Answer:

$54.65 profit per seat

Step-by-step explanation:

150(185) + 35(185)(.8) = 27,750 + 5,180 = 32,930 - 22,000 = 10,930

10,930/200 = $54.65 profit per seat

Answer:

$54.65

Step-by-step explanation:

First, we find the total amount made. This is easy:

(150 x 185) + (35 x .8(185)) =

27750 + 5180 =

32930

We then subtract the $22000, so the company makes a profit of 10930. There are 200 seats, so the profit made per seat is $54.65

The MATLAB code to solve the partial fraction expansion for the given system, So the answer is: c_t = ilaplace(C, s, t);

Matlab          Code

[ syms s t

X = 10 / (s*(s-2)*(s+3));

[r, p, k] = residue(10, [1, -2, 3]);

C = r(1)/ (s-p(1)) + r(2) / (s-p(2)) + r(3) / (s-p(3));

c_t = ilaplace(C, s, t);

disp('Solution for c(t):');

disp(c_t);

]

In the above code, we first define the transfer function X (C(s)) using the symbolic variable 's'. Then, we use the 'residue' function to obtain the partial fraction expansion, with the numerator '10' and the denominator '[1, -2, 3]'. The outputs 'r', 'p', and 'k' represent the residues, poles, and direct term (if any).

Next, we construct the partial fraction expansion 'C(s)' using the obtained residues and poles. Finally, we use the ' ilaplace' function to perform the inverse Laplace transform and obtain the solution for c(t). The result is displayed using 'disp'.

Answer:

2:3

Step-by-step explanation:

9marbles - redmarbles=6marbles

6/9

To simplify the ratio 6:9, we find the greatest common divisor of 6 and 9, and then we divide 6 and 9 by the greatest common divisor. The greatest common divisor that you can use to simplify 6:9 is 3. Which means the answer to ratio 6:9 simplified is: 2:3. Here is the math to illustrate better: 6/3 = 2 and 9/3 = 3.

Answer:

2 : 4

green : blue

Step-by-step explanation:

if there is 9 marbles in the bag and 3 are red and 2 are green then 3+2= 5 so 9-5 = 4 so there 4 blue marbles

The given points H, I, J, and K form a parallelogram.

The slopes of the sides can be calculated using the formula:

Slope = (change in y) / (change in x)

Slope of side HI:

= (1 - (-2)) / (7 - 4) = 3 / 3 = 1

Slope of side IJ:

= (4 - 1) / (4 - 7) = 3 / (-3) = -1

Slope of side JK:

= (1 - 4) / (1 - 4) = (-3) / (-3) = 1

Slope of side KH:

= (-2 - 1) / (4 - 1) = (-3) / 3 = -1

Now, let's calculate the lengths of the sides:

Length of side HI:

= √(7-4)² + (1+2)²

= √9 + 9

= √18

Length of side IJ:

= √(4-4)² + (4-1)²

= √0+ 9

= √9

=3

Length of side JK:

= √(4-1)² + (4-1)²

= √9 + 9

= √18

Length of side KH:

= √(4-1)² + (-2-1)²

= √9 + 9

= √18

Based on the slopes and lengths, we can identify the type of quadrilateral: The given points H, I, J, and K form a parallelogram.

Answer: Using the triangle theorem, the angle (64 + x)° and 110° are alternate angles, therefore the angle marked, x is 46°

Step-by-step explanation: Alternate angles are equals :

(64 + x)° = 110°

We can solve for x thus ;

x + 64 = 110

x + 64 - 64 = 110 - 64

x = 46°

Hence, the value of x in the triangle is 46°

Answer:

the triangle is a right angle triangle. I can't see the correct explanation here so I will explain

Step-by-step explanation:

to work out whether triangles are right angle you do :

square root of (5² + 12²) so it would be 25 + 144 =169 and the square root of 169 is 13 . we do this because the square root of both of the side lengths squares should make ths longer side in this case it makes 13 so it is a right angled triangled

The scale factor is: 5/3.5 ≈ 1.43

The value of x = 12.

