Answer:

Surface Area - 122

Step-by-step explanation:

Answer:

A) No, because the greatest common factor is 8y?, and the completely factored form is 8y2(4y2 - 6y + 3).

Step-by-step explanation:

Considering the expression

4y(8y3 – 12y2 + 6y)

From the elements in the parenthesis, 2 and y can still be factored out such that what will be left of each element

8y3/2y = 4y2

12y2/2y = 6y

6y/2y = 3

Hence

4y(8y3 – 12y2 + 6y) = 4y*2y(4y2 - 6y +3)

= 8y2(4y2 - 6y + 3)

Options:

A.) box-and-whisker plot B.) circle graph C) line graph D.) scatter plot

Answer:

Scatter plot

Step-by-step explanation:

The best display from the option which would best represent a good graphical outline of the data is the scatter plot, having to axis ; vertical and horizontal, the vertical axis would represent the amount of donation spent while the horizontal, x - axis would depict the type of expenditure such as research and other which the lab embarked upon with the donated amount. Each point is denoted by a marked point scattered over the graphical area. The research based expenditure will be vertically higher as they incurred higher amount than other type of spending.

Answer: 7th total= 46

more= 28

less=18

8th total= 27

more=15

less=12

both 7th and 8th total= 73

more=43

less=30

Step-by-step explanation:

7th total: it says that 46 7th graders were surveyed so 46 7th graders were surveyed.

7th more: it said that 28 7th graders spent more then a hour so 28 7th graders spent more then an hour on the survey.

7th less: it said the there were 16 7th graders surveyed and 28 7th graders that spent more than an hour on the survey so 46-28=18 so 18 7th graders spent less than an hour on the survey.

8th total: it said 27 8th graders were surveyed so 27 8th graders were surveyed.

8th more: it said 43 students were surveyed more than an hour and that 28 7th graders were surveyed over an hour so you have to subtract 43 by 28, so 43-28=15 so 15 8th graders were surveyed over an hour.

8th less: it said 27 8th graders were surveyed and we found out that 15 8th graders spent over an hour so you have to subtract 27 by 15 so 27-15 is 12 so 12 8th graders spent less than an hour on the survey.

7th and 8th total: it said 46 7th graders were surveyed and that 27 8th graders were surveyed so you have to add 46 and 27, so 46+27=73 so 73 students were surveyed.

7th and 8th more: it said that 43 students were surveyed over an hour so 43 students were surveyed over an hour.

7th and 8th less: we found out that 18 7th graders were surveyed under an hour and 12 8th graders were surveyed under an hour so we have to add 18 and 12, so 12+18=30 so 30 students were surveyed under an hour.

Step-by-step explanation:

It was correct on edge 2021

The equation that is correct regarding the measure of <MNP is 1/2(x-y)

In order to determine the measure of m<MNP, we will use the theorem shown below;

The angle at the vertex is half the difference of angles at the intercepted arcs.

The angle at the vertex = m<MNP

angle a the arcs are x and y

Hence;

m<MNO = 1/2 (x - y)

Hence the equation that is correct regarding the measure of <MNP is 1/2(x-y)

Which is the percentage that we have to pay for and how we can go about this one on our own in as the following

9514 1404 393

Answer:

  see attached

Step-by-step explanation:

The transformations are ...

  (x, y) ⇒ (-y, x) . . . . 90° rotation

  (x, y) ⇒ (-x, -y) . . . . 180° rotation

  (x, y) ⇒ (y, -x) . . . . 270° rotation

Each successive rotation is a 90° rotation from the previous one. This makes writing the formulas in a spreadsheet really easy. The attached shows the transformed coordinates.

Step-by-step explanation:

1. Approach

To solve a system by the process of elimination, one wants to manipulate an equation such that when one adds the equations in a system, one of the variables cancels out. The easiest way to do this is to select a variable, then find the LCM (least common multiple) of the two coefficients of the selected variables. Then multiply each of the equations by the respect factor that is needed to get the coefficient of the variable to the LCM. In the event that the cofficients do not have inverse signs, multiply one of the equations by (-1). No all that is left is to add the equations, use inverse operations to solve for the other variable, then back substitute to find the value of the selected varibale.

2.Set up the process

3x - 2y = 2

5x - 5y = 10

Selected variable; x

LCM of the coefficents (3, 5) = 15

Multiply the first equation by 5, and the second by 3

(3x - 2y = 2) *5

(5x - 5y = 10)*3

Resulting system

15x - 10y = 10

15x - 15y = 30

Now, multiply the first equation by (-1) to make the coefficents additive inverses

(15x - 10y = 10) (-1)

15x - 15y = 30

-15x + 10y = -10

15x - 15y = 30

3. Solving

Add the two resulting systems,

-15x + 10y = -10

15x - 15y = 30

_____________

-5y = 20

Inverse operations

-5y = 20

/-5        /-5

y = -4

Back solve

3x - 2y = 2

(3x) - 2(-4) = 2

Simplify,

3x + 8 = 2

Inverse operations,

3x + 8 = 2

    -8      -8

3x = -6

/3   /3

x = -2
