The answer is G, because you need to put the variables that go together with the same person.
ANSWER
The constant of proportionality is 24.
EXPLANATION
If the volume of a box (V) varies directly with it's length (l), then we can write the mathematical statement,
![V\propto l](https://tex.z-dn.net/?f=V%5Cpropto%20l)
We introduce the constant of proportionality k, and write the equation,
![V = k l](https://tex.z-dn.net/?f=V%20%3D%20k%20l)
When V=288, l=12.
We substitute these values to obtain;
![288 = 12k](https://tex.z-dn.net/?f=288%20%3D%2012k)
Divide both sides by 12,
Answer:
12 ft

Rectangle:
A = 9 x 16
A = 144
Square:
A = √144
A = 12
Answer:
add middle numbers and divide by two.
Step-by-step explanation:
When you need to find the median with an odd set of numbers, you arrange the numbers in order from least to greatest and find the number in the middle of the set:
1 2 3
median is 2.
But, when you have an even set of numbers, you take the two middle numbers, add them together, then divide them by two (it's like finding the mean of those two middle numbers):
1 2 3 4
2 3
2+3=5
5÷2=2.5
median is 2.5
Okay. So, there will be 12 small turbines, with 3 blades on each of them. 12 * 3 is 36. Marco will need 36 wind turbine blades total. 4 of them cost $79.64. 36/4 = 9. We would multiply 79.64 by 9 to get the cost for all blades. 79.64 * 9 is 716.76. The total cost for 36 blades would be $716.76.
