The sequence of the other length of the rectangles is represented by the equation: an=8+(n−1)4 a) Determine two side lengths of the tenth rectangle in the sequence. b) You are given the following areas of rectangles: 392in2, 128in2, 576in2, and 968in2 Determine which of the areas is not possible in the given sequence and explain why.

The answer to the question can be calculated by using the average formula.

The average of a set of numbers is calculated by adding all of the numbers together and dividing the sum by the number of numbers in the set. In this case, the five alepeople earned a total of $176,506, and when divided by 5, the average annual income comes to $35,516.

To calculate the fifth aleperson's income, we subtract the income of the first four alepeople from the total income earned, $176,506. Subtracting the income of the first four alepeople, $36,230 + $34,500 + $38,250 + $33,000, gives us a remaining total of $24,026. When we divide this remaining total by 1, the average annual income for the fifth aleperson comes to $24,026.

Therefore, the fifth aleperson earned an annual income of $24,026. This can be expressed using the formula (total income – (income of aleperson 1 + income of aleperson 2 + income of aleperson 3 + income of aleperson 4)) / number of alepeople = income of fifth aleperson. In this case, (176,506 – (36,230 + 34,500 + 38,250 + 33,000)) / 1 = 24,026.

What is Linear system of inequality?

At least two linear inequalities in the same variables make up a system of linear inequality in two variables. The graph of a linear inequality is the graph of all solutions to the system, and the solution of a linear inequality is the ordered pair that resolves all inequalities in the system.

With the exception of the inequality symbol, a linear inequality is nearly identical to a linear equation.

The probability of not finding purple jar is 0.8.

Firstly we will find the probability of drawing purple marble. The formula to be used for this is -

Probability = number of favourable outcomes ÷ total number of outcomes

Number of favourable outcomes = number of purple marbles

Total number of outcomes = sum of the number of marbles

Total number of outcomes = 22 + 26 + 17 + 20

Performing addition

Total number of outcomes = 85

Probability = 20/85

Performing division

Probability = 0.2

Probability of not finding purple = 1 - probability of finding purple

Probability of not finding purple = 1 - 0.2

Answer: The correct inequality that matches the graph is 6x + y < 3.

This inequality can be graphed by plotting the points (0,3) and (1,9) as the boundary of the solution set, and shading the area above the line. The graph will be a line with a negative slope that pass through the points (0,3) and (1,9) and the shaded area will be above the line, which match the graph you have described.

We can check this by plugging the points (0,3) and (1,9) into the inequality to see if they satisfy it:

6(0) + 3 < 3 => 3 < 3 which is true

6(1) + 9 < 3 => 6 + 9 < 3 which is false

This confirms that the inequality 6x + y < 3 matches the graph.

Triangle ABC is the preimage and triangle A'B'C' is the image. The equation for the line of reflection is x = 4.

Reflection is a type of geometric transformation where the figure is flipped. In other words, a figure when undergoes reflection becomes it's mirror image.

(A) Pre image is the figure before reflection is done.

So the pre image is triangle ABC.

(B) Image is the reflected figure.

So the image is triangle A'B'C'.

(C) Coordinates of the output are :

A'(8, 9), B'(12, 4) and C'(8, 4)

(D) The line of the reflection is the parallel line to Y axis passing through 4 on the X axis.

So the equation is x = 4.

Hence triangles ABC and A'B'C' are preimage and image respectively. The coordinates for the output are A'(8, 9), B'(12, 4) and C'(8, 4).

The greatest possible length of a side of a triangle whose perimeter is 1000 and all of whose sides have integral lengths is 400.

We have to determine the greatest possible length of a side of a triangle whose perimeter is 1000 and all of whose sides have integral lengths.

The sides of a triangle have lengths ratio 5:7:8.

The perimeter of triangle is the sum of all sides. So

5x + 7x + 8x = 1000

20x = 1000

Divide by 20 on side we get

x = 50

The length of all sides:

5x = 5 × 50 = 250

7x = 7 × 50 = 350

8x = 8 × 50 = 400

The answer set of an inequality is expressed in mathematics using a set builder notation. For instance, the set builder notation is understood to mean the collection of all y, where y is bigger than 0.

Mathematical expressions with inequalities are those in which the two sides are not equal. Contrary to equations, we compare two values in inequality. Less than, larger than, or not equal to signs are used in place of the equal sign.

The given inequality is:

b + 2 ≥ 4

Subtract 2 on both sides of the equation:

We have,

125° and (109° + ∠N) are alternate angles.

Alternate angles are equal.

125 = 109 + ∠N

∠N = 125 - 109

∠N = 16

Now,

The sum of the triangle ABC is 180.

∠P + ∠M + ∠N = 180

Sides opposite to equal angles are equal.

∠P = ∠M

2∠P + 16 = 180

2∠P = 180 - 16

Speed is calculated by dividing distance by time. Here Sam is cycling at a speed of 15 km/h and Dwight at a speed of 12km/h. So Sam cycles faster.

Speed is the rate of change in distance. so it is calculated using distance/time. Here the distance is in km and time is in minutes. The unit of distance is either m/s or km/h. So we have to do conversions first.

Lets convert the minutes to hours.

Sam cycles for 20 minutes. So 20 min = 20/60 h = 0.33 h

Dwight cycles 30 minutes. So 30 min = 30/60 h = 0.5 h

Now lets calculate the speed.

Speed Sam cycles = 5 km/ 0.33 h = 15 km/h

Speed Dwight cycles = 6 km/0.5 h = 12 km/h.

So Sam is faster than Dwight.

Answer: To solve the equation 2X = X + 5, we can start by isolating X on one side of the equation by subtracting X from both sides:

2X - X = X + 5 - X

Therefore, X = 5 is the solution of the equation 2X = X + 5.

Step-by-step explanation:

The solution for x in the equation 2x = x + 5 is obtained by isolating the variable x, leading to the answer x = 5.

To solve for x in the equation 2x = x + 5, you need to isolate x. Start by subtracting x from both sides of the equation to get 2x - x = x + 5 - x which simplifies to x = 5.
