The company's debt to equity ratio will decrease as a result of receiving cash of $1,000,000 from issuing common stock at par value.

The debt to equity ratio is a financial ratio that measures the proportion of a company's debt to its equity, indicating the company's leverage or reliance on debt financing. It is calculated by dividing total debt by total equity.

In this scenario, the company received cash of $1,000,000 from issuing common stock at par value. Since this cash infusion increases the equity of the company, the denominator in the debt to equity ratio increases.

However, since there is no mention of any change in the company's debt, the numerator of the debt to equity ratio remains the same.

As a result, when the equity increases and the debt remains the same, the ratio of debt to equity decreases. Therefore, the debt to equity ratio will decrease as a result of the transaction.

The intensity will be 304R, the correct option is d. 304R

An attribute of being intense or the quantifiable amount of a property, such as force, brightness, or a magnetic field, are both considered to be intensities.

The intensity of a source follows the inverse square law, which states that the intensity is inversely proportional to the square of the distance from the source.

Let's denote the initial distance as d1 (15 inches) and the initial intensity as I1 (10R). Let d2 (45 inches) be the new distance, and we need to find the new intensity, denoted as I2.

According to the inverse square law:

I1 / I2 = (d2 / d1)²

Plugging in the values:

10R / I2 = (45 inches / 15 inches)²

Simplifying:

10R / I2 = 3²

10R / I2 = 9

Now, solve for I2:

I2 = 10R / 9

So, the intensity at 45 inches (I2) will be 10R divided by 9.

Therefore, the answer is:

d. 304R

The coterminal angles within the range 0° ≤ θ < 360° are -423°, -23° and 337°.

Since -783° is negative, it lies in the clockwise direction means it falls in the fourth quadrant.

The reference angle is 423°.

The coterminal angle, quadrant and reference angle for the rotation of -783°, we can use the following calculations:

Coterminal Angle:

To find a coterminal angle, we need to add or subtract multiples of 360° to the given angle until we obtain an angle within the range of 0° to 360°.

-783° + 360° = -423°

-783° + 2 × 360° = -23°

-783° + 3 × 360° = 337°

The coterminal angles within the range 0° ≤ θ < 360° are -423°, -23° and 337°.

Quadrant:

To determine the quadrant in which the angle lies, we can observe the sign of the angle:

Reference Angle:

The reference angle is the acute angle between the terminal side of the angle and the x-axis.

To find the reference angle, we can calculate the positive equivalent of the angle within one revolution (360°).

The positive equivalent of -783° can be found by adding 360° repeatedly until we obtain a positive angle:

-783° + 360° = -423° (already found as a coterminal angle)

The positive equivalent of -783° is -423°.

The reference angle is the absolute value of the positive equivalent:

Reference angle = |-423°| = 423°

The coterminal angles are -423°, -23°, and 337°.

The angle -783° falls in the fourth quadrant.

Lauren's accounting profit can be calculated by subtracting her total expenses (rent, labor costs, and overhead expenses) from her total revenue.

To determine Lauren's accounting profit, we need to subtract her total expenses from her total revenue. Her total revenue for the year was $145,000. Her total expenses include rent ($12,000), labor costs ($65,000), and overhead expenses ($15,000).

To calculate her accounting profit, we subtract the total expenses from the total revenue:

Accounting Profit = Total Revenue - Total Expenses

Accounting Profit = $145,000 - ($12,000 + $65,000 + $15,000)

Accounting Profit = $145,000 - $92,000

Accounting Profit = $53,000

Therefore, Lauren's accounting profit for the year is $53,000. This represents the amount of interests left after deducting all the expenses from the total revenue. It is important to note that accounting profit does not take into account other factors such as opportunity costs or non-cash expenses, but it provides a basic measure of the profitability of the business based on the given information.

On December 11, 2019, Fred gave a $20,000, 60-day, 9% note to Barnie in payment of an account. On December 31, 2019, Barnie should record $300 as the interest on December 31, 2019.

To calculate the interest on the note, we need to determine the interest for the 60-day period using a commercial year, which typically consists of 360 days.

The interest can be calculated using the formula:

Interest = Principal × Rate × Time

Principal = $20,000

Rate = 9% or 0.09

Time = 60 days / 360 days (commercial year)

Let's calculate the interest:

Time = 60 days / 360 days

        = 1/6

Interest = $20,000 × 0.09 × (1/6)

             = $20,000 × 0.09 × 1/6

             = $20,000 × 0.015

The probability that the daily water level in the lake will be at least 90 feet is 0.37. The correct option is (D) 0.37.

To find the probability that the daily water level in the lake will be at least 90 feet, we can use the normal distribution. Given that the mean water level is 84.07 feet, we need to calculate the probability that a random daily water level is greater than or equal to 90 feet.

First, we need to find the z-score corresponding to 90 feet. The z-score formula is:

z = (x - μ) / σ

Where x is the value we want to find the probability for, μ is the mean, and σ is the standard deviation.

In this case, x = 90 feet, μ = 84.07 feet, and the standard deviation is not provided. However, since the problem states that the daily water level is approximately normally distributed, we can assume a standard deviation of 100 feet (as stated in the problem).

Calculating the z-score:

z = (90 - 84.07) / 100 = 0.0593

To find the probability corresponding to this z-score, we can use a standard normal distribution table or a calculator. Looking up the closest value to 0.0593 in the table, we find that it is approximately 0.5297.

However, we are interested in the probability of the water level being at least 90 feet, so we need to subtract this probability from 1:

P(at least 90 feet) = 1 - 0.5297 ≈ 0.4703

Therefore, the option closest to this probability is (D) 0.37.

