Before we solve, let's define what a scale factor is. A scale factor is a certain number that can be multiplied or divided by to get a smaller or bigger image that's similar to the current image.
We have 48 by 36 as our original.
It has been reduced to an 8 by 6.
This means we must divide.
Before we get into any complicated ideas, if any, let's try a simple trick.
Divide 48 by 8 and 36 by 6. This should give us a scale factor if they give us the same quotients.
48 / 8 = 6
36 / 6 = 6
It turns out our scale factor is 1/6 (the same as dividing by 6).
The answer cannot be 1/8 because 36 / 8 doesn't give us 8 as a quotient.
The answer also cannot be 6 because we'd have to mutliply our current sides by 6 to get the new image, which it was the opposite.
By elimination and work shown, A.) 1/6 is the correct answer.

There are 3 feet in 1 yard, so 90/3 = x cubic yards
x = 30
30 cubic yards is your answer

Answer:
252
Step-by-step explanation:
When it comes to perimeter, the ratio is the same. So, the scale factor of the perimeters in this problem is simply, 3.5. To find the new perimeter, multiply 3.5 by 72 to get 252. :)
