Answer:

2 Tetrahedrons combined create an Octahedron.

Step-by-step explanation:

Despite the lack of information.

The Plato Polyhedrons are Tetahedron, Cube (Hexaedron), Dodecahedron, Octahedron and Icosahedron. They are regular ones, made up by regular plane figures.

An Octahedron can be built by combining two pyramids. Each Tetrahedron is made up by 4 equilateral triangle.

Answer:

x = 61.92751306

Step-by-step explanation:

Since this is a right triangle, we can use trig functions

tan theta =  opposite / adjacent

tan x = 15/8

Take the inverse tan on each side

tan ^ -1 (tan x) = tan ^ -1 (15/8)

x = 61.92751306

Answer:

Step-by-step explanation:

tan x = 15/8

tanx = 15/8    ... 1

cot x = 8/15..... 2

multiply 1 and 2

tanx * cotx = 15/8 * 8/15

x [ tan * 1/tan]  =  1

x = 1

Answer:

(-2,-1)

Step-by-step explanation:

Reflection across the x-axis is: [tex](x,y)\rightarrow(x,-y)[/tex]

We need to multiply the y-value of the pre-image by negative one to get reflected across the x-axis.

1 * -1 = -1

So:

[tex](-2,1)\rightarrow(-2,-1)[/tex]

Answer:

The slope is zero.

Step-by-step explanation:

Imagine the graph. [tex]y=3[/tex] would simply be a horizontal line. All horizontal lines have slopes of 0. You can also use the slope formula if necessary to try it out.

On the other hand, if the line was vertical (e.g. [tex]x=3[/tex]), then the slope would be undefined.

Answer: The line y=3 is a horizontal line, and a horizontal line has a slope of zero. The only lines parallel to a horizontal line are other horizontal lines. Therefore, there is no slope.

Step-by-step explanation:  y=3  rewritten as  y=0x+3

For a line equation for the form of y=mx+b, the slope is m

m=0

Answer:

∠x = 90°

∠y = 58°

∠z = 32°

Step-by-step explanation:

The dimensions of the angles given are;

∠B = 32°

Whereby ΔABC is a right-angled triangle, and the square fits at angle A, we have;

∠A = 90°

∴ ∠B + ∠C = 90° which gives

32° + ∠C = 90°

∠C = 58°

∠x + Interior angle of the square = 180° (Sum of angles on a straight line)

∴ ∠x + 90° = 180°

Hence;

∠x = 90°

∠x + ∠y + 32° = 180° (Sum of angles in a triangle)

∴ 90° + ∠y + 32° = 180°

∠y = 180 - 90° - 32° = 58°

∠y + ∠z + Interior angle of the square = 180° (Sum of angles on a straight line)

58° + ∠z +90° = 180°

∴ ∠z = 32°

∠x = 90°

∠y = 58°

∠z = 32°

Answer:

-16-(-45)

Step-by-step explanation:

If we subtract -45 from -16, we'll get the result 29

=> -16-(-45)

=> -16+45

=> 29

Answer:

-21 and 40.

Step-by-step explanation:

The two numbers from the list that have a difference of 29 are:

-21 and 40.

-21 - (-40)

= -21 + 40

= 29

The two numbers are -21 and 40.

Answer:

Area is 126.5 inches^2

Step-by-step explanation:

Mathematically, to calculate the area of the trapezoid, we use the following mathematical formula;

A = 1/2(a + b) h

here, a and b represents the two parallel sides which is 9 and 14 inches here and h which is the height is 11

Plugging these values into the equation, we have

A = 1/2(9 + 14)11

= 1/2(23)11 = (23*11)/2 = 126.5 inches^2

Answer:

f = -3

Step-by-step explanation:

→Distribute the 6 to (10 + 14f), and the 4 to (-12 + 12f):

6(10 + 14f) = 4(-12 + 12f)

60 + 84f = -48 + 48f

→Subtract 48f from both sides:

60 + 36f = -48

→Subtract 60 from both sides:

36f = -108

→Divide both sides by 36:

f = -3

Answer:

-3

Step-by-step explanation:

6(10 + 14f) = 4(–12 + 12f)

Expand out

60 + 84f = -48 + 48f

Subtract -48 to both sides to bring the numerical to one side

108 + 84f = 48f

Minus 84f from both sides to isolate 12

108 = -36f

Divide both sides by -36 to isolate f

-3 = f

Answer: $14.88x + $8.88y

Step-by-step explanation:

Value of adult tickets = 14.88 * x

Value of child tickets = 8.88 * y

So the equation is

14.88x + 8.88y

Answer:

(C)Determine the principal square root of both sides of the equation.

Step-by-step explanation:

Given: Isosceles right triangle XYZ (45°–45°–90° triangle)

To Prove: In a 45°–45°–90° triangle, the hypotenuse is [tex]\sqrt{2}[/tex] times the length of each leg.

Proof:

[tex]\angle XYZ$ is 90^\circ$ and the other 2 angles are 45^\circ. \\\overline{XY} = a, \overline{YZ}= a, \overline{XZ}= c.\\[/tex]

Because triangle XYZ is a right triangle, the side lengths must satisfy the Pythagorean theorem, [tex]a^2 + b^2 = c^2[/tex]

Since a=b in an isosceles triangle:

[tex]a^2 + a^2 = c^2\\$Combining like terms\\2a^2 = c^2\\$Determine the principal square root of both sides of the equation.\\\sqrt{c^2}=\sqrt{2a^2} \\\\c=a\sqrt{2} \\[/tex]

Therefore, the next step is to Determine the principal square root of both sides of the equation.

Answer: C and hoped this helped and please mark as brainlest.

Answer:

x = 4

Step-by-step explanation:

First you want to distribute the terms:

2(4x+3) = 10x-2

8x+6 = 10x-2

then combine like terms:

8x+6 = 10x-2

-8x         -8x

6 = 2x-2

+2      +2

8 = 2x

x = 4

Answer:

I'm 50% sure it is B)8,4

We want to find the coordinates of a point D such that AB is parallel to CD.

The coordinates of D are: D (10, 7).

We have that:

If we want CD to be parallel to AB, then the change in the components between D and C must be the same as the change in the components between B and A.

The change in the x-component between B and A is:

8 - 1 = 7

The change in the y-component between B and A is:

4 - 7 = -3

Then the coordinates of D are given by:

x = 3 + 7 = 10

y = 10 + (-3) = 7

The coordinates of D such that CD is parallel to AB are:

D(10, 7).

Notice that this is just an option, there are a lot of other possible coordinates that will also make CD parallel to AB, this is just the easier one to find.
