Mathematics

Bumek [7]2 years ago

The scale factor of the given dilation is 3.

Step-by-step explanation:

Step 1:

In order to determine the scale factor, we divide the measurement after scaling by the same measurement before scaling.

In the given graph, the preimage has a length of 3 units while the image has a length of 9 units.

Step 2:

So here the measurement after scaling is the length of the image which is 9 units and the measurement before scaling is the preimages length of 3 units.

The scale factor =\frac{9}{3} = 3.

So the scale factor is the third option 3.

28 is 35% of what number?
Fofino [41]
28 is 35% of 80

Convert the percentage (35) into a decimal by dividing it over 100:
\frac{35}{100} = 0.35

Divide 28 over 0.35:
\frac{28}{0.35} = 80
