The number is made 1,000 times greater and so the units must be made 1,000 times smaller. The answer is "A" milligrams.
The answer is most likely c
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 
So the scale factor is the third option 3.
The measure of QR is 6 units, which is 6 meters, since every unit on the coordinate grid is 1 meter.
The measure of UT is also 6 meters.
The measure of QU is 8 meters.
To find the measure of RS, we use the distance formula:

We substitute the coordinates of R and S into the formula and have:

To find the measure of ST we use the distance formula again, substituting the coordinates for S and T into the formula:

Now we find our perimeter by adding the sides together: 5.39 + 3.61 + 6 + 6 + 8 = 29 meters
Since fencing costs $24.75 per meter, we multiply this by our perimeter:
29(24.75) = $717.75
