The value for x is 10.9 units.

According to the Angle Bisector Theorem, a triangle's angle bisector cuts through the other side of the triangle so that the ratio of the two line segments is equal to the ratio of the other two sides.

Given:

In triangle ABC, AD is the angle bisector of <BAC.

Using the Angle bisector theorem

So, AB/ AC = BD / BC

25/ 21 = x/ (20- x)

25(20-x) = 21 x

500 - 25x = 21x

500 = 46x

x= 10.9

To convert 4 hours and 45 minutes to a fraction, we need to first convert the minutes to hours by dividing by 60 and then add the result to the 4 hours.

4 hours and 45 minutes = 4 + 45/60 hours = 4 + 0.75 hours

Now, we can write this as a fraction by expressing the decimal part as a fraction:

4 + 0.75 = 4 + 3/4 = (4*4 + 3)/4 = 19/4

Therefore, 4 hours and 45 minutes is equal to 19/4 when expressed as a fraction in simplest form.

The answer is (B) 4 3/4.

The statement 'In order to calculate MACRS depreciation, the business needs to know the asset's original cost, the depreciation period, and which depreciation method (i.e. 200% declining balance) is used.' is false. because, the asset was used for both personal and business purposes, the business must calculate the percentage of business use in order to determine the correct depreciation deduction.

While the asset's original cost, depreciation period, and depreciation method are all necessary inputs for calculating MACRS depreciation, there are other pieces of information that are also required.

For example, the business must determine the applicable MACRS recovery period and the property's placed-in-service date, as well as any applicable conventions for calculating the depreciation.

Additionally, if the asset was used for both personal and business purposes, the business must calculate the percentage of business use in order to determine the correct depreciation deduction.

Answer:

72.3 - 39.1 = 4tens - 7ones + 2tenth

Step-by-step explanation:

Give the expression 72.3 + (-39.1)

opening the parenthesis:

= 72.3 + (-39.1)

= 72.3 - 39.1

Breaking the decimal values into place values

72.3 = 7tens + 2units + 3tenth

72.3 = 7(10)+2(1)+3(1/10)

72.3 =70+2+0.3

Similarly for 39.1

39.1 = 3tens + 9units + 1tenth

39.1 = 3(10)+9(1)+1(1/10)

39.1 =30+9+0.1

72.3 - 39.1 = 70+2+0.3 - (30+9+0.1)

72.3 - 39.1 = 70+2+0.3 - 30-9-0.1

72.3 - 39.1  = 70-30+2-9+0.3-0.1

72.3 - 39.1 = 40 - 7 +0.2

72.3 - 39.1 = 4tens - 7ones + 2tenth

Answer:

120.00

Step-by-step explanation:

Let x be the original price

The price is 10% off, or we pay 90% of the original price

.9 x

Then we have to pay 7% sales tax

.9x * 7%

.9x * .07

.063x is the tax

Add this to the .9x we have to pay for the jacket

.9x + .063x = .963x

This is the cost of the jacket

.963x = 115.56

Divide each side by.963

.963x/.963 = 115.56/.963

x =120.00

For any price of h and k = -12, the system x + 3y = h and -4x + ky = -9 will haven't any answer.

To determine the values of h and okay for which the device of equations has no answer, we want to locate the situations underneath which the equations are inconsistent or parallel.

The given system of equations is:

Equation 1: x + 3y = h

Equation 2: -4x + ky = -9

For the gadget to haven't any answer, the lines represented with the aid of these equations should be parallel and in no way intersect. In different phrases, the slopes of the traces need to be equal, but the y-intercepts should be specific.

Let's first discover the slopes of the traces. The slope-intercept form of Equation 1 is y = (-1/3)x + (h/3), wherein the slope is -1/3. The slope-intercept shape of Equation 2 is y = (4/k)x - (9/k), wherein the slope is 4/k.

For the strains to be parallel, the slopes should be equal. Therefore, we have the condition: -1/3 = 4/k.

To locate the values of h and okay for which the gadget has no answer, we need to locate the values of h that satisfy the situation -1/3 = 4/k.

