Answer:
Length = 20feet
Width = 10feet
Step-by-step explanation:
Area of a rectangle = LW
Perimeter P= 2(L+W)
L is the length
W is the width
If the length of a rectangle is twice as long as the width, then;
L = 2W
Substitute into the foemula
A = (2W)W
A= 2W²
If the area is 200ft², then;
200 = 2W²
100 = W²
W = √100
W = 10ft
Since L = 2W
L = 2(10)
L = 20ft
Hence the length of the rectangle is 20feet and the Width is 10feet
The answer is 5 because 5 is a factor of 15 but not a multiple of 5
Answer:
50%
Step-by-step explanation:
Each coin has 2 sides. There is a 100% chance you will flip the coin, and since there are two sides, you have to divide 100 by 2.
50%
Answer:
2 and 11
Step-by-step explanation:
Let's start by calling these two numbers x and y. Now, you can set up the following system of equations:
x*y=22
x+y=13
You can rearrange the following equation to be x=13-y, and substitute into the first.
(13-y)*y=22
-y^2+13y=22
y^2-13y+22=0
y=2 or 11
x=11 or 2

Answer:
$1,142.25
Step-by-step explanation:
Gross = $1500
Deductions = 6.2% + 1.45% + 16.2% = 23.85%
100% - 23.85% = 76.15%
100% = 1500
76.15$ = x
By cross multiplication
100x = 1500 * 76.15
x = $1,142.25
