Anyone know the answer and explanation? thank you!!​

Answer:

D

Step-by-step explanation:

The figure is a rectangular pyramid. The cross section is perpendicular to the rectangular base and passes through the top vertex of the figure. A triangle that does not have the same dimensions as one of the faces is formed. The sides of the new triangle are the heights of the triangles on the faces of the pyramid, and that is why their dimensions are different.

Answer:

A 256 units 3

Step-by-step explanation:

The volume of the cylinder given below is 256π units .

Given,

Radius of cylinder = 8 units

Height of cylinder = 4 units

Now,

Volume of cylinder is given by

V = π×r²×h

r = radius of base

h = height of cylinder

So,

Substitute the values in the formula,

V = π × 8² ×4

V = π × 64 × 4

V = 256π units .

Thus the volume of the cylinder is 256π units .

Answer:

z= -3

Step-by-step explanation:

[tex]\frac{1}{2} z[/tex] = [tex]\frac{-3}{4} + \frac{1}{4} z[/tex]

[tex]\frac{1}{2} z - \frac{1}{4} z[/tex] = [tex]\frac{-3}{4}[/tex]

[tex]\frac{2z - z}{4} = \frac{-3}{4}[/tex]

[tex]\frac{z}{4} = \frac{-3}{4}[/tex]

4z = -3×4

4z = -12

[tex]\frac{4z}{4} = \frac{-12}{4}[/tex]

z = -3

Hope this helps!!!

The value of z in the equation (1/2)z = - 3/4 + (1/4)z is 3/2.

An equation is written in the form of variables and constants separated by the operation of multiplication and division,

An equation states that terms in different forms on both sides of the equality sign are equal.

Multiplication and division do not separate the terms of an equation.

given, (1/2)z = - 3/4 + (1/4)z and we have to find the value of z or solve for z.

∴ (1/2)z = - 3/4 + (1/4)z.

(1/2)z - (1/4)z = 3/4.

(1/2)z = 3/4.

z = (3/4)×(2/1).

z = 6/4.

z = 3/2.

3500+750(5)=7250

Answer:

37°

Step-by-step explanation:

As we know the sum of angles of a triangle is 180  degrees.

Therefore,

angle A + angle B + angle C = 180°

In the given picture two angles are given and we have to find out the third angle.

x° + 45° + 98° = 180°

x° + 143° = 180°

x° = 180° - 143°

x° = 37°

The value of x in the triangle shown is 37°.

Answer:

42

Step-by-step explanation:

We know that in the triangle, there are 3 values. 2 of them are y and 1 of them is unknown.

So, in order to find the value of the unknown number, they gave us an angle supplementary to the unknown.

Supplementary angles are angles that add up to 180 degrees. So the equation for that would be x+88=180.

By subtracting from both sides, we get x=92. So, the unknown angle is 92.

To solve for y, we have to do the same thing, but since we have 2 y's the equation will be 2y+92=180. (92 is the interior angle, aka the unknown one)

Solve:                                            -92 -92

                                                      2y=88

                                                      /2   /2

                                                       y=42

Hence, y is equal to 42.

Step-by-step explanation:

F = 36

G = 4

We know that The area is multiplied by the scale factor squared

F * (SF) ^2 = G

36 (SF) ^2 = 4

Divide each side by 36

36/36 (SF) ^2 = 4/36

(SF) ^2 = 1/9

Take the square root of each side

sqrt((SF)^2) = sqrt(1/9)

SF = 1/3

Answer:

Finding the volume of a cylinder is similar to finding the volume of a prism because they share the same formula, that is:

V = base area x height

Hope this helps!

Answer:

Volume of a prism is base area × height

Base of a cylinder is a circle,

Base area = pi× r²

Volume of cylinder = pi × r² × h

Answer:

d = 52

Step-by-step explanation:

The two angles form a straight line so they are supplementary

Supplementary angles add to 180

d+128 = 180

Subtract 128 from each side

d+128-128 = 180-128

d = 52

Answer:

52

Step-by-step explanation:

so to solve this one, you have to get the value of d.

for this you need to first subtract the given angle from 180.

180-128=52

that is the value of d :) if u need any more help post a question, ill follow you!

Answer:These techniques for elimination are preferred for 3rd order systems and higher.  They use "Row-Reduction" techniques/pivoting and many subtle math tricks to reduce a matrix to either a solvable form or perhaps provide an inverse of a matrix (A-1)of linear equation AX=b.  Solving systems of linear equations (n>2) by elimination is a topic unto itself and is the preferred method.  As the system of equations increases, the "condition" of a matrix becomes extremely important.  Some of this may sound completely alien to you.  Don't worry about these topics until Linear Algebra when systems of linear equations (Rank 'n')  become larger than 2.

Substitution is the preferred method for 2 equations in 2 unknowns.  The constants are unimportant other than having a non-zero determinant.  It is always easy to find multiplicative factors using LCMs of one variable or the other to allow substitution into the other equation:

Example:

4X + 5Y = 9

5X -  4Y = 1

Notice that 20 is a LCM of either the X or Y variable.  So multiply the first by 4 and the second by 5 and then adding the two (Y's will drop out allowing for substitution)

4(4X + 5Y = 9)

5(5X -  4Y = 1)  

Multiplying to produce the LCM factors:

16X + 20Y = 36

25X -  20Y = 5

Adding the equations

41X = 41

X = 1

Substitution into either equation yields

Y = 1
