Took the test

Answer 2

Answer:

Three-tenths

Step-by-step explanation:

Dilation is a technique which is used to make the objects larger or smaller. This transformation is an image that is the same as the original shape that is the image is similar to the transformation.

Here, we are given that triangle D E F is dilated to create smaller triangle D' E' F' .

Also, the length of O F' =  3 and the length of F'F = 7.

The scale factor of dilation means the ratio by which each side of the figure or an object is being dilated.

The scale factor will be:

OF' / OF = 3 / 10.

Therefore, the correct option is option (A) Three - tenths.
