Select the two figures that are similar to the 9 by 6 figure that’s is shown.
Eduardwww [97]

Answer:

The correct option is 3. The green figure is similar to the 9 by 6 figure.

Step-by-step explanation:

Let a small square represents 1 unit.

From the given figure it is noticed that

1. The dimensions of red figure is 4 by 3.

2.The dimensions of brown figure is 4 by 6.

3.The dimensions of green figure is 2 by 3.

3.The dimensions of purple figure is 3 by 6.

The dimensions of given figure is 9 by 6. The proportion of its dimensions is

\frac{9}{6}=\frac{3}{2}

The corresponding sides of two similar figure are proportional. It means the ration of sides must be \frac{3}{2}.

The dimensions of green figure is 2 by 3. It means the proportion of its dimensions is \frac{3}{2}.

Therefore the correct option is 3. The green figure is similar to the 9 by 6 figure.

Aleksandr [31]
Given that t<span>he x-axis represented the number of small tanks and the y-axis represented the number of large tanks.

Given that </span>h<span>is small tanks would require 2 oz of conditioner and his large tanks would require 6 oz of conditioner and there are a total of 72 oz of water conditioners available.

The line representing the various combinations of </span>tanks he could put the water conditioner into is given by 2x + 6y = 72.

Since, t<span>he manager labeled only the intercepts.

The x-intercept is the value of x when y = 0 and is given by

2x + 6(0) = 72

x = 72 / 2 = 36

Thus, the x-intercept is (36, 0)

</span>
<span>The y-intercept is the value of y when x = 0 and is given by

2(0) + 6y = 72

y = 72 / 6 = 12

Thus, the x-intercept is (0, 12)

Therefore, the points labeled by the manager are: (0, 12) and (36, 0)
