Raphael went to the store and bought 2 12 pounds of chicken breasts for $9.00. The chicken breasts cost $
per pound. Round your answer to the nearest cent, if necessary.
Answer:
Raphael spent $0.38 per pound of chicken
Step-by-step explanation:
Because Raphael bought 2 packages weighing 12 pounds each you have to multiply 2 by 12 to get the total weight which is 24.
the math would be for this equation $9.00/24=0.375
you round up the thousandths place and get $0.38 per pound of chicken

In your reservoir, you have a production well which flows for 48 hours at 200 STB/day, and then shut-in for 24 hours. The following additional data are given : Pi = 3100 psi Ct = 15x10^-6 psi^-1 Bo = 1.3 bbl/STB ϕ = 15% μ=1.2 cp K = 45 md and h = 60 ft
a-) Calculate the pressure in this production well at 12 hours of shut in
b-) Explain how can you use superposition in time to analyze a pressure build-up test.
a) To calculate the pressure at 12 hours of shut-in:
substitute the given values into the pressure buildup equation and solve for P(t=12).
b) Superposition in time is used in pressure buildup analysis by adding or summing the responses of multiple transient tests to analyze and interpret reservoir behavior and properties.
We have,
a) To calculate the pressure in the production well at 12 hours of a shut-in, we can use the equation for pressure transient analysis during shut-in periods, known as the pressure buildup equation:
P(t) = Pi + (Q / (4πKh)) * log((0.14ϕμCt(t + Δt)) / (Bo(ΔP + Δt)))
Where:
P(t) = Pressure at time t
Pi = Initial reservoir pressure
Q = Flow rate
K = Permeability
h = Reservoir thickness
ϕ = Porosity
μ = Viscosity
Ct = Total compressibility
t = Shut-in time (12 hours)
Δt = Time since the start of the flow period
Bo = Oil formation volume factor
ΔP = Pressure drop during the flow period
Given:
Pi = 3100 psi
Q = 200 STB/day
K = 45 md
h = 60 ft
ϕ = 15%
μ = 1.2 cp
Ct = 15x10^-6 psi^-1
Bo = 1.3 bbl/STB
t = 12 hours
Δt = 48 hours
ΔP = Pi - P(t=Δt) = Pi - (Q / (4πKh)) * log((0.14ϕμCt(Δt + Δt)) / (Bo(ΔP + Δt)))
Substituting the given values into the equation:
ΔP = 3100 - (200 / (4π * 45 * 60)) * log((0.14 * 0.15 * 1.2 * 15x[tex]10^{-6}[/tex] * (48 + 48)) / (1.3 * (3100 - (200 / (4π * 45 * 60)) * log((0.14 * 0.15 * 1.2 * 15 x [tex]10^{-6}[/tex] * (48 + 48)) / (1.3 * (0 + 48))))))
After evaluating the equation, we can find the pressure in the production well at 12 hours of shut-in.
b) Superposition in time is a principle used in pressure transient analysis to analyze and interpret pressure build-up tests.
It involves adding or superimposing the responses of multiple transient tests to simulate the pressure behavior of a reservoir.
The principle of superposition states that the response of a reservoir to a series of pressure changes is the sum of the individual responses to each change.
Superposition allows us to combine the information obtained from multiple tests and obtain a more comprehensive understanding of the reservoir's behavior and properties.
It is a powerful technique used in reservoir engineering to optimize production strategies and make informed decisions regarding reservoir management.
Thus,
a) To calculate the pressure at 12 hours of shut-in:
substitute the given values into the pressure buildup equation and solve for P(t=12).
b) Superposition in time is used in pressure buildup analysis by adding or summing the responses of multiple transient tests to analyze and interpret reservoir behavior and properties.

T/V = P/(nR)
Step-by-step explanation:
You want to find T/V from the equation PV = nRT.
SolutionT is in the numerator of the ratio you want. V is on the other side of the equation from T, so you can put V in the denominator by dividing both sides of the equation by V:
[tex]P=\dfrac{nRT}{V}[/tex]
Now, you can get the ratio T/V by itself by dividing by its coefficient:

Gross profit margin (GPM) measures the amount of gross profit (GP) generated with net sales. It gives us the company’s ability to earn profit on its inventories. Higher the ratio, more favorable it is. Compute it as follows:
Gross Profit Margin (GPM) is a metric used to calculate the percentage of gross profit earned by a business on its sales. The gross profit is calculated as revenue minus cost of goods sold (COGS), and the formula for gross profit margin is:(Gross Profit ÷ Revenue) x 100%.
The gross profit margin reveals the percentage of sales that turn into gross profit. A company with a higher gross profit margin has a better chance of generating a good profit than one with a lower gross profit margin. The gross profit margin formula allows companies to determine how much revenue is remaining to cover operating expenses and net profit. In computing gross profit margin, the following steps should be taken:
First, calculate gross profit as follows: Revenue - Cost of Goods Sold (COGS) = Gross Profit.
Then, use this formula to compute gross profit margin: Gross Profit ÷ Revenue x 100%.
The gross profit margin is an important ratio used to assess a company's profitability. It is important because it reflects the percentage of sales that contribute to covering operating expenses and generating net profits. A higher gross profit margin ratio indicates that a company is earning enough on sales to cover its operating expenses and generate profits.However, one of the major drawbacks of using gross profit margin as a profitability metric is that it does not account for operating expenses. This is why it is important to calculate other profitability metrics, such as operating profit margin, to gain a complete picture of a company's profitability.It is also important to compare gross profit margins over time and with industry averages to determine how a company is performing relative to its peers. A declining gross profit margin may indicate increasing costs, pricing pressures, or a shift in product mix. Conversely, an increasing gross profit margin may suggest that the company has a competitive advantage, pricing power, or is reducing its costs.
In summary, the gross profit margin measures the percentage of revenue that contributes to gross profit. A higher gross profit margin indicates that a company is earning enough on sales to cover its operating expenses and generate profits. However, it is important to compare gross profit margins over time and with industry averages to determine how a company is performing relative to its peers. Finally, it is important to use other profitability metrics, such as operating profit margin, to gain a complete picture of a company's profitability.

