He will save one year of interest which is $1026.00
After, thorough research I believe that there are 265 pine trees and 0 elm trees since decidous and semi-decidous do not grow near conifers.
Assuming simple interest,
.. i = Prt = $14,300×7.5%×4 = $4,290
Let
l-------> the slant height of the right pyramid
b------> the length side of the square base of the right pyramid
h------> the height of the right pyramid
we know that
Applying the Pythagorean Theorem
![l^{2} =h^{2}+(\frac{b}{2})^{2}](https://tex.z-dn.net/?f=l%5E%7B2%7D%20%3Dh%5E%7B2%7D%2B%28%5Cfrac%7Bb%7D%7B2%7D%29%5E%7B2%7D)
Solve for h
![h^{2}=l^{2}-(\frac{b}{2})^{2}](https://tex.z-dn.net/?f=h%5E%7B2%7D%3Dl%5E%7B2%7D-%28%5Cfrac%7Bb%7D%7B2%7D%29%5E%7B2%7D)
in this problem we have
![l=20\ ft\\\frac{b}{2} =\frac{24}{2} =12\ ft](https://tex.z-dn.net/?f=l%3D20%5C%20ft%5C%5C%5Cfrac%7Bb%7D%7B2%7D%20%3D%5Cfrac%7B24%7D%7B2%7D%20%3D12%5C%20ft)
Substitute in the formula
![h^{2}=20^{2}-12^{2}](https://tex.z-dn.net/?f=h%5E%7B2%7D%3D20%5E%7B2%7D-12%5E%7B2%7D)
![h^{2}=256](https://tex.z-dn.net/?f=h%5E%7B2%7D%3D256)
![h=16\ ft](https://tex.z-dn.net/?f=h%3D16%5C%20ft)
therefore
<u>the answer is</u>
The height of the right pyramid is ![16\ ft](https://tex.z-dn.net/?f=16%5C%20ft)
Answer:
180 because fifty is half of a whole so 90*2=180
