w varies directly as the square of x and inversely as p and q.

If w = 12 when x = 4, p = 2 and q = 20,

find w when x = 3, p= 8 and q = 5. b. 9 d. 5 21.​

Answers

Answer 1

The formula for this problem is: w = kx^2/(pq), where k is the constant of proportionality. To solve for k, we can substitute the given values of w, x, p, and q into the formula and solve for k. The value of w when x = 3, p = 8, and q = 5 is approximately 3.375.

12 = k(4^2)/(2*20)
12 = k(16/40)
12 = k(2/5)
k = (12*5)/2 = 30

Now that we know k, we can use the same formula to find w when x = 3, p = 8, and q = 5:

w = 30(3^2)/(8*5) = 27/4

To simplify this fraction, we can divide both the numerator and denominator by 1/4:

w = (27/4)/(1/4) = 27

Therefore, the answer is 27.


Given that w varies directly as the square of x and inversely as p and q, we can express this relationship using the equation:

w = k * (x^2) / (p * q)

where k is the constant of variation.

First, let's find the value of k using the given values w = 12, x = 4, p = 2, and q = 20:

12 = k * (4^2) / (2 * 20)

Now, solve for k:

k = 12 * (2 * 20) / (4^2)
k = 240 / 16
k = 15

Now that we have the value of k, we can find w when x = 3, p = 8, and q = 5:

w = 15 * (3^2) / (8 * 5)

w = 15 * 9 / 40
w = 135 / 40
w = 3.375

So, the value of w when x = 3, p = 8, and q = 5 is approximately 3.375.

What is the inverse of the statement?

A number that has exactly two distinct factors is prime.

If a number has exactly two distinct factors, then the number is prime.
If a number does not have exactly two distinct factors, then the number is not prime.
If a number is not prime, then the number does not have exactly two distinct factors.
If a number is prime, then the number has exactly two distinct fac

Answers

The inverse of the statement is "If a number does not have exactly two distinct factors, then the number is not prime." Thus Option 2 is the answer.

   When a conditional statement is reversed, the hypothesis and conclusion are both negated. The hypothesis in the original statement is "a number with exactly two distinct factors," while the conclusion is "is prime."

  To make the inverse, we negate both sections. "A number does not have exactly two distinct factors" is the antonym of "A number that has exactly two distinct factors." "Is not prime" is the opposite of "is prime."

    As a result, the inverse statement is "If a number does not have exactly two distinct factors, then the number is not prime."

     It's crucial to remember that a statement's inverse could or might not be accurate. In this instance, the inverse is true since the definition of a prime number is incompatible with the fact that a number has more than two components if it has more than exactly two different factors.

the ratio of men to women working for a company is to . if there are women working for the company, what is the total number of employees?

Answers

The given ratio of men to women working for the company is "to". Since the exact ratio is not provided, let's assume the ratio is "x:y". We are also given that there are "z" women working for the company.

To find the total number of employees, we need to determine the number of men working for the company.

Using the given ratio, we can set up the equation:
x/y = z/1

Cross-multiplying, we have:
x = z * y

Now, to find the total number of employees, we add the number of men and women:
Total employees = number of men + number of women
Total employees = x + z

Substituting the value of x from the equation above, we get:
Total employees = (z * y) + z

Simplifying the expression, we have:
Total employees = z * (y + 1)

In conclusion, the total number of employees in the company is z times the sum of the ratio (y+1).

Note: Since the exact ratio is not given, we cannot provide a numerical value for the total number of employees.

Answer:

x=-5

3x-12=9

3x=21

x=7

Answer:

1. \(x=-5\)

2. \(x=7\)

Step-by-step explanation:

First Equation

1. For the first equation, \(3x+10=-5\) we need to move all the constants to one side.

\(3x+10=-5\\3x=-15\)

2. Once that is done, we need to divide both sides by 3 to get \(x\) by itself.

\(3x=-15\\\frac{3x}{3}=\frac{-15}{3}\)

3. Now, we have our final answer.

\(x=-5\)

Second Equation

1. For the second equation, \(3x-12=9\) we need to move all the constants to one side.

\(3x-12=9\\3x=21\)

2. Once that is done, we need to divide both sides by 3 to get \(x\) by itself.

\(3x=21\\\frac{3x}{3} =\frac{21}{3}\)

3. Now, we have our final answer.

The probability that Steve chooses two different types of biscuits is 5/11 (or approximately 0.4545).

To calculate this, we need to consider the different combinations of two biscuits that Steve can take from the tin. There are two digestive biscuits, three chocolate biscuits, and seven ginger biscuits, so the total number of possible combinations is 12.

The number of combinations where he chooses two different types of biscuits is 5 (2 digestive and 1 chocolate, 2 digestive and 1 ginger, 1 chocolate and 1 ginger).

Therefore, any voting block which controls 51% of the votes will be able to elect all board members. Preemptive right [ Choose ] straight-line voting [ Choose ] cumulative voting

Answers

The correct matches are =

Proxy voting- Allowing someone else to vote one's shares

Board of Directors- the committee that hires, evaluates and monitors the senior managers of the firm

Preemptive right- The right to firstly buy any additional shares that the firm may issue before they are sold to the public

Straight-line voting- each candidate for the board of directors is elected by a majority vote

Cumulative voting- board seats are awarded in proportion to the votes received.

Definitions =

Proxy voting = Proxy voting is when a shareholder delegates their voting rights to another person or entity, known as a proxy, to vote on their behalf. This can be done for various reasons, such as when a shareholder is unable to attend a meeting or wants to entrust their voting decisions to someone else. It does not directly relate to board seats being awarded in proportion to the votes received.

Board of Directors = The Board of Directors is a group of individuals elected or appointed to represent the shareholders and oversee the management of a company. They are responsible for making major decisions, setting company policies, and appointing senior executives. Each candidate for the board of directors is typically elected by a majority vote of the shareholders.

Preemptive right = Preemptive right, also known as the right of first refusal, is a privilege granted to existing shareholders of a company. It allows them to have the first opportunity to purchase additional shares before they are offered to the public. This right helps protect the ownership interests of existing shareholders by giving them the chance to maintain their proportional ownership in the company.

Straight-line voting = Straight-line voting is not a commonly used term in corporate governance. However, based on the given options, it seems to be referring to a voting system where each shareholder is entitled to one vote per share they own. This is the standard method of voting in most corporate elections, where each shareholder's voting power is directly proportional to their shareholding.

Cumulative voting = Cumulative voting is a voting method that allows shareholders to pool their votes and allocate them as they see fit among the candidates for the board of directors. It gives minority shareholders the opportunity to concentrate their votes on fewer candidates and increase their chances of electing a representative to the board. This mechanism helps to ensure a more proportional representation of shareholders on the board.

Answers

Answer:

21 liters of the 12% solution and 4 liters of the 37% solution

Step-by-step explanation:

Represent the number of liters of the first solution as x and the second as y. Now, the total liters of iodine is going to be 16% of 25 = 4 liters of iodine, and the total liters of each solution is going to be 25. Now, we can setup two equations:

0.12x+0.37y = 4

x + y = 25

Multiplying the bottom equation by 0.12, we have

0.12x + 0.12y = 3

Subtracting, we have

0.12x+0.37y=4

-

0.12x + 0.12y = 3
