Answer:

the measure of the angle is 43.4 degrees, and the measure of its supplementary angle is 180 - 43.4 = 136.6 degrees.

Step-by-step explanation:

Let x be the measure of the angle in degrees.

By definition, supplementary angles add up to 180 degrees, so the measure of the supplementary angle is 180 - x degrees.

According to the problem, the angle measures 136.6 degrees less than the supplementary angle, so we can write:

x = (180 - x) - 136.6

Simplifying the right-hand side, we get:

x = 43.4

Therefore, the measure of the angle is 43.4 degrees, and the measure of its supplementary angle is 180 - 43.4 = 136.6 degrees.

Using the LCM formula, it is deduced that James took the longest to finish the race.

What is LCM?

In mathematics, the least common multiple is sometimes referred to as LCM or the lowest common multiple. The smallest number among all the common multiples of the provided numbers is the least common multiple of two or more numbers.

Let's assume that James took time "J" to finish the race. Then -

Duante took 8/9 of James' time, which is (8/9)J

Kofi took 7/8 of James' time, which is (7/8)J

To determine who took the longest to finish the race, we need to compare their times.

Let's start by comparing Duante and James -

Duante's time = (8/9)J

James' time = J

Since Duante took less time than James, we can conclude that James did not take the longest to finish the race.

Now let's compare Kofi and James -

Kofi's time = (7/8)J

James' time = J

To compare these times, we need to express them with a common denominator.

The least common multiple of 8 and 1 is 8, so we can rewrite James' time as (8/8)J:

Kofi's time = (7/8)J

James' time = (8/8)J

Now we can compare the times -

Kofi's time = (7/8)J < (8/8)J = James' time

Therefore, Kofi took the least time to finish the race, and James took the longest.

What is matrix ?

A matrix is a rectangular array of numbers, symbols, or expressions arranged in rows and columns.

Here is an example of a 2x3 matrix that represents a problem in industrial engineering:

Suppose a company produces two types of products, Product A and Product B, and they use three different machines to manufacture these products. The number of hours required to produce each unit of each product using each machine is given by the following matrix:

| 2  3  4 |

| 4  2  3 |

This matrix represents a system of linear equations that can be solved using matrix inversion to find the number of hours required to produce a given number of units of each product. For example, suppose the company needs to produce 100 units of Product A and 50 units of Product B. To find the number of hours required for each machine, we can set up the following system of equations:

2x + 3y + 4z = 100

4x + 2y + 3z = 50

where x, y, and z represent the number of hours required for each machine.

To solve this system of equations using matrix inversion, we can first write the system in matrix form:

| 2  3  4 |   | x |   | 100 |

| 4  2  3 | * | y | = | 50  |

| 0  0  0 |   | z |   | 0   |

Next, we need to find the inverse of the coefficient matrix:

| 2  3  4 |^-1 = 1/10 | -6  12 -3 |

| 4  2  3 |          |  9 -6  4 |

| 0  0  0 |          |  0  0  0 |

Finally, we can solve for x, y, and z by multiplying both sides of the equation by the inverse of the coefficient matrix:

| x |   | -6  12 -3 |   | 100 |   | 90 |

| y | = |  9 -6  4  | * | 50  | = | 20 |

| z |   |  0  0  0  |   | 0   |   | 0  |

Therefore, it would take 90 hours on the first machine, 20 hours on the second machine, and 0 hours on the third machine to produce 100 units of Product A and 50 units of Product B.

The object represented by a 3..75 kg stone is scalar object

The quantity "3.75 kg" is a scalar because it is a single value that only has magnitude, and it does not have a direction associated with it.

On the other hand, the force of gravity acting on the stone and the tension force of the rope holding the stone up are vector quantities because they have both magnitude and direction.

It is important to note that the stone itself does not have a direction associated with it, but the forces acting on it do have direction.

Therefore, when describing the motion of the stone, both scalar and vector quantities are involved.

The price of a general admission floor ticket is $25.

What is the system of equations?

A system of equations is a collection of one or more equations that are considered together. The system can consist of linear or nonlinear equations and may have one or more variables. The solution to a system of equations is the set of values that satisfy all of the equations in the system simultaneously.

