NEED HELP WITH A MATH QUESTION TO FIND THE VALUE OF X

Answer:

[tex]\frac{\sqrt{x} }{2x}[/tex]

Step-by-step explanation:

Rationalize the denominator first (keep in mind we are NOT solving this because there is no equals sign here.  We are merely simplifying.)

[tex]\frac{\sqrt{5x} }{x\sqrt{20} } *\frac{\sqrt{20} }{\sqrt{20} } =\frac{\sqrt{100x} }{20x}[/tex]

Now simplify by taking the square root of 100 to get:

[tex]\frac{10\sqrt{x} }{20x}[/tex]

Divide numerator and denomiator by 10 to get:

[tex]\frac{\sqrt{x} }{2x}[/tex]

Answer:

Step-by-step explanation:

Lots, even if you make this a combination problem. I'm going to treat it as a permutation first and then we'll look into a combination.

52 P 5 is the same thing as a counting problem

The first card drawn is 1 of 52

The second one drawn is 1 of 51

The third one drawn is 1 of 50

The 4th one drawn is 1 of 49

The 5 one drawn is 1 of 48

The answer you should get is 311 875 200

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

If your calculator does this then you should put in 52P5 and it will give you the possible outcomes.  Remember the question asks you the number of outcomes not the probability.

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

The above number treats the order as different.

So 12345 is not the same as drawing 12354.

Those 2 sets of cards are counted as 2 not one.

I believe this to be the best answer.

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

But if order does not matter, and you want 1 2 3 4 5 to be the same thing as  1 2 3 5 4 the problem is a combination problem. Ignoring the suits the answer is

52 C 5

which is 52 * 51 * 50 * 49 * 48 / 5! = 2598960

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

I don't know how far into the course you are but the actual answer would have to account for the suits. This solution assumes that the actual card drawn remains upside down, that is, if it is the king of hearts, you don't know it.

Answer:

  Let (x+1) = the larger number

Step-by-step explanation:

Two consecutive numbers differ by 1. The larger is 1 more than the smaller. The expression for 1 more than x is (x+1).

Answer:

[tex]3x-4y=-40[/tex]

Step-by-step explanation:

The standard form of a linear equation is  [tex]ax+by=c[/tex].

The given line has equation:

[tex]y-4=\frac{3}{4}(x+8)[/tex]

This is the point-slope form of the given line.

To find the standard form, we clear the fraction

[tex]4y-16=3(x+8)[/tex]

We expand the parenthesis now to get:

[tex]4y-16=3x+24[/tex]

We group the variables on the LHS and the constants on the RHS.

[tex]4y-3x=24+16[/tex]

[tex]-3x+4y=40[/tex]

Multiply through by -1

[tex]3x-4y=-40[/tex]

This is of the form: [tex]ax+by=c[/tex].

About how

As with any graphing problem, when doing it by hand, one chooses enough points to give the general shape of the curve. In some cases, quite a few points may be required. It is often helpful to use a spreadsheet for calculating the point values. Here, we've graphed the equations using "technology"--a graphing calculator.

Answer:

[tex]\frac{7}{x}[/tex]

Step-by-step explanation:

Let x represent the number.

We are supposed to write an expression for our given statement.

We have been given that the quotient of 7 and a number. This means that 7 is divided by the number 'x'.

We can represent this information in an expression as:

[tex]\frac{7}{x}[/tex]

Therefore, our required expression would be [tex]\frac{7}{x}[/tex].

Step-by-step explanation:

The slope-intercept form of an euqtion of a line:

y = mx + b

m - slope

b - y-intercept

x = a (a - any real number)

It's the equation of a vertical line. A vertical line has an undefined slope. They also do not have a y-intercept, because they run parallel to the y axis.

Therefore given equations can not write in the slope-intercept form.

Step-by-step explanation:

To solve, use FOIL. FOIL:

First

Outside

Inside

Last

Solve "First":

(3x)(-3x) = -9x²

Solve "Outside":

(3x)(-5) = -15x

Solve "Inside":

(-5)(-3x) = +15x

Solve "Last":

(-5)(-5) = +25

Combine like terms:

-9x² - 15x + 15x + 25

-9x² (-15x + 15x) + 25

-9x² + 25

-9x² + 25 is your answer.

For this case we have the following formula:

[tex]nP_ {r} = \frac {n!} {(n-r)!}[/tex]

Where:

P: It is the number of permutations

n: It is the number of objects

r: It is the number of selected objects

According to the data we have to:

[tex]n = 12\\r = 5[/tex]

Substituting:

[tex]12P_ {5} = \frac {12!} {(12-5)!} = \frac {12 * 11 * 10 * 9 * 8 * 7!} {7!} = 12 * 11 * 10 * 9 * 8 = 95,040[/tex]

Finally, the number of permutations is 95,040

ANswer:

95,040

Variance

The standard deviation is related to the variance. The standard deviation measures the variation or dispersion of a set of data and is represented by the Greek letter sigma [tex]\sigma[/tex], while the variance measures how far a set of  numbers are spread out from their average value. The variance is obtained by squaring the standard deviation, so the variance can be found as [tex]\sigma^{2}[/tex]

Vacations are not a typical application of investors' money as they do not contribute to future profitability or growth of a business, unlike product improvement, expansion, or employee salaries.

The question asks about a typical application of investors' money which is not common. Of the options provided, vacations would not be a typical application of investor funds. Investors typically allocate capital to a business with the expectation of earning future profits.

