Answer:

6.25 minutes

Step-by-step explanation:

First, let's simplify it down. We want to find out how many shirts she can fold in 1 minute, then multiply that by 50.

20 shirts in 2.5 minutes

20 shirts = 2.5 minutes

An equals sign is like a see-saw. If you do something to one side, you have to do it to the other side. To get 20 shirts to 1 one shirt, divide by 20. You have to do that to the other side to make it equal.

(20 divided by 20) = (2.5 divided by 20)

1 shirt = 0.125 minutes.

That's how long it takes to fold 1 shirt. To find the time for 50 shirts, multiply that by 50.

0.125 x 50 = 6.25

It will take Carrie 6.25 minutes to fold 50 shirts. Hope this helped =)

The number of minutes that it takes her to fold 50 shirts will be 6.25 minutes.

The rate is the ratio of the amount of something to the unit. For example - If the speed of the car is 20 km/h it means the car travels 20 km in one hour.

The definition of simplicity is making something simpler to achieve or grasp while also making it a little less difficult.

Carrie can fold 20 shirts in two and a half minutes. Then the rate is calculated as,

Rate = 20 / (2.5)

Rate = 8 shirts per minute

If she continues at this rate. Then the number of minutes that it takes her to fold 50 shirts will be given as,

⇒ 50 / 8

⇒ 6.25 minutes

The number of minutes that it takes her to fold 50 shirts will be 6.25 minutes.

x = 36

Answer: (29x-113)/24

Step-by-step explanation:

1. Separate each term from the x's

\(\frac{1}{2}\)x+\(\frac{-5}{2}\)+\(\frac{1}{8}\)x+\(\frac{-1}{8}\)+\(\frac{1}{4}\)x+\(\frac{-3}{4}\)+\(\frac{1}{3}\)x+\(\frac{-4}{3}\)

2. Group like terms together

(\(\frac{1}{2}\)x+\(\frac{1}{8}\)x+\(\frac{1}{4}\)x+\(\frac{1}{3}\)x)+(\(\frac{-5}{2}\)+\(\frac{-1}{8}\)+\(\frac{-3}{4}\)+\(\frac{-4}{3}\))

3. Find like terms of all denominators. 24 is the common denominator

2 4 6 8 10 12 14 16 18 20 22 24

8 16 24

4 8 12 16 20 24

3 6 9 12 15 18 21 24

4. Set every fraction to denominator of 24, multiply numerator by same number as the denominator

\(\frac{1}{2}\)x=\(\frac{12}{24}\)x  \(\frac{1}{8}\)x=\(\frac{3}{24}\)x  \(\frac{1}{4}\)x=\(\frac{6}{24}\)x  \(\frac{1}{3}\)x=\(\frac{8}{24}\)x   Add all new numerators together

12 +3 +6 +8=29  

\(\frac{29}{24}\)x

5. Repeat with the other set of numbers and add together

\(\frac{-5}{2}\)=\(\frac{-60}{24}\)  \(\frac{-1}{8}\)=\(\frac{-3}{24}\)   \(\frac{-3}{4}\)=\(\frac{-18}{24}\)    \(\frac{-4}{3}\)=\(\frac{-32}{24}\)      Add all new numerators together

Answer:

Use the vertical line test to determine whether or not a graph represents a function. If a vertical line is moved across the graph and, at any time, touches the graph at only one point, then the graph is a function. If the vertical line touches the graph at more than one point, then the graph is not a function.

Step-by-step explanation:

The laplace transform of the given function where a and b are real constants is \(= \frac{s}{s^2-b^2}\).

In each of problems 6 through 7 By using the linearity of the laplace transform.

To find the laplace transform of the given function:

Given f(t) = cosh(bt)

\(= \frac{e^{bt}+e^{-bt}}{2} \\\\L[e^{bt}] = \frac{1}{s-b} \\\\L[e^{bt}] = \frac{1}{s+b} \\\\\\f(s) = \frac{1}{2} [\frac{1}{s-b}+ \frac{1}{s-b} ]\\\\= \frac{1}{2}[\frac{s+b+s-b}{s^2 - b^2} ]\)

By simplifying, we get

\(= \frac{s}{s^2-b^2}\)

Hence the answer is the laplace transform of the given function where a and b are real constants is \(= \frac{s}{s^2-b^2}\).

To estimate the number of sandwiches the deli manager should anticipate selling when 178 customers visit the deli, we can analyze the given data and approximate it using a linear function.

By observing the table, we notice that the number of sandwiches sold varies with the number of customers. This indicates a relationship between the two variables.

To estimate the number of sandwiches, we can fit a line to the data points and use the linear function to make predictions. Using a statistical software or a spreadsheet, we can perform linear regression analysis to find the equation of the best-fit line. However, since we are limited to text-based interaction, I will provide a general approach.

Let's assume the number of customers is the independent variable (x) and the number of sandwiches is the dependent variable (y). Using the given data points, we can calculate the equation of the line.

After calculating the linear equation, we can substitute the value of 178 for the number of customers (x) into the equation to estimate the number of sandwiches (y).

