Note that the scale and actual area are matched as follows;

To find the area of the scale drawing, you can use the following formula:

Scale Drawing Area = (Actual Area) x (Scale Ratio)²

Let's take the first for example.

We have the Actual Area to be 147; and

Scale Ratio to be 1 inch to 7 feet. That is 1/7

Thus,

Scale Drawing Area = 147 x (1/7)²

Scale Drawing Area = 147 x 0.02040816326  ; thus

Scale Drawing Area = 3

Thus, where you have:

147 square feet is equivalent to 3 square inches when using a scale of 1 inch to 7 feet.

Repeat the above process for each of the other categories.

In the given situation there are 144 possible ways for the nine representatives at the table.

We will first determine how many different options there are to seat the delegates of the three nations at the table.

We can arrange the three delegates we have for England in 3! = 6 different ways.

We can arrange the four delegates we have for Germany in 4! = 24 different ways.

We can organize the two representatives we have for France in 2! = 2 different ways.

The total number of arrangements for all nine delegates is obtained by multiplying the number of arrangements for each country's representatives.

6 x 24 x 2 = 288 ways

However, because the table is round, two configurations are deemed identical if they can both be created by rotating one.

To put it another way, the configurations are identical to one another and are not counted individually.

The total number of configurations divided by the number of identical arrangements gives the number of ways to position all nine representatives around the table (also known as rotations).

288 / 2 = 144

The nine representatives can be seated at the table in 144 different ways.

Because 144 is an even number, it should be noted that there are actually twice as many possible methods to solve the problem (144 x 2 = 288), or 540 options.

Therefore, in the given situation there are 144 possible configurations for the nine representatives at the table.

Complete question:
An international meeting is held between england, Germany, and france. three representatives attend from England, four from germany, and two from france. how many ways can all nine representatives sit around a circular table, if representatives of the same country sit together? (two ways are considered the same if one can be rotated to produce the other.)

On solving the provided question, we can say that - the perimeter chest won't fit next to her bed, thus the answer is no.

The perimeter of a form is determined by the length of its contour. A rectangle or square's perimeter is determined by adding the widths of its four sides. In this instance, the rectangle's length and breadth are represented by x and y, respectively. The surface of a form is used to compute its area.

Given here is: In her room, it is 86 inches wide. The width of the bed is 76 inches.

She also wants to accommodate a chest of drawers that is 72 centimeters broad, which equals inches.

=> 90 cm = 24.6546536565 inches

and the space left in her room = 86-76=10 inches

thus, the chest will not fit next to her bed

The required value of c is c = 1.407 which satisfies the Mean Value Theorem.

The Mean Value Theorem states that if a function f is continuous on a closed interval [a,b] and differentiable on the open interval (a,b), then there exists a point c in the interval (a,b) such that f'(c) = (f(b) - f(a))/(b-a).

As per the given question, [tex]f(x) = (5x-10)^{2/3}[/tex], a=0, and b=2.

To find the values of c that satisfy the Mean Value Theorem, we need to find the derivative of f(x) and then solve the equation f'(c) = (f(2) - f(0))/(2-0) for c.

The derivative of f(x) is f'(x) = 5 × (2/3) [tex]\dfrac{1}{(5x-10)^{1/3}}[/tex]  = (10/3) × [tex]\dfrac{1}{(5c-10)^{1/3}}[/tex]

Substituting this into the equation above, we get

(10/3) × [tex]\dfrac{1}{(5c-10)^{1/3}}[/tex] =  [tex]\dfrac{0 - 10^{2/3}}{2-0}[/tex]

(10/3) × [tex]\dfrac{1}{(5c-10)^{1/3}}[/tex] = [tex]-\dfrac{10^{2/3}}{2}[/tex]

Solving this equation for c, we find that c =38/27≈ 1.407.

Thus, the value of c that satisfies the Mean Value Theorem is c = 1.407.

The scale factor is 8 : 1 ( option A)

A scale factor is defined as the ratio between the scale of a given original object and a new object, which is its representation but of a different size (bigger or smaller). For example, if we have a rectangle of sides 2 cm and 4 cm, we can enlarge it by multiplying each side by a number, say 2. The new sides will be 4cm and 8cm. Therefore the scale factor is 2

To calculate scale factor we divide the new shape size by original shape .

The new shape is 24m and the original shape is 3m.

scale factor = 24m/3m = 8/1

therefore scale factor = 8 : 1

This equation has no solution

To solve this problem, you will need to use the rules of complex numbers to multiply and simplify the given expressions.

First, let's simplify each of the given expressions:

(a+ib) (3 + 4i ) = a3 + a4i + ib3 + ib4i

= (3a - 4b) + (4a + 3b)i

(2 + i ) (2- i ) = (2*2) + (2(-1))i + (1*2) + (1(-1))i

= (4 - 1) + (2 - 1)i

= 3 + i

Now, we can set the two expressions equal to each other and solve for a and b:

(3a - 4b) + (4a + 3b)i = 3 + i

3a - 4b = 3

4a + 3b = 1

We can solve this system of equations using any method you prefer, such as substitution or elimination. One way to solve this system is to eliminate one of the variables by multiplying the first equation by 4 and the second equation by -3:

12a - 16b = 12

-12a - 9b = -3

This simplifies to:

0 = 9

This equation has no solution, so the original expression cannot be true. This means that a²+b² is not defined in this case.

A straight line can be written in the slope-intercept form as, y = mx + c.

In order to obtain the slope, the ratio of the difference of the coordinates are taken and c is the y-intercept which can be found by substituting x = 0 in the equation.

The  equation of the lines given in the graph can be written as,

(4) Slope of the line is m = (3 - 0)/(0 - 6)

⇒ m = -0.5

And, y-intercept is 3

Then, the slope-intercept equation can be written as y = -0.5x + 3.

(5) Slope of the line is m = (1 - (-4))/(0 - (-2))

⇒ m = 5/2 =2.5

And, the y-intercept is 1.

Then, the slope-intercept equation can be written as y = 2.5x + 1.

(6) Slope of the line is m = (-5 - 3)/(0 - (-2)) = -4

And, the y-intercept is -5.

Then, the slope-intercept equation can be written as y = -4x - 5.

(7) Slope of the line is m = (2 - 0)/(0 - 2) = -1.

And, the y-intercept is 2.

Then, the slope-intercept equation can be written as y = -x + 2

(8) Slope of the line is m = (-4 - 0)/(0 - 6) = 2/3

And, the y-intercept is -4.

Then, the slope-intercept equation can be written as y = 2/3x - 4.

(9) Slope of the line is m = (6 - 0)/(6 - 0) = 1.

And, the y-intercept is 0.

Then, the slope-intercept equation can be written as y = x.

Hence, the equations of the lines can be obtained as y = -0.5x + 3, y = 2.5x + 1, y = -4x - 5, y = -x + 2, y = 2/3x - 4 and y = x.
