Step-by-step explanation:

Given,

The length of a rectangle(l) = 2(x + 1) meters and  

The perimeter of a rectangle = 60 meters

To find, the width of a rectangle(b) = ?

We know that,

The perimeter of a rectangle = 2(l + b)

⇒  2(2(x + 1) + b) = 60

⇒  2(x + 1) + b =[tex]\dfrac{60}{2} =30[/tex]

⇒ b = 30 - 2(x + 1)

⇒ b = 30 - 2x - 2

⇒ b = 28 - 2x

⇒ b = 2(14 - x)

∴ The width of a rectangle(b) = 2(14 - x)

Hence, the width of a rectangle(b) = 2(14 - x)

Answer:

The value of y in the given equation is B. 30.

Step-by-step explanation:

y = 2x² - 4x             x = 5

y = 2(5)² - 4(5)        Plug 5 in for x

y = 2(25) - 20         Square 5 and multiply 4 by 5

y = 50 - 20             Multiply 2 by 25

y = 30

Answer:

3 ounces of medication to be added to get 20%solution of medication

Step-by-step explanation:

To find:

The amount of medication to be added to 12 ounces of water to get a 20% solution

Let the amount of medication to be added =x

So total amount of mixture = amount of water + amount of medication

= 12+x

% medication =  (amount of medication÷total amount of the mixture)× 100

Therefore

% medication =(  x÷12+x)×100

20 =(  x÷12+x)×100

[tex]20 =\frac{x}{12+x}[/tex] X 100

20(12+x) =100x

240+20x =100x

100x-20x =240

80x =240

x =240÷80

x=3

so 3 ounces of medication to be added to get 20%solution of medication

Answer:

Step-by-step explanation:

∠ABC = ∠BCD    { AB // CD; BC TRAVERSAL, alternate angles are equal}

∠ABC = 20

∠BCA = ∠BAC     {angles opposite to equal sides are equal}

∠BCA = ∠BAC = x

x + x + 20 = 180

2x = 180 - 20

2x = 160

x = 160/2

x = 80

The lines AB and CD are said to be parallel and thus, corresponding angles ∠CB and ∠BD, are equal in value. Hence the value of x is calculated by subtracting the value of known angle ∠BCD (20°) from the total sum of interior angles of a straight line (180°), obtaining a result of 160°.

In this given geometry problem, the lines AB and CD are parallel to each other and BC∠BCD = 20°. Since AB is parallel to CD, then the angles ∠CB and ∠BD, being corresponding angles, are equal. Hence, ∠CB also equals 20°.

Now, since ∠BCD and ∠CB make a straight line, the sum of their interior angles is equal to 180°. So, if we subtract the known 20° from 180°, we can find the value of unknown angle ∠BCD. Hence, x = 180° - 20° = 160°.

Answer: 200.96 yd²

Step-by-step explanation: To find the area of a circle, start with the formula for the area of a circle.

[tex]Area = \pi r^{2}[/tex]

Notice that here, we're given the diameter instead of the radius. Remember that the radius is equal to half of the diameter so the radius of this circle will be equal to half of 16 yards or 8 yards.

So plugging into the formula, we have (π)(8 yd)².

A common mistake is to plug 16 yards into the formula but remember that we must plug in the radius and not the diameter.

Multiplying, (8 yd)² is equal to 8 yards × 8 yards or 64 yards².

So we have 64π yd².

So the area of the circle is 64π yd².

Now, remember that the irrational number π is approximately equal to 22/7 or 3.14 so we can estimate the area of the circle by plugging in 3.14 for π.

So we have (64)(3.14) which is equal to 200.96.

So the area of the circle is approximately equal to 200.96 yd².

Final answer:

The area of a circle with a diameter of 16 yards is 200.96 square yards, calculated using the formula A = πr², with π approximated as 3.14.

Explanation:

To calculate the area of a circle with a diameter of 16 yards, we first determine its radius, which is half the diameter. The radius (r) would therefore be 8 yards. We use the formula for the area of a circle, which is A = πr². Since we're using 3.14 for π, we plug in the radius to get the area:

A = 3.14 × (8 yd)²

A = 3.14 × 64 yd²

A = 200.96 yd²

Therefore, the area of the circle is 200.96 square yards.

The computer cost is $3000

Step-by-step explanation:

The given is:

We need to find the cost of the computer

Assume that the price of the computer is $x

∵ The ratio between the prices of the tv and the computer is 13 : 15

∵ The price of the computer is $x

∵ The price of the tv 400 dollars cheaper than the computer

- That means the price of the tv is less than the price of the

  computer by $400

∴ The price of the tv is $(x - 400)

By using the ratio method

→  tv              :    computer

→  13              :    15

→  (x - 400)   :    x

By using the cross multiplication

∴ 15(x - 400) = 13(x)

- Simplify the left hand side

∴ 15x - 6000 = 13x

- Add 6000 to both sides

∴ 15x = 13x + 6000

- Subtract 13x from both sides

∴ 2x = 6000

- Divide both sides by 2

∴ x = 3000

The computer cost is $3000

Answer:

The manual cost that will take to recreate by the firm is $ 90.51

Step-by-step explanation:

Given:

Number of words the manual contains= 16000

Number of words typed by a clerk in one hour and 20 minutes = 4160

To Find:

The total cost for recreating the manual = ?

