Euler's formula for a polyhedron is given by:

Make E, the subject of the formula:

Put F = 20, V = 12, to obtain E,

Therefore, there are 30 edges
Answer:
1/2 cup per friend
Step-by-step explanation:
He has 1 gallon of fruit sorbet to serve to 32 friends
Note that:
1 US gallon of water (gal) = 16.00 US cups of water (cup)
16 cups/1 gallon x 1 gallon/32 friends
1/2 cup per friend
Answer:
x=10
m=3
Step-by-step explanation:
The angles are the same since the sides are the same length (isosceles triangle)
55 = 5x+5
Subtract 5
55-5 =5x+5-5
50 = 5x
Divide by 5
50/5 = 5x/5
10=x
The altitude is a perpendicular bisector so
5m-3 = 2m+6
Subtract 2m from each side
5m-3-2m = 2m+6-2m
3m-3 = 6
Add 3 to each side
3m-3 +3 =6+3
3m =9
Divide by 3
3m/3 = 9/3
m =3
2x+3y=160
-2x+7y=25 I hope that helps!!
I’m gonna say that the answer is 5: 14
