A positive relationship. The reason being y=3x represents the overall slope of the equation, as well as the point (3,9) and (5,15) are the outcomes of the equation. For instance when you start at the origin with the equation you move up 3 and move to the right 1 this is the same with (3,9) and (5,15) just continuing the pattern with these points.
(e.g: (1,3), (2,6), (3,9), (4,12), (5,15).)

How do I find the volume of this right triangular prism?
frozen [14]
I’ll try to make a step by step demonstration! Feel free to skip to step 5 for the answer, though
1. The formula for a right triangular prism is (1/2)*base*height*length, and we know what the base (4 cm) and length (8 cm) are, but not the height
2. To find the height we must divide the side triangle into two, which then gives us two right triangles
3. Focusing on just one of the right triangles, its base will be 2 cm rather than 4 (as it has been divided by two) and its hypotenuse will be 4 cm; using Pythagorean’s theorem (a^2 + b^2 = c^2), solve for the missing side (the height), which should end up being √12
4. Multiply! (1/2)4*√12*8 ≈ 55.425
5. Round to the nearest tenth —> 55.4
I hope this helped somewhat! Comment if clarification is needed

Three boards are placed end to end to make a walkway. The first board is 4 feet inches 10 long, the second board is 2 feet 11 in
Strike441 [17]

Answer:

12 ft 2 in.

Step-by-step explanation:

Conversion: 1 ft = 12 in.

Add the lengths of the boards.

4 ft 10 in. + 2 ft 11 in. + 4 ft 5 in. =

= 4 ft + 2 ft + 4 ft + 10 in. + 11 in. + 5 in.

= 10 ft + 26 in.

= 10 ft + 24 in. + 2 in.

Since 1 ft = 12 in., then 24 in. = 2 ft.

= 10 ft + 2 ft  + 2 in.

= 12 ft 2 in.

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.
