Answer:
20
Step-by-step explanation:
Given: F = 11, C = 11, E=?
By Euler's formula, we have:
![F + V - E = 2 \\ \therefore \: 11 + 11 - E = 2 \\ \therefore \:22 - E = 2 \\ \therefore \:22 - 2 = E \\ \huge \red{ \boxed{\therefore \: E = 20}}](https://tex.z-dn.net/?f=F%20%2B%20V%20-%20E%20%3D%202%20%5C%5C%20%20%5Ctherefore%20%5C%3A%2011%20%2B%2011%20-%20E%20%3D%202%20%5C%5C%20%20%5Ctherefore%20%5C%3A22%20-%20%20E%20%3D%202%20%5C%5C%20%20%5Ctherefore%20%5C%3A22%20-%20%202%20%3D%20E%20%20%5C%5C%20%20%5Chuge%20%5Cred%7B%20%5Cboxed%7B%5Ctherefore%20%5C%3A%20E%20%3D%2020%7D%7D)
Hence, the solid will have 20 edges.
Answer:
18
Step-by-step explanation:
8 3/4 + 9 2/8
We can simplify 2/8 by dividing the top and bottom by 2
8 3/4 + 9 1/4
Add the whole numbers
8+9 = 17
3/4 + 1/4 = 4/4 = 1
Add this to the whole numbers
17+1 = 18
Answer:
65
Step-by-step explanation:
Answer:
y=-3/4x +11.25
Step-by-step explanation:
You keep the -3/4x the same because it is also your slope so that the graphs never touch. But to get it to cross the point (3,9) you need to move the graph up. Also known as shifting the graph. You would change the y-intercept and follow the constant slope to check whether the point is on the graph. You do it a couple times with different y-intercepts to find the correct graph. :3
