3   $30,000   $19,200          $10,800          $4,320         $23,520   $6,480

The double-declining-balance method is a depreciation method that allocates more cost to the earlier years of the asset's life.

The double-declining-balance method uses twice the straight-line rate and is computed as the product of 100/estimated useful life multiplied by 2.

The double rate is applied at the end of the year's balance for each year's depreciation expense.

The difference between the previous year's ending balance and the residual value is taken as the depreciation expense for the last year.

Auto = $30,000

Estimated life = 5 years

Residual value = $800

Depreciable amount = $29,200 ($30,000 - $800)

Straight-line depreciation rate = 20% (100/5)

Double-declining depreciation rate = 40% (20% x 2)

1st year = $12,000 ($30,000 x 40%)

2nd year = $7,200 ($18,000 x 40%)

3rd year =  $4,320 ($10,800 x 40%)

4th year = $2,592 ($6,480  x 40%)

5th year = $3,088 ($3,888 - $800)

Answer: A scale factor of 1/2 was applied to the first triangle to get the resulting image.

Step-by-step explanation: The initial side length of 3.4 is twice as long as 1.7, the initial triangle was reduced to half of the initial size.

Answer:

The triangle is still an equilateral triangle as before, and the only difference is that the side length is halved from 3.4 to 1.7 (3.4/2=1.7). Therefore, the scale factor is 1.7/3.4=0.5. A scale factor <1 means that the original shape is reduced. The scale factor would be a reduction.

Ordinarily, the MACRS (modified accelerated cost recovery system) depreciation method is the tax-allowed method that ensures that larger deductions for depreciation expense or cost recovery are made in the beginning years and lower deductions for later years.

However, the same deductions are made each year when the straight-line method is used.

The depreciation expense using the MACRS straight-line method is computed by dividing the asset's cost by the recovery year.

Plan 1 charges a one-time fee of $145.00 for admission plus $5.00 every trip for parking. Plan 2 charges a one-time fee of $40.00 for parking plus $12.00 every trip for admission.

So, this will make an arithmetic progression.

The formula to find nth term of an A.P:

an = a+(n-1)d where a is the first term

Now, on left hand side, we have nth term for plan A and on the right hand side, we have the nth term for plan B because their nth term will be equal.

145+(n-1)5 = 40+(n-1)12

145+5n-5 = 40+12n-12

The real​ after-tax interest​ rate is -0.0096%, if the inflation rate rises to 4%

The real interest rate is the interest rate received by an investor, saver, or lender after adjusting for inflation. The Fisher equation, which indicates that the real interest rate is roughly the nominal interest rate minus the inflation rate, can be used to define it more explicitly.

For example, if an investor could lock in a 5% interest rate for the future year and expected a 2% increase in prices, they would receive a 3% real interest rate.

Because different investors forecast different levels of future inflation, the expected real interest rate is not a single number. Because the inflation rate during the life of a loan is unknown at the outset, inflation volatility represents a risk.

Given,

The income tax rate is 50%

After tax rate=Nominal return×(1- tax rate)

=0.06(1-0.5)

=0.03=3%

Inflation rate raises to 4% then,

=(1+ rate interest)/(1+Inflation rate)-1

=(1+0.03)/(1+0.04)-1

A total of 9 workers are needed to finish the same task in 4 days

From the question, we understand that:

3 workers can complete a certain task in 12 days

This means that

3 workers = 12 days

The proportionality constant is then calculated as

Proportionality constant = Number of workers x Number of days

Substitute the known values in the above equation So, we have the following equation

Proportionality constant = 3 * 12

Evaluate

Proportionality constant = 36

When the number of days is 4, we have

Days = 4

So, we have

Proportionality constant = Number of workers x Number of days

This gives

36 = Number of workers x 4

Divide both sides by 4

Number of workers = 9

Hence, the number of workers is 9

By using the fact that the angles are supplementary, we can write and solve a linear equation to find that x = 62.

In the image, we can see two supplementary angles, where by definition, two angles are supplementary if their addition is equal to a plane angle (an angle of 180°).

With that in mind, we can write the linear equation:

x + 118 = 180

So we just need to isolate x in that simple linear equation.

