what is ????????????

Answer:

990, C

Step-by-step explanation:

The formula for the surface area of the bottom cushion is

A = 2wl + 2lh + 2hw (w is width, l is length, h is height)

w = 18, l = 21, h = 3

A = 2(18)(21) + 2(21)(3) + 2(3)(18)

A = 2(378) + 2(63) + 2(54)

A = 756 + 126 + 108

A = 990 (C)

Answer:

A

Step-by-step explanation:

The line plot is obviously symmetric because if you fold it, you would get a perfect fold. It is not bell shaped because, well, it's not in the shape of a bell. It just creates a straight line of points. This just makes option A the only logical answer.

Best of Luck!

Answer:

[tex] \sqrt{41} [/tex]

Step-by-step explanation:

d=√((x_2-x_1)²+(y_2-y_1)²

lets solve

[tex] d= \sqrt{ (- 4-1)²+(1 + 3)²} [/tex] after solving this equation we will find it equal to root 41

Answer: 207

Step-by-step explanation:

To find the surface area, find the area of all the shapes in the three-dimensional figure and then add them.

Find the area of the two triangles first:

1/2*b*h = area of a triangle

1/2* 8* 9= 36

36 is the area of one of the triangles.

Multiply 36 by two because there are two triangles.

=72

Then find the area of the squares/rectangles.

8*5= 40

9*5= 45

10*5 = 50

72+40+45+50

=207

Answer:

A. -1/4

Step-by-step explanation:

The line is going down making the slope negative and doing rise over run the slope is -1/4.

[tex]\frac{1- 0}{0-4}[/tex]= 1/-4 = -1/4

Uhh... what are the options?

Here's some possible ones:

The required graph B shows the data points that move upward direction and are located at 0 and 2, 1 and 3, 2 and 4, 3 and 5, 4 and 6, 5 and 7, 6, and 8, 7 and 9. Option B is correct.

Graphs have been shown below, the graph with the positive linear association between x and y to be determined.

The graph is a demonstration of curves that gives the relationship between x and y-axis.

Options C and D can be omitted first because question asked for positive linear association between x and y, but in both graphs have negative associations so both options are incorrect.
While Option A and B have a positive association but graph A does not have a linear association so graph A will also be omitted. Graph B has a linear association because a straight curve represents linearity.

Thus, the required graph B shows the data points that move upward direction and are located at 0 and 2, 1 and 3, 2 and 4, 3 and 5, 4 and 6, 5 and 7, 6, and 8, 7 and 9. Option B is correct.

Answer:

Equation: (2x+5)4=(2x+8)3

X: 2

Perimeter: 36

Step-by-step explanation:

You would multiply 2x+5 and 4 because there are four sides to a square, so the perimeter of the square would be 8x+20. This would go same for the triangle, making the perimeter 6x+24.

So 8x+20=6x+24 is your new equation. Then, you do the opposite of the order of operations, and add or subtract first. It would be easiest to subtract 20 and 6x from both sides.

That leaves you with 2x=4. Dividing 2 by both sides means x=2

You can plug this in to prove if it is correct.

16+20=36

12+24=36

Answer:

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.
