The largest area possible is when the length and width of the chicken pen are both 100 feet. In that case, the area of the chicken pen would be 10,000 square feet.

We are given that the farmer has 200 feet of fencing to build a rectangular chicken pen along the side of a barn. We need to find the largest possible area the chicken pen can have.

To do this, we need to find the length and width of the chicken pen such that the total amount of fencing used is 200 feet.

Since the total amount of fencing needed is 200 feet, the length and width of the chicken pen must both be 100 feet. In this case, the area of the chicken pen would be 10,000 square feet.

Therefore, the largest area possible is 10,000 square feet when the length and width of the chicken pen are both 100 feet.

Option - B : Decision support system is a flexible tool for data analysis, since its reports do not have a fixed format.

  Decision support systems, a subset of business intelligence, are created to help organisations make sensible business decisions based on vast volumes of analysed data. Huge volumes of data are analysed using an interactive information system called a decision support system (DSS) to aid in the direction of business choices. A DSS aids management, operations, and planning levels of an organisation in making better decisions by assessing the importance of uncertainties and the tradeoffs involved in selecting one option over another. A DSS uses a variety of raw data, papers, personal knowledge, and/or business models to aid users in making decisions. A DSS may make use of relational data sources, cubes, data warehouses, electronic health records (EHRs), income projections, sales projections, and other sources.

The mean, median, mode and the mean of the extra ten rolls are  

 2.96,2.5,1 and 2.9 respectively  

The mean represents the average of the dataset, the median represents the middle value of the data set, and the mode represents the repeated value in the dataset.

Using the given information we construct the following table

Score     frequency           Cumulative Frequency  (frequency*score)

1                 15                          15                                      15

6                 7                           50                                      42

thus N= 50 (even) The Median is the average of the 25th and 26th observations. The 25th and 26th observations corresponds to the value 3.

The Median is = 2.5

The modal score = 1

Mode = 3×(median) – 2×(mean)

mean = 2.96

The mean score for the 60 roles is 2.95×60 = 148+sum of the extra ten

To find the amount of red and white that Peter needs to add to the large batch, we can set up the following proportion:

(3/5 qt red) : (1 qt blue) : (2/5 qt white) = (x qt red) : (15 qt blue) : (y qt white)

The proportion states that the ratio of red to blue to white in the test batch is equal to the ratio of red to blue to white in the large batch.

Cross-multiplying and solving for x and y gives us:

(3/5)x = 15y

(2/5)y = 15x

Solving the first equation for y and substituting it into the second equation gives us:

(2/5)y = 15x

(2/5)(15x/3) = 15x

x = 9 qt

Substituting this value for x back into the first equation gives us:

(3/5)x = 15y

(3/5)(9 qt) = 15y

y = 6 qt

Therefore, Peter needs to add 9 qt of red and 6 qt of white to the large batch to make it the same color as the test batch.

Answer: 26, 28, 30

Explanation:

Let's define a variable x to represent the least of the three consecutive even integers. This means that the three integers are x, x + 2, and x + 4.

We can write the given information as an equation:

3 * (x + 4) = 2 * x + 38

We can solve for x by moving all the terms with x to one side of the equation and all the other terms to the other side:

3 * (x + 4) - 2 * x = 38

Then we can distribute the 3 and the -2 to get:

3 * x + 12 - 2 * x = 38

And then we can combine like terms on each side of the equation:

x + 12 = 38

Finally, we can subtract 12 from both sides to solve for x:

x = 26

Therefore, the three consecutive even integers are 26, 28, and 30.

We can check our solution by substituting these values back into the original equation and verifying that it holds true:

3 * (26 + 4) = 2 * 26 + 38

3 * 30 = 52 + 38

90 = 90

The equation holds true, so our solution is correct.

In this case, the amount of population of fruit flies doubled in 18 days, meaning the doubling time is 9.5 days.

The doubling time of a population is the amount of time it takes for a population to double in size. In this case, the population of fruit flies started at 182 individuals and grew to 340 in 18 days. To calculate the doubling time, we used the equation (182 x 2^(18/9.5)) = 340, where the 2^(18/9.5) is the exponentiation of the number of days divided by the doubling time. This equation can be rearranged to solve for the doubling time, yielding a result of 9.5 days. This means that the population of fruit flies doubled in size every 9.5 days, which is the doubling time of the population.

It will cost $225 to pour 25 yd3 of concrete with 3 workers working at a rate of $15 per hour.

To determine the cost to pour 25 yd3 of concrete, you can use the following formula:

cost = (number of workers * worker rate per hour * number of hours)

In this case, the number of workers is 3, the worker rate per hour is $15, and the number of hours can be calculated by dividing the volume of concrete to be poured (25 yd3) by the rate at which the workers can pour concrete (5 yd3 per hour). Therefore, the number of hours it will take to pour 25 yd3 of concrete is 25/5=5 hours.

Plugging these values into the formula gives:

Answer:2.4

Step-by-step explanation:

Answer:

Let x be the shorter side of the rectangular house. Since the length of the house is two-and-a-half times its width, we can write this as 2.5x. The area of a rectangle is given by the formula length * width, so the area of the rectangular house in terms of x is 2.5x * x = 2.5x^2. This is the expression for the area of the rectangular house in terms of the shorter side x.