Solving this equation for ok, we've got:

-1/3 = 4/k

-1 = 12/k

k = -12

Substituting k = -12 returned into the equation -1/3 = 4/k, we've:

-1/3 = 4/(-12)

-1/3 = -1/3

Since the equation holds real for any value of h, there aren't any restrictions at the price of h.

Therefore, for any price of h and k = -12, the system x + 3y = h and -4x + ky = -9 will haven't any answer.

The system of equations has no solution when k is equal to 12. The value of h can be any real number.

To determine the values of h and f for which the system has no solution, we need to analyze the coefficients of the variables and the constants in the equations.

The given system of equations is:

x + 3y = h

-4x + ky = -9

We can rewrite the second equation as:

-4x + ky = -9

Dividing both sides of the equation by -4, we get:

x - (k/4)y = 9/4

Comparing the coefficients of x and y in the two equations, we can see that the slopes of the lines represented by the equations are different when k is not equal to 12.

Therefore, for the system to have no solution, k must be equal to 12.

As for the value of h, it can be any real number since it does not affect the slopes of the lines.

As per the question statement, no information about the vegetables Gorgio used for his dinner or their prices are provided in the question statement, and thus we are considering that, Gorgio used 3 bell peppers that costed $2.05, 4 tomatoes at $1.09, 2 onions at $0.65 and 5 potatoes at $0.33 in his dinner recipe.

We are required to calculate how much does Gorgio's dinner meal cost.

In 2 years, Ari will need to pay off the loan.

Simple interest is the borrowing amount added only to the principal amount.

The formula to calculate the simple interest is;

                                                 S.I. = P x T x R / 100 ,

Where S.I. is simple interest , P is principal amount, T is time period and R is interest rate in a year.

Given:

Greg lends Ari $125 at an annual interest rate of 10%.

And Ari wants to pay no more than $25.00 in simple interest.

To find the time period:

Use simple interest rate formula:

A = P x R x T / 100

We have,

P = $125, R = 10, A = $25.00

Substituting all the values to the formula,

25 = 125 x 10 x T / 100

T = 25 x 100 / 1250

T = 2500 / 1250

T = 2 years.

Therefore, 2 years is the time period for the loan amount.

When the price is $22, the rate of change in sales volume is roughly -0.014 (thousands of units per dollar). This suggests that the sales volume is likely to decline by 0 units for every $1 rise in price, demonstrating a negligible impact of price on volume.

To find the rate of change in sales volume when the price is $22, we need to calculate the derivative of the sales volume function with respect to the price and evaluate it at the given price.

The sales volume function is given by:

\(y = \frac{32}{{(3p + 1)}^{-\frac{2}{5}}}\)

To find the derivative, we can use the chain rule. Let's denote the derivative as \(\frac{dy}{dp}\):

\(\frac{dy}{dp} = \left(-\frac{2}{5}\right) \cdot 32 \cdot (3p + 1)^{-\frac{2}{5} - 1} \cdot (3)\)

Simplifying the expression, we have:

\(\frac{{dy}}{{dp}} = \frac{{-64}}{{5 \cdot (3p + 1)^{\frac{{7}}{{5}}}}}\)

Now, we can evaluate the derivative at the price p = $22:

\(\frac{{dy}}{{dp}} = \frac{{-64}}{{5 \cdot (3 \cdot 22 + 1)^{\frac{{7}}{{5}}}}}\)

\(= \frac{{-64}}{{5 \cdot (66 + 1)^{\frac{{7}}{{5}}}}}\)

\(= \frac{{-64}}{{5 \cdot (67)^{\frac{{7}}{{5}}}}}\)

Calculating this expression to three decimal places, we get:

\(\frac{{dy}}{{dp}}\) ≈ -0.014

(a) The rate of change in sales volume when the price is $22 is approximately -0.014 (thousands of units per dollar).

(b) Interpretation: If the price increases by $1, the sales volume will decrease by approximately 0.014 (thousands of units). Rounded to the nearest whole number, we can say that the sales volume will decrease by 0 units. This suggests that a small increase in price has negligible impact on the sales volume.
