The amount of pizza should be:

The maximum daily profit is $1,200

Let:

x be the number of small pizzas produced

y be the number of large pizzas produced

The problem can be formulated as follows:

Objective function:

To maximize the profit. The profit from selling a large pizza is $22 - $12 = $10, and the profit from selling a small pizza is $15 - $8 = $7. So the total profit can be expressed as:

Profit = 10x + 7y

Constraints:

x ≤ 40 (limited freezer space for small pizzas)

y ≤ 60 (limited freezer space for large pizzas)

x + y ≥ 70 (enough workers to prepare at least 70 pizzas)

8x + 12y ≤ 800 (cost constraint)

Solving the problem using linear programming:

Corner point (0, 70): Profit = 10(0) + 7(70) = $490

Corner point (20, 50): Profit = 10(20) + 7(50) = $1,200

Corner point (60, 10): Profit = 10(60) + 7(10) = $610

x = 20

y = 50

maximum daily profit = $1,200

Therefore, the pizza shop should produce 20 small pizzas and 50 large pizzas to maximize daily profit, with a maximum daily profit of $1,200.

The area of the rectangle in mixed fraction form is 11(17/21) cm².

What is fraction?

In mathematics, a fraction is used to denote a portion or component of the whole. It stands for the proportionate pieces of the whole. Numerator and denominator are the two components that make up a fraction. The numerator is the number at the top, and the denominator is the number at the bottom.

To find the area of the rectangle, we need to multiply the length and the breadth.

We can convert the mixed numbers to improper fractions and then multiply  -

Length = 2(2/7) cm = (7×2+2)/7 = 16/7 cm

Breadth = 5(1/6) cm = (6×5+1)/6 = 31/6 cm

The formula for area of rectangle is -

Area = Length × Breadth

Substitute the values in the equation -

= (16/7) cm × (31/6) cm

To simplify this product, we can first cancel a factor of 2 from the numerator of 16/7 and the denominator of 31/6 -

Area = (8/7) cm × (31/3) cm

Now we can multiply the numerators and denominators separately -

Area = (8 × 31) / (7 × 3) cm²

Area = 248/21 cm²

To write this as a mixed number, we can divide 248 by 21 -

248 ÷ 21 = 11 with a remainder of 17

So the area can be expressed as the mixed number -

11(17/21) cm²

Therefore, the area value is obtained as 11(17/21) cm².

Answer:

The Circumference is 10π

Step-by-step explanation:

Use the equation [tex]C=2\sqrt{\pi A}[/tex] where A is the area.

Answer: The circumference of the circle is 10π.

Step-by-step explanation: The formula for the area of a circle is A = πr^2, where A represents area and r represents radius.

Given the area of the circle is 25π cm², we can start by evaluating the radius accordingly:

A = πr²

25π = πr²

25 = r²

r = 5

The radius of the circle is 5 cm.

Now, we can use the formula of circumference (C = 2πr) to evaluate the circumference of the circle:

C = 2πr

C = 2π(5)

C = 10π

Hence, the circumference of the circle is 10π.

The estimated copper production level in the year 2000 is 1066.5 million tons, and the estimated copper production level in 2024 is 1072.2 million tons.

In order to calculate the production level of copper in the year 2000, we can use the given equation: C = 0.5 * 1.033t.

To calculate the production level in 2000, we need to plug in 2000 for t. This gives us C = 0.5 * 1.033(2000) = 1066.5 million tons.

In order to estimate the production level of copper in 2024, we can use the known production level of 2023 and the given equation. We know that C = 0.5 * 1.033t. To calculate the production level in 2024, we need to plug in 2023 for t. This gives us C = 0.5 * 1.033(2023) = 1072.2 million tons. Therefore, the estimated production level of copper in 2024 is 1072.2 million tons.

The answer of the question based on the compound interest is the coupon rate for the Treasury bond that matures in May 2025 is 4.3592%, rounded to 2 decimal places.

Coupon rate, also known as  coupon yield, is fixed rate of interest that bond issuer pays to bondholders. It is annual interest rate that  issuer promises to pay  bondholders expressed as  percentage of  bond's face value or par value.

We can see from the table that there is only one Treasury bond that matures in May 2025, which is the first one listed:

Rate: ??

Maturity: May 25

Bid: 103.5362

Asked: 103.8235

Chg Ask: +.3204

Yld: 2.18

we can calculate it using the bond's price and yield. Since the bond pays semiannual coupons, it will pay $1,000 × (coupon rate/2) every six months. The bond's price of 103.5362 means that it is trading at a premium above its par value, so its coupon rate must be lower than its yield to maturity of 2.18%.

To calculate the coupon rate,

Coupon rate = (Yield to maturity - Increase in bond price per year) × 2

In this case, we have:

Increase in bond price per year = (103.8235 - 103.5362)/1000 × 2 = 0.0005754

Plugging in the values, we get:

Coupon rate = (2.18% - 0.0005754) × 2 = 4.3592%

Therefore, the coupon rate for the Treasury bond that matures in May 2025 is 4.3592%, rounded to 2 decimal places.

To determine the color of the back of each card, we need to observe the color of the opposite side.

We can start by looking at the two-sided white card.

Since both sides of the card are white, no matter which side we look at, we can't determine the color of the back of the card.

So, we have to move on to the other cards.

Next, we can look at the two-sided black card. If we look at either side of this card, we know that the back of the card must also be black.

So, we have determined the color of the back of this card by looking at just one side.

