Answer 26550

Step-by-step explanation:

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: 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:

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

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:

l^3 - 10l^2 + 24l - 576 = 0

This is a cubic equation, and finding the exact value for l can be difficult. However, we can use numerical methods, such as the bisection method or Newton's method, to find an approximate value.

Step-by-step explanation:

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 cost of a 15-minute call to this city would be $2.00.

The cost of a long-distance call to a certain city is typically $1.05 for the first minute and $0.15 for each additional minute or part thereof. This means that for each minute of the call, you will be charged $0.15 in addition to the first minute's charge. Therefore, for a 15-minute call to this city, you will be charged $1.05 for the first minute and 14 x $0.15 for the additional minutes, which comes to a total of $2.00. This price may vary depending on the phone carrier, but it is typically the same across the board.

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:

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.

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

Therefore, 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.

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

The proportion of current smokers among the 1685 high school students surveyed is 437/1685 = 0.259 or 26%.

b. What is the point estimate for the population proportion of all high school students who smoke?

The point estimate for the population proportion of all high school students who smoke is 0.259.

c. What is the 95% confidence interval for the population proportion of all high school students who smoke?

The 95% confidence interval can be calculated using the formula:

point estimate ± 1.96 * standard error

where standard error = square root of (point estimate * (1 - point estimate) / sample size)

standard error = square root of (0.259 * (1 - 0.259) / 1685) = 0.012

95% confidence interval = 0.259 ± 1.96 * 0.012

= 0.259 ± 0.023

= [0.236, 0.282]

So, the 95% confidence interval for the population proportion of all high school students who smoke is between 23.6% and 28.2%.

If negative sixteen plus the quotient of a number and 2 is 35, the number is 102.

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

Number = x

Negative sixteen plus the quotient of a number and 2 is 35.

This can be written as,

Quotient of a number and 2.

x ÷ 2 = M (quotient)

So,

-16 + M = 35

Now,

Solve for M.

M = 35 + 16

M = 51

Now,

x ÷ 2 = 51

x/2 = 51

x = 51 x 2

x = 102

Now,
