What is the area of this tile?
And it isn’t 12 because I did that for the other one and got it wrong.

By simplifying the given square root , we get Simplified Root : 6 xz • [tex]\sqrt{(2xz) }[/tex]

Factor 72 into its prime factors

          72 = 23 • 32

To simplify a square root, we extract factors which are squares, i.e., factors that are raised to an even exponent.

Factors which will be extracted are :

          36 = 22 • 32

Factors which will remain inside the root are :

          2 = 2

To complete this part of the simplification we take the square root of the factors which are to be extracted. We do this by dividing their exponents by 2 :

          6 = 2 • 3

At the end of this step the partly simplified square root looks like this:

        6 • [tex]\sqrt{ (2x3z3) }[/tex]

Simplify the Variable part of the square root

Rules for simplifing variables which may be raised to a power:

  (1) variables with no exponent stay inside the radical

  (2) variables raised to power 1 or (-1) stay inside the radical

  (3) variables raised to an even exponent: Half the exponent taken out, nothing remains inside the radical. examples:

   [tex]\sqrt{(x8)}[/tex]=x4

 [tex]\sqrt{ (x^6)}[/tex]=x-3

   (4) variables raised to an odd exponent which is  >2  or  <(-2) , examples:

   [tex]\sqrt{ (x5)}[/tex]=x2•[tex]\sqrt{x}[/tex]

  [tex]\sqrt{ (x^7)}[/tex]=x-3•[tex]\sqrt{x}[/tex]

Applying these rules to our case we find out that

[tex]\sqrt{ (x3z3)}[/tex] = xz • [tex]\sqrt{(xz) }[/tex]

Combine both simplifications

      [tex]\sqrt{ (72x3z3)}[/tex] = 6 xz •[tex]\sqrt{(2xz) }[/tex]

The mass of the watermelons is 24 kg and the mass of the mangoes is 8 kg.

A physical quantity is mass. The unit of mass measurement is the body's weight. Normal mass units like grammes, kilogrammes, and pounds can be used to measure it.

We are informed of the following:

T + W = 27 (total mass of trolley and watermelons is 27 kg)

T + M = 11 (total mass of trolley and mangoes is 11 kg)

W = 3M (mass of watermelons is three times the mass of mangoes)

Elimination or substitution can be used to solve this set of equations. Substitutions made

We can enter W = 3M into the first equation in place of the third equation to obtain:

T + 3M = 27

From the second equation, we can substitute T = 11 - M into this equation to get:

(11 - M) + 3M = 27

Simplifying this equation, we get:

2M = 16

So, M = 8 kg. This means that the mass of the mangoes is 8 kg.

We can substitute this value of M back into the second equation to get:

T + 8 = 11

So, T = 3 kg. This means that the mass of the trolley is 3 kg.

Finally, we can substitute these values of T and M into the first equation to get:

3 + W = 27

So, W = 24 kg. This means that the mass of the watermelons is 24 kg.

The simplified form of the expression (⅓m - 2/x) ÷ (9-y²) ÷ (2x²m-12x) ÷ (9x+3xy) is (x-3m)/(4mx (mx-6) (3-y)).

Mathematical expression is a mathematical statement involving numerical values, mathematical operations, variables, power of variables and combination of that.

The expression is = (⅓m-2/x)÷(9-y²) ÷(2x²m-12x)÷(9x+3xy)

We have to simplify the expression.

Simplifying the expression we get,

(1/3m - 2/x) ÷ (9 -y²) ÷ (2x²m -12x) ÷ (9x +3xy)

= ((x-3m) / 6mx)*(1 / (3²-y²)) ÷ ((2x (mx-6)) / (3x (3+y)))

= ((x-3m) / 6mx (3+y) (3-y)) * (3x (3+y) /2x (mx-6)) [Since, a²- b² = (a+b)(a-b)]

Therefore, the solution to the system of equations is: x = 13/12, y = -3/4 that is option C.

In mathematics, an equation is a statement that asserts the equality of two expressions, separated by an equals sign (=). The expressions on either side of the equals sign are referred to as the left-hand side (LHS) and the right-hand side (RHS) of the equation. Equations are used to describe relationships between variables and to solve problems.

Here,

To solve the system of equations:

4y + 12x = 10 ...(1)

2y - 6x = -8 ...(2)

We can use the method of elimination or substitution.

Method of elimination:

We can eliminate x by multiplying equation (2) by 2 and adding it to equation (1) to obtain:

4y + 12x = 10

(4y - 12x = -16)

8y = -6

Dividing both sides by 8, we get:

y = -6/8

y = -3/4

Substituting this value of y in equation (1), we get:

4(-3/4) + 12x = 10

Simplifying and solving for x, we get:

-3 + 12x = 10

12x = 13

x = 13/12

only the equation y=1/x shows an indirect proportional relationship, while the other three equations show either a direct proportional or a linear relationship.

How to solve the question?

The mathematical term "indirectly proportional" refers to a relationship in which two variables are related in such a way that when one increases, the other decreases, and vice versa. In other words, the two variables vary in opposite directions.

Out of the four equations given, only one shows an indirect proportional relationship. This equation is:

y=1/x

In this equation, y and x are indirectly proportional. As x increases, the value of 1/x decreases, and therefore, the value of y decreases as well. Similarly, as x decreases, the value of 1/x increases, and the value of y increases as well. This relationship is commonly known as an inverse relationship, where the two variables vary in opposite directions.

On the other hand, the other three equations do not show an indirect proportional relationship. The equation y=5x shows a direct proportional relationship, where y increases as x increases and vice versa. The equation y=-2x+1 is a linear equation with a negative slope, where y decreases as x increases, and y increases as x decreases. Lastly, the equation y=3x+5 is also a linear equation with a positive slope, where y increases as x increases, and y decreases as x decreases.

In summary, only the equation y=1/x shows an indirect proportional relationship, while the other three equations show either a direct proportional or a linear relationship.

The probability of rolling an even number on a dice is 1/2, since there are three even numbers (2, 4, and 6) out of a total of six possible outcomes (1, 2, 3, 4, 5, and 6).

The probability of landing on tails when flipping a coin is also 1/2, since there are only two possible outcomes (heads or tails) and they are equally likely.

To find the probability of both events happening together, we need to multiply their probabilities:

1/2 (probability of rolling an even number) x 1/2 (probability of landing on tails) = 1/4

Therefore, the probability of rolling an even number on a dice and landing on tails when flipping a coin is 1/4 or 0.25 (25%).

Yes, it is possible for the range of a data set of positive data values to be less than the mean of that data set.

The range of a data set is the difference between the maximum and minimum values in the data set, while the mean (also known as the average) of a data set is the sum of all the values divided by the total number of values.

For example, consider the following data set of positive values: {2, 3, 5, 7, 9}. The range of this data set is 9 - 2 = 7, while the mean is (2 + 3 + 5 + 7 + 9)/5 = 26/5 = 5.2. In this case, the range (7) is less than the mean (5.2).

This can occur when the data set has a relatively small range, meaning that the difference between the maximum and minimum values is not very large compared to the mean.

the distribution of the data set and the specific values within it can affect the relationship between the range and the mean.

It's important to note that range and mean are just two measures of central tendency and variability, and other measures such as median, mode, and standard deviation can provide additional insights into the characteristics of a data set.
