Answer: Rachel is 30 years old and Kayla is 18

Step-by-step explanation:

I got the answer like this:

What plus what equal 48. 24 + 24

So to get the answer I subtracted one from the first 24, and added one to the second 24.

I did this until they were 12 numbers away. This gave me their age.

Step-by-step explanation:  Chemical signal is the type of communication which coordinates actions between neighboring cells . This ability originated in single cells organisms and was essential for the evolution of multicellular organisms because after a cell receives a message, it is transferred across the plasma membrane and changes are brought about within the cell in response to this message.

Step-by-step explanation:

= -6m+b

2= -2m+b

2= -4m

m= -0.5 = -1/2

4= -6m+b

b= 4+6(-0.5)= 4-3=1

y=mx+b

y= -1/2 x + 1

Answer:

  90°

Step-by-step explanation:

Any corner angle in a rectangle is 90°. Rotating the figure does not change that. Angle O' = 90°.

_____

Additional comment

No rigid transformation (translation, rotation, reflection) changes any angles. Nor does uniform dilation (the kind we usually study). Hence any rectangle that is translated, rotated, reflected, or dilated will still have all angles measuring 90°.

The answer vary but let use 9 and 8.

Step-by-step explanation:

First, let write this equation down.

[tex] {x}^{2} + 6x + c[/tex]

In order to factor this expression, we must think of two numbers that can add to 6, but Also multiply to C. This number vary but let use two potential scenarios

Let use 3 and 3 since 3+3=6 to find C let multiply 3 and 3.

3x3=9.

So one value of C could be 9.

This expression factor equal

[tex](x + 3) {}^{2} [/tex]

Let use another one.

Since 2 and 4 add to 6. Let multiply 2 and 4 to find C.

[tex]2 \times 4 = 8[/tex]

So c=8

Thus expression factor equal

[tex](x + 2)(x + 4)[/tex]

Answer:

[tex]x^4 - 81 = (x - 3)(x+3)(x^2 + 9)[/tex]

Step-by-step explanation:

Given

[tex]x^4 - 81[/tex]

Required

Write an equivalent expression

Express 81 as 9^2

[tex]x^4 - 81 = x^4 - 9^2[/tex]

Express x^4 as (x^2)^2

[tex]x^4 - 81 = (x^2)^2 - 9^2[/tex]

Apply difference of two squares:

[tex]x^4 - 81 = (x^2 - 9)(x^2 + 9)[/tex]

Express 9 as 3^2

[tex]x^4 - 81 = (x^2 - 3^2)(x^2 + 9)[/tex]

Apply difference of two squares

[tex]x^4 - 81 = (x - 3)(x+3)(x^2 + 9)[/tex]

Hence, an equivalent expression is: [tex](x - 3)(x+3)(x^2 + 9)[/tex]

Answer:

a=-19/7, b=5/7

Step-by-step explanation:

Answer:

Step-by-step explanation:

I think you meant [tex](\sqrt5+\sqrt3)\div(\sqrt5-\sqrt3)[/tex]

Then:

        [tex](\sqrt5+\sqrt3)\div(\sqrt5-\sqrt3)=\dfrac{\sqrt5+\sqrt3}{\sqrt5-\sqrt3}\cdot\dfrac{\sqrt5+\sqrt3}{\sqrt5+\sqrt3}=\\\\\\=\dfrac{(\sqrt5)^2+2\cdot\sqrt5\cdot\sqrt3+(\sqrt3)^2}{(\sqrt5)^2-(\sqrt3)^2}=\dfrac{5+2\sqrt{15}+3}{5-3}=\dfrac{8+2\sqrt{15}}{2}=\\\\\\=\dfrac{2(4+\sqrt{15})}{2}=4+\sqrt{15}\\\\\\a=4\,,\qquad b=-1[/tex]

Answer:

y = 3x - 7

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = 3 , then

y = 3x + c ← is the partial equation

To find c substitute (4, 5) into the partial equation

5 = 12 + c ⇒ c = 5 - 12 = - 7

y = 3x - 7 ← equation of line

Answer:

43. [tex]= \frac{.0045}{100}[/tex]

44. [tex]4\frac{9}{10}[/tex]

45. 8

Step-by-step explanation:

43. 0.45% = .0045

      [tex]= \frac{.0045}{100}[/tex]

44. [tex]\frac{1}{2}[/tex] • [tex]9\frac{4}{5}[/tex]

Answer:

Steve can buy 25 songs with his gift card.

Step-by-step explanation:

Money with Steve = $ 100

Money per song = $ 3.99

No. of songs Steve can buy =?

No. of songs Steve can buy = Money with Steve ÷ Money per song

No. of songs Steve can buy = $100 ÷ $3.99 (round off 3.99 to 4)

= 100 ÷ 4

= 25 songs.

Answer:

1. 30 student

2. 120 student's didn't vote

3. 7 quarters

Step-by-step explanation:

1. first, see how many games can be played:

45÷3 = 15

then, multiply the number of games by two because 2 students can play per game

15 • 2 = 30

2. first, figure out what percent of students did not vote:

  100 - 60 = 40%

  then, multiply the number of students total (300) by the decimal of the percent that did not vote to find the number of students who didn't vote:

    300 • .40 = 120 student's didn't vote

3. first, find how much 9 dimes is:

   1 dime = $0.10

   9 dimes = 9 • $0.10 = $0.90

  then, find how much money kerry had:

   $2.65 - $0.90 = $1.75

   finally, find out how many quarters kerry had by dividing the amount of money she had by the worth of a quarter:

   1 quarter = $0.25

    $1.75 ÷ $0.25 = 7 quarters
