Step-by-step explanation:
<u>Hexahedron</u>
A hexahedron has 6 faces. A <em>regular</em> hexahedron is a cube. 3 square faces meet at each vertex.
If the hexahedron is not regular, depending on how those faces are arranged, a slice near a vertex may intersect 3, 4, or 5 faces. The first attachment shows 3- and 4-edges meeting at a vertex. If those two vertices were merged, then there would be 5 edges meeting at the vertex of the resulting pentagonal pyramid.
A slice near a vertex may create a triangle, quadrilateral, or pentagon.
<u>Icosahedron</u>
An icosahedron has 20 faces. The faces of a <em>regular</em> icosahedron are all equilateral triangles. 5 triangles meet at each vertex.
If the icosahedron is not regular, depending on how the faces are arranged, a slice near the vertex may intersect from 3 to 19 faces.
A slice near a vertex may create a polygon of 3 to 19 sides..
Answer:
Step-by-step explanation:
Given :
→ For Purple People Eater, she used 3 pints of red paint for every 5 pints of blue paint.
i.e, The ratio of red paint to blue paint is 3:5
→ For Purple Majesty, she used a blue to red paint ratio of 7 to 4.
i.e, The ratio of red paint to blue paint is 4:7
To find :
1) Compare the ratios of red paint to blue paint.
2) The ratio for Purple People Eater can be expressed in fraction form as :
3) The ratio for Purple Majesty can be expressed in fraction form as :
4) To compare these fractions, rewrite them with a common denominator
For common denominator
Multiply numerator and denominator by 4 in
Multiply numerator and denominator by 5 in
Common denominator is 20
