please help me with this problem about factoring.

Answer:

1-    10% of -80 is -8.  

2-    28 is 4% of 700.

3-   25% of a number is equal to 1/4 or 0.25 of it.

4-    13% of a number is equal to 0.13 of it.

5-    15 is 12.5% of 120.

Step-by-step explanation:

1. 10% of ________- 8

2.28 is 4% of _________

3.25% of ________

4.13% of______

5.15 is 12.5% of _____

To determine the missing numbers in the statements, the following calculations must be performed:

1-

10 = -8

100 = X

100 x -8 / 10 = X

-800 / 10 = X

-80 = X

Therefore, 10% of -80 is -8.

two-

4 = 28

100 = X

100 x 28/4 = X

2800/4 = X

700 = X

Therefore, 28 is 4% of 700.

3-

25% of a number is equal to 1/4 or 0.25 of it.

4-

13% of a number is equal to 0.13 of it.

5-

12.5 = 15

100 = X

100 x 15 / 12.5 = X

1500 / 12.5 = X

120 = X

Therefore, 15 is 12.5% of 120.

Answer:

A number is written in scientific notation when there is a number greater than or equal to 1 but less than 10 multiplied by a power of 10.

If we have a number greater than 10, we move the decimal point to the left until we have a number between 1 and 10. ...

Answer:

5x5x5x5x5x5

Step-by-step explanation:

Hi!

So to find out the slope, we can use the equation change in y value over change in x value -- or vertical change over horizontal change.

Find two points on the graph that line up exactly on the lines of the graph, like (20, 0) and (12, 0).

Then, take the change in y value (20-0 = 20) and divide it by the change in x value (0 - 12) to get -20/12, or -5/3.

Hope this helped!!

Answer:

The dependent variable is speed of typing; the independent variables are the keyboard design and the chime.

Step-by-step explanation:

The variable which we intend to measure or determine is called the dependent or predicted variable. However, to predict or measure the dependent variable, one or more variables are required, these are the variables whose different values or input affects the outcome of the dependent variable, these variables are called the independent variable.

In the scenario described above, the dependent variable is typing speed as it is the variable we intend to measure or determine using the new keyboard design and chime as the predictor variables.

Answer:  No two students ran same distance

Step-by-step explanation:

Given

Stacy ran [tex]\frac{9}{12}[/tex] of a km i.e.

[tex]\Rightarrow 1\times \dfrac{9}{12}=\dfrac{3}{4}=0.75\ km[/tex]

Jules ran [tex]\frac{4}{5}[/tex] of a km i.e.

[tex]\Rightarrow 1\times \dfrac{4}{5}=0.8\ km[/tex]

Raul ran [tex]\frac{3}{4}[/tex] of mile i.e.

[tex]\Rightarrow 1\times \dfrac{3}{4}=0.75\ miles\\\\\text{1 mile=1.6 km}\\\\\Rightarrow 0.75\ miles=1.2\ km[/tex]

So, no two students ran the same distance.

answer:

a function

step-by-step explanation:

hello there!

as you said, there is only able one output ( y ) for each input ( x ) for it able to become a function

here is a little example of a "table" to help me explain this a little better for you!

input ( x ) | output ( y)

      8       |       -3

      3       |       8

      9       |       4

     -2       |       2

since none the inputs have more then one output then that means it is a function

hope this helps you and please let me know if i had made a mistake in the problem, have a wonderful day!! :D

Answer: 163 students

Step-by-step explanation:

First find the percentage of students who were in favor of having school  start one hour later based on the sample of 20 students.

= 13/20 * 100%

= 65%

The apply this percentage to the total number of students in school to find your answer:

= 65% * 250 students

= 162.5

= 163 students

The number of students in the school who are in favor of having school start one hour later is; C: 163 students

We are told that 13 out of the 20 surveyed students were in favour of having school start one hour later. Thus;

Probability = 13/20 * 100% = 65%

Now, the school has 250 students and as such, the number of students in the school who are in favor of having school start one hour later is;

65% * 250 students = 162.5 ≈ 163 students

Answer:

Step-by-step explanation:

Total members in the choir = 24 + 36 = 60

a) Percentage of men = [tex]\frac{24}{60}*100[/tex]

                                 = 4 * 10  = 40%

b) Percentage of women = 60%

c) Number of men =24 + 10 = 34 men

Number of women = 36 + 10 = 46

Total = 34 + 46 = 80

Percentage of men = [tex]\frac{34}{80}*100= 42.5[/tex]%

Percentage of women = (100 - 42.5)% = 57.5%

Answer:

a]

% of men = 24/60 × 100

% of men = 4/10 × 100

% of men = 4 × 10

% of men = 40%

b]

% of women = 36/60 × 100

% of women = 6/10 × 100

% of women = 6 × 10

% of women = 60%

c]

Men = 24 + 10 = 34

Women = 36 + 10 = 46

Total = 34 + 46 = 80

% of men = 34/80 × 100 = 42.5

% of women = (100 - 42.5) = 57.5 %

you know that your line is perpendicular to the line with equation y equals 3x + 5 right whenever a line is perpendicular to another perpendicular not parallel to the line has a negative slope of the other line for example if you had a line with slope 2 x in the line perpendicular to that would have slope -1 / 2X so then you line in your question has slope -1 / 3 x by doing the Rococo of 3 and adding a negative sign to your equation sulfur looks like this y equals negative 1 / 3 x + B where is B is a constant 3 all you have to do is solve for b is a plug in the coordinate values 6 equals x minus -2 equals one in rearrange y equals -1 / 3 x + B negative two equals negative one over three 6 plus b negative two equals negative two plus be there for me easy roast F4U equation of the line is y equals -1 / 3 x
