The dashed triangle is the image of the solid triangle. the center of dilation is (6, 6) . what is the scale factor used to create the dilation? enter your answer as an integer or decimal in the box.

Scale factor = -0.2

Step-by-step explanation:

In the picture attached,

Big (with solid lines) triangle has been dilated to form a new (small in dashed lines).Center of dilation is (6, 6).

Solid line of the bigger triangle has the vertices as (-9, 6) and (6, 6)

So the measure of this leg =

l = 15

corresponding side of the dashed triangle has the vertices (6, 6) and (9, 6)

Measure of this side =

l' =

l' = 3

Scale factor =

                    = 0.2

Since the bigger triangle has been inverted so the sign of the scale factor will be negative.

Therefore, the scale factor by which the bigger triangle has been dilated is -0.2

518,400

step-by-step explanation:

the area is multiplying all the given measurements together.

40 * 18 * 30 * 24 = 518,400

$9.89

step-by-step explanation:

9.90 = p x .06 x .25 (3/12 changed to a decimal)

9.90 = p x 0.015

9.90 - 0.015 = p

9.89 = p
