The profit Haddie makes from selling scarves at a craft fair can be represented by the algebraic expression P = 12s - 25. Here, P represents profit, s represents the number of scarves sold, 12 represents the price of each scarf, and 25 represents the cost of booth rental.

The subject of the question deals with the concept of profit in a business transaction, which falls under Mathematics, specifically algebra and economics. It's a High School level problem since it involves creating a basic algebraic expression.

Haddie's profit can be determined by subtracting her costs (the booth fee) from her earnings (the sale of the scarves). She earns $12 for each scarf sold, represented as 12s (where s is the number of scarves sold), and she has a fixed cost of $25 for the booth rental.

Therefore, the expression for Haddie's profit, P, for selling s scarves is: P = 12s - 25. This expression represents the total amount Haddie will earn from selling s scarves after deducting her cost for the booth rental.

Answer: -5 1/2

Step-by-step explanation:

The answer is implicit

Answer:

Implicit Differentiation is necessary in order to find derivatives of curves that do not represent a function because the functions cannot be simplified to a simple function. Using dy/dx and implicit differentiation can be used to find the derivative with respect to one variable and determine the affect each variable has on one another and calculate the rate of change of the variables over time. Differentiating both x and y in Implicit Differentiation makes it so that complex functions are much easier and instead of solving for one variable, differentiating one variable to the other is an easier method. My implicit function is 2y^2-x^2+x^3y=2. First Derivative= -3yx^2+2x/4y+x^3 Second Derivative= 3yx^4-4y^3-24y^2x+8y/(4y+x^3)^2 Third Derivative = 6y(-x^6+28yx^3+4y^2x^2-8x^2-16y)/(4y+x^3)^3

Answer:

1 liter × 0.2642 gallons liter × 33.817 fluid ounces gallon.

Step-by-step explanation:

Given:

1 gallon = 3.785 liters

We need to find how many fluid of ounce are there in 1 liter.

First we will find number of gallons in 1 liter.

We know that;

3.785 liters = 1 gallons

1 liters = number of gallons in 1 liter.

By using Unitary method we get;

number of gallons in 1 liter = [tex]\frac{1}{3.785}= 0.2642\ gallons[/tex]

Now we know that:

1 gallons = 128 fluid ounce

So 0.2642 gallons = Number of fluid ounce in 0.2642 gallons

Again by using Unitary method we get;

Number of fluid ounce in 0.2642 gallons = [tex]128 \times 0.2642\approx 33.817\ oz[/tex]

Hence we can say,

1 liter ×0.2642 gallons liter × 33.817 fluid ounces gallon.

Answer:

see explanation

Step-by-step explanation:

Since the lines are parallel then

∠x  = 70° ( alternate angles are congruent )

Since the triangle is isosceles then the base angles are congruent, thus

∠y = ∠x = 70°

The sum of the angles in a triangle = 180°

Subtract the sum of x and y from 180 for z

∠z = 180° - (70 + 70)° = 180° - 140° = 40°

Hence ∠x = ∠y = 70° and ∠z = 40°

Answer:

[tex]y=\frac{5}{9}x+\frac{-83}{9}[/tex]

Step-by-step explanation:

Given equation of line:

[tex]9x+5y=3[/tex]

To find the equation of line perpendicular to the line of the given equation and passes through point (4,-7).

Writing the given equation of line in standard form.

Subtracting both sides by [tex]9x[/tex]

[tex]9x-9x+5y=3-9x[/tex]

[tex]5y=3-9x[/tex]  

Dividing both sides by 5.

[tex]\frac{5y}{5}=\frac{3}{5}-\frac{9x}{5}[/tex]  

[tex]y=\frac{3}{5}-\frac{9x}{5}[/tex]  

Rearranging the equation in standard form [tex]y=mx+b[/tex]

[tex]y=-\frac{9x}{5}+\frac{3}{5}[/tex]  

Applying slope relationship between perpendicular lines.

[tex]m_1=-\frac{1}{m_2}[/tex]

where [tex]m_1[/tex] and [tex]m_2[/tex] are slopes of perpendicular lines.

For the given equation in the form [tex]y=mx+b[/tex] the slope [tex]m_2[/tex]can be found by comparing [tex]y=-\frac{9x}{5}+\frac{3}{5}[/tex] with standard form.

∴ [tex]m_2=-\frac{9}{5}[/tex]

Thus slope of line perpendicular to this line [tex]m_1[/tex] would be given as:

[tex]m_1=-\frac{1}{-\frac{9}{5}}[/tex]

∴ [tex]m_1=\frac{5}{9}[/tex]

The line passes through point (4,-7)

Using point slope form:

[tex]y-y_1=m(x-x_1)[/tex]

Where [tex](x_1,y_1)\rightarrow (4,-7)[/tex] and [tex]m=m_1=\frac{5}{9}[/tex]

So,

[tex]y-(-7)=\frac{5}{9}(x-4)[/tex]

Using distribution.

[tex]y+7=(\frac{5}{9}x)-(\frac{5}{9}\times 4)[/tex]

[tex]y+7=\frac{5}{9}x-\frac{20}{9}[/tex]

Subtracting 7 to both sides.

