Answer:
yes they form a proportion
Answer:
It would cost $232.32, this answer is rounded.
Step-by-step explanation:
The formula for the volume of a square pyramid is:
![V=a^2\frac{h}{3}](https://tex.z-dn.net/?f=V%3Da%5E2%5Cfrac%7Bh%7D%7B3%7D)
So its just:
![8.8^2\frac{12.5}{3} = 322.67 cm^3](https://tex.z-dn.net/?f=8.8%5E2%5Cfrac%7B12.5%7D%7B3%7D%20%3D%20322.67%20cm%5E3)
Then you just multiply the volume by the cost per cubic centimetre:
![322.67cm^3*$0.12=$38.704](https://tex.z-dn.net/?f=322.67cm%5E3%2A%240.12%3D%2438.704)
After just multiply the cost of one by how many you want, which is 6:
![38/704*6=232.32](https://tex.z-dn.net/?f=38%2F704%2A6%3D232.32)
Answer:
This function represents a direct variation because it passes through the origin and has a constant rate
Answer: 72.5
Step-by-step explanation:
The average of 2 points is the midpoint so if I add 70 and 75 to get 145 and divide by the number of numbers which is 2 I get 72.5
It would be A because it is 5 units down from the points
