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
The formula for the area of a trapezoid is A=1/2(base one+base two)h
All you have to do is find the base one, base two, and height using the given information and then plug it into the equation.
He has 12 quarters and 15 dimes. 12 x .25=3. 15 x .1 = 1.5
1.5 + 3 = 4.5
Hope this helps
Answer:
$1,250 a year
Step-by-step explanation:
25,000,000*0.0002=5000kg of zinc
5000/4=$1,250
So that is $1,250 a year.
Answer:
59
Step-by-step explanation:
Find the diagram attached
From the diagram, we can see that both given angles are vertically opposite angles, hence they are equal
3x - 33 = 2x+26
3x-2x = 26 + 33
x = 59
Hence the value of x is 59
