Answer:
Step-by-step explanation:
Let x be the track straights lengths
Let y be the track ends diameter and the other rectangle side lengths.
1800 = 2x + πy
y = (1800 - 2x) / π
A = xy
A = x((1800 - 2x) / π
A = (1/π)(1800x - 2x²)
dA/dx = (1/π)(1800 - 4x)
0 = (1/π)(1800 - 4x)
0 = 1800 - 4x
4x = 1800
x = 450 m
y = (1800 - 2(450)) / π
y = 900/π or approximately 286.5 m

Step-by-step explanation:
Answer:
My guess:
A. Consistent independent
B. Consistent dependent
C. Inconsistent
Step-by-step explanation:
The first is a repeated equation, so it is a consistent independent equation.
The second is consistent, trying to solve the value of Y. But it looks like it needs the other equation to complete it and solve the value of Y.
The third has no pattern, and isn't trying to solve any values, unlike the others. So it is inconsistent.
(Just a quick note, I do not have experience with this, but it is my best guess)
There are numerous ways you can do this, but take a look at the attachment to see how I did it. I hope it answers your question! :)
