Answers

To calculate the gain on the sale of the office furniture, we need to determine the asset's book value and compare it to the sale price.

First, let's calculate the accumulated depreciation on the furniture. The furniture was purchased on January 1, 2014, and the straight-line depreciation method is used over 10 years with a salvage value of $80,200.

Depreciation per year = (Cost - Salvage Value) / Useful Life

Depreciation per year = ($746,800 - $80,200) / 10 years

Depreciation per year = $66,160

Next, we need to calculate the accumulated depreciation for the period from January 1, 2014, to May 1, 2021 (the date of the sale). This is approximately 7.33 years.

Accumulated Depreciation = Depreciation per year × Years

Accumulated Depreciation = $66,160 × 7.33 years

Accumulated Depreciation = $484,444.80

Now, we can calculate the book value of the furniture:

Book Value = Cost - Accumulated Depreciation

Book Value = $746,800 - $484,444.80

Book Value = $262,355.20

Finally, we can calculate the gain on the sale:

Gain on Sale = Sale Price - Book Value

Gain on Sale = $300,000 - $262,355.20

Gain on Sale = $37,644.80

Therefore, the gain that should be recognized on the sale of the office furniture is approximately $37,644.80.

The gain that should be recognized on the sale of the office furniture is $84,080.

The gain is calculated by subtracting the equipment's book value from the sale price. This gain will be reported on the company's income statement. Here is how to calculate the gain:First, find the equipment's book value using the straight-line method of depreciation.

Straight-line depreciation is calculated by taking the difference between the equipment's original cost and its salvage value, and then dividing it by the number of years the equipment is used. The annual depreciation expense is then multiplied by the number of years the equipment is used to find the equipment's book value at the end of its useful life.

For this question, the book value of the equipment at the time of sale is:Cost of equipment: $746,800Salvage value: $80,200Depreciable cost: $746,800 - $80,200 = $666,600Annual depreciation: $666,600 ÷ 10 years = $66,660Book value at the end of 2020: $666,600 - ($66,660 x 7) = $156,420

Next, subtract the equipment's book value from the sale price to find the gain:Sale price: $300,000Book value: $156,420Gain: $143,580Finally, round the gain to the nearest dollar:$143,580 ≈ $143,580.00So the gain that should be recognized on the sale of the office furniture is $84,080.

The statement that is NOT correct about hypothesis testing is: "We cannot eliminate both type l error and type II error at the same time."

In hypothesis testing, we aim to make a decision about a population parameter based on sample data. Type I error refers to rejecting a true null hypothesis, while Type II error refers to failing to reject a false null hypothesis. While it is not possible to completely eliminate both types of errors simultaneously, we can minimize the chances of committing either of them by choosing an appropriate significance level and conducting a power analysis.

Find the inclination of the line whose slope is of -5/2

Answers

The inclination of the line with a slope of -5/2 is approximately 111.8°.

To find the inclination of the line whose slope is -5/2, follow these steps:

1. Recall the definition of the slope: the tangent of the angle of inclination (θ) is equal to the slope (m). In this case, m = -5/2. So, tan(θ) = -5/2.
2. To find the angle of inclination (θ), take the inverse tangent (arctan) of the slope. θ = arctan(-5/2).
3. Use a calculator to find the angle in degrees: θ ≈ -68.2°.

Since the inclination should be between 0° and 180°, add 180° to the negative angle: θ = -68.2° + 180° = 111.8°.

So, the inclination of the line with a slope of -5/2 is approximately 111.8°.

find the net change in the value of the function between the given inputs. f(x) = 6x − 5; from 1 to 6

Answers

The net change in the value of the function between x = 1 and x = 6 is 30.

To find the net change in the value of the function between the inputs of 1 and 6, we need to find the difference between the output values of the function at x = 1 and x = 6, and then take the absolute value of that difference.

First, we can find the output value of the function at x = 1:

f(1) = 6(1) - 5 = 1

Next, we can find the output value of the function at x = 6:

f(6) = 6(6) - 5 = 31

The net change in the value of the function between x = 1 and x = 6 is the absolute value of the difference between these two output values:

keiko tosses one penny and ephraim tosses two pennies. what is the probability that ephraim gets the same number of heads that keiko gets? express your answer as a common fraction.

Answers

The probability that Ephraim gets the same number of heads that Keiko gets is 3/8.

What is probability?

The proportion of favorable cases to all possible cases is used to determine how likely an event is to occur.

Here, we

Let K(n) be the probability that Keiko gets n heads, and let E(n) be the probability that Ephriam gets n heads.

K(0) = 1/2

K(1) =1/2

K(2) = 0 (Keiko only has one penny!)

E(0) = 1/2 ×1/2 = 1/4

E(1) =  1/2 ×1/2 +  1/2 ×1/2 = 1/2  (because Ephraim can get HT or TH)

E(2) =  1/2 ×1/2 = 1/4

The probability that Keiko gets 0 heads and Ephriam gets 0 heads is K(0)×E(0). Similarly for 1 head and 2 heads.

We get

P = K(0)× E(0) + K(1)×E(1) + K(2)× E(2)

P = 1/2 ×1/4 + 1/2 ×1/2 +0

P = 3/8

Hence, the probability that Ephraim gets the same number of heads that Keiko gets is 3/8.

Why is it called an asymptote?

Answers

An asymptote function is called such because it is a line that a curve approaches but never touches, or "asymptotically" approaches.

