Answer:
1/10
Step-by-step explanation:
8/80
divide numerator and denominator by 8
8÷8=1
80÷8=10
0= 10
since 0 = 10 is false, there is no solution
Answer:
Step-by-step explanation:
Let
V
be the number of vertices of a polyhedron,
F
the number of faces of that polyhedron, and
E
be the number of edges. The quantity
χ
=
V
−
E
+
F
is called the Euler characteristic (of a polyhedron). In the case of convex polyhedra,
χ
=
2
.
Consider, for example, a tetrahedron (which is the simplest solid). It has 4 faces,
1

(

)
(
3
)
=
6
edges, and
1
3
(
4

(

)
=
4
vertices. Thus we have
V

E
+
F
=

−
6
+
4
=
2
.
Euler's formula holds for all Platonic solids (tetrahedron, cube, octahedron, dodecahedron, and icosahedron). Since a cube and an octahedron are dual polyhedra (each is formed by connecting the centers of the faces of the other), their
V
and
F
values are equal to the
F
an
V
values of the other. (The same is true for the dodecahedron and icosahedron).
Answer:
The opposite of multiplication is division. The opposite of division is multiplication. The opposite of taking a square root is squaring
