Johnson Industries purchased a metal-working lathe for $38,000. This item will be used for business 90% of the time. Accountants elected to take a $18,000 section 179 deduction and utilize the special depreciation allowance of 50%.
Prepare a depreciation schedule (in $) using MACRS.
Round all dollar amounts to the nearest cent.

Answers

The depreciation schedule (in dollars) using MACRS for the metal-working lathe is as follows:

Year 1: $1,429.00

Year 2: $2,449.00

Year 3: $1,749.00

Year 4: $1,249.00

Year 5: $893.00

Year 6: $892.00

Year 7: $893.00

What is the MACRS depreciation schedule?

The depreciation schedule using the Modified Accelerated Cost Recovery System (MACRS) is prepared as follows:

Given data:

Purchase cost of the metal-working lathe: $38,000

Business use percentage: 90%

Section 179 deduction: $18,000

Special depreciation allowance: 50%

Depreciable basis = Purchase cost - Section 179 deduction

Depreciable basis = $38,000 - $18,000 = $20,000

Special depreciation allowance = $20,000 * 50%

Special depreciation allowance  = $10,000

Adjusted depreciable basis = $20,000 - $10,000

Adjusted depreciable basis  = $10,000

The recovery period for a metal-working lathe is 7 years.

Using MACRS, the depreciation rates for a 7-year recovery period are as follows:

Year 1: 14.29%

Year 2: 24.49%

Year 3: 17.49%

Year 4: 12.49%

Year 5: 8.93%

Year 6: 8.92%

Year 7: 8.93%

Annual depreciation expense = Adjusted depreciable basis * Depreciation rate

Year 1:

Depreciation expense = $10,000 * 14.29% = $1,429.00

Year 2:

Depreciation expense = $10,000 * 24.49% = $2,449.00

Year 3:

Depreciation expense = $10,000 * 17.49% = $1,749.00

Year 4:

Depreciation expense = $10,000 * 12.49% = $1,249.00

Year 5:

Depreciation expense = $10,000 * 8.93% = $893.00

Year 6:

Depreciation expense = $10,000 * 8.92% = $892.00

Triangle FGH is inscribed in circle O, the length of radius OH is 6, and maFGH-20. What is the area of the sector formed by angle FOH, in terms of pi 1) 2k 2) 3/2 (3) 4

PLEASE HELP ME, NO FAKE ANSWERS​ (sorry that it's blurry)

Answers

Triangle FGH is inscribed in circle O, the length of radius OH is 6, and ma FGH-20. The area of the sector formed by angle FOH, in terms of pi is 6π. Hence, it is neither of the options.

Given that triangle FGH is inscribed in circle O, the length of radius OH is 6, and m∠FGH = 20.

We have to find the area of the sector formed by angle FOH, in terms of pi.

Using the central angle, we know that the measure of ∠FOH is twice that of ∠FGH, which is 40°.

Therefore, the measure of the central angle FOH is 2 * 40 = 80°.

The area of the sector formed by angle FOH, in terms of pi is given by, A = r²θ/2 where A = Area of the sector, r = radius of the circle and θ = central angle in radians.

To calculate the value of A in terms of pi, we have to convert the central angle from degrees to radians.

1 radian = 180°/π radians

Therefore, 80° = 80° * (π/180°) = 4π/9 radians.

Now we can plug in the given values of r and θ to find the area of the sector.

A = (6)² * (4π/9) / 2 = 18π/3 = 6π

Thus, the area of the sector formed by angle FOH, in terms of pi is 6π.

Hence, option 1) 2k is incorrect. Option 2) 3/2 (3) is incorrect. Option 3) 4 is incorrect. Answer: 6π.

Answers

The marked price (M.P.) is 1,72,000 when the selling price is 1,61,680 with discount of 6%.

To find the marked price (M.P.), we can use the formula:

M.P. = S.P. / (1 - D%)

Given:

S.P. = 1,61,680

D% = 6%

First, we need to convert the discount percentage to decimal form by dividing it by 100:

D% = 6/100 = 0.06

Now, we can substitute the values into the formula:

M.P. = 1,61,680 / (1 - 0.06)

M.P. = 1,61,680 / 0.94

M.P. = 1,72,000

Therefore, the marked price (M.P.) is approximately 1,72,000.

