Answer:

3

Step-by-step explanation:

We have to find the smallest possible factor of 15 and multiple of 3.

The smallest factor of any positive integer is 1.

The smallest multiple of any positive integer is the integer itself. So the smallest multiple of 3 would be 3 itself.

\(1 * 3 = 3\)

And 3 is the answer.

The particles contain 5.199 mol. The result is obtained by dividing the number of particles by the Avogadro number.

Avogadro number is the number of particles contained in 1 mol of any substance. It is 6.022 × 10²³ particles/mol.

The number of particles of a substance can be expressed as

N = n × NA

Where

The number of particles of a substance is 3.131 × 10²⁴ particles. Find the number of moles!

With the Avogadro number, the number of moles would be

N = n × NA

3.131 × 10²⁴ = n × 6.022 × 10²³

n = (3.131 × 10²⁴) / (6.022 × 10²³)

n = 0.5199 × 10¹

n = 5.199 mol

Hence, there are 5.199 mol contained in the particles.

The answer is A.

Answer:

The corresponding point is (-8, -6).

Step-by-step explanation:

Given that

(-6,-6) lies on the graph of \(f(x)\)

A function is represented in the form:

\(y = f(x)\)

i.e. (-6,-6) means value of x = -6 is put and value y came out as -6.

\(f(-6) = -6\)

Now, we have to find the corresponding point on \(f(\frac{3}{4}x)\).

We know the value of \(f(-6)\)

Let us find the value of x where \(\frac{3}{4}x\) becomes equal to -6

\(\dfrac{3}{4}x=-6\\\Rightarrow 3x=-24\\ \Rightarrow x =-8\)

So, let us put value of \(x = -8\) in \(f(\frac{3}{4}x)\):

\(f(\frac{3}{4}\times (-8))\\\Rightarrow f(3\times (-2))\\\Rightarrow f(-6) = -6\)(as per given statement)

So, the corresponding point is (-8, -6).

Step-by-step explanation:

Step 1:  Find the amount Elmer's funds decreased after purchasing the rabbits:

Let x represent Elmer's funds.

Since Elmer bought five rabbits for $10 each, he lost $10 5 times.

x - (10 * 5)

x - 50

Thus, Elmer lost (spent) $50 for the 5 rabbits.

Step 2:  Find the amount Elmer's funds decreased after purchasing the  cupboards:

Since Elmer bought four cupboards for $70 each, he lost $70 4 times:

x - (50 + (70 * 4))

x - (50 + 280)

x - 330

Thus, after purchasing the rabbits and cupboards, Elmer lost $330.

Step 3:  Find the amount Elmer's funds increased after finding the twenty-dollar bill:

Since Elmer found a twenty-dollar bill, he gained $20

x - (330 + 20)

x - 310

Step 4:  Find the amount Elmer's funds increased after returning one rabbit:

Since Elmer returned one rabbit, he gained $10:

x - (310 + 10)

x - 300

Thus, Elmer's funds changed totally by -$300.

Putting all the information together, we have:

x - 10 - 10 - 10 - 10 - 10 - 70 - 70 - 70 - 70 + 20 + 10

x - 50 - 280 + 30

x - 330 + 30

The best description of the relationship between the y-axis and the line connecting F to F' after reflection over the y-axis is that they are perpendicular to each other.

When a triangle is reflected over the y-axis, its vertices swap their x-coordinates while keeping their y-coordinates the same. Let's consider the points F and F' on the reflected triangle.

The line connecting F to F' is the vertical line on the y-axis because the reflection over the y-axis does not change the y-coordinate. The y-axis itself is also a vertical line.

Since both the line connecting F to F' and the y-axis are vertical lines, they are perpendicular to each other. This is because perpendicular lines have slopes that are negative reciprocals of each other, and vertical lines have undefined slopes.

Therefore, the best description of the relationship between the y-axis and the line connecting F to F' after reflection over the y-axis is that they are perpendicular to each other.

