Answer:
Below.
Step-by-step explanation:
12. That is a semicircle
The central angle is 180 degrees.
1. 13
2. 20
3. 4
4. 40
5. 4
6. 4
The thousandth place is the 3rd digit after the decimal.
So your answer is 93.013
I think the answer is c.......
Perimeter: P=24 ft
Lenght: L
Width: W
The length is 2 ft longer than the width:
(1) L= W+2 ft
Perimeter: P=2(W+L)
P=24 ft
2(W+L)=24 ft
Dividing both sides of the equation by 2:
2(W+L)/2 =(24 ft)/2
(2) W+L=12 ft
We have a system of 2 equations and 2 unkowns:
(1) L=W+2
(2) W+L=12
Using the method of substitution: Replacing L by W+2 in the second equation:
(2) W+L=12
W+(W+2)=12
W+W+2=12
2W+2=12
Solving foe W
2W+2-2=12-2
2W=10
Dividing both sides of the equation by 2:
2W/2=10/2
W=5
Replacing W by 5 in the first equation:
(1) L=W+2
L=5+2
L=7
Answers:
What is the width? 5 ft
