A balance sheet is a financial statement that presents a company's financial position at a specific point in time. It shows the company's assets, liabilities, and equity.

What are the steps for the balance sheet?

Here are the steps to compute a balance sheet:

List all the assets: Assets are what the company owns, and they can be classified as current assets or long-term assets. Current assets include cash, accounts receivable, inventory, and prepaid expenses. Long-term assets include property, plant, and equipment, investments, and intangible assets.

Calculate the total value of assets: Add up the value of all the assets listed in step 1.

List all the liabilities: Liabilities are what the company owes to others and can be classified as current liabilities or long-term liabilities. Current liabilities include accounts payable, short-term loans, and accrued expenses. Long-term liabilities include long-term loans and bonds.

Calculate the total value of liabilities: Add up the value of all the liabilities listed in step 3.

Calculate equity: Equity is the difference between the assets and liabilities. It can be calculated as Total Assets minus Total Liabilities.

List equity: Write down the equity value calculated in step 5.

Add up the total liabilities and equity: This should be equal to the total assets calculated in step 2.

The balance sheet formula is:

Assets = Liabilities + Equity

By following the above steps, you can compute a balance sheet for a company. It is important to note that the balance sheet is a snapshot of the company's financial position at a specific point in time and should be updated regularly.

Answers

The polynomial equation with the roots is P(x) = x^2 - 15x + 56

How to determine the polynomial equation

From the question, we have the following parameters that can be used in our computation:

Roots: x = 8 and x = 7

Using the above as a guide, we have the following:

The equation can be represented as

P(x) = (x - root)

Substitute the known values in the above equation, so, we have the following representation

P(x) = (x - 8)(x - 7)

Evaluate the product

P(x) = x^2 - 8x - 7x + 56

This gives

P(x) = x^2 - 15x + 56

The area of a rectangular room is 750 square feet. The width of the room is 5 feet less than the length of the room. Which equations can be used to solve for y, the length of the room? Select three options. y(y + 5) = 750 y2 – 5y = 750 750 – y(y – 5) = 0 y(y – 5) + 750 = 0 (y + 25)(y – 30) = 0 Mark this and return

Answers

Answer:

Listed below.

Step-by-step explanation:

(Let y be the length of the room and x be the width of the room.)

Because the width of the room is 5 feet less than the length of the room, we have:

x = y - 5.

The area of the room can be solved by multiplying its length and width, so we have x × y or xy = 750.

Substituting x for y - 5 into this equation:

y (y - 5) = 750.

If we expand the left side of the equation, we get:

[tex]y^{2}[/tex] - 5y = 750

Subtracting 750 from both sides, we get:

[tex]y^{2}[/tex] - 5y - 750 = 0

The equation [tex]y^{2}[/tex] - 5y - 750 = 0 can be factored into:

(y + 25) (y - 30) = 0

Therefore, 3 equations you can use are:

y (y - 5) = 750[tex]y^{2}[/tex] - 5y - 750 = 0(y + 25) (y - 30) = 0

Answers

The subtraction of 3045 and 2572 by the column method has the result given as follows:

473.

How to obtain the subtraction using the column method?

When we subtract two amounts by the column method, we subtract digit by digit separately, hence:

3045

-2572

5 > 2, hence:

5 - 2 = 3.

4 is less than 7, and 0 is also less than 5, hence we must borrow from the last column, where 2 - 2 will be of zero, hence:

14 - 7 = 7.9 - 5 = 4. -> one was borrowed to the 4 - 7 subtraction.

what radian measure is equal to 315?

Answers

The radian measure for 315° is (7/4)π radians.

What exactly is a radian measure?

Radian measure is a unit of measurement for angles, where one radian is defined as the central angle subtended by an arc of a circle with a length equal to the radius of the circle. Therefore, to convert degrees to radians, we need to multiply the degree measure by pi/180.

Now,

To convert 315 degrees to radians, we can use the formula:

radians = degrees x π/180

So, we have:

radians = 315 x π/180

Simplifying this expression, we get:

radians = (7/4) x π

Therefore,

             315 degrees is equal to (7/4) π radians.

Answers

To find the volume of the region under the graph of f(x,y) = 3x + y + 1 and above the region y^2 ≤ x, 0 ≤ x ≤ 9, we need to integrate f(x,y) over the given region.

