A farmer wants to fence an area of 750 000 m² in a rectangular field and divide it in half with a fence parallel to one of the sides of the rectangle. How can this be done so as to minimize the cost of the fence?

Answers

Answer 1

The farmer should construct a rectangle that is twice as long as it is wide, with dimensions of 1216.56 m x 608.28 m, and should use 7301.36 m of fence to divide it in half parallel to the shorter side in order to minimize the cost of the fence.

To minimize the cost of the fence, the farmer should construct a rectangle that is twice as long as it is wide, with the dividing fence parallel to the shorter side. This will result in two identical rectangles each with an area of 375 000 m².

The perimeter of the rectangle can be calculated as follows:

P = 2L + 2W

where L is the length and W is the width.

Since the area of the rectangle is 750 000 m² and the length is twice the width, we can write:

L x W = 750 000

L = 2W

Substituting L = 2W into the equation for area, we get:

2W x W = 750 000

2W² = 750 000

W² = 375 000

W = 608.28 m

L = 2W = 1216.56 m

So the dimensions of the rectangle are 1216.56 m x 608.28 m.

The perimeter of each rectangle is:

P = 2L + 2W

P = 2(1216.56) + 2(608.28)

P = 3650.68 m

The total length of fence needed is twice the perimeter, since we are dividing the rectangle in half:

Total fence length = 2 x 3650.68 = 7301.36 m

What is the max/min of the quadratic equation in factored form: f(x) = 0. 5(x+3)(x-7)? Is it a maximum or a minimum? Show your workor explain your reasoning. ​

Answers

The quadratic equation in factored form: f(x) = 0. 5(x+3)(x-7) have a minimum point. The minimum value of the function is -11.

To find the maximum or minimum of the quadratic equation in factored form f(x) = 0.5(x+3)(x-7), we need to convert it to standard form by expanding the terms:

f(x) = 0.5(x² - 4x - 21)

f(x) = 0.5x² - 2x - 10.5

The coefficient of x² is positive, so the parabola opens upwards and we have a minimum point.

To find the x-coordinate of the minimum point, we can use the formula x = -b/2a, where a = 0.5 and b = -2:

x = -(-2)/2(0.5) = 2

So the minimum point is at x = 2. To find the y-coordinate, we can substitute x = 2 into the equation:

f(2) = 0.5(2)^2 - 2(2) - 10.5 = -11

Therefore, the minimum value of the function is -11.

Sofia owns a small business selling ice cream. She knows that in the last week 56 customers paid cash, 6 customers used a debit card, and 18 customers used a credit card.



Based on these results, express the probability that the next customer will pay with a credit card as a fraction in simplest form

Answers

The probability that the next customer will pay with a credit card is 9/40.

To find the probability that the next customer will pay with a credit card, we need to determine the total number of customers and then calculate the fraction of those who used a credit card.

Step 1: Find the total number of customers.
56 customers paid cash, 6 customers used a debit card, and 18 customers used a credit card.
Total customers = 56 + 6 + 18 = 80 customers

Step 2: Calculate the probability of a customer using a credit card.
Number of customers who used a credit card = 18
Total number of customers = 80


Probability = (Number of customers who used a credit card) / (Total number of customers)
Probability = 18 / 80

Step 3: Simplify the fraction.


Divide both the numerator and denominator by their greatest common divisor (GCD). The GCD of 18 and 80 is 2.
18 ÷ 2 = 9
80 ÷ 2 = 40

Simplified fraction: 9/40

So, the probability that the next customer will pay with a credit card is 9/40.

a pet store has 115 fish and each tank can hold six fish how many tanks do you nedd

Answers

Answer:

20 tanks

Step-by-step explanation:

if each tank holds 6 fish and there are 115 fish, you need to divide the amount of fish total by amount that go in 1 tank:

115/6 = 19.1666666667

Now we round up bc we cant leave any fish out right?

So your answer is 20 tanks will be needed to hold 115 fish if it’s 6 fish per tank.

Check this by multiplying the tanks and fish in every tank:

20 x 6 = 120

Meaning that 115 fish go into 20 tanks, one of the tanks just having 1 fish :D

Answer: 20 is the correct option.

Step-by-step explanation:Given that a pet store has 115 fish that need to be placed into fish tanks and each tank hold 6 fish.

We are to find the number of tanks that the store need.

We will be using the UNITARY method to solve the given problem.

Number of tanks needed to store 6 fishes = 1.

So, number of tanks needed to store 1 fish will be [tex]\frac{1}{6}[/tex]

Therefore, number of tanks needed to store 115 fishes is given by

[tex]\frac{1}{6}[/tex] × 155 =[tex]\frac{115}{6}[/tex]= 19 [tex]\frac{1}{6}[/tex] = 19.16.

Since we cannot have 0.16 tank, so we need one tank more than 19 to store all fishes.

Thus, the store needs 20 tanks for 115 fishes.

might Frank have made?


