The dashed triangle is a dilation image of the solid triangle with the center at the origin. is the dilation an enlargement or a reduction? find the scale factor of the dilation.

1) it is a reduction

2) the scale factor is 1/ 3

Explanation:

You can use any side or even the height of the triangle to calcualte the scale factor.

Using the horizontal height (that is the height respect the vertical side):

The height of the original triangle (solid lines) is 6 - (-6) = 6 + 6 = 12

The height ot the image (dashed lines) is: 2 - (-2) = 2 + 2 = 4

So, the scale factor is 4 / 12 = 1/3

That is why it is a reduction, because the scale factor is less than 1

Step-by-step explanation:

Its a reduction

Rate 3:1

Step-by-step explanation:

The reduction of that triangle to the dashed one is easy to calculate since the fraction of the side on the right is 1 unit in the dashed triangle and in the large one is three units, so the rate would be 3:1 or 1/3 so with that you can reduce all of the sides of the triangles and you have the reduction of the triangle.

you never say the total so we cant find the percentage used for petrol

step-by-step explanation:

150.6

all i did was i multiplied 5.02 by 30