Common expenses that may constitute investment in a firm include product improvement, expansion, and even employee salaries, as these are directly related to the operations and growth potential of the business.

Capital invested in the business is expected to generate future income and growth, through means such as buying long-term assets like machinery, building new plants, or initiating research and development projects. It's unlikely that investors would find vacations a viable investment category as it generally does not contribute to the future profitability or growth of a business enterprise.

given that 1 ox eats as much as 10 sheep:

4 oxen = 40 sheep

therefore,

first farmer:  the equivalent of 40 sheep

second farmer:  30 sheep

that means 30+40 = 70 animals eating

$140 ÷ 70 = $2

so it is $2 per eat

2 x 40 = $80 for the first farmer's oxen

2 x 30 = $60 for the second farmer's sheep

Answer:

$80

Step-by-step explanation:

Since if 1 ox is equal to 10 sheep, then the first farmer posesses the equivalent of 40 sheep. With 70 sheep in total, then one sheep is worth 2 dollars. The first farmer has a total of 4 oxen, equivalent to 40 sheep. 40 times 2 is 80, so the answer is 80 dollars

Answer:

B. T–5,0 ∘ R0,90°(x, y)

Step-by-step explanation:

Just took Quiz.

Transformation involves changing the size and position of a shape.

The transformation rule from DEF to D"E"F is [tex]\mathbf{(b)\ T-5,0 \circ R0,90^o(x, y)}}[/tex]

From the complete question (see attachment), we have the following observations.

The 90 degrees counterclockwise rotation is represented as:

[tex]\mathbf{R0,90^o(x, y)}[/tex]

The left translation by 5 units is represented as:

[tex]\mathbf{T-5,0(x, y)}[/tex]

When both transformations are combined, we have:

[tex]\mathbf{T-5,0 \circ R0,90^o(x, y)}}[/tex]

Hence, the transformation rule from DEF to D"E"F is [tex]\mathbf{(b)\ T-5,0 \circ R0,90^o(x, y)}}[/tex]

Answer:

  segment PQ and segment P double prime Q double prime are congruent after the translation, but not after the dilation

Step-by-step explanation:

Translation and dilation have no effect on angles. All angles are congruent after either or both of translation and dilation.

Translation has no effect on size, so segments are congruent after translation. Dilation changes size, so segments are not congruent after dilation.

___

Comment on the problem wording

Ordinarily, the first transformation (translation) would result in figure P'Q'R', so P'Q' would be congruent to PQ. Then the second transformation (dilation) would change figure P'Q'R' to figure P''Q'' R'', which is no longer congruent to either figure P'Q'R' or figure PQR.

That is, talking about "segment P double prime Q double prime ... after the translation, but not the dilation" makes no sense, because there is no such segment. The segment that exists after the translation, but not the dilation, is segment P'Q'.

Answer:

line PQ and line P double prime Q double prime are congruent after the translation, but not after the dilation

Answer:

  $16,000

Step-by-step explanation:

Revenue is the product of price and the number sold. Using the given relation for number sold, the revenue as a function of price is ...

  R(p) = p(-40p +1600) = -40p(p -40)

This is the equation of a quadratic that opens downward and has zeros at p=0 and p=40. The vertex is halfway between those zeros, at p=20. The revenue at this price is ...

  R(20) = -40·20(20 -40) = 16,000 . . . . dollars

Answer:

  (6, -2)

Step-by-step explanation:

To get to x=1 from x=-2, you must add 3 to the x-coordinate. Only one answer choice has an x-coordinate that is 3 more than that of the given point:

  3 + 3 = 6

The image point is (6, -2).

_____

Check

To get from a y-coordinate of 5 to an image point y-coordinate of 1, you must subtract 4. If you subtract 4 from the y-coordinate of (3, 2), you get 2-4 = -2, the y-coordinate in the chosen answer above.

Answer:

2 out of 5 or 6 out of 15

Step-by-step explanation:

In this pattern, there is two people ordering it every five times. You can write it out as 6/15 or simplify it as 2/5 (six-fifteenths and two-fifths)

The simulated probability that a customer will order the small beverage is:

                 [tex]\dfrac{2}{5}=0.4[/tex]

The  1, 2, and 3 to represent small, medium, and large, respectively.

The simulation is as follows:

2   2   3   1   1   2   2   3   1   1    3    2   1    1    3

There are a total outcomes= 15

Also, the number of outcomes that the customer will order small beverage is: 6

( Since,  6 times such that 1 has occurred.

As 1 represent the simulation that the beverage comes in small size )

Hence, the simulated probability is:

       [tex]\dfrac{6}{15}=\dfrac{2}{5}=0.4[/tex]

Answer:

B. Clara incorrectly combined the r coefficients. The correctly simplified expression is 6b-3r

Step-by-step explanation:

Simplifying the expression by opening the brackets we get:

8b - 4r-2b+r

A negative coefficient multiplied by a negative coefficient results to a positive coefficient.

Combining like terms together:

8b-2b-4r+r

=6b-3r

The correct answer is A. She incorrectly combined the b coefficients. The only symbols that have an effect on a number is the symbol BEFORE the number. Thus, in 2b-r, they would separate into 2b and -r.

Using this knowledge, combine like terms the right way.

8b+2b=10b

-4r-r=-5r

The correct equation is 10b-5r

Hope this helps!
