I need help with this question, I attached a file, so it’s easier to read.

Answer:

  {-15, -5}

Step-by-step explanation:

The constant on the left needs to be the square of half the x-coefficient:

  (20/2)^2 = 100

To get it to that value, we can add 18 to both sides of the equation:

  x^2 +20x +100 = 25 . . . add 18 to both sides of the equation

  (x +10)^2 = 25 . . . . . . .  . write the left side as a square

  x +10 = ±√25 = ±5 . . . . . take the square root

  x = -10 ±5 = {-15, -5}

The solutions are x = -15 and x = -5.

Answer:

m=-44

Explanation: distribute the negative and add -1/4 to m and then take the 5 away from 16 and then multiply both sides

Answer:

M = - 44

Step-by-step explanation:

You will start by subtracting 5 on both sides of the equation.

- (1/4)m + 5 =16

            -5     -5

Simplify

- 1/4 m =11

Multiple both sides by - 4

(-1/4m)(-4)= 11 (- 4)

The final result is m equals negitive 4.

M = -44

Step-by-step explanation:

Step 1:  Subtract 87 from both sides

[tex]2x^2 - 11 - 87 = 87 - 87[/tex]

[tex]2x^2 - 11 - 87 = 0[/tex]

Step 2:  Factor

[tex]2x^2 - 11 - 87 = 0[/tex]

[tex]2(x + 7)(x - 7) = 0[/tex]

[tex]x + 7 = 0[/tex] and [tex]x - 7 = 0[/tex]

[tex]x = -7[/tex] and [tex]x = 7[/tex]

Answer:  [tex]x = -7, 7[/tex]

Answer:

x = 7, -7

Step-by-step explanation:

2x² - 11 = 87

2x² = 98

x² = 49

x = +/-7

Answer:

Direct materials

Step-by-step explanation:

In this case we must bear in mind that as more products are sold, more material is needed to manufacture those additional final products

.

Therefore, in this case the cost would be related mainly to the materials, mainly the direct materials, since they are essential in the production of the product.

Answer:

Tina could make are 10 Possible total points.

They number of possible total points are; 18, 19, 20, 21, 22, 23, 24, 25, 26 and 27.

Step-by-step explanation:

This is a zero-sum sort of deal. If tina makes 9 baskets, they can be all 2 points or all 3 points.

Let's make some number of 2 points "n". Then, the number of 3 points has to be 9 - n. The logic is exactly the same if we considered the number of 3 points made to be "n".

Thus, the maximum of this relationship is when n = 0.

Hence, 9 baskets gives the following possible permutations:

1) 0 number of 2 points and 9 number of 3 points = 27 points

2) 1 number of 2 points and 8 number of 3 points = 26 points

3) 2 number of 2 points and 7 number of 3 points = 25 points

4) 3 number of 2 points and 6 number of 3 points = 24 points

5) 4 number of 2 points and 5 number of 3 points = 23 points

6) 5 number of 2 points and 4 number of 3 points = 22 points

7) 6 number of 2 points and 3 number of 3 points = 21 points

8) 7 number of 2 points and 2 number of 3 points = 20 points

9) 8 number of 2 points and 1 number of 3 points = 19 points

10) 9 number of 2 points and 0 number of 3 points = 18 points

So the number of possible points Tina could make are; 18, 19, 20, 21, 22, 23, 24, 25, 26 and 27.

Answer:

Option c. 5.7 grams

Option b. 5.3 grams

Step-by-step explanation:

(a) A [tex]4\frac{1}{2}[/tex] ounce hamburger patty has [tex]25\frac{1}{2}[/tex] grams of protein.

first we convert mixed fraction to improper fraction.

Amount of protein a  [tex]\frac{9}{2}[/tex] ounce hamburger patty has = [tex]\frac{51}{2}[/tex] grams

∴  Amount of protein a 1 ounce hamburger patty has = [tex]\frac{\frac{51}{2} }{\frac{9}{2} }[/tex]

= [tex]\frac{51}{2} \times \frac{2}{9}[/tex]

= [tex]\frac{51}{9}[/tex]

= [tex]\frac{17}{3}[/tex] = [tex]5\frac{2}{3}[/tex] = 5.7 grams

(b)  A 6 ounces of fish has 32 grams of protein.

∴ The amount of protein a 1 ounce of fish has = [tex]\frac{32}{6}[/tex]

                                                                            = 5.3 grams

A hamburger patty has approximately 5.7 grams of protein per ounce.

A fish has approximately 5.3 grams of protein per ounce.

Formula: r = C/2π

Solve with the given values.

r = 452.16/2(3.14)

r = 452.16/6.28

r = 72

Therefore, the radius is approximately 72 units.

Answer:

25

Step-by-step explanation:

Answer:

Step-by-step explanation:

Basically, we're solving for a.

w = 3(2a + b) - 4

w = 6a + 3b - 4

-6a + w = 3b - 4

-6a = -w + 3b - 4

a = (w - 3b + 4)/6

Answer:

x^2 + 10x +21

Step-by-step explanation:

Your multiplying the Squares together and then adding them

Blue Square : x*x= x^2

Pink  Square : x*7= 7x

Green Square: x*3= 3x

Orange Square: 3*7= 21

Now we add all the squares together to get the total area.

x^2+7x+3x+21

x^2+ 10x +21

Answer:

3 bars

Step-by-step explanation:

Total no. of gold bars = 24.

Fraction of bar captain allocated to himself = 1/3 of the bars

no. of bars he allocated to himself =  1/3 of 24 = 1/3 * 24 = 8

Fraction of bar captain allocated to his friend bill = 1/4 of the bars

no. of bars he allocated to his friend bill =  1/4 of 24 = 1/4 * 24 = 6

No . of bars captain allocated to rest of crew = 7

Total no of bars which are allocated altogether =

no. of bars he allocated to himself +no. of bars he allocated to his friend bill +No . of bars captain allocated to rest of crew

substituting the value of above summation variable as calculated above we have

Total no of bars which are allocated altogether = 8+6+7 = 21

No. of bars left = total no. of bars - Total no of bars which are allocated altogether = 24 - 21 = 3

Thus 3 gold bars are left.

Answer:

b. the ranges of penguin heights are the same.

Step-by-step explanation:

Hello!

Statements:

Which statement correctly compares the spreads of the distributions?

a. the mode of penguin heights at county side zoo is greater than  the mode at city view zoo.

b. the ranges of penguin heights are the same.

c. the range of penguin heights is greater at city view zoo than at  county side zoo.

d. the range of penguin heights is greater at county side zoo than at  city view zoo.

The mode and mean are measurements of central tendency, these indicate the position of a data set but don't show any information concerning the distribution of said data.

The range on the other had is a measurement of variance, it shows the difference between the maximum and minimum values of the data set and indicates its total dispersion.

City view Zoo R= 44-37= 7 cm

County side Zoo: R= 45-38= 7 cm

Both ranges are the same.