Let's start by defining some variables:

Let b be the price of a balcony ticket

Let f be the price of a general admission floor ticket

We can set up a system of two equations based on the information given in the problem:

77b + 69f = 5,883 (equation 1 for Friday's show)

75b + 69f = 5,775 (equation 2 for Saturday's show)

We can use either substitution or elimination to solve for b and f. Let's use elimination by subtracting equation 2 from equation 1:

(77b + 69f) - (75b + 69f) = 5,883 - 5,775

2b = 108

b = 54

Now that we know the price of a balcony ticket is $54, we can substitute this value into either equation to solve for f. Let's use equation 1:

77(54) + 69f = 5,883

4,158 + 69f = 5,883

69f = 1,725

f = 25

Therefore, the price of a general admission floor ticket is $25.

Without any measurements, it is not possible to give a numerical estimate for the real height of the lamp post in metres. However, we can use the scale of the drawing to make an estimate.

Let's assume that the scale of the drawing is 1 centimetre (cm) represents 0.5 metres (m) in real life. This means that every 1 cm in the drawing represents 0.5 m in real life.

If we measure the height of the lamp post in the drawing and find that it is approximately 15 cm, we can estimate the real height of the lamp post as follows:

Real height of lamp post = (15 cm) x (0.5 m/1 cm) = 7.5 m

Therefore, using our estimated scale of the drawing, we can estimate that the real height of the lamp post is around 7.5 metres. However, this estimate is only as accurate as the assumptions we made about the scale of the drawing.

The equation of the line perpendicular to 4x + 36y = 288 and passing through the point (10, 8) is: y = 9x - 98

To find the equation of the line perpendicular to 4x + 36y = 288, we need to first find the slope of the given line.

We can rewrite the equation in slope-intercept form y = mx + b by solving for y:

4x + 36y = 288

36y = -4x + 288

y = (-1/9)x + 8

Therefore, the slope of the given line is -1/9

The slope of a line perpendicular to this line is the negative reciprocal of the slope of the given line.

So, the slope of the line we want to find is:

m = -1 / (-1/9) = 9

The equation is then calculated as

y - y1 = m(x - x1)

where m is the slope and (x1, y1) is the given point.

Plugging in the values, we get:

y - 8 = 9(x - 10)

Simplifying, we get:

y = 9x - 98

Therefore, the equation of the line perpendicular is: y = 9x - 98

v = (y – c)/q

b[tex]_{yx}[/tex] = q/p × bvu

Given: u = (x-100)/2 and v = (y-200)/3

Thus, q = 3 and p = 2

Since the regression coefficient of Y on X = 1.2.

Thus, b[tex]_{yx}[/tex] = 1.2

b[tex]_{yx}[/tex] = q/p × bvu

We would need to survey at least 600 randomly selected air passengers to be 90% confident that the sample percentage is within 1.5 percentage points of the true population percentage.

As a number out of 100, a percentage is a technique to express a fraction or a proportion. The sign "%" stands in for the word "percent," which is a contraction of "per hundred."

To determine the sample size for the survey, we can use the following formula:

n = [tex](Z^2 * p * q) / E^2[/tex]

Where:

n is the required sample size

Z is the Z-value for the desired confidence level (in this case, Z = 1.645 for a 90% confidence level)

p is the estimated population proportion (we don't know this yet, so we will assume a conservative estimate of 0.5)

q is the complementary probability of p (q = 1 - p)

E is the maximum error or margin of error (in this case, E = 0.015)

Plugging in the values, we get:

n = ([tex]1.645^2[/tex] * 0.5 * 0.5) / [tex]0.015^2[/tex]

n = 599.27

Rounding up to the nearest whole number, we get a required sample size of 600.

Therefore, we would need to survey at least 600 randomly selected air passengers to be 90% confident that the sample percentage is within 1.5 percentage points of the true population percentage.

How to solve and what is percentage?

To find the percentage you put down on the home, you need to divide the amount you put down (the down payment) by the total cost of the home, and then multiply by 100 to convert to a percentage.

The down payment was $8,000 and the total cost of the home was $64,000.

So the percentage you put down is:

($8,000 / $64,000) x 100% = 12.5%

Therefore, you put down 12.5% of the total cost of the home.