If we subtract 118 in both sides, we will get:

x + 118 - 118 = 180 - 118

Using the probability of adults of having tattoo, critical value is 1.76 and margin of error is 0.0353 and a 95% confidence interval for the proportion of all adults that have a tattoo is (0.2347, 0.3053)

In the given question,

In a poll of 489 adults, 132 of then said they have a tattoo.

We have to find critical value and margin of error, and then construct a 95% confidence interval for the proportion of all adults that have a tattoo.

From the question

Total number of adults = 489

The adults that have tattoo = 132

So the proportion in the sample is

p = 132/489

p = 0.269

p ≈ 0.27

Now finding the proportion of adults not having tattoo.

q = 1−p

q = 1−0.27

q = 0.73

Now finding the critical value(z).

The value of z from the standard table for 95% confidence interval.

We can write 95% as 0.95

Z = [tex]z_{\alpha /2}[/tex]

Z = [tex]z_{0.95 /2}[/tex]

Z = [tex]z_{0.475}[/tex]

From the standard table of z

Z = 1.96.

Now finding the margin error.

Margin Error(E) = [tex]Z\times\sqrt{\frac{pq}{n}}[/tex]

As we know that Z = 1.96, p = 0.27, q = 0.73, n = 489

Now putting the value

E = [tex]1.76\times\sqrt{\frac{0.27\times0.73}{489}}[/tex]

Simplifying

E = [tex]1.76\times\sqrt{\frac{0.1971}{489}}[/tex]

E = [tex]1.76\times\sqrt{0.000403}[/tex]

E = 1.76×0.0201

E = 0.0353

Now finding a 95% confidence interval for the proportion of all adults that have a tattoo.

Confidence Interval = p−E< P < p+E

Confidence Interval = 0.27−0.0353< P < 0.27+0.0353

Confidence Interval = 0.2347< P < 0.3053

Hence, critical value is 1.76 and margin of error is 0.0353 and a 95% confidence interval for the proportion of all adults that have a tattoo is (0.2347, 0.3053)

The probability that a student's mark is more than 75 is 0.0947 and in a class of 50 students, 5 students should have a mark of more than 75.

In the given question,

The Mathematics marks of all the students in the class are normally distributed with mean mark 54 and standard deviation 16.

We have to find the probability that a student's mark is more than 75.

In a class of 50 students, we also have to find how many students should have a mark of more than 75.

From the question the mean = 54

Standard Deviation = 16

So the probability that a student's mark is more than 75.

Using the normal distribution

z = (x−mean)/Standard Deviation

P(x>75) = P(z>(x−mean)/Standard Deviation)

P(x>75) = 1−P(z<(75−54)/16)

Simplifying

P(x>75) = 1−P(z<21/16)

P(x>75) = 1−P(z<1.3125)

From the standard z table value

P(x>75) = 1−0.9053

P(x>75) = 0.0947

Hence, the probability that a student's mark is more than 75 is 0.0947.

Now finding in a class of 50 students, how many students should have a mark of more than 75.

Total student = 50

So the student having mark of more than 75 = Total student * probability that a student's mark is more than 75

The student having mark of more than 75 = 50 * 0.0947

The student having mark of more than 75 = 4.735

The student having mark of more than 75 ≈ 5

Hence, in a class of 50 students, 5 students should have a mark of more than 75.

The value of x is 33 and y is 39.

The fundamental characteristics listed below make it simple to recognise parallel lines.

As, (7x- 7) = 3x+ 45 (corresponding angles)

4x = 52

x= 13

Now, 7x- 7 + w + 63 = 180 (linear pair)

w= 180- 147

w= 33 degree.

y-6 = 33 (Alternate interior angle)

y= 39

Hence, the value of x is 33 and y is 39.

If the temperatures on Earth continue to increase, the change in the pie graph would be C. Less than 2% of the Earth's water will be in polar ice caps.

The temperature of Earth has risen significantly in the last century as a result of human activity. This had led to the loss of polar ice caps due to them having melted into the oceans from the high temperatures.

This means that if the temperature of the planet should continue to increase, the polar ice caps we have will further be depleted. This would lead to less than 2% of the Earth comprising polar ice caps as is the case now.
