Devon is 30 years old than his son, Milan. The sum of both their ages is 56. Using the variables d and m to represent the ages of Devon and Milan, respectively, write a system of equations to describe this situation. Enter the equations below, separated by a comma.How old is Devon?

Answers

Answer 1

Let's set d as the age of Davon and m as the age of Milan.

Devon is 30 years old than his son Milan, it is represented by the equation:

[tex]d=m+30\text{ Equation (1)}[/tex]

The sum of both ages is 56, the equation that represents the situation is:

[tex]d+m=56\text{ Equation (2)}[/tex]

To find Devon's age, in equation 1, solve for m in terms of d:

[tex]m=d-30[/tex]

Now, replace in equation 2 and solve for d:

[tex]\begin{gathered} d+(d-30)=56 \\ 2d-30=56 \\ 2d=56+30 \\ 2d=86 \\ d=\frac{86}{2} \\ d=43 \end{gathered}[/tex]

Devon is 43 years old.

fine the slope of every line that is parallel to the line on the graph

Answers

Every parallel line would have the same slope because the slope formula is Δy/Δx and the difference would be the same, so the slope for the line with the given points would be -1/6, or roughly 0.167.

What is parallel lines?

Parallel lines in geometry are coplanar, straight lines that don't cross at any point. In the same three-dimensional space, parallel planes are any planes that never cross. Curves with a fixed minimum distance between them and no contact or intersection are said to be parallel.

What is slope?

A line's steepness can be determined by looking at its slope. In mathematics, slope is determined by dividing the change in y by the change in x. Determine the coordinates of two points along the line that you choose. Find the difference between these two points' y-coordinates (rise). Find the difference between these two points' x-coordinates (run). Divide the difference in x-coordinates (rise/run or slope) by the difference in y-coordinates.

Here the coordinates are (-6,0) and (0,-1)

ΔX = 0 – -6 = 6

ΔY = -1 – 0 = -1

Slope (m) =ΔY/ΔX

=-1/6

= -0.16666666666667

≈-0.167

A rectangular athletic field is twice as long as it is wide if the perimeter of the athletic field is 360 yards what are its dimensions. The width isThe length is

Answers

Step 1. We will start by making a diagram of the situation.

Since the length of the rectangle is twice the width, if we call the width x, then the length will be 2x as shown in the diagram:

Step 2. One thing that we know about the rectangle is its perimeter:

[tex]\text{Perimeter}\longrightarrow360\text{yd}[/tex]

This perimeter has to be the result of the sum of all of the sides of the rectangle:

[tex]x+x+2x+2x=360[/tex]

Step 3. Solve the previous equation for x.

In order to solve for x, the first step is to combine the like terms on the left-hand side:

[tex]6x=360[/tex]

The second step to solve for x is to divide both sides of the equation by 6:

[tex]\frac{6x}{6}=\frac{360}{6}[/tex]

Simplifying:

[tex]x=60[/tex]

Step 4. Remember from the diagram from step 1, that x was the width of the rectangle:

[tex]\text{width}\longrightarrow x\longrightarrow60yd[/tex]

and the length was 2x, so we multiply the result for the with by 2:

[tex]\text{length}\longrightarrow2x=2(60)=120\longrightarrow120yd[/tex]

And these are the values for the width and the length.

Answer:

The width is 60yd

0.4384 < p < 0.5049

Explanation:

The confidence interval for the population proportion can be calculated as:

[tex]p^{\prime}-z_{\frac{\alpha}{2}}\sqrt[]{\frac{p^{\prime}(1-p^{\prime})}{n}}

Where p' is the sample proportion, z is the z-score related to the 95% level of confidence, n is the size of the sample and p is the population proportion.

Now, we can calculate p' as the division of the number of voters of favor approval by the total number of voters.

[tex]p^{\prime}=\frac{408}{865}=0.4717[/tex]

Additionally, n = 865 and z = 1.96 for a 95% level of confidence. So, replacing the values, we get:

[tex]\begin{gathered} 0.4717-1.96\sqrt[]{\frac{0.4717(1-0.4717)_{}}{865}}

Therefore, the confidence interval for the true proportion is:

A contractor has submitted bids on three state jobs: an office building, a theater, and a parking garage. State rules do not allow a contractor to be offered more than one of these jobs. If this contractor is awarded any of these jobs, the profits earned from these contracts are: 13 million from the office building, 9 million from the theater, and 4 million from the parking garage. His profit is zero if he gets no contract. The contractor estimates that the probabilities of getting the office building contract, the theater contract, the parking garage contract, or nothing are .17, .27, .45, and .11, respectively. Let x be the random variable that represents the contractor's profits in millions of dollars. Write the probability distribution of x. Find the mean and standard deviation of x.

