The area of the circle would be 36π.

What is the area of a circle?

If the circle has a radius then the area of the circle can be computed by using the formula

area = π * radius²

The perimeter of the square = 24

4 * side = 24

Side of a square = 24/4 = 6

Side of a square = radius of the circle

Substituting the radius of 6 into this formula gives:

area = π * 6²

Which simplifies to:

area = π * 36

Hence, the area of the circle would be 36π.

The inequality is [tex]115\leq x\leq 495[/tex]

What is inequality?

A connection is termed an inequality if two real numbers or algebraic expressions are connected by the symbols ">", "<", "≥". Inequality is a mathematical statement that uses the inequality symbol to illustrate the relationship between two expressions. An inequality symbol has non-equal expressions on both sides. It indicates that the phrase on the left should be bigger or smaller than the expression on the right, or vice versa. Literal inequalities are relationships between two algebraic expressions that are expressed using the inequality symbols.

V = 20,000 * 0.81^2 and V = 20,000 * (1 - 0.19)^2 are the equation(s) that represent the exponential relationship.

The value of the car two years later is represented by the variable V. The initial value of the car is represented by the constant 20,000. The relationship between the value of the car two years later and the initial value of the car is exponential, because the value of the car decreases by a fixed percentage each year.

One equation that represents this relationship is:

V = 20,000 * 0.81^2

This equation says that the value of the car two years later is equal to the initial value of the car multiplied by the decay factor of 0.81 raised to the power of 2. The decay factor represents the percentage by which the value of the car decreases each year.

Another equation that represents this relationship is:

V = 20,000 * (1 - 0.19)^2

This equation says that the value of the car two years later is equal to the initial value of the car multiplied by (1 - 0.19) raised to the power of 2. The term (1 - 0.19) represents the percentage by which the value of the car remains after it has depreciated.

Both of these equations represent the exponential relationship between the value of the car two years later and the initial value of the car.

The probability that the next person who leaves the lecture will have gray hair is 45/163 or 0.2760.

What is Probability?

Probability is the ratio of favorable outcomes to all other potential outcomes of an event. The number of positive results for an experiment with 'n' outcomes can be represented by the symbol x. The probability of an event can be calculated using the following formula.

Probability(Event) = Positive Results/Total Results = x/n

To calculate the likelihood that the next person to leave the lecture will have grey hair, one must first make an assumption about the distribution of hair colors among those in attendance. The data of the distribution of hair colors of people in the lecture are assumed below:

Blonde  Red  Brown  Black   Gray  Total

24           32     29        33        45     163

The Probability of the number of people with grey hair to the total number of students in the class is used to calculate the likelihood that the next person to leave the lecture will have grey hair.

P(Gray) =45÷163 =0.2760

So therefore, the probability is 45/163 or 0.2760.

Answer: 0.85

Step-by-step explanation:

The required answer for long division for the decimal division of 6 divided by 7.02 is 0.8547 by rounded to four decimal places.

To perform long division for the decimal division of 6 divided by 7.02, follow these steps:

Step 1: Set up the division problem:

_______

7.02 | 6.00

Step 2: Place the decimal point directly above the division bar in the quotient:

0.

Step 3: Divide the first digit of the dividend (6) by the divisor (7.02). The result is 0.8547 (rounded to four decimal places).

Step 4: Multiply the divisor (7.02) by the quotient digit (0.8547) and write the result below the dividend, aligning the decimal points:

7.02

- 6.03

-----

0.99

Step 5: Subtract the result from the previous step from the dividend, and bring down the next digit (if any):

0.99

- 0.99

-----

0.00

Step 6: Since there are no more digits to bring down and the result is zero, we can conclude the division.

Therefore, the long division for the decimal division of 6 divided by 7.02 is 0.8547(rounded to four decimal places).

What is the value of X triangle?

The two angles' combined angles are subtracted from 180 degrees. A triangle's total angles are always equal to 180 degrees. When you remove the total of the two angles from 180 degrees, note the difference you discovered. This is what X is worth. The algebraic expression should often take one of the following forms: addition, subtraction, multiplication, or division. Bring the variable to the left and the remaining values to the right to determine the value of x. To determine the outcome, simplify the values.

Remove parentheses: (a)=a

9 x+1+88=180

The translation of triangle MNP along T < 2 , -9 > is

What is Translation?

A translation moves a shape up, down, or from side to side, but it has no effect on its appearance. A transformation is an example of translation. A transformation is a method of changing a shape's size or position. Every point in the shape is translated in the same direction by the same amount.

The notation for translation is T(h, k) where T is the translation, h is the change in the x-axis, and k is the change in the y-axis

Given data ,

Let the translated triangle be represented as ΔM'N'P'

Now , the translation rule is T < 2 , -9 >

Let the coordinates of the triangle ΔMNP be

The coordinates of M = M ( -3 , 7 )

The coordinates of N = N ( 0 , 4 )

The coordinates of P = P ( 2 , 6 )

Now , applying the translation rule of T < 2 , -9 > for the triangle MNP , we get

The coordinates of M' = M' ( -3 + 2 , 7 - 9 )

The coordinates of M' = M' ( -1 , -2 )

The coordinates of N' = N' ( 0 + 2 , 4 - 9 )

The coordinates of N' = N' ( 2 , -5 )

The coordinates of P' = P' ( 2 + 2 , 6 - 9 )

The coordinates of P' = P' ( 4 , -3 )

Hence , the coordinates of triangle M'N'P' is M’(−1, −2), N’(2, −5), P’(4, −3)
