We know that
The Euler's formula state that, the number of vertices, minus the number of edges, plus the number of faces, is equal to two
V - E + F = 2
clear F
F=2-V+E
in this problem
V=8
E=14
F=?
so
F=2-8+14
F=8
the answer is8 faces
Answer:
18 students is the amount that passed the test
so the fraction would be 18/24, which can be simplified to 3/4, which is 75% of the class.
75% of the class passed
0.75% of the class passed
We have two rectangles such as:
Rectangle 1 = X
Rectangle 2 = Y
Where the ratio of the two is:
Ratio = X / Y = 3/4
If x length is 10, we can solve for y length such as:
10 /Y length =3/4
Y length = 40/3 = 13.33
If x width is 5, then we can solve for y width such as:
5/y width = 3/4
y width = 20/3 = 6.67
The Perimeter of Pan Y is shown below:
Y perimeter = 2(6.67) + 2(13.33)
Y perimeter = 40
The answer is 40 inches.
3y = 2x - 6
y = 2/3x - 2
y = 2/3x + c , ( - 2, 5 )
5 = 2/3 ( -2 ) + c
3c = - 6
c = - 2
y = 2/3x - 2
i am a mathematics teacher. if anything to ask please pm me
I'm gonna go with D. I really hope that's right math isn't my strong suit lol
