In this problem, we want to write a model/equation that will represent the cost of producing a phone

Given, labor and materials cost per phone is $100

the cost of producing 8 phones a day is $1300

let us find the cost of producing one phone a day

8 phone is produced for $1300

1 phone will be for x

x= 1300/8

x=$162.5

The cost of producing a phone in a  day is $162.5

therefore the of producing p phone in a day is 162.5p

if C represents the total cost of producing a phone

then total cost, in dollars, of producing p phones in a given day.

C=100+162.5p

Answer: C = 100p + 500

4 2/4÷2= 2 1/4

Answer:

2 1/4

Step-by-step explanation:

Set up a table with the labels flour and cookies on the flour side have 4 1/2 on the cookies side have 48 then in another row 24. Divide 24 by 48 to find out what to multiply 4 1/2 by to get the answer.48 divided by 24 is .5 so you would multiply 4 1/2 by .5 to get 2 1/4

it means the line will be solid, not dashed. Also, because the y variable is on the less than side of the equation, it means the shaded are will be under the line.

Answer:

Step-by-step explanation:

Ist method - Area of the triangle + Area of the  trapezium

Area of triangle = 1/2 × b × h

here, b = 8 cm but h is not given

so we will find h by pythagoras theorem

AC^2 = AB^2 + BC^2

10^2 = 8^2 + BC^2

100 = 64 + BC^2

BC^2 = 36

BC = √36

BC = 6

∴ h = 6cm

area of triangle = 1/2 × b × h

= 1/2 × 8 × 6

= 24 cm^2

Area of trapezium = 1/2 ( a + b ) h

Here a = 13cm

         b = 25 - 8 = 17 cm

         h = 6 cm

So area = 1/2 ( a + b ) h

= 1/2 ( 13 + 17 ) 6

= 90 cm^2

So total area =  Area of the triangle + Area of the  trapezium

= 24 cm^2 + 90 cm^2 = 114 cm^2

2nd method - Area of the entire figure

Since the figure is a trapezium,

Area of trapezium = 1/2 ( a + b ) h

here, a = 13cm

        b = 25 cm

        h = 6 cm

Area of trapezium = 1/2 ( a + b ) h

= 1/2 ( 13 + 25 ) 6

= 114 cm^2

Answer:

x = -19

Step-by-step explanation:

hope this help :)

Answer:

[tex]\boxed {x = -19}[/tex]

Step-by-step explanation:

Solve for the value of [tex]x[/tex]:

[tex]-4(x + 1) - 3 = -3(x - 4)[/tex]

-Use Distributive Property to both sides of the equation:

[tex]-4(x + 1) - 3 = -3(x - 4)[/tex]

[tex]-4x - 4 - 3 = -3x + 12[/tex]

-Combine like terms:

[tex]-4x - 4 - 3 = -3x + 12[/tex]

[tex]-4x - 7 = -3x + 12[/tex]

-Take [tex]-3x[/tex] and add it to [tex]-4x[/tex]:

[tex]-4x - 7 + 3x = -3x + 3x + 12[/tex]

[tex]-x - 7 = 12[/tex]

-Add both sides by [tex]7[/tex]:

[tex]-x - 7 + 7 = 12 + 7[/tex]

[tex]-x = 19[/tex]

-To make the variable [tex]x[/tex] positive, divide both sides by [tex]-1[/tex]:

[tex]\frac{-x}{-1} = \frac{19}{-1}[/tex]

[tex]\boxed {x = -19}[/tex]

Therefore, the value of [tex]x[/tex] is [tex]-19[/tex].

Answer:

She made an average of 145$ per day.

Step-by-step explanation:

If she earned 725$ in 5 days, just divide 725 by 5 for your average a day.

Step-by-step explanation:

Hi, it seems the question is not complete, therefore I'll create an example tailored to the concept of the question you are asking.

1. Cumulative property can be used to change the order of addends and the result remains the same. Therefore the law states that, if a and b are real numbers, then a + b = b + a

Think about adding two numbers, such as 7 and 2.

7 + 2 = 9

2 + 7 = 9

The results are the same.

Notice, the order in which we add does not matter.

2. Associative property, this can be used to regroup addends and the result remains the same: the law states that, if a, b and c are real numbers, then

(a + b) + c = a + (b + c).

Think about three numbers, 4, 3 and 2

(4 + 3) + 2 = 7 + 2 = 9

4 + (3 + 2) = 4 + 5 = 9

The results are the same, notice that the regrouping did not change the final result.

Thank You This Helped Alot!

Answer:

448

Step-by-step explanation:

Every 9 hours, mold doubles

Started with 14 spores

In 9 hours, 14+14= 28 spores

In 18 hours, 28+28=56 spores

In 27 hours, 56+56=112 spores

In 36 hours, 112+112=224 spores

In 45 hours, 224+224=448 spores

We want to write an equation for an exponential growth that represents the change in the population of mold.

The answer is: "After 45 hours, there would be__448__spores.​"

-----------------------------------

We know that a given type of mold doubles every 9 hours.

So if you start with a quantity A of spores, after 9 hours there are:

2*A spores.

After another 9 hours (for a total of 18 hours) the population is:

(2^2)*A spores.

You already could see the pattern.

After x hours, the number of spores will be given by:

p(x) = A*(2)^(x/9)

Now we want to know how many spores are there after 45 hours, if the initial amount is 14 spores.

So we need to replace:

Then we want to compute:

p(45) = 14*(2)^(45/9) = 448

From this, we can conclude that after 45 hours there will be 448 spores.

The equivalent ratio are 8:6, 32:24 and 4:3

A ratio is a comparison between two amounts that is calculated by dividing one amount by the other. The quotient a/b is referred to as the ratio between a and b if a and b are two values of the same kind and with the same units, such that b is not equal to 0. Ratios are represented by the colon symbol (:). As a result, the ratio a/b has no units and is represented by the notation a: b.

Given:

Ratio = 16 : 12

Simplifying the ratio

= 16/12

= 4/3

So, first 8:6

= 4: 3

and, second 32:24

= 4:3

and, third = 4:3

and, fourth 12 : 8

= 3:2

Hence, the equivalent ratio are 8:6, 32:24 and 4:3

C. The area of the blue circle is equal to the sum of areas of green square and black circle.

Step-by-step explanation:

The area of a circle is the circumference of the circle measured with its diameter. In the given scenario the area of the blue circle is greater than the area of black circle. This is because of the difference in diameter of the two circles. The area of green square plus the area of black circle equals the blue circle.

B: Distinct lines

Step-by-step explanation:

If you go to desmos graphing calculator add put the equations in you can see they never interesct

Answer:

B) distinct parallel lines

Step-by-step explanation:

First, place both equations in slope-intercept form:

y + 6 = [tex]-\frac{1}{3}[/tex] (x - 15)

y + 6 = -1/3x + 5

y = -1/3x - 1

2x + 6y = 24

6y = -2x + 24

y = -2/6x + 4

y = -1/3x + 4

Because they have the same slope and different y-intercepts, they are parallel.
