Kevin has $500 in his savings account and he deposits $25 each week. Janet has $250 in her savings account and she deposits $50 each week.


(a) Write a system of equations that represents the scenario

(b) Solve the system to determine after how many weeks Kevin and Janet will have the same amount of savings. What will that amount be?

Answers

Answer 1

Answer:

(a) Let x be the number of weeks and let y be the total amount in their savings accounts. Then, the system of equations that represents the scenario is:

Kevin: y = 25x + 500

Janet: y = 50x + 250

(b) To determine after how many weeks Kevin and Janet will have the same amount of savings, we need to solve the system of equations by setting them equal to each other:

25x + 500 = 50x + 250

Subtracting 25x and 250 from both sides, we get:

250 = 25x

Dividing both sides by 25, we get:

x = 10

Therefore, Kevin and Janet will have the same amount of savings after 10 weeks. To find out what that amount is, we can substitute x = 10 into either equation:

y = 25x + 500

y = 25(10) + 500

y = 750

So after 10 weeks, both Kevin and Janet will have $750 in their savings accounts.

The radius of the circular base of a cone measures 1.6 inches, and its slant height measures 2.5 inches.

What is the approximate lateral area of the cone?

Use π≈3.14.

Enter your answer rounded to the nearest tenth in the box.

Answers

Answer:

ans=8.80inch

Step-by-step explanation:

given,

radius(r)=1.6 inch

height(h=2.5 inch

laternal area of cone = AL=√πrh2+r2

√3.14*2.5^2+1.6^2

8.80 inch

The approximate lateral area of the cone is,

⇒ LSA = 10.5 inches

What is Multiplication?

To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.

To find the approximate lateral area of the cone, we need to know the height of the cone.

Since we are not given the height, we can use the Pythagorean theorem to find it:

Slant height² = h² + r²

2.5² = h² + 1.6²

6.25 = h² + 2.56

h² = 6.25 - 2.56

h² = 3.69

h = √3.69

h = 1.92 in

We know that;

The lateral surface area of a cone is calculated using the formula,

LSA =πr√(r² + h²) square units.

Substitute all the values, we get;

LSA =πr√(r² + h²) square units.

LSA = 3.14 × 1.4√(1.6² + 1.9²) square units.

LSA = 5 √2.6 + 3.6

LSA = 5 √4.2

LSA = 5 × 2.1

LSA = 10.5 inches

Thus, The approximate lateral area of the cone is,

⇒ LSA = 10.5 inches

which graph shows the solution to x-2y>9

Answers

The correct graph that shows the solution to x - 2y > 9 is B.

What is graph?

In mathematics, graphs can represent functions or equations, such as a line on a coordinate plane or a curve in a three-dimensional space. Graphs can also be used to represent data, such as a bar graph or a scatterplot, which can help to identify trends or correlations between different variables.

To graph the solution to the inequality x - 2y > 9, we can start by graphing the boundary line x - 2y = 9, which is the equation that results from replacing the inequality symbol with an equal sign.

The boundary line can be graphed by plotting two points on the line and connecting them with a straight line. To do this, we can choose any two values for x and y that satisfy the equation x - 2y = 9, such as:

x = 0, y = -4.5, giving us the point (0, -4.5)x = 9, y = 0, giving us the point (9, 0)

We need to determine which side of the boundary line represents the solution to the inequality x - 2y > 9. To do this, we can choose a test point on one side of the boundary line, such as (0, 0), and substitute its coordinates into the inequality.

Substituting (0, 0) into the inequality x - 2y > 9 gives:

0 - 2(0) > 9

which simplifies to:

0 > 9

The side of the line containing (0, 0) is not the solution. Therefore, the solution to the inequality x - 2y > 9 is the side of the line that does not contain the point (0, 0).

Therefore, the correct graph that shows the solution to x - 2y > 9 is B.

Owen invests money in an account paying a simple interest of 5.6% per year. If he invests $110 and no money will be added or removed from the investment, how much will he have in one year, in dollars and cents?

Answers

Owen will have $116.60 in one year. The same principal amount is used for the calculation every period, and the interest earned each period will be the same.

What is principal amount?

Principal amount is the total amount of money borrowed or invested, excluding any interest, fees or other charges.

This can be calculated using the formula for simple interest, where

I = P x R x T, where P is the principal (the initial investment), R is the interest rate expressed as a decimal, and T is the time.

In this case, the principal (P)= $110,

the interest rate (R) = 0.056,

and the time (T)= 1 year.

Therefore, I = 110 x 0.056 x 1

= 6.16.

When this is added to the original principal of $110, we get $116.16.

This is happening because simple interest is calculated on the principal amount only.

It is not compounded, so the interest is not added to the principal and then used to calculate the interest in the next period.

Therefore, the same principal amount is used for the calculation every period, and the interest earned each period will be the same.

a) The maximum error in the calculated area of the disk =  23.87 cm²

b) The relative error is: 0.0211 and the percentage error is 2.11%

Let us assume that r represents the radius of the circular disk and A represents the area.

