If Hank bought a 4 room home for a rental, and he put 20% down on the $300,00. 00 rental unit, the annual depreciation amount would be $8,727.27 .

To determine the depreciation amount, we first need to determine the depreciable basis of the rental property. The depreciable basis is the portion of the property's value that can be depreciated over time.

In this case, Hank put 20% down on a $300,000 rental unit, which means he paid $60,000 as a down payment. Therefore, the depreciable basis of the rental property is the remaining $240,000 ($300,000 - $60,000).

The IRS allows rental property owners to depreciate the depreciable basis of their property over 27.5 years using the straight-line method. To calculate the annual depreciation amount, we divide the depreciable basis by the number of years of useful life.

So, in this case, the annual depreciation amount would be $8,727.27 ($240,000 / 27.5). This means that Hank would be able to deduct $8,727.27 from his rental income each year for 27.5 years to account for the wear and tear of the property.

The two resulting equations are set equal to one another and solved for the values of the variables. Therefore, the solution to the system of equations is x = 3 and y = -45.

The equal values method is a way of solving systems of equations. It involves isolating each variable on its own side of the equation and then setting the two equations equal to one another. This results in an equation with only one variable, which can then be solved. For example, the system of equations given is -8x - 21 = 6x + 7. To solve this system with the equal values method, one must first isolate the variables. The first equation can be rearranged to -8x = 21 + 6x, and then solved for x to find x = 3. Then, the same value of x can be substituted into either of the original equations to solve for y. For example, substituting x = 3 into the first equation gives -8(3) - 21 = -24 - 21 = -45, so y = -45. Therefore, the solution to the system of equations is x = 3 and y = -45.

Answer:

103.42

Step-by-step explanation:

use the big circle area - 2 little white circles' area

big r = 12.5/2 = 6.25 so big circe area = π r² =π * 6.25²

small r = 3.5/2 = 1.75 so small circe area = π r² =π * 1.75²

2 of them = 2π * 1.75²

so π 6.25² - 2π * 1.75² = 39.06π-6.13π=103.42

well, looking at the picture above, we can see that the diameters are 12.5 and 3.5 for those circles, that means the radii for them will be half that for each, namely 6.25 and 1.75 respectively.

Answer:

Step-by-step explanation:

The volume of a cylinder with height "h" and radius "r" is given by the formula: V = πr^2h.

The volume of a cone with height "h" and radius "r" is given by the formula: V = (1/3)πr^2h.

To find the volume of a cone with the same height and radius as a cylinder with a volume of 234 cubic inches, we need to find the height and radius of the cylinder. We can use the volume formula for the cylinder to do this:

V = πr^2h

234 = πr^2h

Dividing both sides by πr^2:

h = 234 / (πr^2)

Now that we know the height, we can use it to find the radius using the volume formula for the cylinder:

234 = πr^2h

Taking the square root of both sides:

r = √(234 / πh)

Finally, we can use the height and radius to find the volume of the cone:

V = (1/3)πr^2h

This answer will give us the volume of a cone with the same height and radius as a cylinder with volume 234 cubic inches.

The sign of the expression is positive, since the result is positive.

An algebraic expression is a mathematical phrase that can contain numbers, variables, and operations. Algebraic expressions are used to represent mathematical relationships and can be simplified, evaluated, and solved for particular values of the variables.

Algebraic expressions can be simple, such as a single variable or number, or complex, involving multiple variables, operations, and grouping symbols, such as parentheses. For example, the expression "x + 2" is a simple algebraic expression, where "x" is the variable and "2" is the constant term.

In algebra, variables are used to represent unknown values and the goal is often to find the value of these variables that satisfy a given condition or equation. Algebraic expressions can be simplified by combining like terms and applying the properties of arithmetic operations.

Algebraic expressions are also used to represent mathematical functions. A function is a relationship between an input value and an output value, where each input value corresponds to exactly one output value. Algebraic expressions can be used to define a function, and can also be used to find the value of the function for a particular input.

The expression 39 11 13​ +(−41 131​ )39, 11/13 + (−41/13) simplifies to 39 11 13​ +(−41 131​ )39, 11/13 + (−41/13) = 39 11 13 - 41 131​ = (39 × 13 - 41 × 11) / 13 = (507 - 451) / 13 = 56 / 13 = 4.

The amount Micah withdrew can be represented as a rational number as 4.5 or 9/2.

A rational number is a number that can be expressed as the ratio of two integers. In this situation, we can represent the amount Micah withdrew as a rational number by expressing it as a fraction.

To do this, we can treat the dollar amount as a whole number (i.e. 4 dollars), and the cents amount as another whole number (i.e. 50 cents), and then express the total amount as a fraction with the sum of these two whole numbers as the numerator and 100 as the denominator (since there are 100 cents in a dollar).

So, the rational number representation of Micah's withdrawal would be:

Answer: Let's call the length of the brick "l". Then, the width is "l - 4" and the height is "l - 6".

The volume of the brick can be expressed as:

Since each mold holds 576 cubic inches of mud, we can set the volume of the brick equal to 576 and solve for l:

l * (l - 4) * (l - 6) = 576

Expanding and simplifying the left side of the equation, we get:

Where the above condition exists, the probability that the lawn mower will not start on the first try exactly once out of the next two times you mow the lawn is 5/18, or approximately 0.278.

We can calculate the probability that the lawn mower will not start on the first try exactly once out of the two rounds using a binomial probability distribution.

Let's define a success as the lawn mower starting on the first try, and a failure as the lawn mower not starting on the first try.

The probability of a success is p = 5/6, since the lawn mower does not start on the first try 1/6 of the time.

The probability of a failure is q = 1/6.

The probability of getting exactly one failure out of two trials can be calculated using the binomial probability formula:

P(X = 1) = (2 choose 1) * (5/6)^1 * (1/6)^1

where (2 choose 1) is the number of ways to choose one failure out of two trials.

Simplifying this formula, we get:

P(X = 1) = 2 * 5/6 * 1/6

P(X = 1) = 5/18
