Answer:

  24

_______

2r^3 - 12r

Step-by-step explanation:

Let's solve for a.

24 = a(−2r^1)(6 − r^2)

Step 1: Flip the equation.

2ar^3 − 12ar = 24

Step 2: Factor out variable a.

a(2r^3 − 12r) = 24

Step 3: Divide both sides by 2r^3 - 12r.

a(2r^3 − 12r)            24

__________ = ________

   2r^3 - 12r       2r^3 - 12r

Answer:

B. A (1, −2) → A ′(−4, −1) → A ″(−1, −1)

Step-by-step explanation:

When you see anything in between <> (let's say <a, b> are the numbers), it basically means <x+a, y+b>.

So if you replace a with -5, b with 1, and x and y with (1, -2) you get...

= (1 + (-5), -2 + 1)

= (1-5, -1)

= (-4, -1) ----------> Those are the coordinates of the new point.

But wait, it says that we now have to translate along the vector <3, 0>

So (-4, -2) become the new (x, y) coordinates and <3, 0> become the new a, b

= (-4+3, -1 + 0)

= (-1, -1)

That means that the coordinates of point A'' are (-1, -1)

Another way you could do this is by combining the two translations to just do one translation. It'll skip over the middle step, but will still give you the correct answer.

You would combine them by adding the translations of the x-coordinates together and the y-coordinates together

= <-5 + 3, 1 + 0 >

= <-2, 1>

Now you translate the point by this vector and...

= (1 - 2, -2 + 1)

= (-1, -1)

Tada! It works!

Therefore, the answer is B.

Answer:

A). X is 80 degrees

Step-by-step explanation:

B). We know this because AD and EH are congruent.  Since B and F are also congruent, then x and the angle above B must be congruent. So, the angle an=bove B is 80 degress, which makes line AD 180 degrees, or a straight line. that must mean that x is 80 degrees as well.

I hope this works. Good luck!

Answer:

MAD mean absolute deviation = 18.9

Step-by-step explanation:

mean: 26 + 34 + 66 + 71 + 76 + 82 + 88 + 95 = 538/8 = 67.25

26 - 67.25 = 41.25

34 - 67.25 = 33.25

66 - 67.25 = 1.25

71 - 67.25 = 3.75

76 - 67.25 = 8.75

82 - 67.25 = 14.75

88 - 67.25 = 20.75

95 - 67.25 = 27.75

(MAD) mean absolute deviation: 41.25 + 33.25 + 1.25 + 3.75 + 8.75 + 14.75 + 20.75 + 27.75 = 151.5/8 = 18.9

Answer:

a > -15b

Step-by-step explanation:

3a + 7b > 2a – 8b

3a - 2a > - 8b -7b

a > -15b

The value of is as follows:

a > -15b

3a + 7b > 2a – 8b

The question wants us to make a the subject of the formula,

Therefore,

3a + 7b > 2a – 8b

subtract 2a from both sides

3a - 2a + 7b > 2a - 2a - 8b

a + 7b > - 8b

subtract 7b from both sides

a + 7b - 7b > - 8b - 7b

a > -15b

Therefore,

a > -15b

Answer:

36 %

Step-by-step explanation:

9 girls = 36%

25 students = 100

Answer:

Step-by-step explanation:

25 students in a class and 16 out of the 25 students in the class are girls. There are 9 boys in the class because "25-9=16"

HOW TO SOLVE If we know that 9 out of the 25 students in the class are girls, we can represent it as the fraction . Next, we divide 35 by 9 to get a quotient of 0.36 and then multiply by 100 to get our percent of girls in the class which is 36%

Answer:

[tex]Total Plants = 4F + 2P + 10L+ 8S[/tex]

[tex]Total Plants = 2(2F + P + 5L+ 4S)[/tex] --- Distributive property

Step-by-step explanation:

Given

Ferns = 4

Palms = 2

Lillies = 10

Shrubs = 8

Required

Show the total cost of plants as an expression

Shorten it using the distributive property

First, represent Ferns with F; Palms with P; Lilies with L and Shrubs with S;

