The conversion of square feet to square yards can be represented by direct variation. Three square yards are
grandymaker [24]
<h3>The constant of variation is \frac{1}{9}</h3><h3>The equation is y=\frac{1}{9}x</h3>

<em><u>Solution:</u></em>

Given that,

The conversion of square feet to square yards can be represented by direct variation

Let y represent the number of square yards

Let x be the number of square feet

y \propto x

y = kx ------ eqn 1

Where, "k" is the constant of variation

Three square yards are  equivalent to 27 square feet

Substitute, y = 3 and x = 27 in eqn 1

3 = k \times 27\\\\k = \frac{3}{27}\\\\k = \frac{1}{9}

Thus the constant of variation is \frac{1}{9}

<em><u>What is the equation representing the direct variation?</u></em>

Substitute k = 1/9 in eqn 1

y = \frac{1}{9}x

Thus the equation is found

You can represent the measures of an angle and its complement as x° and (90 − x)°. Similarly, you can represent the measures of
pashok25 [27]

Answer:

120;60

Step-by-step explanation:

The measure of an angle is equal to twice the measure of its supplement.

This means that x = 2(180-x)

<em>Simplify</em>

x = 360 -2x

<em>Isolate the variable</em>

3x = 360

x = 120

This makes its supplement 60

Nimfa-mama [501]

Answer:

36 inches²

Step-by-step explanation:

A=bh where b is the base length and h is the height

The base length of the parallelogram is 12 inches and its height is 3 inches. Plug these values into the equation.

A=(12)(3)\\A=36

Therefore, the area of the figure is 36 inches².

I hope this helps!
