Select the three ratios that represent the number of red cars to blue cars.
Lorico [155]

Three ratios that represent the number of red cars to blue cars are

2 : 3

6 : 9

8 : 12

\texttt{ }

<h3>Further explanation</h3>

<u>Given:</u>

Number of Red Cars = 4

Number of Blue Cars = 6

<u>Asked:</u>

Ratio = ?

<u>Solution:</u>

<em>Let:</em>

<em>Number of Red Cars = R</em>

<em>Number of Blue Cars = B</em>

The ratio that represent the number of red cars to blue cars is :

R : B = 4 : 6

We can find other ratio by dividing or multiplying the above comparison with the same number :

R : B = (4/2) : (6/2) = 2 : 3

R : B = (4 \times 2) : (6 \times 2) = 8 : 12

R : B = (4 \times \frac{3}{2}) : (6 \times \frac{3}{2}) = 6 : 9

\texttt{ }

<h3>Conclusion:</h3>

Three ratios that represent the number of red cars to blue cars are:

  • 2 : 3
  • 6 : 9
  • 8 : 12

Triangle XYZ is shown on the coordinate plane below:
Ivanshal [37]
The line y=1 is the horizontal line passing through the point (0, 1). We have drawn it with red.

The reflection across this line of each point X, Y, and Z is such that the distance of each  X, Y, and Z is equal to the distance of each X', Y', and Z', respectively, to the red line.

According to our drawing, we see that the coordinates of X' are (3, 3).

Answer: a.
