Answer:
1) 10
2) 4.5
3) 28 ft
4) 240 in.
5) 8 in.
Step-by-step explanation:
For the first question, you know one of the pairs of sides, 6 and 9. This ratio stays the same, so 6/9=z/15 and z = 10.
For the 2nd question, do the same with the 8 and 6. 6/8=y/6, so y = 36/8 or 9/2 or 4.5.
For the 3rd question, call the longer side x. Then, 4/3 = x/21 and x = 28.
For the 4th question, it is scaled down by 3, so we need to scale the 80 in long up by 3, to make it 240 inches long.
Finally, for the last question, the maximum scale factor is 4, because of 12/3. Scale this the same way for the width and you get 2*4 = 8 in.
