3/6 not a integer

Final answer:

The fraction 3/6 is not an integer because it equals 0.5, which is a fraction and not a whole number.

Explanation:

To determine which of these values is not an integer, we need to perform the division for each fraction:

Therefore, 3/6 is not an integer because when you divide 3 by 6, you get a fractional number rather than a whole number.

The answer is D or -30

The value of the expression for the given values of the variables is -30.

The given expression is 4a+7b+3a-2b+2a, the values of the variables a=-5 and b=3.

We need to evaluate the expression for the given values of the variables.

To evaluate an algebraic expression means to find the value of the expression when the variable is replaced by a given number. To evaluate an expression, we substitute the given number for the variable in the expression and then simplify the expression using the order of operations.

Now, put a=-5 and b=3 in the given expression and simplify.

That is, 4a+7b+3a-2b+2a=4(-5)+7(3)+3(-5)-2(3)+2(-5)

=-20+21-15-6-10

=-30

Therefore, the value of the expression for the given values of the variables is -30.

p(10) is the profit, in dollars, from selling 10 books. Replace every copy of x with 10 and simplify

p(x) = 8x-10

p(10) = 8*10-10 .... every x is replaced with 10

p(10) = 80-10

p(10) = 70

So the profit is $70

For the function p(x) = 8x - 10, the profit for selling 20 books is $150.

Explanation:

In the problem, the function p(x) = 8x - 10 represents the profit, in dollars, for selling 'x' books. When it's stated that p(20) = 150, it means that by substituting the value of 'x' as 20 in the function, we get the value as 150. In terms of the problem, it means that the profit for selling 20 books is $150.

Let's break down the problem step by step.

1. You're given the function p(x) = 8x - 10, which represents the profit, in dollars, for selling x books. In this equation, p(x) is the profit, and \(x\) is the number of books sold.

2. You're asked to evaluate the function at x = 20, which means you want to find p(20). To do this, substitute x = 20 into the function and calculate the result.

  p(20) = 8(20) - 10

3. Perform the calculation:

  p(20) = 160 - 10

4. Complete the subtraction:

  p(20) = 150

So, p(20) = 150, which means that the profit for selling 20 books is $150. This is the interpretation of the statement "p(20) = 150" in terms of the problem.

Hey there,

Here is your answer:

a - 47 = more time spent

In this mathematical problem, Abby's time is represented as x and the difference in time between Abby's and Susanna's work can be modeled by the equation x-47=y, where y is the extra time Abby spends. A number line can be used to visualize this problem, but without knowing Abby's time, we cannot determine y.

The subject of this problem is mathematics and it discusses time spent by two individuals on their project. We know that Susanna spends 47 minutes on her project. However, we do not know how much time Abby spends on her project. We could represent the time Abby spends on her project as x.

To visualize the situation, we can draw a number line. Place a point at 47 which represents Susanna's time. Then place another point at x which represents Abby's time.

The difference in time between Susanna and Abby can be represented by the equation x - 47 = y, where y is the number of extra minutes Abby spends working on her project.

Without any additional information on how much time Abby spent on her work, it's impossible to give a specific answer.

The mean number of people in each spinning class last week is calculated by summing up the total number of attendees and dividing by the number of classes. The mean attendance for last week was 21.

To calculate the mean number of people attending the spinning class each day, you would add up the total number of people for the week and then divide by the number of classes.

The given numbers are:

So the sum of the attendees is: 13 + 23 + 24 + 31 + 14 = 105

The mean is then calculated by dividing the total by the number of days, which is 5 in this case:

Mean = Total ÷ Number of Days = 105 ÷ 5 = 21

So, the mean number of people in each class last week was 21.

To simplify the expression √7{x 5} ×  √7{x 5}, you can multiply the radicands together and simplify the result.

To simplify the expression √7{x 5} ×  √7{x 5}

We can use the properties of radicals to simplify the expression. When multiplying radicals with the same index, we can simplify by multiplying the radicands together. In this case, the radicands are both x5, so the simplified form will be:

√7{x 5} ×  √7{x 5} = √7{x 5 × x 5} = √7{x10}

Therefore, the simplified form of the expression is √7{x10}.

Answer:

Tony pays $6.75 for his item, & Tanya pays $9 for her items

Step-by-step explanation:

Let Tanya's item be x, and Tony's be y. Set the system of equality:

3x = 4y

y = x - 2.25

Plug in x - 2.25 for y in the first equation

3x = 4(x - 2.25)

Distribute 4 to all terms within the parenthesis

3x = 4x - 9

Isolate the x. Subtract 4x from both sides

3x (-4x) = 4x (-4x) - 9

3x - 4x = -9

-x = -9

Isolate the x. Divide -1 from both sides

(-x)/-1 = (-9)/-1

x = 9

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

Plug in 9 for x in the equation

y = x - 2.25

y = (9) - 2.25

y = 6.75

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

Tony pays $6.75 for his item, & Tanya pays $9 for her items

a single die being rolled to a number less or equal to 2

Final answer:

The complement of rolling a number greater than 2 on a single six-sided die is rolling a 2 or less, which has a probability of 1/3.

Explanation:

In the context of a single six-sided die roll, the complement of rolling a number greater than 2 would be rolling a number that is 2 or less, which in this case includes rolling a 1 or a 2. Each face of a fair six-sided die has an equal chance of landing face up, giving us a probability of 1/6 for landing on a specific number. Since there are two outcomes that are 2 or less (1 and 2), we simply add their probabilities to get the complement. Thus, the complement of rolling a number greater than 2 is:

P(rolling a 1 or 2) = P(rolling a 1) + P(rolling a 2)
= 1/6 + 1/6
= 1/3.

Therefore, there is a 1/3 chance of rolling a number that is 2 or less when rolling a single fair six-sided die.

Answer: Yes it is possible. Angle DCF is also 50 degrees

=================================================

Check out the image attachment below. On that image, I've marked that angle EBA is congruent to angle BAC by the alternate interior angle theorem. Those angles are shown in red. Furthermore, angle BAC is congruent to DCF (corresponding angles) using a green marker. Finally, using the transitive theorem, you can connect the statements in a chain to say that angle EBA is congruent to angle DCF, which is why angle DCF is 50 degrees as well.

Answer:

17%

Step-by-step explanation:

Final answer:

Ella owns 15% of Fitz Incorporated, and the remaining 85% is shared equally among 5 other shareholders. Thus, each of these shareholders owns an equal share of 17% of the corporation.

Explanation:

The question asks about corporate stock and how it relates to the percentage of ownership in a corporation. Ella owns 15% of Fitz Incorporated, and the remaining 85% is owned equally by 5 other shareholders. To find the percentage each of these shareholders owns, we divide the remaining percentage by the number of shareholders.

The calculation would be:

Subtract the percentage owned by Ella from the total, which is 100% - 15% = 85%.

Divide this remaining percentage (85%) by the number of other shareholders, which is 5.

85% / 5 = 17% ownership for each of the other shareholders.

So, each of the remaining 5 shareholders owns 17% of the corporation.
