If the flowing water is under a gauge pressure of 240 psi, the longitudinal stress developed in the wall of the pipe would be approximately 866,400 pounds per square foot (psf).

Axial stress is another name for longitudinal stress. Axial stress, also referred to as longitudinal stress, is a sort of stress that runs along the object's length, or along the material's longitudinal axis.

To determine the longitudinal stress developed in the wall of the pipe, we need to know the diameter of the pipe and the material it is made of. The longitudinal stress can be calculated using the formula:

Longitudinal Stress = (Pressure × Diameter) / (2 × Wall Thickness)

Let's assume that we have a pipe with a diameter of 10 inches (0.8333 feet) and a wall thickness of 0.2 inches.

First, we need to convert the gauge pressure from psi to pounds per square foot (psf):

240 psi = 240 * 144 psf = 34,560 psf

Substituting the values into the formula:

Longitudinal Stress = (34,560 psf × 0.8333 ft) / (2 × 0.2 inches)

Converting the wall thickness to feet:

0.2 inches = 0.2/12 ft = 0.0167 ft

Calculating the longitudinal stress:

Longitudinal Stress = (34,560 psf × 0.8333 ft) / (2 × 0.0167 ft)

Longitudinal Stress ≈ 866,400 psf

Therefore, if the flowing water is under a gauge pressure of 240 psi, the longitudinal stress developed in the wall of the pipe would be approximately 866,400 pounds per square foot (psf).

Answer:

No, she can't

Step-by-step explanation:

The equation to solve the problem is the following:

y=0.5x+2.25

where x is the # of miles and y is the amount charged based on the flat rate and the additional $0.50 per mile (x).

y should be less than or equal to 10 since that's the maximum Annie can pay.

Annie would have to spend $11.25 to travel 18 miles, but she can spend at most $10 ⇒ she can't travel 18 miles.

Hyponatremia is associated with overhydration and dehydration. Hyponatremia is a condition characterized by low levels of sodium in the blood.

While options a and c (insufficient intake of dietary calcium and excessive intake of dietary sodium) may have an impact on overall health, they are not directly linked to hyponatremia. The correct associations for hyponatremia are overhydration (b) and dehydration (d).

Overhydration, or water intoxication, occurs when the body takes in more water than it can excrete. This dilutes the concentration of sodium in the blood, leading to hyponatremia. Overhydration can be caused by excessive fluid intake, particularly in cases of endurance sports or drinking large amounts of water without proper electrolyte balance.

On the other hand, dehydration can also contribute to hyponatremia. When the body loses more water than it takes in, the sodium levels in the blood become relatively higher, resulting in diluted sodium concentration. This can occur due to excessive sweating, vomiting, diarrhea, or certain medical conditions.

In both cases, the balance of fluids and electrolytes in the body is disrupted, leading to low sodium levels and the development of hyponatremia. It is important to maintain a healthy fluid intake, ensuring a proper balance of water and electrolytes, to prevent these conditions and maintain overall well-being.

American jurists (fill in the names) defined law as predictions of how a court will decide specific legal questions, based on a functional perspective.

American jurists Oliver Wendell Holmes Jr. and Benjamin Cardozo are known for their functionalist approach to defining law. They viewed law not merely as a set of abstract principles or rules, but as a prediction of how courts will decide specific legal questions in practice. According to their perspective, the law should be seen as a dynamic and evolving system that adapts to societal changes and reflects the judgments and decisions of the judiciary. By emphasizing the functional aspect of law, Holmes and Cardozo recognized the importance of considering how legal principles are actually applied and interpreted in real-world scenarios. Their approach acknowledges that the interpretation and application of law by judges can vary and evolve over time, depending on factors such as legal precedent, social context, and the specific facts of the cases before them.

When Q > K, the amount of products must decrease and the amount of reactants must increase for equilibrium to be established. Therefore, the reaction will proceed in the reverse direction to establish equilibrium.

When discussing chemical reactions and equilibrium, the reaction quotient (Q) and equilibrium constant (K) play important roles.

The reaction quotient is calculated in the same way as the equilibrium constant, but it can be evaluated at any point during the reaction, not just at equilibrium.

If the reaction quotient, Q, is greater than the equilibrium constant, K (Q > K), it indicates that the system has an excess of products compared to what is required at equilibrium.

To establish equilibrium, the reaction needs to shift in the reverse direction to reduce the concentration of products and increase the concentration of reactants.

This shift occurs because the system seeks to minimize the imbalance caused by the excess of products.

By proceeding in the reverse direction, the reaction consumes some of the excess products and forms more reactants.

As reactants are consumed, their concentration increases, bringing the system closer to equilibrium. The reaction will continue to proceed in the reverse direction until Q becomes equal to K, indicating that the system has reached equilibrium.

In summary, when Q > K, the reaction will proceed toward the reverse direction to establish equilibrium by reducing the concentration of products and increasing the concentration of reactants.

After 1 hour, the alcohol percentage of the beer in the tank will be approximately 5.62%. Initially, the tank contains 100 gallons of beer with 5% alcohol, resulting in 5 gallons of alcohol. The alcohol percentage is approximately 3.2/40 * 100 = 8%.

For every minute, 1 gallon of beer with 7% alcohol is pumped in, contributing 0.07 gallons of alcohol. At the same time, 2 gallons of beer are drained from the tank, resulting in a loss of 0.1 gallons of alcohol. After 60 minutes, a total of 60 gallons of 7% alcohol beer is pumped in, adding 4.2 gallons of alcohol. Meanwhile, 120 gallons of beer are drained out, removing 6 gallons of alcohol. Combining the initial alcohol content with the inflow and outflow, we find that the tank contains 100 + 60 - 120 = 40 gallons of beer after 1 hour, with 5 + 4.2 - 6 = 3.2 gallons of alcohol. Thus, the alcohol percentage is approximately 3.2/40 * 100 = 8%.