Answer:

[tex]2.5x^2[/tex]

Step-by-step explanation:

Let x be the shorter side of the rectangle, which is also its width (w), so:

[tex]w=x[/tex]

Given that the length of the rectangle is two-and-a-half times its width, this means the length (l) can be expressed as:

[tex]l=2.5x[/tex]

The area of a rectangle (A) is the product of its length (l) and width (w):

[tex]A =l \cdot w[/tex]

Substitute the expressions for length and width into the formula for area:

[tex]A=2.5x \cdot x[/tex]

Simplify this expression:

[tex]A=2.5x^2[/tex]

Therefore, the expression for the area of the rectangle in terms of x is:

In calculation, the precise bisector is a line section that separates a point into two equivalent points and parts.

The measure of P Q R is equal to the sum of ∠PQT and ∠TQR if line segment QT is the angular bisector of an angle ∠PQR.

∠PQR is equal to ∠PQT + ∠TQR.

There are three angular bisectors that can be made in a triangle, and all of them meet at the incenter of the triangle because line Q T is the angular bisector of P Q R. As a result, P Q T = T Q R.

BD divides ABC into two angles, ABD and DBC, given that line.

Additionally, given that DBC = 20 x + 16

ABD = 12 x + 24

Therefore, A B C = ABD + DBC (1) and ABD = DBC (2) respectively.

According to the second equation, 12 x + 24 = 20 x + 16 24  16 = 20 x 12 x 8 x = 8 x = 8 8 = 1

As a result, A B D = 12 (1) + 24; A B D = 36;

D B C = 20 (1) + 16; A B C = 36.

As a result of the equation (1), A B C = A B D + D B C;

The commutative property of addition justifies step 1 and the substraction of the property of equality justifies step 3.

What is the Substitution Property of Equality?

The substitution property of equality is applied by replacing a variable with a number or quantity. For example, if we have:

5x + 3 = 18, if x = 3, we can substitute x = 3 into the equation by applying the substitution property of equality as shown below:

5(3) + 3 = 18

15 + 3 = 18

18 = 18.

We have,

0.4x + 5 + 0.2x = 17

Step 1 : 0.4x + 0.2x + 5 = 17

commutative property of addition

Step 2: 0.6x + 5 = 17

Step 3: 0.6x = 12

substraction of property of equality

so, step 1  :  commutative property of addition

Step 3 : substraction of property of equality

Hence, the commutative property of addition justify for step 1 and the substraction of the property of equality justify for step 3.

Answer:

You must babysit for 8 weeks to earn enough money to buy the new gaming chair.

Step-by-step explanation:

To determine how many weeks you must babysit to earn enough money to buy the new gaming chair, we need to write and solve an equation that represents the relationship between the money you have saved, the money you earn each week, and the cost of the gaming chair.

First, we can let w represent the number of weeks you must babysit. Then, we can set up the equation:

Earnings + Savings = Total Cost

Substituting the known values into the equation, we have:

Earnings + Savings = Total Cost

$37.50w + $155.95 = $455.95

To solve the equation, we can first subtract $155.95 from both sides of the equation:

$37.50w + $155.95 - $155.95 = $455.95 - $155.95

$37.50w = $300.00

Next, we can divide both sides of the equation by $37.50 to find the value of w:

$37.50w / $37.50 = $300.00 / $37.50

w = 8

Therefore, you must babysit for 8 weeks to earn enough money to buy the new gaming chair.

What is probability ?

The area of mathematics known as probability deals with numerical descriptions of how likely it is for an event to happen or for a claim to be true. A number between 0 and 1 is the probability of an event, where, broadly speaking, 0 denotes the event's impossibility and 1 denotes its certainty.

A probability is a number that expresses the possibility or likelihood that a specific event will take place. Probabilities can be stated as proportions with a range of 0 to 1, or as percentages with a range of 0% to 100%.

A probability is the number of desired outcomes divided by the number of total outcomes.

Answer:

I believe the answer is the first one.

Step-by-step explanation:

The domain of a function is the lowest X value to the highest X value. The range of a function is the lowest Y value to the highest Y value. Since this question is asking about the domain, we can narrow down the answers to either 1, or 2 because 3 and 4 are for the range, with Y in them.

Next, we look at the points. The differences between them is that 1 has greater OR EQUAL and less than OR EQUAL, whereas 2 has just greater or less then. The circles are filled in on the graph, meaning they are closed. this means it could be equal. Since we know the equation must contain equals in it, we can eliminate 2 and 4 because they only have greater and less than signs.

This leaves the only correct answer for the domain of the graph to be 1.

The domain is the interval of x thus {x | −4 ≤ x ≤ 3} will be the domain so option (A) is correct.

A function's range is the set of all values that the function accepts, and its domain is the set of all values for which the function is defined.

The domain is for the independent variable while the range is for the dependent variable.

As per the given linear function,

The domain is the set of x that the function defines.

Since (-4,9) is a closed circle so -4 will be included and (3,-5) is also a closed circle thus 3 will also be included.

So the interval will be as {x | −4 ≤ x ≤ 3}.

Hence "The domain is the interval of x thus {x | −4 ≤ x ≤ 3} will be the domain".

in Right triangles you can use this formula to find altitude by using two parts which altitude has made on the base

H² = b¹ × b²

So using this formula (which can be proven by triangle similarity) can help us to find x

10² = 4x × x ===>> x =5
