I NEED HELP WITH THIS ( IM IN LIVE ADN I NEED IT DONE TODAY)
all you need to do is explain it.

Answer:

printer A-  36/1.5

printer B-  114/3

printer C-  115/5

first, multiply 1.5 x 10, 3 x 5, and 5 x3

you should get 15 for each.

once you have the denominators all done, multiply the numerators by the value you multiplied the denominator by and you should have your answer.

so all in all, printer B prints the fastest

please mark brainliest

Answer:

2 and 20

Step-by-step explanation:

First how can we get rid of the fraction?

We can multiply -1/2 by 2 to get -1

Next what number do we multiply to get from -1 to -20?

-1x = -20

divide both sides by -1

x = 20

please give thanks by clicking the heart :)

Answer:

l=25 cm

Step-by-step explanation:

The perimeter of a rectangle

2(l+w)=70 cm

(l+10)=70/2

l=35-10

l=25

Note : you have no question. So I just assume it

20

Thanks for the support the finals always have been a struggle! Merry Christmas and good luck on everyone's finals!

Answer:

89.10 / 4.95 is 18. so the first one is 18.

6 and 9, so we have to find the LCM. 6,12,18 and 9,18, so the first one to get a red and blue cap is the 18th bottle.

We know that the 18th bottle will get a red and blue, so then we have to find the LCM of 18 and 10. 18,36,54,72,90  10,20,30,40,50,60,70,80,90.

The first one to get all three is  the 90th bottle.

Hope this helps plz hit the crown :D

Answer:

Step-by-step explanation:

This is a difference of squares.

√x^2 - √49  is the basic formula for factoring a difference of squares. The  idea is that the middle term has been cancelled out.

√x^2 = x

√49 = 7

(x - 7)(x + 7) is the way this factors.

(x - 7)(x + 7)

===========

(x + 7)

The (x +7) in the numerator cancels with the (x + 7) in the denominator.

The answer is (x - 7)

====================================================

She might have wanted you to do it like this.

(x + 7) || x^2  + 0x    - 49  || x     -   7

            x^2 + 7x  ........... Subtract

           ==========

                   -7x      - 49

                   -7x      - 49   ...... Subtract.

                   =============

                           0

Or she might have seen you do this

x^2 - 49          x^2        49

=======   =   ===    -   =====

x + 7                x             7

Every math teacher freaks when they see this. I hope I didn't put ideas in your head.

But if you got the answer by doing what I did, you got it right.  

Answer:

determinant formula looks like  ad - bc in a 2 x2 matrix when it's in the from of

a b

c d

as the one is here

Step-by-step explanation:

5*2 - (-4*8)

=10 - (-32)

=10 + 32

= 42

Answer:

Please check the explanation.

Step-by-step explanation:

Given the function

Putting all the values of y=9, 6, 0, and -3 to complete the table

FOR y=9

putting y=9

switch sides

subtract 3 from both sides

Hence,

when y=9, x=4

FOR y=6

putting y=6

switch sides

subtract 3 from both sides

Hence,

when y=6, x=2

FOR y=0

putting y=0

switch sides

subtract 3 from both sides

Hence,

when y=0, x=-2

FOR y=-3

putting y=-3

switch sides

subtract 3 from both sides

Hence,

when y=-3, x=-4

Hence, the table becomes:

x                     y

9                    4

6                    2

0                    -2

-3                   -4

The rule states that

[tex](a^b)^c = a^{bc}[/tex]

So, in your case, you have

[tex](9^{\frac{1}{2}})^2=9^{\frac{1}{2}\cdot 2}=9^1=9[/tex]

Answer: 3.75 + - 7

Step-by-step explanation:

Step-by-step explanation:

Answer:

Step-by-step explanation:

cm= (K2-15) in cm = (10k +9) in

K2 - 15 = 10k + 9

K2 - 10k = 9 + 15

K2 - 10k = 24

2k - 10k = 24

-8k = 24

k = - 3

Answer:

35, 35, and 50

Step-by-step explanation:

50 + x + x = n

n ÷ 3 = 40

n = 40 x 3

n = 120

50 + 2x = n

50 + 2x = 120

2x = 120 - 50

2x = 70

2x/2 = 70/2

x = 35

To check:

35 + 35 + 50 = 120

120 ÷ 3 = 40

Hope this helps

Answer:

35

Step-by-step explanation:

let us take each boy's weight as x

therefore,

average = [tex]\frac{x+x+50}{3\\}[/tex]

40 = [tex]\frac{x+x+50}{3\\}[/tex]

40 x 3 = x + x + 50

120 - 50 = 2x

70 = 2x

2x = 70

x = [tex]\frac{70}{2}[/tex]

x = 35

So weight of each boys is 35.

Answer:

1). x = 14

2). y = 2.4 cm

Step-by-step explanation:

In the diagram ΔNPQ ~ ΔNLM and NL = 3,

1). ∠P ≅ ∠L [All angles of similar triangle are equal in measure]

   (3x + 18)° = 60°

   3x = 60 - 18

   x = 14

2). Since, both the triangles are similar, corresponding sides will be proportional.

   [tex]\frac{PN}{NL}=\frac{NQ}{NM}[/tex]

   [tex]\frac{y}{3}=\frac{3.2}{4}[/tex]

   y [tex]=\frac{3.2\times 3}{4}[/tex]

   y = 2.4 cm

Answer:

that means that the letter p in the equation equals to 500

Answer:

Plz Brain -list the answer  It takes effort tnx dear

Step-by-step explanation:

From given condition

equation of line is given as,

x*cos(α)+y*sin(α)=p

& as tanα= 5/12 so from Pythagoras theorem

sinα=  5/13

​cosα=  12/13

⇒12x+5y=39

p = 3, α = tan-1 (5/12) So, tan α = 5/12 sin α = 5/13 cos α = 12/13 The equation of the line in normal form is given by By using the formula, x cos α + y sin α = p Now, substitute the values, we get 12x/13 + 5y/13 = 3 12x + 5y = 39 ∴

Answer:

option 3

Step-by-step explanation:

Answer: 10 hours

Step-by-step explanation:

First and foremost, we should note that:

Speed = Distance / Time

Total destination = 610 miles

Loretta speed = 55 mph

Time to be used by Loretta = 4 hours

Loretta's distance = Speed × Time = 55 × 4 = 220 miles

The distance to be covered by her dad will then be:

= 610 - 220

= 390 miles

Her dad's average speed = 65 mph.

Time taken by her dad will be:

= 390 / 65

= 6 hours

The number of hours to be used by the family will then be:

Time taken by Loretta + Time taken by her dad

= 4 hours + 6 hours

= 10 hours

Answer:

C. y = 10x + 25

Step-by-step explanation:

If John put $10 each week but we don't know how many weeks that he deposits $10, use x as the amount of weeks. x10.

There was already $25 in his savings account so we don't have to put an x next to the $25.

Answer:

c

Step-by-step explanation:

Step-by-step explanation:

Since angles in the same segment are equal, Angle ABC (x) = Angle AOC.

Since Angles AOC and COD are supplementary, Angle AOC = 180° - 130° = 50°

Therefore x = 50°.

Answer:

4 more hours.

Step-by-step explanation:

So, to calculate the remaining time Jill has to drive, we have to first find out how much distance Jill has left to cover:

[tex](450 - 250)[/tex] miles

= [tex]200[/tex] miles

So, at a rate of 50 miles per hour, Jill has to drive:

[tex]\frac{200}{50}[/tex] more hours

= [tex]4[/tex] more hours