To find Ted's current age, set up equations using Fred's age and solve for Fred's age. Use the information that Ted was twice as old as Fred seven years ago to find Fred's current age. Finally, use Fred's current age to find Ted's current age.

Ted's current age can be found by first using algebra to set up equations based on the information given in the problem. Let x be Fred's current age. Then, Ted's current age is x + 4. Seven years ago, Ted was x + 4 - 7 = x - 3 years old, and Fred was x - 7 years old. The problem states that Ted was twice as old as Fred seven years ago, so we can set up the equation 2(x - 7) = x - 3. Solving for x, we get x = 11, which means Fred is currently 11 years old. Therefore, Ted is currently 11 + 4 = 15 years old.

The value of X = 25.

Solution:

The two equations are

(i) the first condition is difference of x and y is 14

x - y = 14 ---------equation 1

(ii) the second condition of the given data is value of x is 3 times more than two times of y value.

x - 2y = 3 --------equation 2

From equation 2, we have to separate two variables x and y,

x = 3 + 2y  --------equation 3

We have to Substitute equation 3 in equation 1

3 + 2y - y = 14

3 + y = 14

y = 14 - 3

y = 11

Substitute y = 11 in equation 1........

x - 11 = 14

x = 14 + 11

Answer:

Step-by-step explanation:

Given the difference of x and y is 14, and the difference of x and 2y is 3, you want two equations, their graph, and the value of x.

The difference of 'a' and 'b' is (a -b). Here, the two differences are expressed as the equations ...

The attachment shows a graph of these equations. Their point of intersection is (25, 11), meaning the value of x is 25.

The graph of the first equation is easily drawn by recognizing the x- and y-intercepts are 14 and -14, respectively.

The graph of the second equation will go through the x-intercept point of (3, 0) and the y-intercept point of (0, -3/2). It is probably easier to graph this by hand by considering the x-intercept point and the slope of 1/2.

Since we're only interested in the value of x, it is convenient to eliminate the variable y. We can to that by subtracting the second equation from twice the first:

  2(x -y) -(x -2y) = 2(14) -(3)

  x = 25 . . . . . . . . . simplify

(a) The dot product of A and B is given by: A · B = (2î + 3ĵ + 4k) · (î - 2ĵ + 3k)= 2(1) + 3(-2) + 4(3)= 2 - 6 + 12 = 8

Therefore, A · B = 8.

(b) The angle between two vectors A and B is given by:

θ = cos^(-1)((A · B) / (|A| |B|))

In this case, |A| is the magnitude of vector A and |B| is the magnitude of vector B. The magnitude of a vector is given by the square root of the sum of the squares of its components.

|A| = √(2² + 3² + 4²) = √(4 + 9 + 16) = √29

|B| = √(1² + (-2)² + 3²) = √(1 + 4 + 9) = √14

Plugging in the values:

θ = cos^(-1)(8 / (√29 √14))

(c) The scalar component of vector A in the direction of vector B is given by:

A_B = (A · B) / |B|

Plugging in the values:

A_B = 8 / √14

Which is equal to  64

No doubt, the expeced answer is 2. This is because you would ordinarily change the problem to 59200/925 for long division by hand.

For this quotient, you don't need any, because the quotient is 64, a multiple of 4, so the numbers being subtracted are always integers.

If you were dividing 591 by 9.25, you would need an infinite number of zeros—because the decimal portion of the quotient is a repeating decimal with a period of 3 digits.

The probability that a shutdown is due to hardware failure given that there is a shutdown is 0.346.

To find the probability that the shutdown is due to hardware failure given that there is a shutdown, we need to use Bayes' theorem.

Let H be the event that the shutdown is due to hardware failure, and S be the event that there is a shutdown. Then we need to find P(H|S).

Using the formula for Bayes' theorem:

P(H|S) = P(S|H) * P(H) / P(S)

We already have P(H) = 0.45, and P(S|H) = 0.43, the probability of a shutdown given hardware failure.

