0 divided by 8 is the answer

The expression which is undefined is:

                               8÷0

Undefined expression--

It is a expression which is meaningless.

In real numbers if we divide a non-zero number by 0 then the expressions becomes meaningless.

1)

-8÷(-8)

On dividing the non-zero number by the number itself we get the resultant as 1.

i.e.

-8÷(-8)=1

2)

-8÷8

On dividing a number by the negative of same number we get the resultant as: -1

3)

0÷8

On dividing zero by any non-zero number we get the resulting value as 0.

i.e.

0÷8=0

4)

8÷0

Here in the denominator we have the number as zero.

Hence, the expression is undefined.

You will notice that the answer to problem 8 does not agree with any of the offered choices. The time period of 22.8 years is 12 times the half-life of the substance, so there will be (1/2)^12 = 1/4096 of the original amount remaining. The time periods corresponding to the amounts shown range from 1.37 years to 16.4 years.

For half-life problems, I find it convenient to use the decay factor (0.5^(1/half-life)) directly, rather than convert it to e^-k. If you do convert it to the form ...

Answer: Option B

[tex]y=0.5x +0.75[/tex]

Step-by-step explanation:

The equation modeling this situation is a linear equation of the form

[tex]y = mx + b[/tex]

Where x is the slope and b is the intercept with the y axis.

To find the equation of a line we need two points that belong to the line.

We know that when it is empty the jug weighs 0.75 lib.

This is:

When x = 0, y = 0.75

Then when the jug contains 3 cups of water it weighs 2.25 pounds.

This is:

When x = 3, y = 2.25

We already have the two points

Then we find the slope of the straight

[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

[tex]y_2 = 2.25\\\\y_1=0.75\\\\x_2=3\\\\x_1=0[/tex]

[tex]m=\frac{2.25-0.75}{3-0}[/tex]

[tex]m = 0.5[/tex]

The equation is:

[tex]y=0.5x +b[/tex]

We substitute the point (0, 0.75) in the equation and solve for b

[tex]0.75=0.5(0) +b[/tex]

[tex]b=0.75[/tex]

Finally the equation is:

[tex]y=0.5x +0.75[/tex]

Step-by-step explanation:

Andy earns $8.50 per hour by dividing the total amount he earns ($34).

To find out how much Andy earns for each hour he works, you need to divide the total amount he earns by the number of hours he works on Saturday morning. If Andy earns $34 over 4 hours, his hourly wage is calculated as follows:

Divide $34 by 4 hours.

$34 / 4 hours = $8.50 per hour.

So, Andy earns $8.50 per hour.

Related Scenarios

At an hourly wage of $10 per hour, a similar worker like Marcia Fanning is willing to work 36 hours per week.

With increased hourly wages between $30 and $40, Marcia decides to work 40 hours per week.

When offered $50 per hour, she chooses to reduce her hours to 35 per week, likely to balance her work and leisure time in a way that maximizes her utility.

These examples illustrate how an increase in hourly wage can influence the number of hours a person is willing to work to balance overall life satisfaction and economic benefits

Answer:

b. 10

Step-by-step explanation:

The triangles are all similar, so you have ...

hypotenuse/short side = x/4 = 25/x

Cross multiplying gives ...

x^2 = 100

x = 10 . . . . . . . take the square root

Answer:

The answer is b) 10

Step-by-step explanation:

We have to use the theorem of the cathetus or  leg rule,  that says "Each leg of the right triangle is the mean proportional between the hypotenuse and the part (projection) of the hypotenuse directly below the leg"

hypotenuse/leg =leg/part or b²= m*a

In this case,  

hypotenuse= m

leg=x

part= 4

So,  

x= √((21+4)*4)

x= √((25)*4)

x= √100

x= 10

Answer: So the final answer would be width is 6x + 6

Step-by-step explanation: The formula for Area is Length x width.

So A = (2x + 6)(3x) and the result is: 6x^2 + 18x

Now, let y be the width of rectangle B.

(x+2) (y) = 6x^2 + 18x + 12

(x+2) y = 6(x+1)(x+2)

y = 6(x+1)

Answer:

18% reduction leaves 82% remaining. 82% of $2150 = .82(2150) = $1763.

Answer:

Retail Price = $1763

Step-by-step explanation:

List price of article = $2150

Percentage discount given = 18%

Then value of discount on the list price = 18% of $2150

                                                                 = [tex]\frac{(2150)(18)}{100}[/tex]

                                                                 = $387

Now the retail price of the article = List price - discount given

                                                       = $2150 - $387

                                                       = $1763

Therefore, Retail price of the article will be $1763

APR = 21.6% = 0.216

The APR is the annual periodic rate

The monthly periodic rate is the annual periodic rate divided by 12, because there are 12 months in a year

Monthly periodic rate = APR / Number if months in a year

= 21.6% / 12

= 1.8%

The APR on Leslie's credit card is currently 21.6%. The monthly periodic rate will be 1.8%.

The full name of APR is the annual percentage rate. It is defined as the percentage rate applied on borrowing money in the form of interest but APR is applied annually.

It is given that, the APR on Leslie's credit card is currently 21.6%.

APR = 21.6% = 0.216

Since there are 12 months in a year, the annual periodic rate is divided by 12 to determine the monthly periodic rate.