An asymptote is a line that a curve approaches but never actually touches. It is called an asymptote because the word comes from the Greek asymptōtos, which means "not falling together." Asymptotes are used in mathematics to describe curves that approach a particular line without ever intersecting it. For example, in a graph of a function, an asymptote is a line that the graph of the function approaches, but never intersects with, as it approaches infinity. Asymptotes are also used to describe straight lines in a plane that approach each other at a certain angle, but never meet. In both cases, the idea is that the line or curve approaches the asymptote, but never actually touches it, thus the name asymptaote.

Answer:

angle 1 = 54° because this angle is a vertical angle of 54°, and vertican angles are always the same.

angle 2 = 126° because straight line = 180°, and there we have 54°, so 180-54=126°

angle 3 = 126° because this angle is vertical angle to 126°

angle 4 = 121° because this angle is alternative interior angle of the sum of the angles 12(54) and 67°

angle 5 = 59° because angle 5 and angle 4 makes a straight line, staring line = 180°, and 180°-angle 4(121°)= 59°

angle 6 = 121° because this anle is vertican angle of 121°

angle 7 = 59 because this angle is vertical angle of 59°

angle 8 = 59° because this angle is corresponding to angle 5 (59°), and corresponding angles are always the same

angle 9 = 54° because this angle is corresponding angle to 54°

angle 10 = 67 because angle 10, 9 and 8 creates straight line, straight line = 180°, angle 9(54) + angle 8(59)=113, and 180°-113°=67°, that means that angle 10 = 67°

angle 11 = 59 because this angle is corresponding to angle 7 (59°)

angle 12 = 54° because this angle is corresponding angle to angle 1 (54°)

that is it :)

We will get that the angle theta is:

θ = β/2

How to find the value of theta?

Remember that the sum of the interior angles of any triangle must be equal to 180°.

Now, looking at the triangle in the left, we can see that the top angle is equal to:

180 - 2α

The right angle is equal to:

180 - 2β

And the left angle is α

Then we can write:

α + (180 - 2α) + (180 - 2β) = 180

-α - 2β = -180

α = 180 - 2β

Now we can go to the other triangle, where theta is, and write:

α + β + 2θ = 180

Replacing what we found above, we get:

180 - 2β + β + 2θ = 180

-β + 2θ = 0

θ = β/2

That is the best simplification we can get with the given diagram.

Cam’s tent (shown below) is a triangular prism.
Find the surface are, including the floor of his tent
PLEASE HELP

Cams tent (shown below) is a triangular prism.Find the surface are, including the floor of his tentPLEASE

Answers

Answer:

21.4 m²

Step-by-step explanation:

To find the surface area of this whole triangular prism, we have to look at the bases (the triangles), find their surface area, then look at the sides (the rectangles) and find theirs.

Let's start with the triangles. The area of any triangle is \(\frac{bh}{2}\). The base of this triangle is 2m (because there are 2 one meters) and the height is 1.7m.

\(\frac{2\cdot1.7}{2} = \frac{3.4}{2} = 1.7\)

So the area of one of these triangles is 1.7m. Multiplying this by two, because there are two triangles in this prism:

\(1.7\cdot2=3.4\)

Now let's find the area of the sides.

The side lengths are 2 and 3, so

\(2\cdot3=6\), and there are 3 sides (including the bottom/floor) so \(6\cdot3=18\).

Now we add.

\(18+3.4=21.4\) m².

find the center and radius of the sphere whose equation is given by x2+y2+z2+4x−2z−8=0

Answers

To find the center and radius of the sphere whose equation is given by x²+y²+z²+4x−2z−8=0, follow these steps:


Step 1: Rewrite the given equation in the standard form of a sphere.
The standard form of a sphere's equation is (x-a)²+(y-b)²+(z-c)²=r², where (a, b, c) is the center and r is the radius.



Step 2: Complete the squares for the x and z terms.
(x²+4x)+(y²)+(z²-2z)=8
(x+2)²-4+(y²)+(z-1)²-1=8


Step 3: Move the constants to the other side of the equation.
(x+2)²+(y²)+(z-1)²=13



Now the equation is in standard form. We can identify the center and radius. Step 4: Identify the center and radius.
The center (a, b, c) = (-2, 0, 1), and the radius r = √13. So, the center of the sphere is (-2, 0, 1), and the radius is √13.

Hope this helps.

If there is something wrong, please let me know.

Proportional reasoning refers to the ability to compare and analyze relationships between two or more quantities that change in a consistent way. It involves understanding the concept of proportionality and applying it to solve problems.

1.) If a business jet burns 300 gallons of gasoline per hour, it burns 900 gallons of gasoline in a three-hour flight. This can be calculated by multiplying the burn rate of 300 gallons per hour by the duration of the flight, which is three hours.

2.) On average, one gallon of gasoline weighs approximately six pounds. Therefore, fifty gallons of gasoline weighs 300 pounds. This can be calculated by multiplying the weight of one gallon (six pounds) by the quantity of fifty gallons.

3.) For every one yard, there are thirty-six inches. To find the number of yards in 2,124 inches, we divide 2,124 by 36. The result is 59 yards. This can be calculated by dividing the total number of inches by the conversion factor of thirty-six inches per yard.

4.) A person who weighs 240 pounds burns 180 calories per mile of running. A person who weighs 48 pounds, burns thirty-six calories while running one mile. To find the number of pounds for which the person burns thirty-six calories while running one mile, we can set up a proportion. If we let x represent the weight in pounds, the proportion would be: 240 pounds / 180 calories = x pounds / 36 calories. Solving for x gives us x = 48 pounds.

5.) A rice casserole recipe serves four people and requires two tablespoons of butter. If a rice casserole requires six tablespoons of butter, it serves twelve people. This can be determined by setting up a proportion: 4 people / 2 tablespoons = 12 people / 6 tablespoons. Solving for the unknown number of people gives us 12 people.
