B.) 15 - A = 6
Step-by-step explanation:
The equation shows that Marcella had $15 then bought something (A), and now she has 6 dollars left.
15 - A = 6
Answer:
The area of one side of the tank is
Step-by-step explanation:
A cube is a regular Polyhedron limited by six equal squares. It is also known as the regular hexahedron, or simply hexahedron.
The cube is a ortohedron, that is, it has its six faces straight and perpendicular to each other. In addition to being their rectangle faces, they are also square.
It has the following properties:
*Number of faces: 6
*Number of vertices: 6
*Number of edges: 12
*Number of edges from one vertex: 3
Being the length of the edge of the cube, then its Volume (V) is expressed by the formula: Being a the length of the edge of the cube
A fish tank is the shape of a cube. Its volume is , to calculate the are of one side of the tank, we know that each faces has the form of a square of area .
To calculate the value of a.
Then the area of square is
Substituting the value of a
A + 2A = 180
3A = 180
A = 60
2A = 120A
Answer:
No rotation will produce a polyhedron. The solids of rotation are non-polyhedral.
Step-by-step explanation:
Solids of rotation will always have a curved face, so they’re always non-polyhedral.
