Answer:
10
Step-by-step explanation:
We want to find k when y=kx
2y = 20x
Divide each side by 2
2y/2 =20x/2
y = 10x
The constant of proportionality is 10
Answer: A
Step-by-step explanation:
- Open circle means that x does not equal that number. For example, the open circle on C is on 8, so that shows x is not equal to 8.
- Closed circle means that x does equal that number. For example on A, there is a closed circle on 8, so x could equal 8.
First, we need to solve the equation.
- Subtract 200 frim 1200 -> 125x ≥ 1000.
- Divide 125 from 1000 to isolate the x -> x ≥ 8
So, that means x is bigger than or equal to 8.
The perimeter is 20 units
Step-by-step explanation:
The end-point of a side of square can be used to calculate length of a side. And the side will be used to calculate the perimeter.
Given
(3,-1) and (7,2)
Let
(3,-1) = (x1,y1)
(7,2) = (x2,y2)
We have to calculate the distance
The formula for distance is:

Let s be the side of a square
then,

The side of square is 5 units. Then,

The perimeter is 20 units

Answer:
There is no correct answer. Volume = length x width x height.
Step-by-step explanation:
14 x 4 x 9 = 504. I would pick C. 144in ^3 because it's closest to 504 but I'm not sure.
