The area of the base of a triangular pyramid with faces that are equilateral triangles is 64 ft squared. Can you find the surface area of the pyramid? Explain. Here are the choices
A. No, because the area of the base of a pyramid is not related to the area of its faces, so the surface area cannot be found without more information.
b. No, because the base of a pyramid with equilateral triangle faces does not necessarily have the same area as its equilateral faces.
C.Yes, because the area of the base of a triangular pyramid with equilateral triangles for faces is the same as the area of each face.
D.Yes, because the area of the base will be the edge length of each face, which can be used to find the area of each face
Answer:
C.
Step-by-step explanation:
Yes, because the area of the base of a triangular pyramid with equilateral triangles for faces is the same as the area of each face.
So the surface area is 64 * 4 which is 256

A.
21x + 68
B.
33x + 68
C.
33x + 100
D.
33x + 84
Answer:
Step-by-step explanation:

84-16 = 68
The answer is 33x + 68
If the zeros of a quadratic functions are -2 and 4, which graph could represent the function?
Answer:
The Graph having the X-intercepts of (-2,0) and (4,0)
Step-by-step explanation:
The zeroes of the function is the X-intercept.
The graph that represent the function should be that it contains the x-intercept of (-2,0) and (4,0)
What is x-intercept?
Here the x-intercept means the x-coordinate of the point at which the line, curve, the surface should be intersected at the x-axis.
Since there are the zeros of the quadratic equation that contains -2 and 4
So here we can say that The graph that represent the function should be that it contains the x-intercept of (-2,0) and (4,0)

Rectangle A measures 3cm by (8x - 7)cm and rectangle B measures 4cm by (5x + 2)cm. Area of both rectangles is equal. Create the equation and find the value of x.
please help me i will mark you brainliest
Answer:
Equation: 3 (8x - 7) = 4 (5x + 2)
Value of x =7.25 cm
Step-by-step explanation:
Hi, to answer this question we have to apply the next formula:
Area of a rectangle: width x length
Replacing with the values given:
Area A = 3 (8x - 7)
Area B = 4 (5x + 2)
Since both areas are equal:
Area A = Area B
So:
3 (8x - 7) = 4 (5x + 2)
Solving for x:
24x -21 = 20x+8
24x-20x =8+21
4x =29
x =29/4=7.25 cm

The areas of the sides of a rectangular box are
10 in.2, 14 in.2, and 35 in.2 What is the volume of the box?
Answer:
4900 In. Squared
Step-by-step explanation:
The formula for calculating volume is Length X Base X Height
So as you can see, the way you would solve this problem si by doing
10 X 14 X 35 which would give you the final answer of
4900 Inches Squared or 4900 In.2
x/4 = -5
I need help
Answer:
-20
Step-by-step explanation:
because if you put -20 over 4, that simplifies out to -5
Answer:
x= -20
Step-by-step explanation:
To solve this problem, we have to get x by itself.
x/4= -5
x is being divided by 4. To reverse this, multiply both sides by 4, because multiplication is the opposite of division.
4*(x/4)=(-5)*4
The 4s on the left cancel, so we are left with:
x=-5*4
x=-20
To check our solution, we can substitute -20 back in for x.
x/4=-5
-20/4=-5
-5= -5
This is true, so we know that -20 is the solution.

The bottom part of this block is a rectangular prism. The top part is a square pyramid. You want to cover the block entirely with paper. How much paper do you need? Use a pencil and paper to explain your reasoning.
Also please look at the attachment.
Answer:
total paper required = 57 cm²
Step-by-step explanation:
given data
slant height b = 4 cm
base side h = 3 cm
block height h1 = 2 cm
solution
we get surface area of right squared pyramid by add here areas of all 4 triangles that is express as
area = 4 × Area of Triangles
area = 4 × [tex]\frac{bh}{2}[/tex]
area = 4 × [tex]\frac{4\times 3}{2}[/tex]
area = 24 cm²
and
surface are of the box is equal to the area of its 4 side faces + base
area = 4 × ( h × h1 ) + h²
area = 4 × ( 3 × 2 ) + 3²
area = 24 + 9
area = 33 cm²
so total paper required = 24 + 33
so total paper required = 57 cm²

A model skyscraper is made with a scale of 1 inch to 75 feet. What is the height of the model if the height of the building is 1,395 feet?
Answer:
18.6 inches
Step-by-step explanation:
As we have the scale between the model and the real skyscraper, and we also have the height of the real building, to find the height of the model we just need to use a rule of three:
1 inch -> 75 feet
x inches -> 1395 feet
x*75 = 1*1395
x = 1395 / 75
x = 18.6 inches
The height of the model skyscraper is 18.6 inches.

Answer:
c) 1. Distributive Property 2. Combine like terms 3. Addition Property of Equality 4. Division Property of Equality
Step-by-step explanation:
4x + 1/2(10x − 4) = 6
4x + 5x − 2 = 6 distirbuted 1/2 to 10x - 4
9x − 2 = 6 combinded like terms: x

The justifications are 1. Distributive Property 2. Combine like terms 3. Addition Property of Equality 4. Division Property of Equality options third and fourth are correct.
What is a linear equation?It is defined as the relation between two variables if we plot the graph of the linear equation we will get a straight line.
If in the linear equation one variable is present then the equation is known as the linear equation in one variable.
We have the equation:
[tex]\rm 4x+\frac{1}{2} (10x-4)=6[/tex]
4x + 5x -2 = 6 (Multiplication proeprty of equality or Distributive property)
9x - 2 = 6 (combine like term)
9x = 8 (addition property of equality)
x = 8/9 (division property of equality)
Thus, the justifications are 1. Distributive Property 2. Combine like terms 3. Addition Property of Equality 4. Division Property of Equality options third and fourth is correct.