Monthly periodic rate = APR / Number of months in a year

= 21.6% / 12

= 1.8%

Thus, the APR on Leslie's credit card is currently 21.6%. The monthly periodic rate will be 1.8%.

Answer:

The domain for f(x) is all real numbers greater than or equal to 3.

Step-by-step explanation:

[tex]f(x)= \frac{3}{x+2} - \sqrt{x-3}[/tex]

To solve the above equation, the value of x should be greater than or equal to 3, as we have the term [tex]\sqrt{x-3}[/tex] and if value is less than 3, the term inside the square root will be negative and we cannot find the square root of negative numbers.

So, The domain for f(x) is all real numbers greater than or equal to 3.

Answer:

"greater"

Step-by-step explanation:

The domain is the set of x values for which a function is defined.

When we have a square root is a function, we need to remember that square root can't be negative. Thus, anything under the root would need to be GREATER THAN or EQUAL to 0.

Thus

x - 3 ≥ 0

For a set of data, the average squared deviation from the mean, with a denominator of n-1 is called the: Sample Variance.

Answer: Sample Variance

For a set of data, the average squared deviation from the mean, with a denominator of n-1 is called the sample variance.

Sample variance can be defined as the expectation of the squared difference of data points from the mean of the data set. It is an absolute measure of dispersion and is used to check the deviation of data points with respect to the data's average.

Suppose a data set is given as 3, 21, 98, 17, and 9. The mean (29.6) of the data set is determined. The mean is subtracted from each data point and the summation of the square of the resulting values is taken. This gives 6043.2. To get the sample variance, this number is divided by one less than the total number of observations. Thus, the sample variance is 1510.8.

Sample variance is used to measure the spread of the data points in a given data set around the mean. All observations of a group are known as the population. When the number of observations start increasing it becomes difficult to calculate the variance of the population. In such a situation, a certain number of observations are picked out that can be used to describe the entire group. This specific set of observations form a sample and the variance so calculated is the sample variance.

[tex]S^{2}= \frac{\sum_{i=1}^{n}(x_{i}-\mu )^{2} }{n-1}[/tex]

Hence, For a set of data, the average squared deviation from the mean, with a denominator of n-1 is called the sample variance.

Both Laura and Rob are correct in finding the decimal equivalent of a fraction.

A fraction is a mathematical expression representing a part of a whole. It consists of a numerator (top number) indicating the part being considered and a denominator (bottom number) representing the total number of equal parts. Fractions are used for division, ratios, and comparisons in mathematics.

To find the decimal equivalent of a fraction, you can use either method mentioned by Laura or Rob. Laura's method involves writing an equivalent fraction with 100 as the denominator and then dividing the numerator by the denominator. For example, 39/50 can be written as 78/100, which is equal to 0.78 as a decimal. Rob's method involves dividing the numerator (39) by the denominator (50) directly, which also gives you the decimal value of 0.78.

Answer:

Your answer would be 3/7 or [tex]\frac{3}{7}[/tex]

____________________________________________________

Step-by-step explanation:

In this type of question, we would need to find out the chances of getting something as an outcome, and that would be expressed as a fraction.

In order to find out the chance (or likeliness) of an outcome, we would need o use the information provided in the question.

Let's give you some key information that was given to us.

Key information:

4 animal characters

3 Human characters

With the information above, we can figure out what would be the probability of an outcome.

The question is saying "what is the probability of the computer picking a human character." That means that the amount of human characters would go on our numerator.

There's not only human characters, but there are 4 animal characters too, so that would be used to give us our total. the "4" will be added to our denominator.

Now, let's write it in a fraction.

Fraction: [tex]\frac{numerator}{denominator}[/tex]

We know that we are trying to find the probability of getting a human character, so "3" would go on our numerator.

For our denominator, we would add up both numb ers since it would have to be the total amount of options in order to find the probability, and that would be "7" since 4 + 3 = 7.

When you put those into a fraction. Your FINAL answer would be:

3/7 or [tex]\frac{3}{7}[/tex]

Answer:

Amanda = 22

Alisa = 26

Step-by-step explanation:

Amanda : Alisa = 11 : 13

Amanda : Alisa = 11x : 13x

Alisa gives 10 dresses to Amanda.

Amanda = 11x + 10

Alisa = 13x - 10

Amanda will have twice as many dresses as Alisa has.

11x + 10 = 2(13x - 10)

11x + 10 = 2(13x - 10)

11x + 10 = 26x - 20

15x = 30

x = 2

Amanda

= 11 x 2

= 22

Alisa

= 13 x 2

= 26

Amanda has 22 dresses, and Alisa has 26 dresses. This is calculated by solving the equations given in the problem according to the ratio and conditions provided. The number of dresses each girl has fits the criteria set by the original problem.

Solving the Ratio Problem

To find the number of dresses Amanda and Alisa have, we start by setting up the ratio and the conditions given:

Let the number of dresses Amanda has be 11x and the number Alisa has be 13x. The ratio of their dresses is 11:13.

If Alisa gives 10 dresses to Amanda, Amanda's dresses become 11x + 10 and Alisa's dresses become 13x - 10. According to the problem, Amanda will then have twice as many dresses as Alisa:

Expanding and simplifying the equation:

So, the number of dresses:
