Answer:

Distributive Property

Step-by-step explanation:

If we have an equation where we multiply something in parentheses by a certain term, then we can apply the distributive property to simplify it.

In this case: [tex]5(x-7)=55[/tex]

We can multiply [tex]x-7[/tex] by 5 to simplify this equation - this is the distributive property.

[tex]5x - 35 = 55[/tex]

So the property used to write the equation in Step 2 was the distributive property.

Answer:

c. 108

Step-by-step explanation:

Given

Shape of container: Cube

Initial dimension of the container = 6ft by 6ft by 6ft

Initial Number of boxes = 4

Required

Calculate the number of boxes when the dimension is tripled

The first step is to calculate the initial volume of the box;

[tex]Volume = Length * Length * Length[/tex]

[tex]Volume = 6ft * 6ft * 6ft[/tex]

[tex]Volume = 216ft^3[/tex]

This implies that the container can contain 4 small boxes when its volume is 216;

Represent this as a ratio;

[tex]4 : 216[/tex]

The next step is to calculate the volume when the dimension is tripled;

[tex]New\ Length = Old\ Length * 3[/tex]

[tex]New\ Length = 6ft* 3[/tex]

[tex]New\ Length = 18ft[/tex]

Hence;

[tex]Volume = 18ft * 18ft * 18ft[/tex]

[tex]Volume = 5832ft^3[/tex]

Let the number of boxes it can contain be represented with x

Similarly, represent this as a ratio

[tex]x : 5832[/tex]

Equate both ratios;

[tex]4 : 216 = x : 5832[/tex]

Convert ratios to fractions

[tex]\frac{4}{216} = \frac{x}{5832}[/tex]

Multiply both sides by 5832

[tex]5832 * \frac{4}{216} = \frac{x}{5832} * 5832[/tex]

[tex]5832 * \frac{4}{216} = x[/tex]

[tex]\frac{5832 *4}{216} = x[/tex]

[tex]\frac{23328}{216} = x[/tex]

[tex]108 = x[/tex]

[tex]x = 108[/tex]

Hence, the maximum number of boxes it can contain is 108

Answer:

third option

Step-by-step explanation:

Given

x² + 4x - 4 = 0 ( add 4 to both sides )

x² + 4x = 4

Using the method of completing the square

add ( half the coefficient of the x- term )² to both sides

x² + 2(2)x + 4 = 4 + 4, that is

(x + 2)² = 8 ( take the square root of both sides )

x + 2 = ± [tex]\sqrt{8}[/tex] = ± 2[tex]\sqrt{2}[/tex] ( subtract 2 from both sides )

x = - 2 ± 2[tex]\sqrt{2}[/tex]

You are correct except to the nearest hundredth it is 795.54 cm^2.

Answer: x = 137°

Step-by-step explanation:

When a quadrilateral is inscribed in a circle, the opposite angles are supplementary.

x + 43° = 180°

      x   =  137°

The value of x is 137°.

The quadrilateral whose all 4 vertices lie on the circumference of the circle is called an inscribed quadrilateral.

In inscribed quadrilateral opposite angles are supplementary i.e. sum of those opposite angles is 180°.

Here given in the picture that the measurements of the two opposite angles in the inscribed quadrilateral in the circle are 43° and x°.

So as we know in the inscribed quadrilateral opposite angles are supplementary.

So sum of those opposite angles in the quadrilateral is 180°.

so we can write x+43°= 180°

⇒ x = 180°- 43°

⇒ x = 137°

Therefore the value of x is 137°.

Answer:

B. $35.50/hr and \$6,079.38 in total income

Step-by-step explanation:

Given the following :

Total regular pay earning for the year = $73,840

Let basic salary = b

Overtime = 1.5b

Regular earning per week :

Regular year earning / number of weeks per year

$73840 / 52 = $1420

Regular hours = 40

Regular earning per week = $1420

Regular earning per hour = $1420 / 40

Regular earning per hour = $35.50

Number of overtime hours :

4 hours + 3.5hours = 7.5hours

Overtime pay per hour = 1.5 * regular earning

Overtime pay per hour = 1.5 * 35.5 = $53.25

Total overtime pay = Overtime pay per hour * Number of overtime hours

Total overtime pay = $53.25 * 7.5

Total overtime pay = 399.375

Total pay for the month :

160 regular hours + 7.5 overtime hours

(160 * 35.5) + $399.375

$5,680 + 399.375 = $6,079.375

= $6,079.38

Answer:

Correct question is;

Kermit's favorite iced tea is made with 15 tea bags in every 2 liters of water. Peggy made a 12-liter batch of iced tea with 90 tea bags. What will Kermit think of Peggy's iced tea? Choose 1 answer: (Choice A) A It is too strong.

(Choice B) B It is too weak.

(Choice C, Checked) C It is just right.

