Answer:
18ft wide and 33 ft long
Step-by-step explanation:
We are told in the question that:
Cynthia Besch wants to buy a rug for a room that is 20 ft wide and 35 ft long.
The Area of the carpeting she must have = 594 ft²
To solve for this, we have:
Length × Width = Area of a rectangle
594ft² = Length × Width
594ft² = (20 - x) (35 - x)
594 = 700 - 20x - 35x + x²
594 = 700 - 55x + x²
Collect like terms
x² - 55x + 700 - 594
x² - 55x + 106
We factorise
x² - 2x - 53x + 106
(x² - 2x) -(53x + 106)
x(x - 2) -53(x - 2)
(x - 2)(x - 53)
x - 2 = 0, x = 2
x - 53 = 0, x = 53
We choose the least value for x
Hence, x = 2
Length = 20 - 2 = 18ft
Width = 35 - 2 = 33ft
The dimensions the rug should have is 18ft by 33ft, meaning 18ft wide and 33 ft long
Hello There!
The volume for a cylinder is Pi*r^2*h
We are going to leave our Answer in terms of pi so first we need to square our radius which we know is 5
Our radius is 25 because we squared 5. Next, we need to multiply 25 by our height which is 11.
25 multiplied by 11 is 275 so our Answer would be 275
-72 just do 8*9 and add a negative sign
Answer:
3 meters
Step-by-step explanation:
Square root of 9 is 3 (3x3 = 9) so if all the sides are the same, they must all be 3 meters
5% * $6300/100% = $315
$315 * 5=$1575
