The perimeter is the total measurement of all the sides together.
P = 82
Perimeter is side + side + side and so on.
So here is what we have.
15.4 + 16.2 + 28.7 + d = 82
Add up what you have now
60.3 + d = 82
Subtract 60.3 from both sides to get D
d = 82 - 60.3
d = 21.7
NPV = ((((-220/1.1 +540)/1.1 -640)/1.1 +2080)/1.1 +590)/1.1 -1600
NPV = 406.76
The net present value is positive. It seems a little low for a 5-year commitment. It would need to be compared to other opportunities and the thresholds customarily used for such decisions. In the absence of any other information, an appropriate choice may be ...

Answer:
A dialation
Step-by-step explanation:
A dilation keeps the same figure but either makes it smaller or bigger depending on the scale factor. If the scale factor is bigger than 1, it will be bigger and if it's less than 1 it will be smaller.
We are given that ratio of cars Sam has built to cars Tyrone has built is 3:4.
Let us assume that Sam built 
cars and Tyrone built 
.
Since we are given that total number of cars they built is 42. Therefore, we can set up:
Therefore, Sam built 
cars and Tyrone built 
cars.
