in 3x + 2/3y - 15 < 0, the point (x,9) is a solution for the inequality shown. what is the possible value for x?

a: 2

b: 3

c: 4

d: 5

Answer:

x=55, and y=62.5

Step-by-step explanation:

The reason why x=55 is because x and the angle 125 degrees form a linear pair (180 degrees) Hence,

x+125=180

=> x=180-125

=> x=55

Now coming to y, As we see y and 125 do not form a linear pair, so we know that x=the top angle of the triangle in which angle y is there. And with the information we also find that the triangle in which y is present is an isosceles triangle, so the other 2 angle  than the top angle are equal, which are y and another angle which is also y as they are the same degrees. Hence, we know x=55, then,

55+2y=180(As the angles in a triangle sum up to 180 degrees)  

=> 2y=180-55

=> 2y=125

=> y=125/2

=> y=62.5

Hope my answer helps, Thank you!

You have $2.30 and would like to buy some rice flour buy 9.2 ounces of rice flour with $2.30.

To arrive at this answer, we need to first convert the price per pound to price per ounce. There are 16 ounces in a pound, so the price per ounce is $4/16 = $0.25 per ounce.

Next, we divide the amount of money you have ($2.30) by the price per ounce ($0.25).

$2.30/$0.25 = 9.2 ounces.

Therefore, the conclusion is that you can buy 9.2 ounces of rice flour with $2.30.
Hi! I'm happy to help you with your question.


You can buy 9.2 ounces of rice flour.


1. First, we need to find out how many dollars you have per ounce of rice flour: $4 per pound / 16 ounces per pound = $0.25 per ounce.
2. Next, we'll determine how many ounces of rice flour you can buy with $2.30: $2.30 / $0.25 per ounce = 9.2 ounces.


With $2.30, you can buy 9.2 ounces of rice flour at the given price of $4 per pound.

Fallacies of relevance are types of logical fallacies that occur when an argument is presented without a relevant connection to the subject matter.

Rather than addressing the topic, these fallacies are aimed at the listener's feelings, emotions, or biases.There are many different types of fallacies of relevance, but some of the most common are ad hominem, straw man, appeal to authority, and red herring. Ad hominem, for example, is a type of fallacy that attacks the speaker rather than addressing the argument they are presenting.. It can undermine the quality of your argument and make you seem less credible.

However, if you want to describe a time when you used these fallacies, you might think back to a situation where you were arguing with someone and felt like you were losing the argument. In this case, you might have resorted to a fallacy of relevance to try to regain control of the conversation. In conclusion, it is important to avoid using fallacies of relevance in your arguments. Instead, focus on addressing the topic at hand and presenting logical, evidence-based arguments.

The largest angle is $5^{th}$ angle which has a measure of $179.33$ degrees.

In a convex pentagon, the sum of all interior angles is equal to 540 degrees. Therefore, we can write the following equation:
$$x+2x+3x+4x+5x-1=540$$
Simplifying the equation, we get:
$$15x-1=540$$
$$15x=541$$
$$x=36.07$$
Now that we know the value of x, we can find the measure of each angle:
$1^{st}$ angle: $x=36.07$ degrees
$2^{nd}$ angle: $2x=72.14$ degrees
$3^{rd}$ angle: $3x=108.21$ degrees
$4^{th}$ angle: $4x=144.28$ degrees
$5^{th}$ angle: $5x-1=179.33$ degrees

Therefore, the largest angle is $5^{th}$ angle which has a measure of $179.33$ degrees.

To calculate the future value of RM100 deposited today in five years with an interest rate of 12% per year, we can use the formula for compound interest: Future Value = Principal × (1 + Interest Rate)^Time In this case, the principal (P) is RM100, the interest rate (r) is 12% (or 0.12 in decimal form), and the time (t) is five years.

Plugging in these values into the formula, we get:

Future Value = RM100 × (1 + 0.12)^5

Simplifying the expression:

Future Value = RM100 × (1.12)^5

Calculating the exponent:

Future Value = RM100 × 1.7623

Multiplying:

Future Value = RM176.23

Therefore, the future value of RM100 deposited today in five years with a 12% interest rate per year is approximately RM176.23.