Answers

Answer:

Is 03.841

Step-by-step explanation:

To find the critical value needed to test the claim that the sentence is independent of the plea, we need to perform a chi-square test of independence. The critical value is based on the significance level (α) and the degrees of freedom.

In this case, the given significance level is 0.05. Since the table represents a 2x2 contingency table (two categories for plea and two categories for sentence), the degrees of freedom (df) can be calculated as (number of rows - 1) * (number of columns - 1) = (2 - 1) * (2 - 1) = 1.

To find the critical value at a significance level of 0.05 with 1 degree of freedom, we consult a chi-square distribution table or use statistical software.

The critical value for a chi-square test with 1 degree of freedom and a significance level of 0.05 is approximately 3.841.

Therefore, the correct answer is 03.841.

A passenger train leaves depot 2 hours after a freight train leaves the same depot. The freight train is traveling 18 mph slower than the freight train find the rate of each train if the passenger train over, takes the freight train in 3 hours

Answers

Answer:

The passenger train is traveling at 45 mph, and the freight train is traveling at 27 mph.

Step-by-step explanation:

Let's assume the speed of the passenger train is represented by x mph.

According to the given information, the freight train leaves the depot 2 hours before the passenger train. Therefore, when the passenger train starts, the freight train has already been traveling for 2 hours.

Let's represent the speed of the freight train as (x - 18) mph, which is 18 mph slower than the passenger train.

Now, we know that the passenger train overtakes the freight train in 3 hours. This means that the passenger train traveled for 3 hours, while the freight train traveled for 3 + 2 = 5 hours.

Since speed = distance/time, we can set up the following equation based on the distances covered by each train:

Distance covered by passenger train = Distance covered by freight train

Using the formula, distance = speed × time, we get:

x × 3 = (x - 18) × 5

Simplifying the equation:

3x = 5x - 90

90 = 5x - 3x

90 = 2x

Dividing both sides by 2:

45 = x

So, the speed of the passenger train is 45 mph.

The speed of the freight train is 45 - 18 = 27 mph.

By definition, theoretical probability is equal to:

B. No. of total outcomes/ total no. of impossible outcomes
C. No. of possible outcomes/ total no. of favorable outcomes
D. No. of total outcomes/ total no. of possible outcomes

Answers

Theoretical probability is defined as the ratio of the number of favorable outcomes to the total number of possible outcomes, making option A the correct answer.

The correct answer is A. Theoretical probability is defined as the ratio of the number of favorable outcomes to the total number of possible outcomes. It represents the likelihood of an event occurring based on mathematical calculations and assumptions.

To provide a detailed explanation, let's break down the components of the definition:

Favorable outcomes: These are the outcomes that meet the desired criteria or event you are interested in. For example, if you are rolling a fair six-sided die and you want to find the probability of rolling a 3, the favorable outcome would be a single outcome where the die shows a 3.

Total number of possible outcomes: This refers to the complete set of all possible outcomes in the given situation. In the case of the fair six-sided die, there are six possible outcomes (numbers 1 to 6) since each face of the die represents a different number.

Theoretical probability is then calculated by dividing the number of favorable outcomes by the total number of possible outcomes. This ratio provides an estimate of the probability of the event occurring under ideal, theoretical conditions. It assumes that each outcome is equally likely to occur.

It's worth noting that theoretical probability is based on mathematical calculations and assumptions, and it may not always reflect the actual probability observed in real-world scenarios. However, it serves as a foundation for understanding and analyzing probabilities in various contexts, such as in mathematics, statistics, and decision-making processes.

Robert has some nickels and some dimes. He has a maximum of 29 coins worth no less than $2.20 combined. If Robert has 10 nickels, determine all possible values for the number of dimes that he could have. Your answer should be a comma separated list of values. If there are no possible solutions, submit an empty answer.

Answers

Let's solve this problem step by step.

Robert has 10 nickels, which means he already has 10 coins. We need to find the possible values for the number of dimes he could have.

Let's assume Robert has x dimes.

The value of 10 nickels is 10 * $0.05 = $0.50.
The value of x dimes is x * $0.10 = $0.10x.

The total value of the coins is at least $2.20. So we can write the inequality:

$0.50 + $0.10x ≥ $2.20

Now let's solve this inequality for x:

$0.10x ≥ $2.20 - $0.50
$0.10x ≥ $1.70
x ≥ $1.70 / $0.10
x ≥ 17

Therefore, the possible values for the number of dimes Robert could have are 17 or greater.

