UGRENT 8TH GRADE MATH QUESTION! Write the equation 4x + 2y - 6 = 0 in the slope-intercept form (y = mx + b).

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:

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.

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:

[tex]\sqrt{-5}=i\sqrt{5}[/tex]

[tex]\sqrt{-25}=5i[/tex]

Step-by-step explanation:

i is an imaginary unit, this means

[tex]i^2=-1[/tex]

Rewrite -5 as [tex]5\cdot (-1)=5\cdot i^2,[/tex]

then

[tex]\sqrt{-5}=\sqrt{5i^2}=\sqrt{5}\cdot \sqrt{i^2}=\sqrt{5}\cdot i=i\sqrt{5}[/tex]

Rewrite -25 as [tex]-25=25\cdot (-1)=25\cdot i^2,[/tex]

then

[tex]\sqrt{-25}=\sqrt{25\cdot i^2}=\sqrt{25}\cdot \sqrt{i^2}=5\cdot i=5i[/tex]

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]

Thus the amount at end of 1 year is $ 109.2025

Answer: -5 1/2

Step-by-step explanation:

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'.

Answer:

Step-by-step explanation: the answer is A beacause the sentence is in the past tense and answer A is the only one that would be gramatically correct

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:

[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]

Length and width of book is 5.91 inches and 2.36 inches respectively

Solution:

Given that a book is 15 centimeters long and 6 centimeters wide

To find: length and width of book in inches

From given question,

Length of book = 15 cm

Width of book = 6 cm

The conversion factor used is:

1 cm = 0.393701 inches

Therefore, length of book in inches is:

[tex]15 \text{ cm} = 15 \times 0.393701 \text{ inches }= 5.905515 \text{ inches }[/tex]

Rounding off rules:

First look at the digit to immediate right of rounding off digit

If that digit is less than 5, do not change the rounding digit but drop all digits to the right of it.

If that digit is greater than or equal to five, add one to the rounding digit and drop all digits to the right of it.

On rounding to nearest hundredth, ( two decimal places )

[tex]5.905515 \text{ inches } = 5.91 \text{ inches }[/tex]

Width of book in inches:

[tex]6 \text{ cm} = 6 \times 0.393701 \text{ inches } = 2.362206 \text{ inches }[/tex]

On rounding to nearest hundredth, we get 2.36 inches

Final answer:

The book measures approximately 5.91 inches in length and 2.36 inches in width.

Explanation:

To convert the dimensions of the book from centimeters to inches, we use the conversion factor that 1 inch is equal to 2.54 centimeters.

The length of the book in inches is calculated as follows:

Similarly, the width of the book in inches is:

Therefore, the book measures approximately 5.91 inches in length and 2.36 inches in width.

Step-by-step explanation: Because you have to add the first 7

Jerome has paid a total of [tex]\$195.54[/tex]rest over the 7 months.

To find the total amount that Jerome has paid in interest over the 7 months, we need to sum up the interest paid each month. The interest for each month is calculated as follows:

[tex]\[ \text{Interest for the month} = \text{Previous balance} \times \text{APR} / 12 \][/tex]

Let's calculate the interest for each month:

1. For the second month:

 [tex]\[ \text{Interest} = \$2200.00 \times 0.18 / 12 = \$33.00 \][/tex]

2. For the third month:

[tex]\[ \text{Interest} = \$2189.00 \times 0.18 / 12 = \$32.84 \][/tex]

3. For the fourth month:

[tex]\[ \text{Interest} = \$2178.06 \times 0.18 / 12 = \$32.67 \][/tex]

4. For the fifth month:

[tex]\[ \text{Interest} = \$2167.16 \times 0.18 / 12 = \$32.51 \][/tex]

5. For the sixth month:

[tex]\[ \text{Interest} = \$2156.33 \times 0.18 / 12 = \$32.34 \][/tex]

6. For the seventh month:

 [tex]\[ \text{Interest} = \$2145.55 \times 0.18 / 12 = \$32.18 \][/tex]

Now, sum up these monthly interest amounts:

[tex]\[ \$33.00 + \$32.84 + \$32.67 + \$32.51 + \$32.34 + \$32.18 = \$195.54 \][/tex]

So, Jerome has paid a total of [tex]\$195.54[/tex]rest over the 7 months.

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:

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°

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.

Should college be free? It’s a classic question with a complicated and arguably unclear answer. The affordability of college education, as well as the current student debt crisis, is always one of the center-stage issues for presidential political seasons. In fact, many candidates build their platforms around college costs as a key issue.

As with any major decision, especially relating to higher education, there are pros and cons to consider. Let me help break down the positives and negatives of tuition-free college.

The PROS of Tuition-Free College

More Lower-Income Students Might Reach Graduation if There’s No Tuition

Some students drop out because they do not have the ability to pay for tuition all four years. Getting rid of tuition would eliminate this reason for not graduating. This would also serve to improve college graduation rates, as fewer students would feel the need to drop to part-time status or take a break from education for financial reasons.

Student Debt Will No Longer Crush the Younger Generations

If an American college student is able to graduate with less than $10,000 in student loan debt, they are considered lucky (the average is $37,000). However, students from other countries that don’t have tuition already have that luxury; most of their loans come from living expenses and books. Without the weight of student loan debt, more college graduates might buy houses rather than renting apartments. They might buy cars, spend more on healthy food, travel more: In essence, they could contribute more to the economy.

Students Might Have More Freedom to Choose a Major They Enjoy

Whether it is the influence of parents or knowing you need to pay loans back as quickly as possible, current students are often guided toward “practical” majors that have a more lucrative post-graduation income. If shelling out thousands upon thousands of dollars is no longer a factor, parents and students might feel more relaxed about studying for majors that don’t necessarily have a large paycheck associated with them. Interest and enjoyment from a field of study goes a long way in helping students stick with it and avoid burning out.

More People Would Go to College

By negating the large bill of a college education, we could see an increase in the number of students able to attend college. This then creates a more well-educated workforce and a population that has better critical thinking skills. This could lead to more innovation in all areas of society. This would also help people with financial need to earn an education
