PyramidRectangular PrismCylinderConeTriangular Prism==============================================
Explanation:
The formula for the volume of a pyramid is (1/3)*B*h, where B is the area of the base. If we're dealing with a rectangular pyramid, like those found in Egypt, then the area of the base is B = length*width. The volume for a prism is found by multiplying length (L), width (W), and height (H). So V = LWH. Think of having a 2 by 3 rectangle of blocks. We would have 2*3 = 6 blocks in total. Then if we have 5 layers of these stacked then we have 2*3*5 = 6*5 = 30 blocks in total. This is one way to visualize how the volume formula works.To get the volume of a cylinder, we multiply the area of the base (pi*r^2) by the height (h). So that's where pi*r^2*h comes from.The volume of a cone is 1/3 that of a cylinder's volume. This is when the cone and cylinder have the same radius, and also the same height. It's not required that r = h.Since all of the other answer choices are used up, the only thing left is "triangular prism". It's strongly implied here that B is the area of the triangular base. Though the formula Bh applies to any prism and it doesn't have to be a triangular prism. Note how B = LW, so Bh is the same as LWH, meaning that a rectangular prism can use the Bh formula.Please help! will give brainliest!!

Find the value of x when (a) 9 : x : : 54 : 48 (b) 2, 6 , x are in continued proportion
Answers
Answer:
a) x = 8
b) x = 18
Step-by-step explanation:
Given that
9 : x : : 54 : 48
This may be rewritten as
9/x = 54/48
cross multiply
9 * 48 = 54 * x
Divide both sides by 54
x = 9 * 48/54
= 8
b Given that 2, 6, x are in continued proportion then
2/6 = 6/x
2 * x = 6 * 6
x = 36/2
= 18
Solve each equation: -5(5x+5)+3(5x+3)=-4x-6x
Answers
Answer:
x= -1.118
Step-by-step explanation:
Firstly you need to start with the bracket
-5(5x +5) + 3(5x +3)
=( -25x +25) + (15x +9)
= -25x +25 +15x +9= -4x -6x
secondly you join the like terms together
25+9= -4x -6x +25x -15x
34= -38x
-38x ÷ 34
x= -1.118

Answer:

Step-by-step explanation:
The formula for finding the length of a side of a right triangle is:
A^2 + B^2 = C^2 (c being the hypotenuse.)
We know what the length of the hypotenuse and one of the legs is, so we can solve by taking B^2 (the leg measuring 12) and subtracting it from C^2 (the hypotenuse) and then finding the square root of C^2.
20^2 - 12^2 = 256
or in simpler terms
20^2 - 144 = 256
Then, if we find the square root of 256 we get 16. We can check our work by substituting it back into the equation
16^2 + 12^2 = 20^2
or in simpler terms
256 + 144 = 400
So the length of the missing leg is 16. I hope this helps :)
Answer:
C. 16
Step-by-step explanation:
In order to find one side of a right triangle, given two sides, you can use the Pythagorean theorem: [tex]A^2+B^2=C^2[/tex]
We already have the values of one of the bases (12) and the hypotenuse (20), so we are looking for the second base. So, we have the values of B and C, and we need to find A.
To find A, put the values you already have into the formula as follows:
[tex]A^2+12^2=20^2[/tex]
Next, square each value:
[tex]A^2+144=400[/tex]
Subtract 144 from 400 to simplify the equation.
[tex]A^2=256[/tex]
And finally, find the square root of 256 to find A.
[tex]A=16[/tex]
Final answer:
C. 16

Triangle QRS has coordinates Q(-2, -2), R(0, 3), and S(4, -2) and is dilated by a scale factor of 2. Determine the new coordinates of point S', and state whether the dilation is an enlargement or a reduction
Answers
Given:
Triangle QRS has coordinates Q(-2, -2), R(0, 3), and S(4, -2) and is dilated by a scale factor of 2.
To find:
The new coordinates of point S', and state whether the dilation is an enlargement or a reduction.
Solution:
If a figure is dilated by factor k with origin as center of dilation, then
[tex](x,y)\to (kx,ky)[/tex]
Where, 0<k<1 is reduction and k>1 is enlargement.
The figure is dilated by scale factor 2 which is greater than 1, so the dilation is an enlargement. The rule of dilation is:
[tex](x,y)\to (2x,2y)[/tex]
Using this rule, we get
[tex]S(4,-2)\to S'(2(4),2(-2))[/tex]
[tex]S(4,-2)\to S'(8,-4)[/tex]
Therefore, the new coordinates of point S' are (8,-4).
write the expression in exponential form.

