Step-by-step explanation:

Capital assets are significant pieces of property such as homes, cars, investment properties, stocks, bonds, and collectibles or art. For businesses, a capital asset is an asset with a useful life longer than a year that is not intended for sale in the regular course of the business's operation.

The capital asset is recorded as its value regardless of any loan that may have been used to purchase it.

Capital assets here are: Home value, work equipment, car, and investments.

All other items are liabilliabilities.

The total value of the doctor's capital assets will be $647,574. Then the correct option is D.

Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.

Significant pieces of property including houses, automobiles, rental properties, stocks, bonds, and collectibles or works of art are referred to as capital assets. An asset having a useful life longer than a year that is not intended for sale during normal company operations is referred to as a capital asset for enterprises.

The assets and liabilities of a doctor are listed below.

Home Value                         $475,732

Mortgage                              $105,678

Credit Card Balance             $7,264

Investments                          $75,283

Personal Loan                      $32,187

The total value of the doctor's capital assets will be given as,

⇒ $475,732 + $45,798 + $50,761 + $75,283

⇒ $647,574

The total value of the doctor's capital assets will be $647,574. Then the correct option is D.

Answer:

Step-by-step explanation:

You want a system of equations and a graphical solution for the scenario that the weight of peaches sold (y) is 3 times the weight of apples sold (x), and the revenue from sales of apples at $3/lb and peaches at $4/lb was a total of $240.

The revenue equation can be ...

  3x +4y = 240

The relation between pounds of each fruit sold can be ...

  y = 3x

The graph is attached. The solution is (x, y) = (16, 48).

16 pounds of apples and 48 pounds of peaches were sold.

__

Additional comment

We note that the 3x in the first equation can be substituted by y using the second equation. This gives 5y=240, or y = 48. Then 3x=48, so x=16. This agrees with the graphical solution, as it should.

Answer:

To find the equivalent of 2 4/5 + 4/6, we first need to convert the mixed numbers to improper fractions. To do this, we multiply the whole number part of the mixed number by the denominator of the fraction part, and add the result to the numerator of the fraction part. So 2 4/5 becomes 2 * 5 + 4 = 14/5. Similarly, 4/6 becomes 4 * 1 + 6 = 10/6.

Next, we need to find a common denominator for the two fractions so that we can add them. A common denominator for 14/5 and 10/6 is 30, so we convert both fractions to have a denominator of 30. To convert 14/5 to have a denominator of 30, we multiply the numerator and denominator by 6, which gives us 14 * 6 / 5 * 6 = 84/30. Similarly, we multiply the numerator and denominator of 10/6 by 5 to get 10 * 5 / 6 * 5 = 50/30.

Now that both fractions have a denominator of 30, we can add them to get the equivalent of 2 4/5 + 4/6. This gives us 84/30 + 50/30 = 134/30. Finally, we simplify the fraction to get the final answer, which is 134/30 = 4 8/30 = 4 4/15. So, the equivalent of 2 4/5 + 4/6 is 4 4/15.

1 7/19

Step-by-step explanation:

First, to solve this problem, you change the mixed fraction to improper fractions:

13/3 / 19/6

Now, you make it into a multiplication problem by multiplying the first number by the reciprocal of the second number.

13/3 x 6/19

Simplify :

13/1 x 2/19

Multiply the numerators by denominators to get the total:

26/19 or simplified: 1 7/19

Cost of shrub is $4 and Cost of hosta is $3. Cost is the value of money that was spent on producing or providing a service and is therefore no longer available for use.

The term "cost" can refer to the amount of money or other resources that are required to produce, acquire, or obtain something. In business and economics, cost is often used to refer to the total expense associated with a product or service, including materials, labor, and other expenses.

Micaela spent a total of $33 on 3 hostas and 6 shrubs. Since the cost of the hostas is H x 3 and the cost of the shrubs is S x 6, we can write the following equation:

H * 3 + S * 6 = 33

Similarly, Sumalee spent a total of $42 on 6 hostas and 6 shrubs, so we can write the following equation:

H * 6 + S * 6 = 42

cost 3 hostas and 6 shrubs = $33

cost 6 hostas and 6 shrubs = $42

Cost difference 33 - 42 = 9

So, cost of 3 hostas = $9

Cost of one hosta = $9/3 = $3

$9 + cost of 6 shrubs = $33

cost of 6 shrubs = $33- $9 = $24

Cost of one shrub = $24/6 = $4

Cost of shrub is $4 and Cost of hosta is $3.

The actual average score on the vocabulary test is 91.8.

A percentage is a value or ratio that may be stated as a fraction of 100. If we need to calculate a percentage of a number, we should divide it's entirety and then multiply it by 100.

Here, Mr. Johnson predicted the average score on the vocabulary test he gave would be 85 points and his prediction was 8% lower than the actual average score.

The actual score will be:

Answer:

This is a problem of weighted averages and can be solved with a system of equations.

Let's define:

- `x` as the amount (in lbs) of the cheaper chocolate,

- `y` as the amount (in lbs) of the expensive chocolate.

We can set up the following equations:

1. `x + y = 62.4` (the total amount of chocolate we want)

2. `$2.10x + $9.90y = $2.40 * 62.4` (the total cost of the chocolate mixture)

The second equation represents the total value of the chocolate, while the first represents the total weight.

We can solve this system of equations using substitution or elimination. In this case, it may be simpler to use elimination.

Let's first transform the second equation to get rid of the dollar signs:

2.10x + 9.90y = 2.40 * 62.4

2.10x + 9.90y = 149.76

Let's now multiply the first equation by 2.10 (the price per lb of the cheaper chocolate):

2.10x + 2.10y = 2.10 * 62.4

2.10x + 2.10y = 131.04

Subtracting the second equation (multiplied) from the original second equation, we get:

9.90y - 2.10y = 149.76 - 131.04

7.80y = 18.72

Solving for y, we get:

y = 18.72 / 7.80 = 2.4 lbs

Substituting y = 2.4 into the first equation:

x + 2.4 = 62.4

x = 62.4 - 2.4 = 60 lbs

So, you will need 60 lbs of the cheaper chocolate and 2.4 lbs of the expensive chocolate to obtain the desired mixture.

The measures of two angles in the order from the smallest to the greatest are 21° and 69°.

What is a right triangle?

A right triangle, also known as a right-angled triangle, right-perpendicular triangle, orthogonal triangle, or formerly rectangle triangle, is a triangle with one right angle, or two perpendicular sides. The foundation of trigonometry is the relationship between the sides and various angles of the right triangle.

Given the acute angle of a right triangle is 6 more than 3 times the measure of the other small angle.

Assume that the measurement of smaller angle is x.

Then the mathematical expression of 6 more than 3 times of x is 6 + 3x.

The measure of third angle is 90° since it a right triangle.

The sum of all interior angles of a right triangle is 180°.

The equation is

x + (6 + 3x) + 90 =180

x + 6 + 3x + 90 =180

Combine like terms:

(x + 3x) + (6 + 90) = 180

4x + 96 = 180

Subtract 96 from both sides:

4x = 180 - 96

4x = 84

Divide both sides by 4

x = 21

Putting x = 21 in the expression (6 + 3x) :

6 + 3x = 6 + 63 = 69.
