubic feet is filled by = 6 books
So, 396 cubic feet is filles by
So, 396 cubic feet is filles by books
It means 2376 books will fit in the storage bin. : Answer
Hope it will help :)

Answer:
The angle of elevation to the top of the building is 63.61 degrees
Step-by-step explanation:
Here, we want to calculate angle of elevation to the top of the building.
For this, we need a triangle
Please check for this in the attachment.
From the diagram, we are to calculate the angle theta.
To do this, we use trigonometric identities.
Looking at what we have, we have the hypotenuse and the adjacent.
So the trigonometric identity to use is the cosine
Mathematically Cosine theta = adjacent/hypotenuse
Thus, Cos theta = 20/45
Cos theta = 0.444444444444444
Theta = Arc cos(0.444444444444444)
Theta = 63.61 degrees