The side s of a square carpet is measured at 2 ft. Estimate using the Linear Approximation the maximum error in the area A of the carpet if s is accurate to 0.7 inches. (Use decimal notation. Give your answer to three decimal places.)
To estimate the maximum error in the area A of the carpet, use the Linear Approximation. Let's use a differentiable function:
f(s) = s². When s = 2 feet, A = f(s) = s² = 4 square feet.
The change in s, Δs = 0.7 inches. We can convert that to feet and get the linear approximation:Δs = 0.7 in = 0.7/12 ft = 0.05833 ft.
A better approximation of the new area A is given by
ΔA = f′(s) Δs = 2s Δs
Since f′(s) = 2s,ΔA = 2s Δs = 4 Δs.
Since s = 2 ft and Δs = 0.05833 ft, we have that the maximum error in A is given by
|ΔA| ≤ 4 Δs = 4(0.05833) = 0.2333 square feet.
Therefore, the maximum error in the area of the carpet is 0.2333 square feet.

Last year, 300 people attended the Franklin High School Drama Club s winter play. The ticket price was $8. The advisor estimates that 20 fewer people would attend for each$1 increase in ticket price. What ticket price would give the greatest income fox the Drama Club?
The ticket price that would give the greatest income for the Drama Club is $4.
Let x be the number of $1 increase in ticket price and y be the number of people who would attend the Franklin High School Drama Club’s winter play.
The formula for the number of people who would attend for each $1 increase in ticket price is:
y = -20x + 300
The formula for the income of the Drama Club is:
I = (300 - 20x)(8 + x)
I = 2400 - 160x + 300x - 20x²
I = -20x² + 140x + 2400
I = -20(x² - 7x - 120)
To maximize the income of the Drama Club, we need to find the vertex of the quadratic equation.

Triangle ECB is the image of triangle ABC after a 180º rotation around the midpoint of segment BC.
Explain why ABCD and ABEC are parallelograms.
Answer:
Because parallelograms can be divided into two equal triangles of different orientations.
Step-by-step explanation:
Rotation is a process in which a given shape or point is turned about a reference point or line to produce the image of the initial shape, both having different orientations. It is one of the types of solid transformation.
Since,
ΔCAD = ΔABC but of different orientations, then ABCD is a parallelogram.
Also,
ΔABC = ΔECB, so that ABEC is a parallelogram.
So then:
ΔCAD = ΔABC = ΔECB
Therefore, ABCD and ABEC are parallelograms.

[tex]\frac{2}{15}x = -10[/tex]
-Multiply both sides by [tex]\frac{15}{2}[/tex], which is the reciprocal of [tex]\frac{2}{15}[/tex].
[tex]x = -10 \times (\frac{15}{2})[/tex]
[tex]x = \frac{-10 \times 15}{2}[/tex]
[tex]x = \frac{-150}{2}[/tex]

what is the probability that either event will occur?
The probability that either event A or event B will occur is 2/3.
The probability that either event A or event B will occur can be calculated using the formula P(A or B) = P(A) + P(B) - P(A and B). This formula accounts for the possibility of both events A and B occurring simultaneously.
When we add the probabilities of event A and event B individually (P(A) + P(B)), we are counting the cases where both events occur twice. To avoid this double counting, we subtract the probability of both events occurring together (P(A and B)).
This can be understood through a simple example. Let's say we have two events: event A is rolling an even number on a fair six-sided die, and event B is rolling a number less than 4 on the same die.
The probability of event A occurring is P(A) = 3/6 = 1/2 (since three out of six numbers are even).
The probability of event B occurring is P(B) = 3/6 = 1/2 (since three out of six numbers are less than 4).
If we simply add P(A) + P(B) without accounting for the possibility of both events occurring together, we would get 1/2 + 1/2 = 1, which is incorrect. The correct probability should be less than 1 since events A and B are not mutually exclusive.
To calculate the correct probability, we need to determine the probability of both events occurring together, which is the probability of rolling an even number less than 4. In this case, the probability of event A and event B occurring simultaneously is P(A and B) = 1/6 (since only the number 2 satisfies both conditions).
Using the formula P(A or B) = P(A) + P(B) - P(A and B), we have P(A or B) = 1/2 + 1/2 - 1/6 = 2/3.
Therefore, the probability that either event A or event B will occur is 2/3, not simply the sum of the individual probabilities.