Solution:

Step 1:  Finding the Number of hours is need to type 4160 words :

= [tex]1\frac{20}{60}[/tex] hours

[tex]\\\\=1\frac{1}{3}[/tex] hours

[tex]\\\\=\frac{4}{3}[/tex] hours

So it takes  [tex]\frac{4}{3}[/tex] hours to type 4160 word

Step 2 :  Finding the Number of hours is needed to type 1 word  

= [tex]\frac{4160}{\frac{4}{3}}[/tex]

=[tex]4160 \times \frac{3}{4}[/tex]

= 3120 words per hour

Step 3 :  Finding the Number of hours is needed to type 16000 words

=[tex]\frac{\text{ total number of words}} {\text{ number of words written per hour}}[/tex]

Substituting the values

= [tex]\frac{16000}{3120}[/tex]

=  5.1282 hours

Step 4 :  Finding the cost for recreating the manual.

= number of hours  x cost per hour

=   5.1282 x $17.65

=  90.51

Recreating the manual will cost the firm approximately $90.59.

To determine the cost of recreating the manual, we need to calculate both the time it will take for the clerk to type the entire manual and the total cost based on the clerk's wage.

First, we calculate the time required to type the manual. The clerk types 4,160 words in 1 hour and 20 minutes. To find out how many minutes that is, we convert 1 hour to minutes:

1 hour = 60 minutes

Therefore, 1 hour and 20 minutes is:

60 minutes + 20 minutes = 80 minutes

Now, we need to find out how many 80-minute blocks are required to type 16,000 words. We set up a proportion:

4,160 words / 80 minutes = 16,000 words / x minutes

Solving for x gives us:

x = (16,000 words x 80 minutes) / 4,160 words

x = (16 x 80) / 4.16

x = 1,280 / 4.16

x ≈ 308 minutes

Next, we convert the total time from minutes to hours since the clerk is paid by the hour:

308 minutes / 60 minutes per hour ≈ 5.13 hours

Now, we calculate the total cost by multiplying the total hours by the clerk's hourly wage, including benefits:

Total cost = 5.13 hours x $17.65/hour

Total cost ≈ $90.59

Therefore, recreating the manual will cost the firm approximately $90.59.

Answer:

Slope is -0.75

Step-by-step explanation:

When calculating slope you can use the formula [tex]\frac{y_{2}-y_{1}}{x_{2}-x_{1} }[/tex] to find the slope. In this case that formula is using the 2 points (-5, -0.75) and (-6, 0). When those points are put in the equation becomes [tex]\frac{0+0.75}{-6+5}=\frac{0.75}{-1}=-0.75[/tex]. This means that the slope is -0.75.

Answer:

c ≤ - 32

Step-by-step explanation:

It will be less than or equal to - 26 if a number c is increased by 6.

Now, we have to solve the inequality for c.

The inequality is, c + 6 ≤ - 26

⇒ c + 6 - 6 ≤ - 26 - 6 {Subtracting 6 from both the sides}

⇒ c ≤ - 32

Therefore, the solution of the inequality is that c is less than or equal to - 32. (Answer)

To find the total cost for Don's class trip, including the bus rental and theater tickets, the cost and number of tickets are required. Currently, with only the bus rental cost known at $168, we can't calculate the final total cost.

To solve the problem of determining the total cost of the bus rental and theater tickets for Don's class, we first identify the information given and what is required. We know the cost of the bus rental, which is $168. However, the question does not specify the cost of theater tickets. Therefore, to get the total cost, we would need the number of theater tickets needed and the price per ticket. Once these details are provided, the total cost can be calculated using the formula:

Total Cost = Cost of Bus Rental + (Number of Theater Tickets × Cost per Theater Ticket)

Without the cost and quantity of theater tickets, we can only provide the initial part of the answer, which is the cost of the bus rental.

Answer:

27 flowers

Step-by-step explanation:

Let

x ----> the number of roses

y ----> the number of carnations

z ----> the number of daisies

we know that

[tex]x=3y[/tex] ----> equation A

[tex]y=z-12[/tex] -----> equation B

[tex]z=15[/tex] -----> equation C

substitute the value of z in equation B

[tex]y=15-12=3[/tex]

substitute the value of y in equation A

[tex]x=3(3)=9[/tex]

so

Rachel have 9 roses, 3 carnations and 15 daisies

In total

9+3+15=27 flowers

Rachel has 15 daisies, 3 carnations, and 9 roses, giving her a total of 27 flowers.

Let's break down the information provided:

Step-by-Step Solution:

1. Start with the number of daisies: 15 daisies.

2. Rachel has 12 fewer carnations than daisies:
    15 daisies - 12 = 3 carnations.

3. Rachel has 3 times as many roses as carnations:
    3 carnations * 3 = 9 roses.

4. Add up all the flowers she has:
    15 daisies + 3 carnations + 9 roses = 27 flowers in total.

Therefore, Rachel has a total of 27 flowers.

a)Exercise hour per day is 0.903

b) Exercise hour per day is 0.01573

c) The predicted values are closer to given data points.

What line of best fit?

The line of best fit is a straight line that minimizes the sum of squared differences between observed and predicted values.

From the graph we can find the line equation.

Social media hours per day/1.4 + Exercise hour per day/1.1 = 1

a) If 0.25 hours were spent on social media per day.

0.25/1.4 + Exercise hour per day/1.1 = 1

Exercise hour per day = (1 - (0.25/1.4))*1.1

Exercise hour per day = 0.8215*1.1

= 0.903

b) Social media hours per day/1.4 + Exercise hour per day/1.1 = 1

Given that 1.38 hours were spent on social media

1.38/1.4 + Exercise hour per day/1.1 = 1

Exercise hour per day/1.1 = 1 -(1.38/1.4))

Exercise hour per day = 0.0143*1.1

= 0.01573

c) The predictions from a) and b) are correct because the line almost fits the data points. The line on the data point is minimum error. The line gives the estimated values not the actual values. The predicted values are closer to given data points.