Here, the radius of a circular disk is given as 19 cm

So, r = 19 cm

and the radius has a maximum error in measurement of 0.2 cm.

So, dr = 0.2

The area of the circular disk would be,

A = πr²            ..........(1)

A = π × 19²

A = 361π cm²

Differentiating equation (1) with respect to r,

dA = 2πr × dr

dA = 2 × π × 19 × 0.2

dA = 7.6π

dA = 23.87 cm²

So, the maximum error in the calculated area is: 23.87 cm²

Now we find the relative error.

R = dA/A

R = 7.6π / 361π

R = 0.0211

In a lab experiment, the number of bacteria on a petri dish began at 7400 and is now increasing exponentially at a rate of 13% per hour. P(t) = [tex]7400(1 + 0.13)^t[/tex] is a function that may be used to represent the population of bacteria after t hours and in which a constant can be used to calculate the rate of change each minute. The rate of change in percentage is 0.21667% per minute.

The function to represent the population of bacteria after t hours can be expressed as:

P(t) = [tex]7400(1 + 0.13)^t[/tex]

where P(t) is the population of bacteria after t hours, 7400 is the initial population, and 0.13 is the growth rate per hour expressed as a decimal.

To find the rate of change per minute, we need to convert the growth rate per hour to a growth rate per minute. There are 60 minutes in an hour, so the growth rate per minute can be found by dividing the growth rate per hour by 60:

0.13/60 = 0.0021667 (rounded to seven decimal places)

So the growth rate per minute is approximately 0.0021667 or 0.21667% (rounded to two decimal places).

Therefore, the function to represent the population of bacteria after t hours is:

C. If Brown has an imputed interest charge of 22%, compute the residual income of investment no. 3. Is this investment attractive from Glengarry's perspective? From Brown's perspective? Why?

Answers

A. Investment 1: ROI = 20%, Investment 2: ROI = 18%, Investment 3: ROI = 24%. B. Select Investment 3 with the highest ROI of 24% as it generates the most return for the investment amount.

C. Investment 3 is attractive with positive residual income, but from Brown's perspective, the imputed interest charge may reduce overall profitability.

A. To calculate the ROI for each investment, we can use the following formula:

ROI = (Income / Investment) x 100%

For Investment 1: ROI = (50,000 / 250,000) x 100% = 20%

For Investment 2: ROI = (54,000 / 300,000) x 100% = 18%

For Investment 3: ROI = (96,000 / 400,000) x 100% = 24%

B. If the manager's focus is on Glengarry's divisional performance, he would select Investment 3 because it has the highest ROI of 24%. This investment generates the highest return for the amount invested, which is the primary concern for divisional performance.

C. To calculate the residual income for Investment 3, we need to subtract the imputed interest charge from its profit margin traceable to the division:

Residual Income = Profit margin traceable to the division - (Average asset investment x Imputed interest rate)

Residual Income = 96,000 - (400,000 x 22%) = 96,000 - 88,000 = 8,000

From Glengarry's perspective, Investment 3 is attractive because it generates a positive residual income of $8,000. However, from Brown's perspective, it may not be as attractive because the imputed interest charge reduces the overall profitability of the investment.

One hose can fill a goldfish pond in 42 minutes, and two hoses can fill the same pond in 30 minutes. Find how long it takes the second hose
alone to fill the pond.
It takes __ minutes for the second hose alone to fill the pond.

Answers

It takes 105 minutes for the second hose alone to fill the pond.

What is an expression?

An expression is a combination of numbers, variables, and mathematical operations, such as addition, subtraction, multiplication, and division, among others.

Let x be the time it takes for the second hose to fill the pond alone.

The rate at which the first hose fills the pond is 1/42 (ponds/minute).

The rate at which the second hose fills the pond is 1/x (ponds/minute).

The combined rate at which the two hoses fill the pond is 1/30 (ponds/minute).

Since they are filling the same pond, we can add their rates to get the combined rate:

⇒ 1/42 + 1/x = 1/30

To solve for x, we can simplify this equation;

⇒ 30x + 1260 = 42x

Subtracting 30x from both sides gives:

⇒ 1260 = 12x

⇒ x = 105

Therefore, it takes the second hose alone 105 minutes to fill the pond.

To find the probability that the mean time spent reading each day is between 24.7 and 25.5 minutes, we need to standardize the sample mean using the Central Limit Theorem and the z-score formula:

z = (x - μ) / (σ / √(n))

where μ is the population mean (unknown), σ is the population standard deviation (known), and √(n) is the square root of the sample size.

We can approximate the population mean with the sample mean since the sample size is large (n ≥ 30) and assume a normal distribution for the sample mean.

First, we standardize the lower bound of the range:

z1 = (24.7 - 25) / (1.5 / √(50)) = -1.76

Then, we standardize the upper bound of the range:

z2 = (25.5 - 25) / (1.5 / √(50)) = 1.76

Using a standard normal distribution table or calculator, we can find the area under the curve between z1 and z2:

P(-1.76 ≤ z ≤ 1.76) ≈ 0.919

Therefore, the probability that the mean time people spend reading books each day is between 24.7 and 25.5 minutes is approximately 0.919 or 91.9%.

