Answer:
You will save $20
Step-by-step explanation:
30x5=150-130=$20
For this case we observe that the dimensions of the original piece are:
3 feet
2.5 feet
Let's multiply these dimensions by a scale factor k:
3 * k
2.5 * k
We match the new dimensions with their respective values:
3 * k = 6
2.5 * k = 5
Clearing k we have:
k = 6/3 = 2
k = 5 / 2.5 = 2
Since the value of k is the same, then the pieces are similar.
Answer:
The pieces are similar.
The ratio of their corresponding side lengths is:
k = 2
Answer:
r = 3
Step-by-step explanation:
q = k / 
k = q
= 1.2 x 3 x 3 = 10.8
q = 10.8/
1.2 = 10.8/
r =
= 3