[tex]y+7-7=\frac{5}{9}x-\frac{20}{9}-7[/tex]

Taking LCD to subtract fractions

[tex]y=\frac{5}{9}x-\frac{20}{9}-\frac{63}{9}[/tex]

[tex]y=\frac{5}{9}x+\frac{(-20-63)}{9}[/tex]

[tex]y=\frac{5}{9}x+\frac{-83}{9}[/tex]

[tex]y=\frac{5}{9}x-\frac{83}{9}[/tex]

Thus, the equation of line in standard form is given by:

[tex]y=\frac{5}{9}x-\frac{83}{9}[/tex]

Final answer:

The correct phrase to complete the sentence is 'A. Will have gone' since it requires the future perfect tense to indicate that nine years will have passed after the upcoming summer.

Explanation:

The correct phrase to complete the sentence "After this summer we __ for nine years straight." is A. Will have gone. This is because the sentence is referring to a future event where the duration of nine years will have been completed after this coming summer, which requires the future perfect tense. The future perfect tense is formed with 'will have' followed by the past participle of the verb, which in the case of 'go' is 'gone'.

Answer:

801-792

Step-by-step explanation:

I got my answer by picking out a big number first (801) and subtracting it by another big number (701) to get an answer less than 100.

To form a subtraction equation with two three-digit numbers having different hundreds digits and a difference of less than 100, choose numbers where the hundreds digits are one number apart and the tens and ones digits are close, such as 756 - 657 = 99.

To write a subtraction equation that involves two three-digit numbers with different hundreds digits and a difference of less than 100, we need to select numbers where the hundreds digit is only 1 apart and the tens and ones digits are close. For example, the numbers 654 and 756. Subtracting these gives us:

756 - 654 = 102

We notice the result is slightly over 100. Therefore, we can adjust the tens or ones digits to reduce the difference. If we change 654 to 657, then:

756 - 657 = 99

In this case, we achieved a result that is less than 100. It's important to note that, in subtraction, we change the sign of the subtracted number before operating the addition as per standard arithmetic rules.

Answer:

a=0.41

Step-by-step explanation:

7(a-10)=13-202a+3

7a-70=13+3-202a

7a-(-202a)-70=16

7a+202a=16+70

209a=86

a=86/209

a=0.41

To solve the equation 7(a - 10) = 13 - 202a + 3, begin by simplifying both sides of the equation and combining like terms. Then isolate the variable 'a' to one side and the constant terms to the other. Finally, divide both sides by the coefficient of 'a' to solve for 'a'.

To solve the equation 7(a - 10) = 13 - 202a + 3, you can start by simplifying both sides of the equation. Expand the terms on the left side by distributing the 7 to the terms inside the parentheses. Combine like terms on both sides of the equation. Then, isolate the variable by moving all the terms with 'a' to one side of the equation and all the constant terms to the other side. Finally, divide both sides of the equation by the coefficient of 'a' to solve for 'a'.

4x > 36-4

4x > 32 (divide both sides of the inequality by 4 )

4x ÷ 4 > 32 ÷ 4

x > 8

Final answer:

To determine the solution set of the inequality 4x + 4 > 36, subtract 4 from both sides to get 4x > 32 and then divide by 4 to find x > 8. Any number greater than 8 is part of the solution set.

Explanation:

To find which number is in the solution set of the inequality 4x + 4 > 36, we need to solve for x by performing a series of steps:

Subtract 4 from both sides of the inequality to get 4x > 32.

Divide both sides of the inequality by 4 to solve for x, resulting in x > 8.

Thus, any number greater than 8 is in the solution set of the given inequality.

Answer:

f(x) = x³ + x² - 5x + 3

Step-by-step explanation:

The cubic polynomial has zeros at 1, 1, - 3.

Therefore, x = 1, 1, - 3 are the roots of the polynomial and hence, (x - 1), (x - 1) and (x + 3) will be factors of the cubic polynomial.

Hence, we can write the polynomial as a function of x as

f(x) = (x - 1)(x - 1)(x + 3)

⇒ f(x) = (x² - 2x + 1)(x + 3)

⇒ f(x) = x³ - 2x² + 3x² + x - 6x + 3

⇒ f(x) = x³ + x² - 5x + 3

So, this is the cubic polynomial function in standard form. (Answer)

The amount at end of 1 year is $ 109.2025

Solution:

Given that,

Principal = $ 100

Rate of interest = 9 % compounded semiannually

Number of years = 1

The formula for total amount using compounded semiannually is:

[tex]A=p\left(1+\frac{r}{n}\right)^{n t}[/tex]

A = the future value of the investment/loan, including interest

P = the principal investment amount (the initial deposit or loan amount)

r = the annual interest rate (decimal)

n = the number of times that interest is compounded per unit t

t = the time the money is invested or borrowed for

Here, [tex]r = 9 \% = \frac{9}{100} = 0.09[/tex]

Here, n = 2 since interest is compounded semiannually

Substituting the values in formula,

[tex]A=100\left(1+\frac{0.09}{2}\right)^{2 \times 1}[/tex]

[tex]\begin{aligned}&A=100(1+0.045)^{2}\\\\&A=100(1.045)^{2}\\\\&A=100 \times 1.092025=109.2025\end{aligned}[/tex]