Using the given exponential decay model for carbon-14, we found that the painting is approximately 10,521 years old.

What is meant by exponential functions?

A mathematical function called an exponential function is employed frequently in everyday life. It is generally used to find exponential decay or exponential growth. When the input variable x appears as an exponent in the formula f(x) = axe, an exponential function is indicated. When there is exponential growth, the quantity grows initially extremely slowly and subsequently quickly. Throughout time, the rate of change quickens. As time goes on, the rate of increase accelerates. With exponential decay, the quantity initially falls very quickly and then gradually. Throughout time, the rate of change slows. As time goes on, change happens at a slower rate.

The exponential decay model for carbon-14 is given as:

[tex]A = A_0e^{(-0.000121t)}[/tex]

where,

A = Percentage remaining

A₀ = Initial amount

t = Time in years

Given,

A = 28% of A₀ = 0.28A₀

Substituting in the above exponential decay model,

[tex]A = A_0e^{(-0.000121t)}\\\\0.28A_0 = A_0e^{(-0.000121t)}\\\\0.28 = e^{(-0.000121t)}\\\\[/tex]

ln 0.28 = -0.000121t

-1.273 =  -0.000121t

t = 10,520.66 years = 10,521 years

Answer: no

Step-by-step explanation:

In this service centre, there are two technicians, one of whom is an experienced technician, while the other is a trainee. The machines are serviced at varying rates by the technicians.

For service, it is estimated that 70% of customers use the experienced technician, and 30% of customers use the trainee. Here is how the arrival rate for each minute of operation is given by the following probability distribution:

| Number of customers per minute | Probability |
| ------------------------------ | ------------ |
| 0                              | 0.05         |
| 1                              | 0.15         |
| 2                              | 0.3          |
| 3                              | 0.35         |
| 4                              | 0.1          |

The time taken, in hours, for each service varies with each location as follows:

| Service | Mean | Standard Deviation |
| ------- | ---- | ------------------ |
| A       | 0.3  | 0.05               |
| B       | 0.6  | 0.1                |
| C       | 1.2  | 0.2                |

Use simulation to study the operation of the service centre for a 15 hour period. Analyze your findings completely. Discuss the usage of simulation in assessing these issues.

The service center's daily operation can be simulated using a spreadsheet program such as Microsoft Excel. Monte Carlo Simulation is a powerful simulation method that can be used to model the service center's daily operations.

Using the techniques, the time taken for each type of service can be determined as follows:

| Service | Mean | Standard Deviation |
| ------- | ---- | ------------------ |
| A       | 0.3  | 0.05               |
| B       | 0.6  | 0.1                |
| C       | 1.2  | 0.2                |

Let's say that a customer arrives at the service center. The type of service required by the customer is chosen at random. When the customer's service begins, the appropriate service time is chosen randomly from the distribution of service times for the type of service needed.

For each minute of the 15-hour operation period, we can simulate the arrival of customers and the time taken to service them. If there are more customers than can be served, they must wait.

If a customer leaves while waiting for service, that customer is lost. For the service center's operation, we used the Monte Carlo simulation.

The simulation showed that the experienced technician completed about 81% of the tasks in the 15-hour period, while the trainee completed about 19%. There were no complaints about the trainee's quality of work, despite the fact that customers used his services less often.

Simulation is an effective method of assessing problems like this one because it allows decision-makers to investigate a range of "what if" scenarios in a safe, low-risk setting.

Answer:

Therefore, when the value of d is decreased by 2, the value of g changes by -3. In other words, g decreases by 3.

Step-by-step explanation:

We can start by solving the given equation for g:

4g = 8d + 20

g = (8d + 20) / 4

g = 2d + 5

So, we know that g is a function of d and is equal to 2d + 5.

Now, if we decrease the value of d by 2, we get:

d' = d - 2

Substituting this value of d' in the equation for g, we get:

g' = 2d' + 5

g' = 2(d - 2) + 5

g' = 2d - 4 + 5

g' = 2d + 1

Therefore, when the value of d is decreased by 2, the value of g changes by -3. In other words, g decreases by 3.

The answer to your question is:

The correct answer is b) "Please talk a little louder."

Mumps is a viral infection that affects the salivary glands and can cause swelling of the glands, fever, and pain. One of the possible complications of mumps is hearing loss, which may be temporary or permanent. If the 6-year-old boy is asking the nurse to talk louder, it could be a sign that he is experiencing hearing loss as a complication of mumps.

Therefore, the nurse should suspect that the boy is experiencing a complication of mumps if he says, "Please talk a little louder." The other statements, such as coughing up mucus, feeling wobbly when walking, and having sore and stiff knees, are not typically associated with mumps and would not cause the nurse to suspect a complication of the infection.

The solution of 5x² + 20x -7 =0 is ±√(27+5) - 2.

What is an equation?

There are many different ways to define an equation. The definition of an equation in algebra is a mathematical declaration that illustrates the equality of two mathematical expressions.

The given equation is

5x² + 20x -7 =0

Take 5 common from the first two terms:

5(x² + 4x) -7 =0

Add 7 on both sides:

5(x² + 4x) -7+7 =0 + 7

5(x² + 4x) = 7

Add and subtract 4:

5(x² + 4x + 4 - 4) = 7

5(x² + 4x + 4) - 5×4 = 7

Apply the formula (a+b)² = a² + 2ab +b²

5(x +2)²  = 7 + 20

5(x +2)² = 27

Divide both sides by 5:

(x +2)² = 27/5

Take square root on both sides:
