What is the surface area of this triangular pyramid?

Answers

Answer 1

Answer:

here you go

Step-by-step explanation:

To find the slant height of triangular faces: The slant height of a triangular pyramid is generally represented by 's'. Add all the areas together. Thus, the surface area of a triangular pyramid formula is 1⁄2(a × b) + 3⁄2(b × s) in squared units.

Answer 2

The surface area of this triangular pyramid is 10.908 in².

We have,

Base of Triangle= 3 in

Height of Triangle= 3 inch

P = 3 inch

h = 4 inch

Now, slant height= √4² + 1.5² = √16+2.25 = 4.272 inch

So, the Surface Area of Triangular Pyramid

= base Area + 1/2 x 3 x 4.272

= 1/2 x 3 x 3 + 6.408

= 4.5 + 6.408

= 10.908 in²

Thus, the surface area of this triangular pyramid is 10.908 in².

A tetrahedron is a pyramid with a triangular base. Find the volume of the tetrahedron.

L = 3 in W = 4 in H = 11 in

Answers

Answer:

Tetrahedron generally known as triangular pyramid consists of 4 triangular faces, 6 edges and 4 vertices. The base of the tetrahedron is a triangle. All the vertices have the same atom that is bonded to the central metal atom which lies in the centre of the tetrahedron. We take as an example to see how the atoms actually bond in tetrahedron. It is quite visible from the image that 4 O-atoms lies on all the 4 vertices and 1 Si-atom lie in the centre.

Let’s find the slope of this equation

Slope formula:

(y2-y1/x2-x1)

Plug things in

(-3000-0/20-0)

(-3000/20)

Condense the fraction

Slope = -150 or lowering 150 feet per minute.

Let’s get point slope form, add in some points.

Point slope form:

y - y1 = -150(x - x1)

Plug things in

y - (-3000) = -150(x - 20)

y + 3000 = -150x + 3000

Subtract 3009

y = -150x

Plug in -36000 for y

(-36000) = -150x

Divide by -150

x = 240

You are correct, it took 240 minutes.

can you type out the equations in the triangle?

Hi there!

A triangles angles will always add up to 180°.

Therefore, we can add these equations to get 180° and then find x.

(4x-2) + (7x-2) + (5x-8) = 180°

Now we simply the equation by combining like terms.

16x -12 = 180°

Now we can solve for x. ^w^

16x -12 = 180°
+12 +12
~~~~~~~~~~~~~
16x = 192
/16 /16
~~~~~~~~~~~~~
x = 12

Yay! We found x. Now we plug it into each equation:

~ 4x-2
4(12)-2
48-2
46°

~ 7x-2
7(12)-2
84-2
82°

~ 5x-8
5(12)-8
60-8
52°

It’s always a good idea to check if these angles add up properly to 180°.

46° + 82° + 52° = 180°

Congrats! We are all done ^u^

The goalie on the Iceblades hockey team saves (blocks) 73% of the opponent's shots. With 10 minutes to go, the Iceblades are ahead by one goal, and they will win if the other team does not score.
The other team takes 5 shots in the final 10 minutes. The Iceblades do not score any more goals.
The table shows pairs of random digits. The pairs in each group simulate the 5 shots taken by the opponent.
Answer the questions to estimate the probability that the Iceblades will win the game.

1. The paired digits 00 to 99 represent 100 shots.
Let 00 to 72 = a shot that is saved. Which digits represent a goal scored? Explain.

2. Each group represents the 5 shots taken by the other team. To win the game, the Iceblades cannot let the other team score any goals.
For a group to be a success, how many of the 5 shots does the goalie need to save?

3. Group 1 is a success. Explain why.

4. In this simulation, which groups are successes? How many successes are there in the 10 groups?

5. Estimate the probability the Iceblades will win the game. Give your answer as a percent.
