Answer:

I think 6.5 % tax.

Step-by-step explanation:

Answer:

Mary was charged a 6% tax

Step-by-step explanation:

To find the percentage tax Mary was charged, we need to determine the amount of tax she paid and then calculate that as a percentage of the original purchase price.

We know that the total bill after tax was $25.44, and the purchase price before tax was $24, so the tax paid must be:

$25.44 - $24 = $1.44

To find the percentage tax charged, we need to divide the tax paid by the original purchase price, then multiply by 100 to express the answer as a percentage:

($1.44 / $24) x 100% ≈ 6%

Therefore, Mary was charged a 6% tax.

Answer:

its 320

Step-by-step explanation:

The total number of many sixth-grade students at Luehrs Middle School found using the percentage is 320.

What is meant by percentage?

A value or ratio that may be stated as a fraction of 100 is referred to as a percentage in mathematics. If we need to calculate a percentage of a number, we should divide it by its entirety and then multiply it by 100. The proportion, therefore, refers to a component per hundred. Per 100 is what the word percent means. There is no dimension to percentages. As a result, it is known as a dimensionless number.

Given,

Number of students in sixth grade who has a pet dog = 112

The percentage of sixth grade students who has a pet dog = 35%

Let the number of total sixth grade students be x.

Percentage

= (Number of students with pet dog/Total number of sixth grade students *    100

35 = (112/x) * 100

35/100 = 112/x

x = (100/35) * 112 = 320

Therefore the total number of many sixth-grade students at Luehrs Middle School found using the percentage is 320.

A quart contains 32 ounces. This is true for both dry and liquid ounces.

In the United States, the conventional system of measurement—in which dry measurements are reported in weight ounces and volume measurements are given in fluid ounces—is frequently employed. Four cups, two pints, or 32 fluid ounces make up a quart.

It's crucial to keep in mind that the density of a component might affect how much an ounce weighs when weighing dry ingredients.

For instance, due to the difference in their densities, one fluid ounce of flour will weigh less than one fluid ounce of sugar. Nonetheless, regardless of the density, each fluid ounce has a standard weight when measuring volume using fluid ounces.

To find all real solutions of the equation 8x²3 - 27x²2 - 50x + 75 = 0, we can factor it by grouping

How to do that?

8x²3 - 27x²2 - 50x + 75 = 0

=> (8x²3 - 50x) - (27x²2 - 75) = 0

=> 2x(4x²2 - 25) - 3(9x²2 - 25) = 0

=> (2x - 3)(4x²2 - 9x + 15) = 0

Using the quadratic formula to solve the quadratic factor, we get:

4x²2 - 9x + 15 = 0

=> x = [9 ± sqrt(81 - 4(4)(15))] / (2(4))

=> x = [9 ± sqrt(-191)] / 8

Since the discriminant of the quadratic factor is negative, it has no real roots, and therefore, the only real solution of the equation is:

x = (2x - 3) = 0

=> x = 3/2

Therefore, the only real solution of the equation 8x²3 - 27x²2 - 50x + 75 = 0 is x = 3/2.

Volume of Cone B is 48 π³ units. We know both cones have same volume because we used the volume formula for cones to equate the volumes of the two cones.

To find the dimensions of Cone B, we need to use the formula for the volume of a cone, which is:

Volume=(1/3) × π × radius² × height

Since the volume of Cone A and Cone B are the same (48 π³ units), we can set up the following equation:

(1/3) × π × 6² × 4

=(1/3)× π × r² × h

Simplifying the equation, we get:

r² × h = 72

We can choose any values of r and h that satisfy this equation. For example, we could choose r = 4 units and h = 9 units. When we enter these numbers into the equation, we obtain:

4² × 9 = 72

This is a valid solution, as Cone B with radius 4 units and height 9 units would have a volume of: Volume = (1/3) × π × 4² × 9 = 48 π³ units

Therefore, Cone A and Cone B have the same volume of 48 π³ units, which we know because we used the volume formula for cones to equate the volumes of the two cones.

Answer:

x = -3

Step-by-step explanation:

A vertical line has an undefined slope and its equation can be written as x = a, where 'a' is the x-coordinate of any point lying on the line. This is because all points on a vertical line have the same x-coordinate.