Answers

Answer:

Probability distribution:

13 0.17

9 0.27

4 0.45

0 0.11

Mean: 6.44

Standard deviation: 4.04

Explanation:

The probability distribution is a table that shows the profits earned and its respective probabilities, so:

x (million) P(x)

13 0.17

9 0.27

4 0.45

0 0.11

Then, the mean can be calculated as the sum of each profit multiplied by its respective probability. Therefore, the mean E(x) is equal to:

E(x) = 13(0.17) + 9(0.27) + 4(0.45) + 0(0.11)

E(x) = 2.21 + 2.43 + 1.8 + 0

E(x) = 6.44

Finally, to calculate the standard deviation, we first need to find the differences between each value and the mean, and then find the square of these values, so:

x x - E(x) (x - E(x))²

13 13 - 6.44 = 6.56 (6.56)² = 43.03

9 9 - 6.44 = 2.56 (2.56)² = 6.55

4 4 - 6.44 = -2.44 (-2.44)² = 5.95

0 0 - 6.44 = -6.44 (-6.44)² = 41.47

Then, the standard deviation will be the square root of the sum of the values in the last column multiply by each probability:

[tex]\begin{gathered} s=\sqrt[]{43.03(0.17)+6.55(0.27)+5.95(0.45)+41.47(0.11)} \\ s=\sqrt[]{16.3264} \\ s=4.04 \end{gathered}[/tex]

Therefore, the answers are:

Probability distribution:

x (million) P(x)

In the graph you can see that the line passes through 2 points (-4,0) and (0,2). With them you can obtain the equation of the line. First you find the slope of the line with the following equation

[tex]\begin{gathered} m=\frac{y_2-y_1}{x_2-x_1} \\ \text{Where} \\ m\colon\text{ Slope of the line} \\ (x_1,y_1)\colon\text{ Coordinates of first point }on\text{ the line} \\ (x_2,y_2)\colon\text{ Coordinates of second point }on\text{ the line} \end{gathered}[/tex]

So you have,

[tex]\begin{gathered} (x_1,y_1)=(-4,0) \\ (x_2,y_2)=(0,2) \\ m=\frac{y_2-y_1}{x_2-x_1} \\ m=\frac{2-0}{0-(-4)} \\ m=\frac{2}{4}=\frac{1}{2} \end{gathered}[/tex]

Now, with the point slope equation you can obtain the equation of the line

[tex]\begin{gathered} y-y_1=m(x_{}-x_1) \\ y-0=\frac{1}{2}(x-(-4)) \\ y=\frac{1}{2}(x+4) \\ y=\frac{1}{2}x+\frac{1}{2}\cdot4 \\ y=\frac{1}{2}x+\frac{4}{2} \\ y=\frac{1}{2}x+2 \end{gathered}[/tex]

The required point-slope form of the equation of the line exists y + 9 = 4/3 (x + 9).

What is the slope of the line?

A slope of a line exists the change in the y coordinate with respect to the change in the x coordinate. The net change in the y-coordinate exists defined by Δy and the net change in the x-coordinate exists defined by Δx. Where “m” exists the slope of a line. So, tan θ to be the slope of a line.

The slope of the line exists a tangent angle created by line with horizontal.

i.e. m = 4/3 where x in degrees.

The point-slope of the equation of the line is given by,

y - y₁ = m(x - x₁)

[tex]C=3.60(4x^2+10xh)[/tex]

By substituting the height result from above, we have

[tex]C=3.60(4x^2+10x(\frac{12}{x^2}))[/tex]

which gives

[tex]C=3.60(4x^2+\frac{120}{x})[/tex]

Now, in order to find minum cost, we need to find the first derivative of the function cost and equate it to zero. It yields,

[tex]\frac{dC}{dx}=3.60(8x-\frac{120}{x^2})=0[/tex]

which is equivalent to

[tex]\begin{gathered} 8x-\frac{120}{x^2}=0 \\ \text{then} \\ 8x=\frac{120}{x^2} \end{gathered}[/tex]

by moving x squared to the left hand side and the number 8 to the right hand side, we have

[tex]\begin{gathered} x^3=\frac{120}{8} \\ x^3=15 \\ \text{then} \\ x=\sqrt[3]{15} \\ x=2.4662 \end{gathered}[/tex]