The value of x in the given triangle is 36.87°.

What is Trigonometric function?

One of the six functions in mathematics is the trigonometric function (sine [sin], cosine [cos], tangent [tan], cotangent [cot], secant [sec], and cosecant [csc]) In trigοnοmetry, sin cοs and tan values are the primary functiοns we cοnsider while sοlving trigοnοmetric prοblems. These trigοnοmetry values are used tο measure the angles and sides οf a right-angle triangle. Apart frοm sine, cοsine and tangent values, the οther three majοr values are cοtangent, secant and cοsecant.

According to Trigonometric function,

Tan θ = Opposite side/Adjacent side

Therefore,

Tan θ = 6/8

θ = arctan(6/8)

θ ≈ 36.87°

This is simplest way to calculate, there is no other way to calculate.

Thus, the value of x in the given triangle is 36.87°.

sofia has a rectangular poster that is 42 inches long and 30 inches high

Answers

Sofia has a rectangle poster that is 42 inches long and 30 inches wide.  The area of the poster is 1260 square inches.

The area of ​​a rectangle depends on its sides. Basically, the area formula is equal to the product of the length and width of a rectangle. When we talk about the perimeter of a rectangle, it is equal to the sum of its four sides. Therefore, we can say that the area bounded by the perimeter of a rectangle is its area. But in the case of a square, since all sides are equal, the area of ​​the square will be equal to the square of its length.

area of ​​rectangle = length x width

We know that :

Area of rectangle = Length × Breadth

                             = 42 × 30 inches

                             = 1260 square inches.

Therefore, the area of a rectangle is 1260 square inches.

to avoid an unbalanced lineup, the coach wants to choose 2 of her guards and 3 of her forwards/ centers. to do this, she places the names of her 5 guards in one hat and the names of her 7 forwards/centers in a second hat. then, she will randomly select 2 guards from the first hat and 3 forwards/ centers from the second hat.how many different lineups are possible?

Answers

There are 350 different lineups that can be created.

The question here is regarding the possibility of different lineups given that there are two groups of players available - guards and forwards/centers. The coach wants to choose 2 of her guards and 3 of her forwards/ centers. To avoid an unbalanced lineup, she places the names of her 5 guards in one hat and the names of her 7 forwards/centers in a second hat. Then, she will randomly select 2 guards from the first hat and 3 forwards/ centers from the second hat.

How many different lineups are possible?

In order to get the different possibilities of lineups, we need to calculate the total number of ways we can select the guards and the forwards/centers separately.

Total number of ways to select guards =[tex]5C_2 = (5 \times 4) / (2 \times 1) = 10[/tex]

Total number of ways to select forwards/centers = [tex]7C_3 = (7 \times 6 \times 5) / (3 \times 2 \times 1) = 35[/tex]

Thus, the total number of ways the lineup can be created is 10 × 35 = 350.

determine the value of such that the matrix is the augmented matrix of a linear system with infinitely many solutions.

Answers

The value of such that the matrix is the augmented matrix of a linear system with The system has an infinite number of solutions if $k=-1$.

To find out the value of $k$ that results in the matrix being the augmented matrix of a linear system with infinitely many solutions, you need to reduce the matrix to row echelon form and check the conditions. If you get a row of all zeroes but the last entry in that row is not zero, then there is no solution. If you get a row of all zeroes including the last entry in that row, then there are infinitely many solutions. Therefore, the value of $k$ that leads to the augmented matrix of a linear system with infinitely many solutions is $k=-1$.

A system of linear equations has an infinite number of solutions if and only if its augmented matrix, after being transformed to row-echelon form, has at least one free variable column.

The matrix in question is given as:

[tex]$$\begin{bmatrix}2 & -2 & 4 \\ -3 & 3 & -6 \\ 1 & -1 & k\end{bmatrix}$$[/tex]

To find the value of $k$, we need to convert it to a row-echelon form.

[tex]$$ \begin{bmatrix}2 & -2 & 4 \\ -3 & 3 & -6 \\ 1 & -1 & k\end{bmatrix} \overset{R2\rightarrow R2+\frac{3}{2}R1}{\longrightarrow} \begin{bmatrix}2 & -2 & 4 \\ 0 & 0 & 0 \\ 1 & -1 & k\end{bmatrix} $$[/tex]

Notice that the second row of the matrix is all zeros, so the system either has no solution or has an infinite number of solutions. Therefore, we need to determine the value of $k$ to figure out which of the two cases apply. Since the third row is independent, we can choose to work with it only.

[tex]$$1a - 1b = c \rightarrow c = a - b$$[/tex]

We can also write it as a linear combination of $a$ and $b$:

[tex]$$\begin{aligned} c &= a - b \\ &= a(1) + b(-1) \end{aligned}$$[/tex]

Therefore, it follows that if $k$ equals -1, we can rewrite the last row as a linear combination of the first two rows.
