When you have to describe a 3D shape you have to keep the following definitions in mind:
<em>1. The face of a 3D shape is a flat surface.</em>
The shape on the picture has 3 rectangular faces and 2 triangular faces, a total of 5 faces.
<em />
<em>2. The edge is where two faces meet.</em>
For the shape on the picture, there are 3 edges, where the rectangular faces meet each other, and then three edges where the rectangular faces meet each of the triangular faces, this shape has a total of 9 edges.
<em>3. The vertex is a corner, where the edges meet.</em>
There are three vertices on each end of the shape, so it has a total of 6 vertices.
A shape that has 5 faces, 9 edges, and 6 vertices is a triangular prism.
Answer: x=15 and y=6
Step-by-step explanation:
2y+49 + 8y+71 = 180 (Then solve)
5x+44 + 3x+16 = 180 (Then solve)
First you divide the total with the amount of hours you worked
45/5 = 9
9 is the amount of money you earn per hour
so your answer is $9 per hour
hope this helps