The region is bounded by the curves y = sqrt(x) and y = -sqrt(x), and the lines x = 0 and x = 9. So, we can set up the double integral as follows:

∫(from 0 to 9)∫(from -sqrt(x) to sqrt(x)) (3x + y + 1) dy dx

Evaluating the inner integral with respect to y, we get:

∫(from 0 to 9) [ (3x + y + 1)y ] (from -sqrt(x) to sqrt(x)) dx
= ∫(from 0 to 9) [ (3x + sqrt(x) + 1)sqrt(x) - (3x - sqrt(x) + 1)sqrt(x) ] dx
= ∫(from 0 to 9) [ 2sqrt(x) + 1 ] dx
= [ (4/3)x^(3/2) + x ] (from 0 to 9)
= 108 + 9sqrt(3)

Therefore, the volume of the region under the graph of f(x,y) = 3x + y + 1 and above the region y^2 ≤ x, 0 ≤ x ≤ 9 is 108 + 9sqrt(3) cubic units.

Step-by-step explanation:

You want the minimum value of f(x) = x² +6x +4.

Line of symmetry

The line of symmetry of a quadratic function f(x) = ax² +bx +c is given by ...

  x = -b/(2a)

The line of symmetry passes through the extreme point. When a > 0, that extreme point is the minimum.

Here, we have a=1, b=6, so the line of symmetry is ...

  x = -6/(2·1) = -3

Extreme

The extreme point (minimum) is ...

  f(-3) = (-3)² +6(-3) +4 = (-3 +6)(-3) +4 = -9 +4

  f(-3) = -5

The minimum value of f(x) is -5.

Answers

The answer of the given question based on the constant of proportionality the answer is  constant of proportionality equal to 1.

What is Slope?

Slope is  measure of  steepness of a line. It describes how much  vertical coordinate (y) changes for given change in  horizontal coordinate (x). In other words, it is  rate at which  line rises or falls as you move horizontally along it

To find the constant of proportionality between y and x, we need to calculate the slope of this line.

We can choose any two points on the line and use them to calculate the slope. Let's choose the points (2, 2) and (8, 8), which are the first and last points on the line. The slope of the line passing through these points is:

slope = (change in y)/(change in x) = (8 - 2)/(8 - 2) = 1

This means that for every increase of 1 in the x-coordinate, there is a corresponding increase of 1 in the y-coordinate. Therefore, the constant of proportionality between y and x is 1. We can write this as:

y = x

This means that y is directly proportional to x with a constant of proportionality equal to 1.

Challenger Deep in the Pacific Ocean is the deepest point in Earth's oceans. It is 38 797 ft. below sea level. What is this depth to the nearest fathom? Is this depth greater than or less than 7 mi.? Explain.​

Answers

Answer:

Therefore, the depth of Challenger Deep to the nearest fathom is 6,466 fathoms, and it is greater than 7 miles.

Step-by-step explanation:

One fathom is equal to 6 feet. To convert 38,797 ft. to fathoms, we divide by 6:

38,797 ft. / 6 = 6,466.17 fathoms

Rounding this to the nearest fathom gives us 6,466 fathoms.

One mile is equal to 5,280 feet. Seven miles would be:

7 mi. x 5,280 ft/mi = 36,960 ft.

Since 38,797 ft. is greater than 36,960 ft., we can conclude that Challenger Deep's depth is greater than 7 miles.

Therefore, the depth of Challenger Deep to the nearest fathom is 6,466 fathoms, and it is greater than 7 miles.

what is probability ?

The measurement and study of random events are the focus of the mathematic branch known as probability. It is a means to express how likely an event or series of events are to occur. Probability is stated as a number between 0 and 1, where 0 denotes the impossibility of an event and 1 denotes its certainty. An occurrence that has a probability of 0.5 (or 50%) is equally likely to occur or not. In a variety of disciplines, including statistics, economics, engineering, and science, probability is used to evaluate and forecast the possibility of specific events in light of the information and presumptions at hand.

given

The formula for the union of two events must be used to determine the likelihood that a visitor will go to either the Magic Kingdom or Epcot Center:

P(A or B) equals P(A) + P(B) - P (A and B)

P(A) represents the likelihood that event A will occur, P(B) represents the likelihood that event B will occur, and P(A and B) represents the likelihood that both events will occur at the same time.

Let's describe event A in this scenario as a trip to the Magic Kingdom, and event B as a trip to the Epcot Center. We are aware of:

P(A) = 0.60 (the Magic Kingdom is visited by 60% of tourists)

P(B) = 0.50 (50 percent of tourists go to the Epcot Center)

P(A and B) = 0.25 (25% of tourists go to both places).