Please provide the data points for the number of sandwiches sold corresponding to each number of customers so that I can perform the linear regression analysis and provide a more accurate estimate for you.

The number of different collections of 60 coins that can be chosen is:

(60+4-1) choose (4-1) = 63 choose 3 = 22,275

If there are at least 60 of each kind of coin, we can assume that we have four different types of coins, such as quarters, dimes, nickels, and pennies. Let's assume we have x quarters, y dimes, z nickels, and w pennies.

We know that we need to choose a total of 60 coins. Therefore, we have the following equation:

x + y + z + w = 60

We want to find the number of different collections of coins that can be chosen. This is equivalent to finding the number of non-negative integer solutions to the equation above.

Using the stars and bars formula, the number of non-negative integer solutions to this equation is:

(n+k-1) choose (k-1)

where n is the total number of objects (60 in this case) and k is the number of groups we want to divide them into (4 in this case).

So, the number of different collections of 60 coins that can be chosen is:

The speedup is 1, which means that the multi-processor system with 50 processors does not provide any speedup compared to the single-processor system.

In the single-processor system, the workload is done by a single processor. In the multi-processor system with 50 processors, one processor handles 20% of the workload, and the remaining 49 processors share the remaining 80% of the workload.

To calculate the speedup, we need to compare the time taken by the single-processor system with the time taken by the multi-processor system.

Let's assume that the time taken by the single processor to complete the workload is T_single.

In the multi-processor system, the time taken by the one processor to complete its 20% workload is 0.2 * T_single.

The remaining 80% of the workload is distributed among the other 49 processors. Each processor will handle (80% / 49) of the workload, which is approximately 1.6327% of the total workload.

Since the workload is embarrassingly parallel, each processor can work independently on its portion of the workload.

The total time taken by the multi-processor system is T_multi = 0.2 * T_single + 49 * (0.016327 * T_single) = 0.2 * T_single + 0.8 * T_single = T_single.

Therefore, the speedup of the multi-processor system compared to the single-processor system is:

Speedup = T_single / T_multi = T_single / T_single = 1

Answer: The first box (the 450 g box for $4.69)

===========================================================

Explanation:

To get the unit cost, we'll divide each price by the weight

The first box has a unit cost of (4.69)/450 = 0.010422 approximately which rounds to 0.01; so this unit cost is approximately $0.01 per gram or 1 cent per gram.

For the second box, its unit cost is (6.49)/600 = 0.0108167 approximately. When we round to the nearest cent, we get the same unit cost as before. Without rounding, we see that the first box has a slightly lower unit cost. Therefore box 1 is the better buy.

The total sum of miles ridden by Ivy this week is 75 miles.

What is meant by the sum of a quantity?

A method of combining everything is a sum. The sum creates a new total by adding up two or more numbers.

Given,

Number of miles ridden on Monday = 15 miles

Number of miles ridden on Tuesday = 10 miles

Then,

Number of miles ridden on Wednesday = 2 times the sum of 15 and 10 = 2*(15+10) = 2*25 = 50 miles

Therefore the total sum of miles ridden so far this week

                                                                    = 15 + 10 + 50 = 75 miles

Hence the total sum of miles ridden by Ivy this week is 75 miles.

For solving, we can use Gaussian elimination. The solution is: x₁ = s, x₂ = t, x₃ = u - (3/2)v, x₄ = v, x₅ = w, where s, t, u, v, and w are real numbers, representing the parametric or parametric vector form of the solution.

The given system of linear equations can be represented in matrix form as AX = B, where A is the coefficient matrix, X is the vector of variables, and B is the vector of constants. Using Gaussian elimination or row reduction, we can transform the augmented matrix [A | B] into row-echelon form or reduced row-echelon form.

Performing the necessary row operations, we obtain the following row-echelon form:

1 -6 -4 10 2 | 3

0 7 7 -18 0 | 0

0 0 -4 6 -1 | 1

0 0 0 0 0 | 0

From the row-echelon form, we can deduce the parametric or parametric vector form of the solution. Assigning parameters to the free variables, we have:

x₁ = s

x₂ = t

x₃ = u - (3/2)v

x₄ = v

x₅ = w

Therefore, the solution to the given system of linear equations is:

x₁ = s

x₂ = t

x₃ = u - (3/2)v

x₄ = v

x₅ = w, where s, t, u, v, and w are real numbers, representing the parametric or parametric vector form of the solution.

There is no mode for the following data.

Step-by-step explanation:

This is because the mode is the  value which occurs most frequently in a data set. yet there is not a piece of data that appears the most frequently.  

The mode of this data set is the Independents.

The mode is a statistical term that refers to the value that appears most frequently in a data set. In this case, you have provided data on the number of Republicans, Democrats, and Independents. There are 47 Republicans, 49 Democrats, and 52 Independents.

To determine the mode, we simply look for the highest count among the three groups. In this case, we can see that the group with the highest count is the Independents with a count of 52.

Therefore, the mode of this data set is the Independents. This tells us that Independents are the most frequent group in this particular data set. Remember, the mode is just one way to describe the central tendency of data and should be considered alongside other measures like the mean and median for a more comprehensive understanding of the data distribution.