In this case, we are looking for the equation of the vertical line that passes through the point (-3, 8). Since this line is vertical, its equation will be of the form x = a, where a is the x-coordinate of any point on the line.

We can see that the x-coordinate of the point (-3, 8) is -3, so the equation of the vertical line passing through this point will be:

x = -3

And that's the answer. The equation of the vertical line passing through the point (-3, 8) is x = -3.

The difference in the means is times the ranges. (19-9)/(24-7)=10/17 = 0.588235294, or slightly more than half a time the ranges of the two samples.

Height is the measure of vertical distance, either how "tall" something or someone is, or how "high" the point is. For example, a person's height is typically measured using a stadiometer and is recorded in centimeters or feet and inches. The height of a mountain is usually measured in meters or feet. In aviation, height is measured from the surface of the earth, either above ground level (AGL) or above mean sea level (AMSL).

This is the set of all real numbers except those between -8 and 4 (inclusive), since the absolute value of y+2 cannot be greater than 6 if y is between -8 and 4.

In mathematics, inequalities specify the connection between two non-equal values. Equal does not imply inequality. Typically, we use the "not equal symbol ()" to indicate that two values are not equivalent. But various inequalities are used to compare the values, whether it is less than or larger than.

First, we can simplify the left side of the inequality by distributing the absolute value:

8|y+2| - 3 > 45

8|y+2| > 48

Then, we can isolate the absolute value by dividing both sides by 8:

|y+2| > 6

This inequality means that $y+2$ must be either greater than 6 or less than -6:

$$ y+2 > 6 \text{ or } y+2 < -6 $$

Simplifying each of these inequalities, we get:

y > 4 or y < -8

1. The definition of cosigner of a loan is someone who will promise to pay the loan if the borrower doesn't.

2. She has made late payments which affects her character

3. The cosigner’s current financial situation

4. Capacity, collateral, character

5. The cosigner’s past record of paying on time.

6. They can't qualify for a loan by themselves.

7. The cosigner's financial assets, such as a house or car.

8.  They have a steady job.

9.  A person with a good credit history and a car and house.

1.

The correct definition of a cosigner for a loan is (c) someone who will promise to pay the loan if the borrower doesn't. A cosigner is a person who signs a loan document along with the primary borrower and assumes equal responsibility for the repayment of the loan.

2.

The answer is (d) she has made late payments which affects her character. When someone cosigns a loan, they become equally responsible for repaying the loan. This means that the lender will evaluate the cosigner's creditworthiness and ability to repay the loan just as they would with the primary borrower. The lender will look at factors such as the cosigner's credit score, debt-to-income ratio, and payment history to determine if they are a suitable cosigner.

3.

The correct definition of capacity for potential cosigners is (d) the cosigner's current financial situation. Capacity refers to a cosigner's ability to repay the loan if the primary borrower defaults. The lender will assess the cosigner's income, assets, and liabilities to determine if they have the ability to take on the additional debt.

4.

The correct answer is (a) Capacity, collateral, character. Lenders evaluate a borrower or cosigner's creditworthiness and ability to pay back a loan by analyzing their capacity to repay the loan, the collateral they can offer to secure the loan, and their character.

Capacity refers to the borrower's or cosigner's current financial situation, including their income, job stability, and current debts. Lenders look at this information to determine whether the borrower or cosigner can afford to make payments on the loan.

Collateral refers to assets that the borrower or cosigner can pledge as security for the loan. This could be a car, house, or other valuable property. Lenders use this information to assess the risk of the loan and the likelihood that they will be able to recover the funds if the borrower or cosigner defaults on the loan.

Character refers to the borrower or cosigner's reputation and willingness to repay the loan. Lenders will often check credit reports, payment histories, and references to determine whether the borrower or cosigner is reliable and trustworthy.

5.

The correct definition of character for potential cosigners is (a) the cosigner’s past record of paying on time. Character refers to the borrower or cosigner's creditworthiness and willingness to repay the loan. Lenders will often check the credit report, payment history, and references of the cosigner to determine whether they are reliable and trustworthy.

6.

The correct answer is (a) they can't qualify for a loan by themselves. A borrower may need a cosigner to secure a loan if they do not meet the lender's credit requirements. This could be due to factors such as a low credit score, insufficient income, or a high debt-to-income ratio. By having a cosigner with good credit and financial stability, the borrower can improve their chances of being approved for the loan.