A ratio of two numbers is equal to 3:8. If the smaller number is 12,find the greater number.
Answers
The other no. is:
32
As you can see that in the ratio given, 3 is the smaller no. and 12 too.
So when we divide 12 by 3, we get 4
Then to find the other no. we need to multiply 4 with 8 (which is the other no. in the ratio given)
Therefore, we get the other no. as 32
And also when you divide 12 by 32,
You get the answer as 3 by 8 (which is the given ratio)

Write an equation that represents the total cost for pop music bundles. Write another equations to represent the total cost for rock music bundles. Identify the variables in the equations.
Answers
Answer:
Equation for the total cost for pop music bundles = $ 1200 x + 300
Where variable is the Cost.
Equation for the total cost for rock music bundles = $ 950 x + 250
Where variable is the Cost.
Step-by-step explanation:
P.S - The exact question is -
Given - The Music Express is going to buy music bundles from a
company that is going out of business. The company
charges different amounts for bundles of pop and rock
music:
Cost for each pop music bundle is $1200
Cost for each rock music bundle is $950
One - time fee for rights to the pop music is $300
One - time fee for rights to the rock music is $250.
To find - Write an equation that represents the total cost for pop
music bundles.
Write another equations to represent the total cost for rock
music bundles.
Identify the variables in the equations.
Proof -
Given that,
Cost for each pop music bundle is $1200.
Cost for each rock music bundle is $950.
One - time fee for rights to the pop music is $300.
One - time fee for rights to the rock music is $250.
Let the total music bundles buy = x
Now,
Given, Cost for 1 pop music bundle = $1200
⇒Cost for x pop music bundles = $ 1200 x
Also given,
One - time fee for rights to the pop music is $300.
∴ we get
Equation for the total cost for pop music bundles = $ 1200 x + 300
Where variable is the Cost.
Now,
Given, Cost for 1 rock music bundle = $950
⇒Cost for x pop music bundles = $ 950 x
Also given,
One - time fee for rights to the pop music is $250.
∴ we get
Equation for the total cost for rock music bundles = $ 950 x + 250
Where variable is the Cost.

Answer:
(-2, 6)
Step-by-step explanation:
Plug in one of the equations into the y-variable (doesn't matter which):
2x + 10 = -4x - 2
Combine like terms by adding the 4x to both sides. This makes it cancel out on the right side, and 2x + 4x on the right side is 6x:
6x + 10 = -2
Combine like terms by subtracting 10 from both sides, making it cancel out on the left side, and on the right: -2 - 10:
6x = -12
Then isolate the x-variable by dividing both sides by 6:
x = -2
Taking the -2, plug it into an x-variable in either of the equations:
y = 2x +10
y = 2(-2) + 10
y = -4 + 10
y = 6

Complete question :
Lucy has block letters that are in the shape of cubes with sides 2 3 foot long. She has a box which is 1 1 3 foot long, 2 3 foot wide, and 2 3 foot tall. Find the number of block letters that will fit in the box.
Answer:
1/2
Step-by-step explanation:
Number of block letters that will fit in :
Volume of box ÷ volume of each letter cube
Volume of each letter cube = (side length)³ = (2/3)³ = 8/27 ft³
Volume of box = length * width * height
Volume of box = 1 1/3 * 2/3 * 2/3
Volume of box = 4/3 * 2/3 * 2/3 = 16 / 27 ft³
Therefore ;
8/27 ÷ 16/27
8/27 * 27/16
= 8/16
= 1/2
