Answer:
33 material
Step-by-step explanation:
A simple proportions problem.
9:3 = 3:1
so it takes 3 yards to make 1 window
We multiply both sides by 11 to get
33:11 which now we get 33 material
Answer:
C. Amplitude = 3 feet; period = 8 hours; midline: y = 4
Step-by-step explanation:
The midline is halfway between the lowest point and the highest point.
y = (1 + 7) / 2
y = 4
The period is the time it takes for a full cycle. So the period is 8 hours.
The amplitude is the distance from the midline to the lowest or highest point.
a = 4 − 1 = 3, or a = 7 − 4 = 3
It's also half the distance between the lowest and highest points.
a = (7 − 1) / 2
a = 3
They way to find the y-intercept from two points is to first find the slope, which can be derived from the formula 
.
Then, you can plug in one of the two points 
or 
into the formula y=mx+b to solve for b, which is your y-intercept.
Answer:
w= 12
Step-by-step explanation:
2w=24
divide both sides by 2
2w÷2. 24÷2
2w÷2 cancels each other so solve 24÷2
w= 12
