Answer:
0.66653334
Step-by-step explanation:
The area of the face of the square is the side length x the side length. So 0.3333 x 0.3333 = 0.11108889. Since a square has 6 sides, multiply 0.11108889 with 6. So it equals 0.66653334.
We have to identify the given object.
A. Cube: The given object is not a cube because cube is a box-shaped solid object that has six identical square faces. But here, the given figure does not have the identical faces.
B. Polygon: The given object is not a polygon because a polygon is any 2-dimensional shape formed with line segments. But here, the given figure is not 2-dimensional.
C. Polyhedron: The given object is a polyhedron because a polyhedron is a solid in three dimensions with flat polygonal faces, straight edges and sharp corners or vertices. Therefore, it is a polyhedron.
D. Prism: The given object is a prism because a prism is a polyhedron consisting of two parallel, congruent faces called bases. This is called a rectangular prism because a Prism with rectangular bases is a Rectangular Prism.
E. Pyramid: The given object is not a pyramid because a pyramid is a 3-dimensional shape whose base is a polygon. Each corner of a polygon is attached to a singular apex, which gives the pyramid its distinctive shape. Each base edge and the apex form a triangle. The given object does not appears like this.
So, the given object is Polyhedron and Prism(rectangular).
Answer:
x= 2,
,y = 5
Step-by-step explanation:
Solve by Substitution :
// Solve equation [1] for the variable y
[1] y = 5x - 5
// Plug this in for variable y in equation [2]
[2] -4x + 2•(5x-5) = 2
[2] 6x = 12
// Solve equation [2] for the variable x
[2] 6x = 12
[2] x = 2
// By now we know this much :
x = 2
y = 5x-5
// Use the x value to solve for y
y = 5(2)-5 = 5
Solution :
{x,y} = {2,5}
