Answer:
![\frac{75}{no. of employee} - 5](https://tex.z-dn.net/?f=%5Cfrac%7B75%7D%7Bno.%20of%20employee%7D%20%20-%205)
Step-by-step explanation:
Total we have: 3000
Number of employees = x
Number of hours = y
The equation is:
3000 = (200 + 40y)x
We need to solve for y:
3000/x = 200 +40y
40y = 3000/x -200
![y=\frac{75}{x} - 5](https://tex.z-dn.net/?f=y%3D%5Cfrac%7B75%7D%7Bx%7D%20-%205)
Therefore, no. of hours = ![\frac{75}{no. of employee} - 5](https://tex.z-dn.net/?f=%5Cfrac%7B75%7D%7Bno.%20of%20employee%7D%20%20-%205)
The common denominator is 20.

Answer:
A
Step-by-step explanation:
Using Pythagoras' identity in the right triangle.
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is
BC² = 9² + 12² = 81 + 144 = 225 ( take the square root of both sides )
BC =
= 15 → A
The expression that represents the surface area of the square based pyramid is 36 + 15 + 15 + 15 + 15
<h3 />
<h3>How to find the surface area of a square based pyramid?</h3>
The surface area of the pyramid is the sum of the area of the whole faces of the pyramid.
Therefore, the pyramid has 4 triangular faces and 1 square faces.
Therefore,
surface area of the pyramid = area of the square + 4(area of the triangle)
area of the square = 6² = 36
area of each triangular faces = 1 / 2 bh
where
Therefore,
area of each triangular faces = 1 / 2 × 6 × 5 = 30 / 2 = 15
Hence, the expression is as follows:
surface area of the pyramid = 36 + 15 + 15 + 15 + 15
