Answer:
0.58
Step-by-step explanation:
P1 > 1 = 5/6
P2 > 1 = 5/6
P3 > 1 = 5/6
P1*P2*P3 = 5/6*5/6*5/6
P = 0.58
The given ratio is:

To find the unit cost per ounce, we can use proportions as follows:

Now, solve for x:

The cost per ounce (unit cost) is then $0.12/oz
Before dilation:
the height of the triangle is h₁ = 7 - (-1) = 8
the width of the triangle is w₁ = 7 - (-5) = 12
After dilation:
the height of the is h₂ = 9-7 = 2
the width of the triangle is w₂ = -5 - (-8) = 3
The scale factor is h₂/h₁ = 2/8 = 1/4 = 0.25
Also, the scale factor is w₂/w₁ = 3/12 = 1/4 = 0.25
Answer: The scale factor is 0.25