7.

The correct definition of collateral for potential cosigners is (a) the cosigner's financial assets, such as a house or car. Collateral refers to assets that the borrower or cosigner can pledge as security for the loan. This could include a car, house, or other valuable property.

8.

The criteria that makes a person a good cosigner is (b) they have a steady job. A good cosigner should have a stable and consistent income, which shows the lender that they have the financial means to repay the loan if the borrower cannot. This can include a full-time job or other consistent source of income.

9.

The best choice for a cosigner for a car loan would be (b) a person with a good credit history and a car and house. A cosigner with a good credit history and established financial assets can provide additional security for the lender and increase the likelihood of the loan being approved. The presence of collateral, such as a car and house, can also help to secure a lower interest rate for the loan.

b) New area will be 25 square meters less than old area

Step-by-step explanation:

Lena' s square garden with side x has area x times x or x² square meters

If one side is lengthened by 5 meters that side becomes x + 5 meters

If the other side is shortened by 5 meters that side becomes x - 5 meters

New area = (x + 5)(x - 5 )

Using the identity(a + b)(a - b) = a² - b² we get

(x + 5)(x - 5 ) =x² - 5²

= x² - 25

Area difference square - rectangle =
x² - (x² - 25) = x² - x² + 25

Step-by-step explanation:

[tex]\displaystyle \sum^{29}_{n=2}80\left(1.23\right)^{n-2}[/tex]

The given sigma notation means

As 80(1.23)ⁿ⁻² is exponential, the series is geometric.

[tex]\boxed{\begin{minipage}{5.5 cm}\underline{Geometric sequence}\\\\$a_n=ar^{n-1}$\\\\where:\\\phantom{ww}$\bullet$ $a$ is the first term. \\\phantom{ww}$\bullet$ $r$ is the common ratio.\\\phantom{ww}$\bullet$ $a_n$ is the $n$th term.\\\phantom{ww}$\bullet$ $n$ is the position of the term.\\\end{minipage}}[/tex]

Therefore, the first term, a, is 80 and the common ratio, r, is 1.23.

The formula for the sum of the first n terms of a geometric series is:

[tex]S_n=\dfrac{a(1-r^n)}{1-r}[/tex]

As the exponent of the sigma notation is (n - 2) rather than (n - 1), and the given values of n are from n = 2 to n = 29, we need to find the sum of the first 28 terms.

Therefore, substitute a = 80, r = 1.23 and n = 28 into the sum formula:

[tex]\implies S_{28}=\dfrac{80\left(1-1.23^{28}\right)}{1-1.23}[/tex]

[tex]\implies S_{28}=114125.755...[/tex]

Therefore, the value of the given expression to the nearest integer is 114,126.

Answer: If there are 12 identically matched points on the picture of the sun, then the angle between any two adjacent points is 360/12 = 30 degrees.

When you line up two suns directly on top of each other, all of the matched points on the top sun will line up with the corresponding matched points on the bottom sun.

To find the least number of degrees that you can rotate the top sun so that the two suns are perfectly aligned again, you need to find the smallest angle that is a multiple of 30 degrees.

The smallest angle that is a multiple of 30 degrees is 360 degrees, which is equivalent to rotating the top sun all the way around once. Therefore, the least number of degrees that you can rotate the top sun so that the two suns are perfectly aligned again is 360 degrees.

When the distribution is essentially symmetric or bell-shaped, with no extreme outliers, the mean is a useful measure of the center to employ. This is so because the mean can be impacted by extreme values, which can drive it away from the distribution's center, and is sensitive to the values of all the observations in the data set.

In statistics, in addition to the mode and median, the mean is one of the measures of central tendency. Simply put, the mean is the average of the values in the given set. It indicates that values in a particular data set are distributed equally. The three most frequently used measures of central tendency are the mean, median, and mode. Assuming that the data is regularly distributed and that the mean is a suitable measure of center, the mean is often chosen when doing specific statistical procedures, such as linear regression and hypothesis testing.

The median, however, might be a better indicator of the center to utilize if the distribution is skewed or contains severe outliers. In these situations, the median better captures the distribution's midpoint and is less vulnerable to high extremes.

Which center measure to choose ultimately comes down to the specifics of the data collection and the objectives of the investigation.