The result of the formula is:

P(A or B) is equal to P(A) + P(B) - P(A and B), which is 0.60 + 0.50 - 0.25 = 0.85.

As a result, 0.85 or 85% of vacationers are likely to visit either the Magic Kingdom or Epcot Center.

Answers

Using the system of equations, we found that the amount to be invested in fund A is $180,000 and in fund B is $320,000.

What is meant by an equation?

A mathematical equation is a formula that uses the equals sign to represent the equality of two expressions. Two expressions are combined in an equation using an equal symbol ("="). The "left-hand side" and "right-hand side" of the equation are the two expressions on either side of the equals sign. Typically, we consider an equation's right side to be zero. As we can balance this by deducting the right-side expression from both sides' expressions, this won't reduce the generality.

The amount in the IRA account = $500,000

Let the amount invested in fund A be x and fund B be y.

x + y = 500,000

The amount received annually for fund A = 0.052x

The amount received annually for fund B = 0.077y

This amount is given as:

0.052x + 0.077y = 34,000

Now we have a system of equations.

x + y = 500,000

0.052x + 0.077y = 34,000

Multiply the first equation by 0.052.

0.052x + 0.052y = 26,000

0.052x + 0.077y = 34,000

Subtracting,

-0.025y = -8000

y = 320,000

Then, x = 500,000 - y = 500,000 - 320,000 = 180,000

Therefore using the system of equations, we found that the amount to be invested in fund A is $180,000 and in fund B is $320,000.

What percent of the company has advanced degrees?

Answers

The company's advanced degree holders make up 18% of the workforce.

A percentage is what?

A percentage, which is denoted by the number 100, is a proportion, fraction, or piece of a whole. The Roman phrase per centum, which meaning "by the 100" or "per one hundred," is where the term "percent" originates. A numerical value and the percentage symbol (%) can be used to express percentages.

Part A:

The following expression sums up the amount of company employees with advanced degrees:

0.40c(0.15) + 0.60c(0.20)

Explanation: First, we multiply the overall amount of workers (c) by the proportions of male and female employees, which are, respectively, 40% and 60%. The number of male workers (0.40c) is then multiplied by the percentage of men who have advanced degrees (15%), and the number for female employees (0.60c) is multiplied by the percentage of women who have advanced degrees (20%). In order to calculate the overall number of workers with advanced degrees, we must add these two numbers.

If we condense this phrase, we get:

0.06c + 0.12c = 0.18c

Part B:

The number of staff members with advanced degrees must be divided by the total amount of employees, and the result must be multiplied by 100% to determine the percentage of the business that holds advanced degrees:

(0.18c/c) × 100% = 18%

Therefore, 18% of the company has advanced degrees.

A hypothesis is an educated guess or tentative explanation for a phenomenon or observation that can be tested through further investigation and experimentation. It is a proposed explanation or prediction for an event or set of events that is based on limited evidence or observations, and which serves as the starting point for scientific inquiry.

According to question:

Based on the given information, Megan cleared 5'6" for 80% of her jumps. To create a hypothesis for the probability of future jumps cleared at 5'6", we need to make an educated guess based on this data.

Option A, stating that Megan will clear 5'6" for 100% of her jumps, is too optimistic and doesn't take into account the possibility of error or difficulty in jumping.

Option B, stating that Megan will clear 5'4" for 100% of her jumps, is not relevant to the given information about Megan's performance at 5'6".

Option D, stating that Megan will clear 5'8" on 80% or more of her jumps, is also not supported by the given information and is too high of a goal for Megan to realistically achieve.

Therefore, the best hypothesis based on the given information is Option C: Megan will clear 5'6" on 80% or more of her jumps. This hypothesis is supported by the fact that Megan has already achieved this level of performance in the past, and it allows for the possibility of some variability or error in future jumps.

1. Use the pythagorean identity
Find cotθ if cosθ = 1/7 and the value exists in the first quadrant.

I have a calculus exam tomorrow and have no idea how to solve this equation, please provide a detailed explanation. I'm slow.

