2l + 2w = P
l = 35, P = 84, w=?
2*35 + 2*w = 84
70 + 2w = 84
2w = 84 - 70
2w = 14
w = 14/2
w = 7 in
Answer:
The answer is 3418.1 ft rounded to the nearest tenth.
Step-by-step explanation:
The total volume of the cylinder can be defined by the Area of circular base * Perpendicular height.
The area of the circular base can be calculated as
![\pi \times {r}^{2}](https://tex.z-dn.net/?f=%5Cpi%20%5Ctimes%20%20%7Br%7D%5E%7B2%7D%20)
where r is the radius of the circular base, which is 8 ft.
The area of the circular base is
![\pi \times {8}^{2} = 64\pi](https://tex.z-dn.net/?f=%5Cpi%20%5Ctimes%20%20%7B8%7D%5E%7B2%7D%20%20%3D%2064%5Cpi)
We also know the height of the cylinder is 17 ft.
Hence, the volume of the cylinder is
![64\pi \times 17 = 1088\pi = 3418.0528...](https://tex.z-dn.net/?f=64%5Cpi%20%5Ctimes%2017%20%3D%201088%5Cpi%20%3D%203418.0528...)
This will be rounded up to 3418.1 with the nearest tenth

Answer:
Step-by-step explanation:
Given that a random sample of records of home sales from Feb. 15 to Apr. 30, 1993, from the files maintained by the Albuquerque Board of Realtors gives the Price and Size (in square feet) of 117 homes.
A regression is done to predict Price (in thousands of dollars) from Size
Hence
a)we have size as independent variable and price as dependent variable. Units for size are square feet and price are in 1000s of dollars.
b) Slope will have unit has 1000dollar/sqft
c) Slope is positive since price is directly variant over size.
So slope will be positive.
Simplifying rational expressions will make the further calculations easier since the variables to work with will usually be smaller.
To determine that a rational expression is in simplest form we need to make sure that the numerator and the denominator have no common variables.
