Answer:

Sophia now has 39 cents.

Step-by-step explanation:

One quarter = 25 cents

Since Sophia had 64 cents until she spent 25 cents (1 quarter).

So we subtract 25 cents from 64 cents.

[tex] \: \: \: 64 \: cents \\ \frac{ - 25 \: cents}{ \: \: \: 39 \: cents} [/tex]

Therefore, Sophia now has 39 cents.

Answer:

x = 4/25

Step-by-step explanation

Amount of tangerines in bags sold = 25kg

If a customer bought 4kg of tangerines, the number of bags he bought is expressed as x;

4 kg = x bags

25 kg = 1 bag

Cross multiply

25 x = 4 * 1

25x = 4

Divide both sides by 25

25x/25 = 4/25

x = 4/25

Hence the required equation is x = 4/25

Answer:

So if you are in middle school like me, they are asking for an equation answer, and that equation is 4 divided by 2/5 = _ and _ x 2/5 = 4

Answer:

1248' x 2056' so I think you missed copying decimals but I would asume B

Step-by-step explanation:

312''x(1/(1/4''))=1248'

514''x(1'/(1/4''))=2056'

The dimensions in feet's are 1248' x 2048'.

We have architectural drawing scale -  1' = 1/4"

We have to convert the dimensions 312" by 514" into feet's.

double prime (″) is symbol for inches.

single prime (') is a symbol for foot(singular)/ feet's (plural)

1 foot =12 inches.

According to the question -

1' = 1/4"

1 foot = 1/4'' inches

Then, 1 inches will have = [tex]\frac{1}{\frac{1}{4} }[/tex] = 4 feet's.

Therefore -

312" = 312 x 4' = 1248 feet's

514" = 512 x 4' = 2048 feet's

Hence, the dimensions in feet's are 1248' x 2048'.

Answer:

Number of month = 25 month

Step-by-step explanation:

Given:

Plan A $70 per month and $500 phone cost

Plan B $50 per month No phone

Assume;

Number of month = x

So,

50x + 500 = 70x

20x = 500

x = 25

Number of month = 25 month

Answer:

-543

Step-by-step explanation:

For every value of k, you substitute 9 and for every value of c, you substitute 2

-6((8x(9)+ 9(2)) - 3

so order of operations says you should do what's in the parentheses first.

8 x 9= 72     and 9 x 2 = 18

so now you have -6 ( 72 + 18) -3

Finish the calculating inside the parentheses:   -6 (90) -3

and now multiply -6   and 90 before you subtract 3

-6 x 90 = -540

-540 - 3   = -543

Answer:

100 bc 150/3 = 50x2=100 this equation vary on the percent bc if it was 3/3 then u would devide by 3 then times 3 get it?

Answer:

100 students.

Step-by-step explanation:

First because it says "..2 out of 3" you have 2 boxes (i'm using a tape diagram) for the students that prefer gel toothpaste and 1 box for the others/don't prefer gel toothpaste students. Since there are 150 students in the school in total you will divide the number of students (150) by the 3 boxes and get 50. Each box will be filled with 50. Students that prefer gel toothpaste : 50 x 2 = 100 (students) Students that don't prefer gel toothpaste : 50 x 1 = 50 (students).

Hope this made sense somehow lol, i'm not very good at explaining.

The solution after divide (3x² - 14x - 5) by (x - 5) will be (3x + 1).

What is Division method?

Division method is used to distributing a group of things into equal parts. Division is just opposite of multiplications.

For example, dividing 20 by 2 means splitting 20 into 2 equal groups of 10.

Given that;

The expression is,

⇒ Divide (3x² - 14x - 5) by (x - 5)

Now,

Divide (3x² - 14x - 5) by (x - 5) as;

x - 5 ) 3x² - 14x - 5 ( 3x + 1

        3x² - 15x

      -      +

      ------------------

               x - 5

              x - 5

           -      +  

         --------------------

                0

Thus, The solution after divide (3x² - 14x - 5) by (x - 5) will be (3x + 1).

Note: You missed to add some basic information of the perpendicular line or missed the answer options, hence I am solving using a sample equation but it would clear your concept.

Answer:

Please check the attached graph.

Step-by-step explanation:

We know the slope-intercept form of line equation is

[tex]y = mx+b[/tex]

where m is the slope and b is the y-intercept

Given the points

Finding the slope between F(1, 8) and G(-3, -4)

[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]

[tex]\left(x_1,\:y_1\right)=\left(1,\:8\right),\:\left(x_2,\:y_2\right)=\left(-3,\:-4\right)[/tex]

[tex]m=\frac{-4-8}{-3-1}[/tex]

[tex]m=3[/tex]

Thus, the slope of the line FG = m = 3

From the given line, we can also determine the y-intercept 'b' by setting x = 0 and checking the corresponding y value.

i.e. at x = 0, y = 5

Thus, y-intercept b = 5

so substituting m = 3 and b = 5 in the slope-intercept form

y = mx+b

y = 3x+5

Therefore, the equation of line FG will be:

Please check the attached diagram, where the red line represents the line y=3x+5

We know that a line perpendicular to another line contains a slope that is the negative reciprocal of the slope of the other line.

Slope of Perpendicular line = -1/m = -1/3

Thus, any line with the slope m = -1/3 would be the line that will be perpendicular to line FG​

Let say the line with the slope m = -1/3 and y-intercept 2

y = -1/3x + 5

Please check the attached graph, the blue line is representing the perpendicular line y =  -1/3x + 5 to line FG

The graph of both lines is clearly representing that the line y = -1/3x + 5 is perpendicular to line FG.

Answer:

Area: 196

Perimeter: 56

Step-by-step explanation:

1. Pick a side for both length and height and count the distance between the two coordinates (for example VU and UT)

VU = 14

UT= 14

Also important to note here that you don't even need to count the distance for both because since it's a square, all the sides are the same. Only did this to make it easier to understand the next step.

2. Since it's a square, as I said before, all sides are the same. So, you can go ahead and mark WT and VW as 14 as well.

3. To get the area, use the formula base times height.

14 x 14 = 196

4. For perimeter, simply add up all the sides (or multiply 14 by 4 since all are the same)

14+14+14+14=56
