Answer:
≈ 488.8
Step-by-step explanation:
So we wanna find x for 0.156x = 76.252;
What we have to do is to divide both sides of the equation by 0.156 to isolate the variable
If you are allowed to use a calculator then you can get the answer:
It equals around 488.8
If you want to solve it by hand, you can multiply both by 1000 to get:
76252 divided by 156.
Answer:
Regular Pentagon
Step-by-step explanation:
A regular icosahedron is a twenty-faced polyhedron, each face being an equiangular triangle. Each vertex is joined together by 5 faces, therefore the polygon formed at each vertex is a regular pentagon.
We can also figure out the number of faces at each vertex using Euler's formula
F+V=E+2
F=number of faces = 20
E=number of edges = number of triangular faces * edges/triangle /2
(since each edge is shared between two faces)
= 20*3/2
=30
Number of vertices
= E+2-F = 30+2-20 = 12
So number of edges meeting at each vertex
= 30 / (12/2) = 30/6 = 5
(12/2 because each edge joins two vertices).