Answer:

C - It is just right

Step-by-step explanation:

We are given that;

The Number of tea bags needed to make every 2 liters of water = 15 tea bags.

Thus,

For each liter of water, the number of tea bags needed = 15/2 = 7.5 tea bags.

Now, kermit needs to make 12 liters of iced tea.

Therefore, total number of tea bags required for 12 liters of iced tea = 12 × 7.5 = 90 tea bags.

Now, Peggy also took 90 tea bags to make a 12-liter batch of iced tea.

Therefore, kermit would think that the mixture of Peggy's tea is just right.

Answer:

a) Cost

[tex]C(q) = 50+16q\\\\C(500)=50+16(500)=50+8,000=8,050[/tex]

b) Sales income

[tex]S(q)=20q\\\\S(500)=20\cdot 500 = 10,000[/tex]

c) Table of values

[tex]\left[\begin{array}{ccc}q&C(q)&S(q)\\0&50&0\\250&4,050&5,000\\500&8,050&10,000\end{array}\right][/tex]

d) Attached

e) Breakeven point = 12.5 sheets

f) Profit at 550 sheets = $1,950

Step-by-step explanation:

a) We have a fixed cost for the image, at $50.

We also have a variable cost of $16 a sheet.

The purchased quantity is 500 sheets.

Then, the cost function is:

[tex]C(q) = 50+16q\\\\C(500)=50+16(500)=50+8,000=8,050[/tex]

b) The price for each sheet is $20, so the income from sales are:

[tex]S(q)=20q\\\\S(500)=20\cdot 500 = 10,000[/tex]

c) Table of values

[tex]\left[\begin{array}{ccc}q&C(q)&S(q)\\0&50&0\\250&4,050&5,000\\500&8,050&10,000\end{array}\right][/tex]

d) Attached

e) The minimum number of sheets the group must sell so they don't lose any money is the breakeven point (BEP) and can be calculated making the income sales equal to the cost:

[tex]S(q)=C(q)\\\\20q=50+16q\\\\(20-16)q=50\\\\4q=50\\\\q=50/4=12.5[/tex]

f) This profit can be calculated as the difference between the sales income and the cost:

[tex]P(500)=S(500)-C(500)\\\\P(500)=20\cdot 500-(50+16\cdot 500)=10,000-8,050=1,950[/tex]

The given number of 500 sheets of stamps purchased at $16/sheet with

a plan to sell each sheet for $20 gives the following values;

(a) Cost, C = 50 + 16·q

(b) Income, R = 20·q

(c) Please find the included table of values and the attached graph

(e) Approximately 403 sheets

(f) $1,950

(a) The cost per sheet of stamp = $16/sheet

The cost to create the image = $50

Amount at which they plan to sell each sheet, P = $20

Therefore

(b) The income from sale, R = Number of units sold × P

Which gives;

(c) The table of values are therefore;

C = 50 + 16·q

[tex]\begin{array}{|c|c|c|}q&C=50+16 \times q\\0&50\\1&66\\2&82\\3&98\\4&114\\5&130\\6&146\\7&162\\8&178\\9&194\\10&210\\11&226\\12&242\\13&258\\14&274\end{array}\right][/tex]

R = 20·q

[tex]\begin{array}{|c|c|c|}q&R = 20 \times q\\0&0\\1&20\\2&40\\3&60\\4&80\\5&100\\6&120\\7&140\\8&160\\9&180\\10&200\\11&220\\12&240\\13&260\\14&280\end{array}\right][/tex]

Please find attached the required graph created with MS Excel

e) The minimum number of sheets the group must sell is given as follows;

The cost of the sheets purchased = 50 + 16 × 500

Which gives;

At point of profitability; Income = Cost

50 + 16 × 500 = 20·[tex]q_{min}[/tex]

[tex]q_{min} = \dfrac{50 + 16 \times 500}{20} =402.5 \approx \mathbf{403}[/tex]

(f) The profit made by selling 500 sheets is; 20·q - (50 + 16·q)

Where;

q = 500

Which gives;

20 × 500 - (50 + 16 × 500) = 1,950

The profit made from selling 500 sheet = $1,950

The other solution is 0.56

Step-by-step explanation:

The quadratic equation is;

4x^2 + 45x + 24

a is the coefficient of x^2 which is 4

b is the coefficient of x which is 45

c is the third number which is 24

Using the quadratic formula, we have

x = {-b ± √(b^2-4ac)}/2a

So inputing the values we have highlighted above, we have

x = {-45 ± √(45^2-4(4)(24)}/2(4)

x = {-45 ± √(2025-4(4)(24)}/2(4)

x = {-45 ± √1641}/2(4)

x = {-45 ± 40.51}/2(4)

x = (-45+40.51)/8 or (-45-40.51)/8

x = 0.56 or -10.69
