Answer: <em>Constant of proportionality is the constant value of the ratio between two proportional quantities. Two varying quantities are said to be in a relation of proportionality when, either their ratio or their product yields a constant.</em>
Step-by-step explanation:
To find the constant of proportionality, we use the formula k=y/x. So we have k=20/500 = 0.04.
The equation representing this situation will look like y=kx. Substituting in our value of k that we found, we have the equation y=0.04x.
We can use our equation to find the answer to this problem.
The statement that must be true about square WXYZ are as follows;
- WX ≅ XY
- WX ≅ YZ
- ∠W is a right angle.
<h3>Properties of a Square.</h3>
- All sides are equal to each other.
- Opposite sides are parallel to each other.
- All the angles are right angle.
- The diagonals bisect each other and are perpendicular.
Therefore, the statement that must be true about square WXYZ are as follows;
- WX ≅ XY
- WX ≅ YZ
- ∠W is a right angle.

Answer:
Amount of paint to be bought = 10 gallons
Step-by-step explanation:
Amount of paint needed by Mrs. Sullivan to paint her house = 12 gallons
She is already having paint = 8 quarts
Since, 1 quart = 0.25 gallons
Therefore, 8 quarts = 8 × 0.25
= 2 gallons
So, amount of paint she is already having = 2 gallons
Amount of paint to be bought = 12 - 2
= 10 gallons
In 2009 the company made thirty-eight million five hundred thousand dollars
