Pyramid A has a triangular base where each side measures 4 units and a volume of 36 cubic units. Pyramid B has the same height, but each side of its base is 6 units long.
Answer:
The volume of pyramid B is 81 cubic units
Step-by-step explanation:
Given
Pyramid A
[tex]s = 4[/tex] -- base sides
[tex]V = 36[/tex] -- Volume
Pyramid B
[tex]s = 6[/tex] --- base sides
Required
Determine the volume of pyramid B [Missing from the question]
From the question, we understand that both pyramids are equilateral triangular pyramids.
The volume is calculated as:
[tex]V = \frac{1}{3} * B * h[/tex]
Where B represents the area of the base equilateral triangle, and it is calculated as:
[tex]B = \frac{1}{2} * s^2 * sin(60)[/tex]
Where s represents the side lengths
First, we calculate the height of pyramid A
For Pyramid A, the base area is:
[tex]B = \frac{1}{2} * s^2 * sin(60)[/tex]
[tex]B = \frac{1}{2} * 4^2 * \frac{\sqrt 3}{2}[/tex]
[tex]B = \frac{1}{2} * 16 * \frac{\sqrt 3}{2}[/tex]
[tex]B = 4\sqrt 3[/tex]
The height is calculated from:
[tex]V = \frac{1}{3} * B * h[/tex]
This gives:
[tex]36 = \frac{1}{3} * 4\sqrt 3 * h[/tex]
Make h the subject
[tex]h = \frac{3 * 36}{4\sqrt 3}[/tex]
[tex]h = \frac{3 * 9}{\sqrt 3}[/tex]
[tex]h = \frac{27}{\sqrt 3}[/tex]
To calculate the volume of pyramid B, we make use of:
[tex]V = \frac{1}{3} * B * h[/tex]
Since the heights of both pyramids are the same, we can make use of:
[tex]h = \frac{27}{\sqrt 3}[/tex]
The base area B, is then calculated as:
[tex]B = \frac{1}{2} * s^2 * sin(60)[/tex]
Where
[tex]s = 6[/tex]
So:
[tex]B = \frac{1}{2} * 6^2 * sin(60)[/tex]
[tex]B = \frac{1}{2} * 36 * \frac{\sqrt 3}{2}[/tex]
[tex]B = 9\sqrt 3[/tex]
So:
[tex]V = \frac{1}{3} * B * h[/tex]
Where
[tex]B = 9\sqrt 3[/tex] and [tex]h = \frac{27}{\sqrt 3}[/tex]
[tex]V = \frac{1}{3} * 9\sqrt 3 * \frac{27}{\sqrt 3}[/tex]
[tex]V = \frac{1}{3} * 9 * 27[/tex]
[tex]V = 81[/tex]

Sum of interior angles of a quadrilateral is 360°
110° + 130° + x + x - 3° = 360°2x = 360° - 237°2x = 123°x = 61.5°(18)
Sum of interior angles of a hexagon is 180°*(6 - 2) = 720°
2*90° + 2x + 2(x + 22°) = 720°90° + x + x + 22° = 360°2x = 360° - 112°2x = 248°x = 124°(19)
Interior angles of a given pentagon are all marked as congruent, so the exterior angles are congruent too.
Sum of exterior angles is 360°.

Answer:
the answer is B.336
Step-by-step explanation:
got it right on ed
There are 336 different ways are there to present those ribbons if the order matters.
What is the combination?A combination is a mathematical technique that determines the number of possible arrangements in a collection of items where the order of the selection does not matter.
Eight students are competing for a blue, red, and yellow ribbon for their agriculture project.
Different ways are there to present those ribbons if the order matters.
By permutations, we have to calculate the number of different ways to arrange the ribbon is;
[tex]=3 \times 2\times 1\\\\=6[/tex]
Now, we have to calculate the different ways to choose 3 winners from 8 is;
[tex]=8\times 7\times 6\\\\=336[/tex]
Therefore, the correct option is (b), 336 ways are there to present those ribbons if the order matters.

A prism has a volume of 405 cubic inches.
4.5 in.
15 in.
Which is the correct substitution for finding the height of the prism?
Answer:
405 = 15 times 4.5 times h
Step-by-step explanation:
Complete question
A prism has a volume of 405 cubic inches.
A prism has a length of 15 inches, height of h, and width of 4.5 inches
Which is the correct substitution for finding the height of the prism?
A V = l w h. 405 = 15 + 4.5 + h.
B V = l w h = 15 times 4.5 times 405
C V = l w h = 15 times 4.5 times 15
D V = l w h. 405 = 15 times 4.5 times h
Find the diagram attached
Volume of the prism is expressed as;
V = lwh
l is the length
w is the width
h is the height
Given the following
l = 15inches
w = 4.5inches
Required
Expression to calculate the height g
Substitute the given values into the formula
V = lwh
405 = 15 * 4.5 * h
Hence the required option is 405 = 15 times 4.5 times h
Answer:
405 = 15 times 4.5 times h

Tom decides to pick up some pizzas and drinks for his family. He notices that the pizza costs the same as 7 drinks. The 2 pizzas and 8 drinks cost $33. What is the price of each item?
Answer:
Drinks = $1.5
Pizza = $10.50
Step-by-step explanation:
let d = drinks
p = pizza
p = 7d equation 1
2p + 8d = 33 equation 2
from equation 1, we know the price of one pizza, the price of two pizzas can be determined by multiplying by 2
2p = 7d x 2 = 14d eqn 3
Substitute for 2p in equation 2
14d + 8d = 33
22d = 33
Divide both sides of the equation by 22
d = $1.5
Substitute for d in equation 1
p = 1.5 x 7 = $10.5

 please help me ahhh im doing 8th grade math with pythagorean theorem
Step-by-step explanation:
The pythagorean theorem is the sum of the two legs squares equal the hypotenuse squared.
The hypotenuse is the longest side so 3.5 is our hypotenuse.
Apply formula to see of true.