Therefore, by substituting this value in the height function, we get

[tex]h=\frac{12}{2.4662^2}=1.9729[/tex]

therefore, by rounding to the neastest hundredth, the height which minimize the cost is equal to 1.97 cm

Pep Boys Automotive paid $208.50 for a pickup truck bed liner. The original selling price was $291.90, but this was marked down 35%. If operating expenses are 28% of the cost, find the absolute loss

Answers

Step 1: State the given in the question

THe following were given:

[tex]\begin{gathered} \text{Amount Paid (}A_{\text{paid}})=208.50 \\ (Originalsellingprice)SP_{ORIGINAL}=291.90 \\ \text{Marked Percentage=35\%} \\ \text{Operating expenses=28\%} \end{gathered}[/tex]

Step 2: State what is to be found

We are to find the absolute loss

Step 3: Calculate the selling price

Please note that the selling price is the marked down price

The marked down price would be

[tex]\begin{gathered} P_{\text{MARKED DOWN}}=(100-35)\text{ \% of original selling price} \\ P_{\text{MARKED DOWN}}=65\text{ \% of }SP_{ORIGINAL} \\ P_{\text{MARKED DOWN}}=\frac{65}{100}\times291.90=189.74 \end{gathered}[/tex]

The selling price is the marked down price which is $189.74

Step 4: Calcualte the operating expenses

Please note that the cost price is amount paid. Therefore, the operating expenses would be as calculated below:

[tex]\begin{gathered} E_{\text{OPEARATING}}=28\text{ \% of Amount Paid} \\ E_{\text{OPERATING}}=28\text{ \% of }A_{\text{paid}}=\frac{28}{100}\times208.50 \\ E_{\text{OPERATING}}=0.28\times208.50=58.38 \end{gathered}[/tex]

Hence, the operating expenses is $58.38

Step 5: Calculate the total cost price

The total cost price is the addition of the cost price and the operating expenses. This is as calculated below:

[tex]\begin{gathered} C_{\text{TOTAL COST PRICE}}=E_{OPERATING}+A_{PAID} \\ C_{\text{TOTAL COST PRICE}}=58.38+208.50=266.88 \end{gathered}[/tex]

Hence, the total cost price is $266.88

Step 6: Calculate the absolute loss

The absolute loss is the difference between the total cost price and the marked down price (or the actual selling price). This is as calculated below:

[tex]\begin{gathered} L_{\text{ABSOLUTE LOSS}}=C_{TOTAL\text{ COST PRICE}}-P_{MARKED\text{ DOWN}} \\ L_{\text{ABSOLUTE LOSS}}=266.88-189.74=77.14 \end{gathered}[/tex]

Hence, the absolute loss is $77.14

45% of 240 is what number?

Answers

We are asked to determine the 45% of 240. To do that we need to multiply 240 by 45/100, that is:

[tex]240\times\frac{45}{100}=108[/tex]

therefore, 45 percent of 240 is 108

In the given figure, find the mesure of angle BCD

Answers

Since the sum of angles in a triangle is 180°, it follows that;

[tex]\begin{gathered} 4x+3x+2x=180 \\ 9x=180 \\ \text{ Divide both sides of the equation by }9 \\ \frac{9x}{9}=\frac{180}{9} \\ x=20 \end{gathered}[/tex]

Since line segment AB is parallel to the line segment CD, it follows from the Corresponding angles theorem that:

[tex]\begin{gathered} \angle{B}=\angle{BCD} \\ \text{ Therefore:} \\ \angle{BCD}=4x \\ \text{ Substitute }x=20\text{ into the equation} \\ \angle{BCD}=4\times20=80 \end{gathered}[/tex]

The value of the expression x² + 5x + 4 is found as 4.

What is termed as the quadratic expression?A quadratic expression is one that has the variable with highest power of two. A quadratic expression is one that has the form ax² + bx + c, in which a ≠ 0.Typically, the expression is written in the form of x, y, z, or w.In such a quadratic expression brought up to the power of 2, the variable 'a' cannot be zero. If a = 0, x² is multiplied by zero, and the expression is no longer a quadratic expression.Variables b and c with in standard form can indeed be zero, but variable a cannot.

for the given question,

The quadratic expression is given as;

= x² + 5x + 4

Put x = -5

= (-5)² + 5(-5) + 4

Simplifying.

= 25 - 25 + 4

25 will get cancelled.

= 4

Thus, the value of the expression is found as 4.
