editing) and variable costs (such as printing). The one-time fixed costs will total $32,060. The variable costs will be $12.75 per
book. The publisher will sell the finished product to bookstores at a price of $21.50 per book. How many books must the
publisher produce and sell so that the production costs will equal the money from sales?

Answer:

No

Step-by-step explanation:

like terms are terms which have the same variable , that is

10x and - 5x are like terms, they both have the same variable x

From the calculation carried out below, it can be observed that the profit for 77 sales is $258.

Given revenue as:

f(x) = 5x ............................ (1)

Where:

x = Number of bracelets sold or sales = 77

Total obtain the revenue, substitute x = 77 into equation (1), we have:

Revenue = f(77) = 5 * 77

Revenue = $385

Since profit is $50 less than 80% of the revenue, we have:

Profit = (Revenue * 80%) - 50

Profit = (385 * 80%) - 50

Profit = 308 - 50

Profit = $258

The variance of their​ weights is 128.87270 kg².

It is required to find the variance of their​ weights.

A standard deviation (or σ) is a measure of how dispersed the data is in relation to the mean. Low standard deviation means data are clustered around the mean, and high standard deviation indicates data are more spread out.

Given:

Let n=sample size=10 subjects

Standard deviation=11.352211.3522 kg

Using this formula

Variance=(Standard deviation)²

By the formula we get,

Variance=(11.352211.3522 kg)²

Variance=128.87270 kg²

Therefore, the variance of their​ weights is 128.87270 kg².

Step-by-step explanation:

The property which justifies the statement, ∠LMN ≅ ∠LMN is: C. reflexive property of ≅.

In Mathematics, two geometric figures are considered to be congruent only when their corresponding side lengths are congruent and the magnitude of their angles are congruent.

The reflexive property of congruence states that a line segment, an angle, or geometric shape (geometric figure) is always congruent to itself.

This ultimately implies that, for all angles M , ∠M ≅ ∠M. In this context, we can reasonably infer and logically deduce that the property which justifies the statement, ∠LMN ≅ ∠LMN is reflexive property of ≅.

The value of the exponent equation [tex]\frac{8}{125} ^{-2/3}[/tex] is 25/4 or 6.25.

According to the question the exponent equation that we have been given is :

          [tex]\frac{8}{125} ^{-2/3}[/tex]

First, we will change the negative sign of the exponent and to change the negative sign of the exponent we will reciprocal the fraction that is

        = [tex]\frac{125}{8} ^{2/3}[/tex]

Which is also equal to

  =   [tex]{125} ^{-2/3}/8^{2/3}[/tex]

Now we know that 5³ =125 and 2³ = 8. Thus replacing the numerator and denominator by it we get,

  =  [tex](5^{3}) ^{2/3}/(2^{3}) ^{2/3}[/tex]

  =  5²/2²

  = 25/4

  = 6.25

Hence the value of the exponent equation is 25/4 or 6.25

Answer: square root of 5 and square root of  9

Step-by-step explanation:

Here is what the student wrote (re-pasting for clarity)

C = 1.9 x 9.95

C = 18.91

C = $18.91

The error happens in the 1st line

Why? Because the 1.9 should be 1.09

The 1.9 represents a tax of 90% when we want a 9% tax instead

In other words, 9% = 9/100 = 0.09 while 90% = 90/100 = 0.9

-----------------

This is what the steps should look like

C = 1.09 x 9.95

C = 10.8455

C = 10.85

Don't forget to round to the nearest hundredth, aka nearest penny.

The total cost, after sales tax, is $10.85

The evaluation of the expression is 2, if the expression is x - y + z(x + w).

Expressions are defined as mathematical statements that have a minimum of two terms containing variables or numbers.

Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions.

Given that x = 1, y = 1, w = 1, and z = 1

We have been given expression

⇒ x - y + z(x + w)

Substitute the values of x = 1, y = 1, w = 1, and z = 1 in the above expression,

⇒ 1 - 1 + 1(1 + 1)

⇒ 0 + 1(2)

⇒ 2

Hence, the evaluation of the expression is 2.

Hello, the answer is 194.04.

First, you would convert 140% to a decimal which is 1.4. Next, you would multiply 1.4 x 138.6 = 194.04.

So the steps to a percentage multiplied to a number are:

1. Convert the percentage to a decimal.

2. Multiply the decimal by the number.

3. You get the answer.

For the following equation of the line: y = (1/5)x + 1, y = (1/5)x + 5, y = 5x + 1, and y = 5x + 5, the line that is perpendicular to it and has the same y - intercept is: y = -5x + 1, y = -5x + 5, y = (-1/5)x + 1, and y = (-1/5)x + 5, respectively.

If two equations of the line are perpendicular with each other, then their slopes are negative reciprocal of one another.

To generate the equation of the line perpendicular to the given lines, with the same y-intercept,

1. Get the slope of each line and determine its y-intercept

2. Take the negative reciprocal of the slope and use it and the same y-intercept to get the equation.

y = (1/5)x + 1

slope = 1/5

y-intercept = 1

perpendicular line :

slope = -5

y-intercept = 1

equation : y = -5x + 1

y = (1/5)x + 5

slope = 1/5

y-intercept = 5

perpendicular line :

slope = -5

y-intercept = 5

equation : y = -5x + 5

y = 5x + 1

slope = 5

and

dV/dt = 3cm³/s   (volume rate as a function of time)

Let