So, 4 Ferns = 4F

2 Palms = 2P

10 Lilies = 10L

8 Shrubs = 8S

Total Plants = Summation of the above parameters

[tex]Total Plants = 4F + 2P + 10L+ 8S[/tex]

The above expression represents the total plants bought;

Now, to apply the distributive property; we simply look for a common factor;

In this case, the common factor is 2;

So, [tex]Total Plants = 4F + 2P + 10L+ 8S[/tex] becomes

[tex]Total Plants = 2(\frac{4F}{2} + \frac{2P}{2} + \frac{10L}{2}+ \frac{8S}{2})[/tex]

[tex]Total Plants = 2(2F + P + 5L+ 4S)[/tex]

Answer:

8 dollars per extra person

Step-by-step explanation:

subtract the original 40 dollars from 80 ,you get 40,the probloem tells you that there is 9 people meaning there was 5 extras ,so 40/5=8

Answer:

$8 charge for each additional person

Step-by-step explanation

$40/night for each person

First 4 people already paid.

Leftover are 5 people.

9-4=5

Since first 4 people paid, the rest to be paid is $40.

$80-$40=$40

To find the charge for each person, divide the amount of money left by the amount of people left.

40÷5= 8

$8 is the additional charge for each additional person.

Answer:

the parabola can be written as:

f(x) = y = a*x^2 + b*x + c

first step.

find the vertex at:

x  = -b/2a

the vertex will be the point (-b/2a, f(-b/2a))

now, if a is positive, then the arms of the parabola go up, if a is negative, the arms of the parabola go down.

The next step is to see if we have real roots by using the Bhaskara's equation:

[tex]x = \frac{-b +-\sqrt{b^2 -4ac} }{2a}[/tex]

Now, draw the vertex, after that draw the values of the roots in the x-axis, and now conect the points with the general draw of the parabola.

If you do not have any real roots, you can feed into the parabola some different values of x around the vertex

for example at:

x =  (-b/2a) + 1 and x =  (-b/2a) - 1

those two values should give the same value of y, and now you can connect the vertex with those two points.

If you want a more exact drawing, you can add more points (like x =  (-b/2a) + 3 and x =  (-b/2a) - 3) and connect them, as more points you add, the best sketch you will have.

Answer:

D) Addition property of equality and division property of equality

Step-by-step explanation:

Step(i):-

Given equation 3 x -6 =12

Apply addition property of equality

Adding '6' on both sides , we get

                       3 x - 6 + 6 = 12 +6

                       3 x  = 18

Step(ii):-

Apply Division property of equality

Dividing '3' on both sides , we get

                       [tex]\frac{3 x}{3} = \frac{18}{3}[/tex]

on simplification , we get

                      x = 6

Conclusion:-

The solution of the given equation  is x =6

The area of the model on the left is 12[tex]cm^{2}[/tex]

The scale factor is a measure for similar figures, who look the same but have different scales or measures. Suppose, two circle looks similar but they could have varying radii. The scale factor states the scale by which a figure is bigger or smaller than the original figure.

Scale Up (smaller to larger)         = [tex]\frac{Larger figure measurement }{Smaller figure measurement}[/tex]

Scale Down (larger to smaller)     = [tex]\frac{Smaller figure measurement }{larger figure measurement}[/tex]

According to question

area of right triangle which have (1cm= 2inch) is 108 [tex]cm^{2}[/tex] .

and Left triangle  have (1cm= 6inch)

we will convert cm into inch for right triangle

area of right triangle = 108 [tex]cm^{2}[/tex]

 as 1 cm = 2inch

1 [tex]cm^{2}[/tex] = 4 [tex]inch^{2}[/tex]

therefore,

108 [tex]cm^{2}[/tex] = 4 * 108  [tex]inch^{2}[/tex]

as mentioned that  two different models of the same triangular handkerchief

and left triangle is 1 cm = 6 inch

1 [tex]cm^{2}[/tex] = 36 [tex]inch^{2}[/tex]

now we have to scale down as we have to larger to smaller

Scale Down (larger to smaller)    = [tex]\frac{Smaller figure measurement }{larger figure measurement}[/tex]

= 4*108  / 36

= 12

Hence, the area of the model on the left is 12[tex]cm^{2}[/tex]