The area enclosed by the figure is


m2


(Round to the nearest hundredth as needed. )

Answers

To find the area enclosed by the figure, we first need to find the area of  the square and the  area of each semicircle.

The area of the square is simply the length of one of its sides squared, which is:

54 m x 54 m = 2,916 m²

The area of each semicircle is half the area of a full circle with the same radius as the side of the square. The radius of each semicircle is 54 m/2 = 27 m.

The area of each semicircle is:

1/2 x π x 27 m² = 1/2 x 3.14 x 27 m x 27 m ≈ 1,442.31 m²

Since there are four semicircles, the total area of the semicircles is:

4 x 1,442.31 m² = 5,769.24 m²

Therefore, the total area enclosed by the figure is:

2,916 m² + 5,769.24 m² ≈ 8,685.24 m²

Frank's answer of 1,662.12 m² is significantly less than the actual area. He may have made the mistake of only calculating the area of one of the semicircles instead of all four, or he may have forgotten to include the area of the square.

How many AP classes is the new student taking?

A) 2
B) 3
C) 4
D) 5

Answers

Answer:

2

Step-by-step explanation:

To solve this problem, we need to first find the current average and median number of AP classes per student, and then use that information to determine the number of AP classes the new student is taking.

To find the current average number of AP classes per student, we can use the information in the table:

(1 AP class) x 6 students = 6 AP classes

(2 AP classes) x 9 students = 18 AP classes

(3 AP classes) x 5 students = 15 AP classes

(4 AP classes) x 4 students = 16 AP classes

Total number of AP classes = 6 + 18 + 15 + 16 = 55

Total number of students = 6 + 9 + 5 + 4 = 24

Average number of AP classes per student = Total number of AP classes / Total number of students

= 55 / 24

= 2.29 (rounded to two decimal places)

To find the current median number of AP classes per student, we need to order the number of AP classes per student from least to greatest:

1, 1, 1, 1, 1, 1, 2, 2, 2, 2, 2, 2, 2, 2, 2, 3, 3, 3, 3, 3, 4, 4, 4, 4

The median is the middle value when the data is ordered in this way. Since there are 24 students, the median is the average of the 12th and 13th values:

Median = (2 + 2) / 2

= 2

Since we know that the current average and median are not equal, the new student must be taking a number of AP classes that will bring the average up to 2. We can set up an equation to represent this:

(55 + x) / (24 + 1) = 2

where x is the number of AP classes the new student is taking. Solving for x, we get:

55 + x = 50

x = -5

This is a nonsensical answer, as the number of AP classes taken by the new student cannot be negative. Therefore, our assumption that the new student is taking a number of AP classes greater than the current average is incorrect. Instead, the new student must be taking a number of AP classes less than the current average, which will bring the average down to 2.

Let y be the number of AP classes the new student is taking. We can set up a new equation to represent this:

(55 + y) / (24 + 1) = 2 - ((2.29 - 2) / 2)

where the term on the right-hand side represents the amount by which the average needs to decrease in order to reach 2. Solving for y, we get:

55 + y = 46.5

y = 46.5 - 55

y = 8.5

So the new student is taking 8.5 AP classes. However, since the number of AP classes must be a whole number, we need to round this value to the nearest integer. Since 8.5 is closer to 9 than to 8, we round up to 9. Therefore, the answer is:

The new student is taking 9 AP classes. Answer: None of the above (not given as an option).

8 pound of peanuts cost 24 dollars. 6 pounds of walnuts cost half as much. Which is more expensive and by how much.

Answers

Answer:

Step-by-step explanation:

The cost of 1 pound of peanuts can be found by dividing the total cost of 8 pounds by 8:

Cost of 1 pound of peanuts = $24 / 8 pounds = $3 per pound

The cost of 1 pound of walnuts can be found by dividing the total cost of 6 pounds by 6 and then multiplying by 2 (since the cost of 6 pounds is half that of the peanuts for the same weight):

Cost of 1 pound of walnuts = ($24 / 6 pounds) x 2 = $8 per pound

Therefore, we see that walnuts are more expensive than peanuts by $5 per pound ($8 - $3).

In other words, 1 pound of walnuts costs $5 more than 1 pound of peanuts.

The question asks us to find the value of the function f(x) = 4[tex]x^3[/tex] at x = 2 and its derivative f'(x) at x = 2.

The value of the function f(x) at x = 2, we simply plug in x = 2 into the function and evaluate:

f(2) = 4[tex](2)^3[/tex] = 4(8) = 32

Therefore,

The value of the function f(x) at x = 2 is 32, which we can write as f(2) = 32.

To find the derivative of the function f(x) at x = 2, we first need to find the general formula for the derivative of f(x), which we can do using the power rule for derivatives.