Answers

Answer:

Let's first recall the Pythagorean identity:

sin²θ + cos²θ = 1

We can use this identity to find the value of sinθ, given that cosθ = 1/7 and θ is in the first quadrant. Since θ is in the first quadrant, both sinθ and cosθ are positive.

cosθ = 1/7

cos²θ = (1/7)² = 1/49

sin²θ + cos²θ = 1

sin²θ + 1/49 = 1

sin²θ = 1 - 1/49 = 48/49

sinθ = √(48/49) = (4/7)√3

Now we can use the definition of cotangent to find cotθ:

cotθ = cosθ/sinθ

Substituting the values we found for cosθ and sinθ, we get:

cotθ = (1/7)/[(4/7)√3] = √3/4

Therefore, cotθ = √3/4 when cosθ = 1/7 and θ is in the first quadrant.

Answers

Answer:

So the answer is 24.2

Step-by-step explanation:

Good luck to you!

according to the model, Marie's lowest time after 14 weeks of training will be 24.2 seconds.

What is a linear equation?

Based on the given linear model, we know that Marie's best 200 meter time (y) is a function of the number of weeks of training (x), and can be calculated using the equation:

y = -0.4x + 29.8

To find Marie's lowest time after 14 weeks, we simply need to substitute x = 14 into the equation and solve for y:

y = -0.4(14) + 29.8

y = -5.6 + 29.8

y = 24.2

Therefore, according to the model, Marie's lowest time after 14 weeks of training will be 24.2 seconds.

Which of the following statements is MOST LIKELY TRUE?


A-The lower half of Sample A's data is closer to the value 5 than the lower half of Sample B's data.

B-Both of the data sets range from 1 to 10 on the number line.

C-The upper half of Sample A's data is closer to the value 10 than the upper half of Sample B's data.

D-The data in Sample B is clustered around the center where Sample A is more spread out

Answers

The statement that is most likely true is: "The data in Sample B is clustered around the center where Sample A is more spread out."

What is data set?

A dataset is a collection of information, often represented in a tabular form, that contains one or more variables or pieces of data for a particular set of individuals or observations. Each individual or observation in the dataset is typically represented by a row in the table, while the variables are represented by columns. Datasets can be used to study a wide variety of phenomena, from social and economic trends to scientific experiments and medical studies. They can be collected through a variety of methods, including surveys, experiments, observations, and automated data collection systems, and can be analyzed using statistical methods to gain insights into the underlying patterns and relationships in the data.

Here,

This is because Sample A has a larger range than Sample B, indicating that the data points in Sample A are more spread out across the number line. Additionally, the median for both samples is the same (5), but the mean for Sample A is higher than the mean for Sample B, which could suggest that there are some larger values pulling the mean upward in Sample A. Taken together, these characteristics suggest that Sample A has more variability in its data points, while Sample B is more clustered around the center.

21. Brian took out a 48-month (4 years) loan for $1,800 at
an annual interest rate of 12%. Andy took out a
2-year loan for $4,200 at an annual interest rate of
10%. Who paid more in interest and how much more
did he pay?

A. Andy paid $34 more in interest.
B. Brian paid $34 more in interest.
C. Andy paid $24 more in interest.
D .Brian paid $24 more in interest.

Answers

Answer:

To find the total interest paid by Brian, we can use the simple interest formula:

I = P * r * t

where I is the interest, P is the principal (the amount borrowed), r is the annual interest rate as a decimal, and t is the time period in years.

For Brian's loan, we have:

I = 1800 * 0.12 * 4 = $864

So Brian paid a total of $864 in interest over the 4-year term.

For Andy's loan, we can use the same formula:

I = 4200 * 0.10 * 2 = $840

So Andy paid a total of $840 in interest over the 2-year term.

To find the difference in interest paid, we subtract the smaller amount from the larger amount:

864 - 840 = $24

Therefore, Brian paid $24 more in interest than Andy. The answer is option D.

Answer: the answer is C. Brian paid $24 more in interest than Andy.

Step-by-step explanation: To find out how much interest each person paid, we can use the formula:

Interest = Principal x Rate x Time

where Principal is the amount borrowed, Rate is the annual interest rate (as a decimal), and Time is the length of the loan (in years).

For Brian's loan:

Principal = $1,800

Rate = 0.12

Time = 4 years

Interest = $1,800 x 0.12 x 4 = $864

For Andy's loan:

Principal = $4,200

Rate = 0.10

Time = 2 years

Interest = $4,200 x 0.10 x 2 = $840

So Andy paid $840 in interest, while Brian paid $864 in interest. To find out how much more Brian paid than Andy, we can subtract:

$864 - $840 = $24