In conclusion, after 1 hour, the beer in the tank will have an alcohol percentage of approximately 5.62%. The calculation takes into account the initial alcohol content, the inflow rate of beer with higher alcohol percentage, and the outflow rate of the mixed beer. By considering the amounts of alcohol gained and lost during the hour, we determine that the tank will contain 40 gallons of beer with 3.2 gallons of alcohol. Dividing the alcohol content by the total volume of beer and multiplying by 100 yields the final alcohol percentage.

A person living in a Midwestern city who drinks two liters of tap water containing 150 mg Ca/L would receive approximately 20% of their recommended daily requirement (RDA) of calcium.

The recommended daily requirement of calcium is 1000 mg, and the tap water in the Midwestern city contains approximately 150 mg of calcium per liter. If a person drinks two liters of water in one day, they would consume a total of 300 mg of calcium (150 mg/L * 2 L). To determine the percentage of their RDA, we can divide the amount of calcium obtained from the water (300 mg) by the recommended daily requirement (1000 mg) and multiply by 100.

Mathematically, it would be (300 mg / 1000 mg) * 100 = 0.3 * 100 = 30%. Therefore, a person living in the Midwestern city who drinks two liters of tap water would receive approximately 30% of their RDA of calcium. This means that drinking tap water alone would not fulfill their entire daily calcium requirement, and additional sources of calcium-rich foods or supplements may be necessary to meet their RDA.

We need an approximate sample size of n = 122 to estimate the population means the age of the incoming fall term transfer students, with a population standard deviation of 5.4, a margin of error of 2.3, and a confidence level of 99%. Therefore, the answer is 122.

The formula for calculating the sample size, given the population standard deviation, the desired level of confidence, and the margin of error, is as follows:

n = (zα/2)² * σ² / E²

Where, α is the significance level, zα/2 is the z-score at the α/2 percentile of the standard normal distribution, σ is the population standard deviation, E is the margin of error

To calculate the sample size required to estimate the population means age of the incoming fall term transfer students, with a population standard deviation of 5.4, a margin of error of 2.3, and a confidence level of 99%, we can substitute these values in the formula:n = (zα/2)² x σ² / E²

Where α = 0.01 (since we want a 99% confidence level, we need to subtract 1 from 100 and convert it to a decimal)

E = 2.3σ = 5.4

Using a z-table or a calculator, we can find the z-score at the 0.005 level of the standard normal distribution. The z-score is approximately 2.576.

n = (2.576)² * (5.4)² / (2.3)²

The perimeter of the fountain is approximately 28.3 times the radius (r).

To find the perimeter of the fountain, we need to calculate the combined lengths of the two semicircles and the quarter circle.

Let's assume the radius of the semicircles is "r" and the radius of the quarter circle is "r/2" (since the quarter circle is half the size of the semicircle).

The perimeter of a semicircle is given by half the circumference of a full circle:

Perimeter of a semicircle = (1/2) × 2πr = πr

The perimeter of the quarter circle is given by one-fourth the circumference of a full circle:

Perimeter of a quarter circle = (1/4) × 2π(r/2) = (1/4) × πr = πr/4

Since we have two semicircles and one quarter circle, the total perimeter of the fountain is:

Total Perimeter = 2 × (Perimeter of a semicircle) + (Perimeter of a quarter circle)

Total Perimeter = 2πr + πr/4

Total Perimeter = (8πr + πr)/4

Total Perimeter = 9πr/4

Now, we need to round the answer to the nearest tenth. The value of π (pi) is approximately 3.14159. Therefore, we can substitute this value to get an approximate answer:

Total Perimeter ≈ 9 × 3.14159 × r/4

Total Perimeter ≈ 28.27431 × r

The one-way distance between the starting point and Philadelphia is approximately 800.8 miles. The round trip distance would be 2D, which is approximately 2 * 800.8. Option D

To determine the total distance the plane flies round trip, we can use the concept of average speed. The average speed is calculated by dividing the total distance traveled by the total time taken.

Let's assume the one-way distance between the starting point and Philadelphia is D miles. Therefore, the round trip distance would be 2D.

When flying to Philadelphia at a speed of 220 miles per hour, the time taken is D/220 hours.

On the return trip, the plane has a tailwind and flies at 280 miles per hour. The time taken to return is D/280 hours.

The total flying time is given as 6.5 hours, so we can set up the equation:

D/220 + D/280 = 6.5

To solve this equation, we can find a common denominator and simplify:

280D + 220D = 6.5 * 220 * 280 500D = 6.5 * 220 * 280 D = (6.5 * 220 * 280) / 500 D ≈ 800.8. Option D is correct.

It seems that you have provided a sequence represented by the function c(n). The function is given as:

c(n) = (-9/2) * (-4/3)^(n-1)

This function represents a geometric sequence, where each term is obtained by multiplying the previous term by a constant ratio of -4/3.

The first term of the sequence (corresponding to n = 1) can be found by substituting n = 1 into the given function:

c(1) = (-9/2) * (-4/3)^(1-1)

= (-9/2) * (-4/3)^0

= (-9/2) * 1

= -9/2

Therefore, the first term of the sequence is -9/2.

To find subsequent terms, you can substitute different values of n into the function and evaluate the expression. Each term will be the previous term multiplied by -4/3.

For example, the second term (corresponding to n = 2) is:

c(2) = (-9/2) * (-4/3)^(2-1)

= (-9/2) * (-4/3)

= 18/2 * 4/3

= 36/6

= 6

So, the second term is 6.

Similarly, you can calculate other terms of the sequence by substituting different values of n into the function.