So, the comma-separated list of possible values for the number of dimes is: 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29.

Note: We have considered the maximum limit of 29 coins mentioned in the problem, so any value of x greater than or equal to 17 and less than or equal to 29 would satisfy the given conditions.
Final answer:

Robert's dimes are anywhere between 17 and 19.

Explanation:

Nickels

are worth 5 cents, and

dimes

are worth 10 cents. Since Robert has 10 nickels, he already has 50 cents. To reach a minimum of $2.20, or 220 cents, Robert needs at least 170 more cents. Because each dime is worth 10 cents, he needs a minimum of 17 dimes. If he has a maximum of 29 coins in total, subtracting the 10 nickels means that he can have up to 19 dimes. So, Robert could have anywhere between 17 and 19 dimes.

The area of the shaded region is  104 cm²

How to determine the area

First, we need to know that the area of a circle is calculated using the formula;

A = πr²

Such that the parameters of the formula are;

A is the area of the circler is the radius

First, let us find the area of the small circle

Area = 3.14 × 4²

Find the square value and multiply, we have;

Area = 50.24cm²

Area of the large circle = 3.14 × 7²

Find the square value and multiply

Area = 153. 86cm²

Area of the shaded region = Area of large circle - area of small circle

= 153.86 - 50.24

= 104 cm²

round 3666042 to the nearest hundred thousand​

3666042 to the nearest hundred thousand is 3,700,000

an online store begins selling a new kind of baskelballshoe. At week zero, 30 pairs of shoes were sold.
In week 3, the store sold 240 pairs of shoes. Write an exponential model that relates the number of shoes sold to the week number, and use the model to predict how many shoes will be sold during week 7.

Answers

Answer:

3840 pairs of shoes

Step-by-step explanation:

To write an exponential model that relates the number of shoes sold to the week number, we can use the general form of an exponential function:

y = a * b^x

where:

y is the number of shoes sold,

x is the week number, and

a and b are constants to be determined.

Given the information:

In week 0, 30 pairs of shoes were sold.

In week 3, 240 pairs of shoes were sold.

We can use these two data points to determine the values of a and b.

Using the data point for week 0:

30 = a * b^0

30 = a

Using the data point for week 3:

240 = 30 * b^3

8 = b^3

b = 2 (taking the cube root of both sides)

Therefore, the exponential model that relates the number of shoes sold to the week number is:

y = 30 * 2^x

To predict the number of shoes sold during week 7, we substitute x = 7 into the model:

y = 30 * 2^7

y = 30 * 128

y = 3840

Therefore, the model predicts that 3840 pairs of shoes will be sold during week 7.

E. 32% of people who prefer plan I are from the 36–45 age group, and 42% of people from the 46–55 age group prefer plan II.

Answers

The Percentage of people from the 46-55 age group preferring Plan II is 42%.

The percentages, we need to calculate the ratio of people preferring Plan I in the 36-45 age group and the ratio of people preferring Plan II in the 46-55 age group.

Let's start with the first part of the question:

Percentage of people preferring Plan I from the 36-45 age group:

To calculate this percentage, we need to divide the number of people preferring Plan I in the 36-45 age group by the total number of people preferring Plan I, and then multiply by 100 to express it as a percentage.

Number of people preferring Plan I in the 36-45 age group = 14

Total number of people preferring Plan I = 14 + 28 + 21 = 63

Percentage = (14 / 63) * 100 ≈ 22.22 ≈ 22% (rounded to the nearest whole number)

So, the percentage of people preferring Plan I from the 36-45 age group is approximately 22%.

Now, let's move on to the second part of the question:

Percentage of people from the 46-55 age group preferring Plan II:

To calculate this percentage, we need to divide the number of people preferring Plan II in the 46-55 age group by the total number of people from the 46-55 age group, and then multiply by 100 to express it as a percentage.

Number of people preferring Plan II in the 46-55 age group = 21

Total number of people in the 46-55 age group = 27 + 21 + 2 = 50

Percentage = (21 / 50) * 100 = 42%

So, the percentage of people from the 46-55 age group preferring Plan II is 42%.

Based on the calculations, the correct answer is:

A. 23% of people who prefer Plan I are from the 36-45 age group, and 42% of people from the 46-55 age group prefer Plan II.