When workers identified with the interests of capitalists, Marx called it false class consciousness.

False class consciousness is a concept in Marxist theory that describes a situation where members of the working class adopt the beliefs, values, and interests of the capitalist class instead of recognizing and pursuing their own class interests. Marx argued that the capitalist system inherently creates conditions that obscure the true nature of class relations and exploitation.

According to Marx, the capitalist class holds economic and political power and benefits from the labor of the working class. However, the capitalist class uses various means, such as ideology and cultural influences, to shape the consciousness of the working class. This results in the workers aligning themselves with the interests of the capitalists, often believing that their own success is tied to the success of the capitalist system.

Marx believed that false class consciousness hindered the potential for revolutionary class struggle and collective action by the working class. He argued that by accepting the dominant capitalist ideology, workers remained unaware of their own exploitation and continued to support a system that perpetuated their subjugation.

Marx's concept of false class consciousness emphasized the importance of class awareness and the need for workers to develop a true class consciousness, recognizing their common interests and working towards collective action to challenge and transform the capitalist system.

In summary, false class consciousness refers to the situation where workers adopt the beliefs and interests of the capitalist class, failing to recognize their own exploitation and working against their own class interests. It is a concept that highlights the ideological influence of the capitalist class in shaping the consciousness of the working class.

To determine if the weight and balance of an airplane are within limits, calculations need to be performed. These calculations consider the weights of various components and their respective arm distances from the reference datum.

By comparing the calculated center of gravity (CG) with the allowable CG range, it can be determined if the CG and weight of the airplane are within limits. Weight and balance calculations are crucial for ensuring the safety and performance of an aircraft. The weight and balance system involves determining the weights of different components, such as the airframe, engines, fuel, passengers, cargo, and other equipment. Each component's weight is multiplied by its arm distance from the reference datum, which is a fixed point on the aircraft.

The arm is the horizontal distance between the reference datum and the center of gravity of a particular component. The center of gravity is the point at which the aircraft would balance if it were suspended. By summing the moments (weight multiplied by arm) of all components and dividing it by the total weight, the CG can be calculated.

To determine if the CG and weight of the airplane are within limits, the calculated CG is compared to the allowable CG range specified by the aircraft manufacturer. The allowable CG range defines the limits within which the aircraft must operate to ensure stability and controllability. If the calculated CG falls within this range, the weight and balance are considered within limits. However, if the calculated CG exceeds the allowable range, it indicates an imbalance and corrective measures, such as redistributing weight or adjusting the load, are necessary to bring the CG within acceptable limits.

In conclusion, weight and balance calculations involve determining the weights and arm distances of various components in an aircraft. By calculating the CG and comparing it to the allowable CG range, it can be determined if the weight and CG of the airplane are within limits. Ensuring proper weight distribution and CG positioning is vital for maintaining stability and controllability during flight.

To determine the weight of the stock fund in the minimum variance portfolio, we need to consider the standard deviations of both the stock fund and the bond fund, as well as the correlation between the two funds.

The minimum variance portfolio is a portfolio allocation that minimizes the overall portfolio's volatility or risk. The weight of each asset in the portfolio is determined based on the standard deviations of the assets and their correlation.

The formula to calculate the weight of an asset in the minimum variance portfolio is:

Weight of asset = (Standard deviation of other asset / Standard deviation of asset + Standard deviation of other asset) * (1 - Correlation)

In this case, the stock fund has a standard deviation of 16% and the bond fund has a standard deviation of 4%. The correlation between the two funds is 0.11.

To calculate the weight of the stock fund, we plug in the values into the formula:

Weight of stock fund = (4% / (16% + 4%)) * (1 - 0.11)

= (0.04 / 0.20) * (0.89)

≈ 0.178

The next two steps for the students to analyze their DNA by Southern blot are gel electrophoresis and DNA transfer to a membrane.

After purifying the DNA and cutting it with the endonuclease, the next step is gel electrophoresis. Gel electrophoresis is a technique used to separate DNA fragments based on their size. The DNA samples are loaded onto an agarose gel and an electric field is applied. The DNA fragments migrate through the gel based on their size, with smaller fragments moving faster and traveling farther than larger fragments.

Following gel electrophoresis, the next step is DNA transfer to a membrane. This step involves transferring the separated DNA fragments from the gel onto a solid support membrane, typically made of nitrocellulose or nylon. This transfer is achieved through a process called capillary or electroblotting, where the DNA is transferred from the gel to the membrane by applying an electric current or using a blotting apparatus.

Alex can make a total of 180 different sandwiches by choosing one kind of meat from 10 options and two kinds of cheese from 9 options.

To determine the number of different sandwiches Alex can make, we need to consider the combinations of meat and cheese. Since Alex can choose one kind of meat from 10 options, there are 10 choices for the meat component of the sandwich. For the cheese component, Alex can choose two kinds of cheese from 9 options.

To calculate the total number of combinations, we can use the formula for combinations without repetition. The formula is nCr = n! / (r!(n-r)!), where n is the total number of options and r is the number of choices. In this case, n is 9 (number of cheese options) and r is 2 (number of cheese choices).

The phosphorylation of a protein kinase upon downstream signaling by phosphorylated insulin receptor substrate-1 is responsible for promoting cell division and growth.

nsulin receptor substrate-1 (IRS-1) is a protein involved in insulin signaling pathways. When insulin binds to its receptor on the cell surface, it initiates a cascade of intracellular events. One of the key steps in this signaling pathway is the phosphorylation of IRS-1. Upon phosphorylation of IRS-1, it serves as a docking protein for various downstream signaling molecules, including protein kinases. One of the protein kinases that can be activated through this interaction is responsible for promoting cell division and growth.

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.
