Given:
- Surface area of cube = 150 ft²
To Find:
Solution:
As here in Question we are given Surface area of cube is 150 sq. feet. So, firstly we have find the side of edge of cube. Let 'a' be the edge of the cube
We know that,
Substituting the required values,
- Edge of the cube is 5 feet
Now,
Hence,
- Volume of the cube is 125 cu. feet
Answer:
1) There were 120 customers per night when the restaurant opened
2) y = -2x + 24
Step-by-step explanation:
1) x represents the # of months since a restaurant opened, and y represents the average number of nightly customers.
y=mx+b
120 is <em>b</em> in this situation, which is the y-intercept of the line. This means that 120 is the starting number of customers when the restaurant first opened.
We know that the true value for pi is given as 3.14156.
Now, we have been given that the approximate value for pi is 3.141
We know the formula
Absolute error, 
Relative error is given by
![\text{Relative error }= \frac{\Delta x}{\text{true value} }\\ \\ \text{Relative error }=\frac{0.00056}{3.14156} \\ \\ [tex]\text{Relative error }=0.000178](https://tex.z-dn.net/?f=%5Ctext%7BRelative%20error%20%7D%3D%20%5Cfrac%7B%5CDelta%20x%7D%7B%5Ctext%7Btrue%20value%7D%20%7D%5C%5C%0A%5C%5C%0A%5Ctext%7BRelative%20error%20%7D%3D%5Cfrac%7B0.00056%7D%7B3.14156%7D%20%5C%5C%0A%5C%5C%0A%5Btex%5D%5Ctext%7BRelative%20error%20%7D%3D0.000178)