To find P(S), we need to use the law of total probability:

P(S) = P(S|H) * P(H) + P(S|E) * P(E) + P(S|S) * P(S)

where E is the event of electronic failure, and S is the event of software failure.

We are given P(S|E) = 0.95, P(E) = 0.30, P(S|S) = 0.09, and P(S|H), P(H) as calculated above.

Substituting the values:

P(S) = 0.43 * 0.45 + 0.95 * 0.30 + 0.09 * 0.25 = 0.558

Finally, substituting all values into Bayes' theorem:

P(H|S) = 0.43 * 0.45 / 0.558 = 0.346

Therefore, the probability that a shutdown is due to hardware failure given that there is a shutdown is 0.346.

Answer: 1 hand = 0.22... cubits.

Step-by-step explanation:

We want to write the relation between hands and cubits.

We know that there are 9 hands in 2 cubits.

So we can write:

9 hands  = 2 cubits.

Now, we want to have an unit in the left side (so we can see how many cubits are equal to exactly one hand).

Then we can divide by 9 in both sides of the equality.

(9 hands)/9 = (2 cubits)/9

1 hand = 0.22... cubits.

The expression to find the perimeter is 12x² - 6, and the perimeter when x= 1.5 is 21

Step-by-step explanation:

The perimeter is the sum of all side lengths for a 2d shape, such as this triangle. Our perimeter is thus

4x² - 3 + 4x² - 2 + 4x² - 1

We can then separate our variables and constants to make it

4x² + 4x² + 4x² - 3 - 2 - 1

Add the constants to get

4x²+4x²+4x²  - 6

To add variables, we must first make sure that they are the same variable/letter as well as to the same degree. The coefficient only affects the result. Because all of our variables are the same letter (x) and are all to the second degree, we can add them. To do this, we simply add the coefficients together to make one big coefficient, and multiply that by the variable. Thus,

4x² + 4x² + 4x² = (4+4+4)x² = 12x²

4x²+4x²+4x²  - 6 = 12x² - 6

Another way of looking at it is that 4x² = 4(x²) = x²+x²+x²+x²

Therefore, the expression to find the perimeter is 12x² - 6, and the perimeter when x= 1.5 is 12 * 1.5² - 6 = 21

A mathematical equation is a formula that joins two statements and indicates equality with the equal symbol (=). In algebra, an equation is a mathematical statement that establishes the equality of two mathematical expressions. In the equation 3x + 5 = 14, for example, the equal sign separates the variables 3x + 5 and 14. A mathematical formula describes the relationship between the two sentences on either side of a letter. There is frequently only one variable, which also serves as the symbol. For example, 2x - 4 = 2.

For a homogeneous system of linear equations, there are two possible outcomes: either there are several solutions or there is just one, trivial solution. There are three possible outcomes for a non-homogeneous system: either there is only one (unique) solution, several solutions, or no solutions at all.

In the given problem, the number of votes the winner got is 22. Also, the number of votes the second candidate got is 18.

Below is the step by step solution to the problem:

a) To get the amount of votes the winner got, we need form an equation based on the given information.

Let us suppose that the second candidate obtained x votes. According to the problem, the winner received four more votes than the runner-up. As a result, the winner received x + 4 votes.

Given that 40 students voted, the total number of votes cast for both candidates should be 40:

x + (x + 4) = 40

Simplifying the equation:

2x + 4 = 40

2x = 40 - 4

2x = 36

x = 36 / 2

x = 18

Therefore, the second candidate received 18 votes.

b) Now that we know the number of votes the second candidate received, we can get the number of votes the winner got:

Winner's votes = x + 4

Winner's votes = 18 + 4

Winner's votes = 22

So, the winner received 22 votes.

The revenue from student ticket sales can be calculated as 7.50s, and the revenue from adult ticket sales can be calculated as 10a.

To satisfy the constraint that the drama club must make no less than $1200, we can write the following inequality:

7.50s + 10a ≥ 1200

This inequality states that the total revenue from student ticket sales (7.50s) plus the total revenue from adult ticket sales (10a) must be greater than or equal to $1200.