The power rule states that

To find the derivative of f(x) at x = 2, we simply plug in x = 2 into the formula for f'(x) that we just found:

f'(2) = [tex]12(2)^2[/tex] = 48

Therefore,

The derivative of the function f(x) at x = 2 is 48, which we can write as f'(2) = 48To find the derivative of the function

f'(x) = 12[tex]x^2[/tex]

To find the value of f(2), we can simply plug in x = 2 into the original function:

f(2) = 4[tex](2)^3[/tex] = 32

To find the value of f'(2), we can plug in x = 2 into the derivative we just found:

Answers

The profit per pig is $4 and the profit per goose is $8.

How can the farmer raise at most 16 animals in order to maximize his profits?

Let's start by defining the variables:

a = number of pigs Farmer Jones raises

y = number of geese Farmer Jones raises

The problem tells us that he wants to raise at most 16 animals, so we can write:

a + y ≤ 16

It also tells us that he wants no more than 12 geese, so we can write:

y ≤ 12

We know that it costs $5 to raise a pig and $2 to raise a goose, and he has $550 available to spend. So the cost of raising the animals can be expressed as:

5a + 2y ≤ 550

Finally, we want to maximize his profits. The profit per pig is $4 and the profit per goose is $8. So the objective function for Farmer Jones' profits is:

Profit = 4a + 8y

To summarize, the linear programming model for this problem is:

It takes an apprentice four times as long as the experienced plumber to replace the pipes under an old house. If it takes them 15 hours when they work together, how long would it take the apprentice alone?

Answers



Let's assume that the experienced plumber can complete the job in x hours.

According to the problem, the apprentice takes four times as long as the experienced plumber to complete the job. Therefore, the apprentice can complete the same job in 4x hours.

If they work together, they can complete the job in 15 hours. Therefore, we can write the following equation based on their combined work rate:

1/x + 1/4x = 1/15

Multiplying both sides by the common denominator of 60x gives:

60 + 15 = 4x

75 = 4x

x = 75/4

x = 18.75

Therefore, the experienced plumber can complete the job in 18.75 hours.

Using the relationship that the apprentice takes four times as long as the experienced plumber to complete the job, we can find the time it takes for the apprentice to complete the job alone:

4x = 4(18.75) = 75

Therefore, the apprentice would take 75 hours to complete the job alone.

z + x =9....(3) we can say it's x + z = 9

x - z = - 1

x + z = 9

______ -

- 2z= - 10

z = 10/2

z = 5

if z + x = 9

5 + x = 9

x = 9 - 5

x = 4

if x + y = 5

4 + y = 5

y = 5 - 4

y = 1

The total cost C(x) (in dollars) incurred by Aloha Company in manufacturing x surfboards a day is given by the following function.
C(x) = −10x2 + 500x + 110 where (0 ≤ x ≤ 15)
(a)
Find C '(x).
C '(x) = (b)
What is the rate of change of the total cost (in dollars) when the level of production is 7 surfboards a day?
$ per surfboard

Answers

(a) First, we need to find the derivative of the cost function, C'(x), with respect to x.

The given function is: C(x) = -10x^2 + 500x + 110

To find the derivative, we will apply the power rule:

C'(x) = d/dx (-10x^2) + d/dx (500x) + d/dx (110)

For each term: d/dx (-10x^2) = -20x d/dx (500x) = 500 d/dx (110) = 0 So, C'(x) = -20x + 500

(b) Now, we need to find the rate of change of the total cost when the level of production is 7 surfboards a day.

To do this, we will substitute x=7 into the derivative function C'(x): C'(7) = -20(7) + 500 C'(7) = -140 + 500 C'(7) = 360

The rate of change of the total cost when the level of production is 7 surfboards a day is $360 per surfboard.

Your answer: a) C'(x) = -20x + 500 b) $360 per surfboard

Find the measure of Tu in the photo

Answers

The value of the tangent TU for the circle with secant through U which intersect the circle at points V and W is equal to 12

What are circle theorems

Circle theorems are a set of rules that apply to circles and their constituent parts, such as chords, tangents, secants, and arcs. These rules describe the relationships between the different parts of a circle and can be used to solve problems involving circles.

For the tangent TU and the secant through U which intersect the circle at points V and W;

TU² = UV × VW {secant tangent segments}

(5x)² = 9 × 16

(5x)² = 144

5x = √144 {take square root of both sides}

5x = 12

x = 12/5

so;

TU = 5(12/5)

TU = 12

Therefore, the value of the tangent TU for the circle with secant through U which intersect the circle at points V and W is equal to 12

Answers

The term which is important in terms of making meaning of those scores is measures of central tendency (mean, median, mode), option A.

A single number that seeks to characterise a set of data by pinpointing the centre location within that set of data is referred to as a measure of central tendency. As a result, measurements of central location are occasionally used to refer to measures of central tendency.

These also fit within the category of summary statistics. You are probably most familiar with the mean (sometimes known as the average), but there are additional central tendency measures, including the median and the mode.

The mean, median, and mode are all reliable indicators of central tendency, however depending on the situation, certain indicators are more useful than others.