In order to find a critical value (maximum or minimum) we need to compute the first derivative, which is given by

Then, a critical value ocurrs when

which implies that

So by adding 6 to both side, we have

Therefore, there is a maximum or minimum at x=1.

In order to see if the point represents a maximum or minimum, we need to find the second derivative of our function, which is given by

We have that if the second derivative is positive, the point represents a minimum and if it is negative, the point represents a maximum. In our case, since the second derivative is greater than zero (positive number) there is a minimum point at x=1. Then, by substituting this values into the function, we get

so the minimum point is located at (1,2).

where the symbol on the right, between A and B, is the intersection, which can be understood as "and". Since we are going to pick only one person, it is impossible that we pick an adult chaperona and a male student. So,

So we have

Now, we want to calculate P(A) and P(B).

To calculate the probability of each event, we first count the number of possibilities that the event is true.

Note that since we have 6 adult chaperones, we have 6 possibilites such that the event A is true. Now, to calculate the probability of A, we simply divide this number by the total number of people on the bus (which is 50). So we get

In the same manner, for event B, we have a total of 23 possibilities such that the event B is true. Then

If a nonhomogeneous system of linear equations is underdetermined, it can have either infinitely many solutions or no solutions.

A nonhomogeneous system of linear equations is represented by the equation Ax = b, where A is the coefficient matrix, x is the vector of unknowns, and b is the vector of constants. When the system is underdetermined, it means that there are more unknown variables than equations, resulting in an infinite number of possible solutions. In this case, there are infinitely many ways to assign values to the free variables, which leads to different solutions.

To determine if the system has a solution or infinitely many solutions, we can use techniques such as row reduction or matrix methods like the inverse or pseudoinverse. If the coefficient matrix A is full rank (i.e., all its rows are linearly independent), and the augmented matrix [A | b] also has full rank, then the system has a unique solution. However, if the rank of A is less than the rank of [A | b], the system is underdetermined and can have infinitely many solutions. This occurs when there are redundant equations or when the equations are dependent on each other, allowing for multiple valid solutions.

On the other hand, it is also possible for an underdetermined system to have no solutions. This happens when the equations are inconsistent or contradictory, leading to an impossibility of finding a solution that satisfies all the equations simultaneously. Inconsistent equations can arise when there is a contradiction between the constraints imposed by different equations, resulting in an empty solution set.

In summary, when a nonhomogeneous system of linear equations is underdetermined, it can have infinitely many solutions or no solutions at all, depending on the relationship between the equations and the number of unknowns.

The range is the difference between the highest and the lowest value of a set, so it is sensitive to extreme values. That is, you can have two sets with the same mean, but with very different spacings.

For example, two grades:

set A = {40, 50, 50, 60}

set B = {0, 50, 50, 100}

The set B has a way higher range(100) than set A(20), that is, the range is sensitive to extreme values.

the equation for the level surface passing through the point (3, 0, 1) is x + 2y - 3z = 0. The given function is f(x, y, z) = (x - y + 2z) / (2x + y - z). We are asked to find an equation for the level surface passing through the point (3, 0, 1).

To find the equation for the level surface, we need to set the function equal to a constant value and solve for z.

Let's start by substituting the coordinates of the given point into the function:

f(3, 0, 1) = (3 - 0 + 2(1)) / (2(3) + 0 - 1)
           = 5 / 5
           = 1

So, the constant value for the level surface passing through (3, 0, 1) is 1.

Now, let's set the function equal to 1 and solve for z:

1 = (x - y + 2z) / (2x + y - z)

Cross-multiplying, we get:

2x + y - z = x - y + 2z

Rearranging the terms, we have:

x + 2y - 3z = 0

Therefore, the equation for the level surface passing through the point (3, 0, 1) is x + 2y - 3z = 0.

In summary, the equation for the level surface passing through the point (3, 0, 1) is x + 2y - 3z = 0.
