What is the scale factor in the dilation ?<br><br>1/6<br><br>1/3<br><br>3<br><br>6​
anzhelika [568]

Answer:

3

Step-by-step explanation:

<u>1) Find two corresponding lengths between the image and the pre-image</u>

Pre-image (bottom side) = 3 units

Image (bottom side) = 9 units

We can use any corresponding lengths for this step.

<u>2) Divide the length of the side from the image by the length of the side from the pre-image</u>

9 units ÷ 3 units

= 3

Therefore, the scale factor of the dilation is 3.

I hope this helps!

49 is 35% of what number?
NNADVOKAT [17]
We write this like this:

49=35%x

and we want to find the x.

let's invert the sides:

35%x=49.


35 is equal to 0.35

0.35*x=49

and now we only divide both sides by 0.35:

x=140

so the answer is 140.

(aternatively we can do it through fractions:

35/100*x=49
divide both sides by 7:

5/100*x=7

simplify the first fraction
1/20*x=7

and multiply by 20:

x=140