The scale factor is a numerical value used to describe the proportional relationship between two similar objects or figures. It is the ratio of the length of a corresponding side in one figure to the length of the same side in the other figure.

Thus, Scale factor = Dimension of the new shape ÷ Corresponding Dimension of the original shape

Therefore, we have:

Scale factor = J'H" / JH

= 5/3.5 ≈ 1.43

Using the scale factor, we can find x as shown below:

x = 8.4 * scale factor

x = 8.4 * 5/3.5

x = 12

The lines with given coordinates are parallel i.e. C.

What are coordinates of a line segment?

The coordinates of a line segment are the coordinates of its two endpoints.

In two-dimensional Cartesian coordinates, each point is represented by an ordered pair of numbers (x,y), where x is the horizontal coordinate (also called the abscissa) and y is the vertical coordinate (also called the ordinate).

For example, if one endpoint of a line segment is at (3,5) and the other endpoint is at (-2,-1), then the coordinates of the line segment are (3,5) and (-2,-1).

Now,                                                                                                                 The two lines are  parallel not perpendicular and they don't intersect.  To determine if two lines are perpendicular, we can check if the slope of one line is the negative reciprocal of the slope of the other line. If the      slopes are equal, then the  lines are parallel.

For the first line, the slope is:

slope = (change in y) / (change in x) = (-3 - (-5)) / (-3 - (-5)) = 2/2 = 1

For the second line, the slope is:

slope = (change in y) / (change in x) = (2 - 1) / (4 - 3) = 1/1 = 1

Since the slopes are equal but not negative reciprocals, then lines are not perpendicular. And since the slopes are equal, the lines are parallel. Therefore, the answer is C.

The result is not equal to zero, (x - 10) is not a factor of x² + 3x - 40.

None of the given expressions (A, B, C, D) are factors of x² + 3x - 40.

To determine which expression is a factor of the given quadratic expression, we need to check if substituting the value from each expression into the quadratic expression results in zero. Let's evaluate each option:

A. (x - 4)

Substituting x - 4 into x² + 3x - 40:

(x - 4)² + 3(x - 4) - 40 = x² - 8x + 16 + 3x - 12 - 40 = x² - 5x - 36

Since the result is not equal to zero, (x - 4) is not a factor of x² + 3x - 40.

B. (x - 5)

Substituting x - 5 into x² + 3x - 40:

(x - 5)² + 3(x - 5) - 40 = x² - 10x + 25 + 3x - 15 - 40 = x² - 7x - 30

Since the result is not equal to zero, (x - 5) is not a factor of x² + 3x - 40.

C. (x - 8)

Substituting x - 8 into x² + 3x - 40:

(x - 8)² + 3(x - 8) - 40 = x² - 16x + 64 + 3x - 24 - 40 = x² - 13x

Since the result is not equal to zero, (x - 8) is not a factor of x² + 3x - 40.

D. (x - 10)

Substituting x - 10 into x² + 3x - 40:

(x - 10)² + 3(x - 10) - 40 = x² - 20x + 100 + 3x - 30 - 40 = x² - 17x + 30

Since the result is not equal to zero, (x - 10) is not a factor of x² + 3x - 40.

None of the given expressions (A, B, C, D) are factors of x² + 3x - 40.

It would take Jimbo 24 minutes to solve a 3-variable substitution problem alone.

Let's assume that Jimbo takes x minutes to solve a 3-variable substitution problem alone.

We know that Jimmy takes 8 minutes to solve the same problem alone, so his work rate is 1/8 of the problem solved per minute.

Together, Jimbo and Jim Bob can solve the same problem in 6 minutes. This means that their combined work rate is 1/6 of the problem solved per minute.

We can set up the following equation to represent the work rates:

1/8 + 1/x = 1/6

To solve for x, we can multiply both sides of the equation by 24x:

3x + 24 = 4x

x = 24

Therefore, it would take Jimbo 24 minutes to solve a 3-variable substitution problem alone.
