The percentage of completion method is a widely used accounting method to recognize revenue and expenses over the life of a long-term project or contract.

It is primarily used in construction, real estate, and other industries that undertake large projects that span over extended periods. The method estimates the percentage of work completed, and then assigns that percentage of revenue and expenses to that period.

Under the percentage of completion method, revenue and expenses are recognized proportionally to the progress of the project, and the calculation is based on the cost incurred to date relative to the total estimated cost of the project.

This method is advantageous because it allows for more accurate financial statements that reflect the actual progress and costs of the project.

Overall, the percentage of completion method provides a more accurate representation of the financial position of long-term projects and contracts, and is therefore an essential tool for companies in industries that undertake such projects.

Answer:

$14,498.1

Step-by-step explanation:

To find the amount Rob will have in 5 years with compound interest, we can use the formula:

A = P (1 + r/n)^(nt)

where:

A = the future value of the investment

P = the principal amount invested

r = the annual interest rate (as a decimal)

n = the number of times the interest is compounded per year

t = the number of years

In this case, we have:

P = $7,869 (the principal amount)

r = 13% or 0.13 (the annual interest rate)

n = 1 (the interest is compounded annually)

t = 5 (the number of years)

Substituting these values into the formula, we get:

A = $7,869 (1 + 0.13/1)^(1*5)

A = $7,869 (1.13)^5

A = $14,964.92

Therefore, to the nearest cent, Rob will have $14,964.92 in 5 years.

Factor trees are a means to represent a number's factors, more precisely, a number's prime factorization. The tree's branches are divided up into components.

The new average salary of the people on the bus is $84,44,96,111.11  and the median salary will not change and will remain same.

Given, we know that average salary of the 9 people on the bus is $65,000.

Formula for Average = sum of salary of all people/ the number of people.

Let us say average salary of first 8 people is 'S'. Given, salary of the 9th guy on the bus is $120,000 Now, we can write it like this :

⇒$65,000  = (S + $120,000)/9

⇒585,000 = S + $120,000

⇒S = $465,000

Therefore, average salary of 8 people is $465,000 after the 9th guy gets off. Now Bill Gates enters the bus with a salary of $7,600,000,000. New average salary :

⇒ (S + $7,600,000,000) / 9

The number [square] can divided exactly by six. and when [square] is divided by five, four is the number left over is:

12, 42, 72 o 102

The number [square] can be represented as 6x, where x is any positive integer, since it can be divided exactly by six. When [square] is divided by five, four is the number left over. Therefore, we can write the equation:

6x = 5y + 4

Where y is any positive integer. We can rearrange the equation to solve for x:

6x - 4 = 5y

2x - 2 = (5/3)y

2x - 2 = (5/3)(3x/5)

The correct option is A: A linear pair is two adjacent, supplementary angles.

Supplementary angles are a pair of angles whose measures add up to 180 degrees. In other words, if we place two angles side by side, and their measures add up to 180 degrees, then they are said to be supplementary.

For example, if we have an angle with a measure of 120 degrees, then its supplementary angle would have a measure of 60 degrees, since 120 + 60 = 180. It's important to note that the two angles in a pair of supplementary angles do not have to be adjacent, meaning they can be located anywhere in a figure, as long as their measures add up to 180 degrees.

Supplementary angles play an important role in geometry and mathematics, especially when it comes to solving problems involving angles. For instance, if we know that two angles are supplementary, and we know the measure of one of the angles, we can easily calculate the measure of the other angle by subtracting the known measure from 180 degrees.

In addition, supplementary angles are often used in real-life situations, such as when designing buildings, bridges, or other structures that require precise measurements of angles. Overall, understanding the concept of supplementary angles is crucial for anyone who wants to study and understand geometry and mathematics.

David has drawn a total of 177 cm of lines.

We can use the Pythagorean theorem, which tells us that in a right triangle, the square of the length of the hypotenuse (the diagonal line) is equal to the sum of the squares of the lengths of the other two sides (the lines along the long edge and the width).

In this case, the length of the hypotenuse is the distance from the starting corner to the end of the diagonal line, which we can calculate as follows:

d = √(77² + 36²) ≈ 85.99 cm

Therefore, David has drawn a total of 77 cm + 36 cm + 85.99 cm = 198.99 cm of lines. However, we should subtract the length of the starting corner to the end of the first line, which is 77 cm, since it was counted twice (once as part of the diagonal line and once as part of the line along the long edge).

So, the total length of lines that David has drawn is 77 cm + 36 cm + 85.99 cm - 77 cm = 177 cm.

Pythagoras' theorem is a fundamental theorem in mathematics that relates to the sides of a right triangle. It states that in any right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides.

This can be expressed as:

a² + b² = c²

where a and b are the lengths of the two legs of the right triangle, and c is the length of the hypotenuse.

Pythagoras' theorem can be used to solve a variety of problems involving right triangles, such as finding the length of a missing side or determining whether a triangle is a right triangle. It is also the basis for the distance formula in two and three-dimensional Euclidean space.

num_cols = arr.shape[1]

# create a list of column indices

col_indices = np.arange(num_cols)

# shuffle the column indices randomly

shuffled_col_indices = np.random.permutation(col_indices)

# use the shuffled column indices to reorder the columns in the array

arr_shuffled = arr[:, shuffled_col_indices]

# print the original array and the shuffled array

print("Original array:")

The slope of the line tangent to the parabola's y-intercepty = [tex](x+2)^2-4[/tex] is 4.

We must first get the parabola's y-intercept in order to determine the slope of the line tangent to it.

We enter x=0 into the equation to obtain the y-intercept:

[tex]y = (x + 2)^2 - 4[/tex]

[tex]y = (0 + 2)^2 - 4[/tex]

y = 4 - 4

y = 0

Hence, the parabola's y-intercept is (0, 0).

The derivative of the parabola's equation must then be determined.

[tex]y = (x + 2)^2 - 4\\y = x^2 + 4x + 4 - 4\\y = x^2 + 4x[/tex]

dy/dx = 2x + 4

By adding x=0 to the derivative, we can now get the slope of the tangent line to the y-intercept:

dy/dx = 2x + 4

dy/dx = 2(0) + 4

dy/dx = 4

Hence, the slope of the line tangent to the parabola's y-intercepty = [tex](x+2)^2-4[/tex] is 4.
