How many non-congruent triangles can be formed by connecting 3 of the vertices of the cube?
alexira [117]

Answer:

The number of non-congruent triangles that can be formed by connecting 3 of the vertices of the cube is 3 non-congruent triangles

Step-by-step explanation:

From the three dimensional shape of a cube, triangles can be constructed from;

1) 6 side faces

2) 4 front face to opposite vertices triangles

3) 4 rear face to opposite vertices triangles

Each face can produce ₄C₃ = 4 triangles

Therefore;

The total number of triangles that can be formed = 4 × 6 + 4 × 4 + 4  × 4 = 56 triangles

Of the 56 triangles, it will be found that all 24 triangles from the different 6 direct faces will have the same dimension of 1, 1, √2 are congruent

The 24 triangles formed by the sides of the faces and an adjacent diagonal have the same dimension of 1, √2, √3 and are congruent

The 8 triangles formed by joining the three diagonals have the same dimension of √2, √2, √2 are congruent

Therefore, the 56 triangles comprises of a combination of three non-congruent triangle.

There are only 3 observed non congruent triangles formed by connecting three of the vertices of the cube.

Lucy and Ethel’s favorite store was having a sale. Lucy bought 10 shirts and 4 pairs of jeans and spent $280. Sabrina bought 12
Sphinxa [80]

Answer:

Each shirt costs 12 dollars.

Each pair of pants cost 40 dollars.

Step-by-step explanation:

<u>Let x represent the shirts </u>

<u>Let y represent the pair of jeans</u>

10x + 4y = $280

12x + 5y = $344

<u>Use elimination method to eliminate y</u>

• Multiply the entire first equation by 5.

• Multiply the second entire equation by -4.

5(10x +4y = $280)

-4(12x + 5y = $344)

50x + 20y = 1400

-48x -20y = -1376

2x = 24

x = 12

Each shirt costs 12 dollars.

<u>Solve for how much each pair of jeans costs.</u>

10(12) + 4y = 280

120 + 4y = 280

4y = 160

y = 40
