One triangle can be made with the given information.

Herewe have the triangle LMN, and we know that:

∠L = 31°

LM = 6.9 cm

MN = 3.4cm

So, we know one angle, one of the sides adjacent to the angle, and the side opposite to the angle.

Below you can see a diagram of the triangle, you can see that the missing length is defined by the information that we know (we could use the cosine law and a system of equations to find it). Then, basically, we can see that the lengths of the 3 sides are fixed.

Only one triangle can be made with 3 fixed sides, so that is the answer.

Answer:

The other small angle is 53.5 degrees

Step-by-step explanation:

We know that a right triangle has to have a 90 degree angle and 2 other small angles.

All triangles when adding up all of their "degrees" has tp equal 180 degrees.

Since we know that there is a 90 degree angle and a 36.5 degree angle.

All we have to do is add 90 plus 36.5, then subtract that sum onto 180.

90 + 36.5 = 126.5

180 - 126.5 = 53.5

So the answer is 53.5 degrees.

Hope this helps! :)

૮ ・ﻌ・ა

A right triangle is a triangle in which the angles sum up to 180 degrees. It is made up of three sides : the height, the base and the hypotenuse. One of the angles in a right triangle has a value of 90 degrees.

Missing angle  = sum of angles in a triangle - (sum of the two given angles)

Missing angle = 180 - ( 90 + 36.5)

180 - 126.50

= 53.5 degrees

Left Column: AC bisects ZBCA ZDCA. Right Column: Angle ZBAC = Angle ZDCA (Angle Bisector Theorem).

Angle bisector theorem states that in any triangle, the line that bisects an angle also divides the opposite side into two segments that are proportional to the other two sides of the triangle. This theorem can be used to prove that the angle bisector of any triangle is the perpendicular bisector of the opposite side. In other words, the line that bisects the angle of a triangle will also divide the opposite side into two segments with lengths that are equal to the ratio of the other two sides of the triangle.

The area of triangle (A) is 210 cm².

What is the area of the triangle and perimeter of the triangle?

If a, b, and c are the sides of the triangle, then

Perimeter of the triangle = (a + b + c) units.

Area of the triangle = \(\sqrt{(s(s - a) (s - b) (s - c)) }\)

The semi-perimeter of the triangle, s = (a + b + c)/2

Let the triangle is ABC,

and AB = 3x - 1, BC = 4x + 1 and AC = 3x.

       Perimeter = 70

       AB + BC + AC = 70

      3x-1 + 4x + 1 +3x = 70

       10x = 70

          x = 7

AB = a = 3x - 1 = 20

BC = b = 4x + 1 = 29

AC = c = 3x = 21

Now semi-perimeter = s = 70/2

                                     s = 35

      Area of the triangle = \(\sqrt{(s(s - a) (s - b) (s - c)) }\) 

                                    \(=\sqrt{35(35-20)(35-29)(35-21)}\\\\\\=\sqrt{35(15)(6)(14)}\\\\=\sqrt{44100}\\\\=210\)

yes, the given answer is correct.

a) A department manager receiving an allocation of costs will care about management's methodology of overhead allocation because the overhead costs allocated to their department will have a direct impact on the department's profitability and cost efficiency.

b) The allocation base is the measure used to determine how much of the overhead costs should be allocated to a particular department or product, while the allocation rate is the amount of overhead costs allocated to each unit of the allocation base

c) Budgets are an important tool for cost planning, but their effectiveness depends on how well they are developed and implemented.

a) If the allocation method used by management is not accurate or fair, it could result in the department being burdened with more costs than they actually incur, which could affect their ability to meet their targets and objectives. It is, therefore, important for department managers to ensure that the allocation of costs is done fairly and accurately.

b) The allocation base and rate are important because they determine how the overhead costs are allocated to different departments or products.

Different allocation bases and rates can result in significantly different amounts of overhead costs being allocated to different departments or products, which can impact their profitability. While all of the overhead costs eventually make their way to the income statement, the allocation of these costs can have a significant impact on the accuracy of the income statement and the ability of the organization to make informed decisions.

c) Budgets can be helpful in providing a roadmap for achieving the organization's goals and objectives, but they need to be flexible enough to adapt to changing circumstances and priorities.

The budget(s) that are most important to the organization's success will depend on the nature of the organization and its objectives. However, typically the operating budget, capital budget, and cash budget are the most important budgets for most organizations.

The government's budget process is similar to the operating budgeting process described in the chapter in that it involves the development of a budget to allocate resources and achieve goals. However, the government's budget process is more complex and involves additional considerations such as political priorities and public opinion. Additionally, the government's budget process involves a more detailed review and approval process than the operating budgeting process.

This is true, so we have shown that the solution x = 4 is indeed of the form x. To solve an equation that has only one solution, we need to first identify the equation. Let's say the equation is given as:

x + 3 = 7

To solve for x, we need to isolate it on one side of the equation. We can do this by subtracting 3 from both sides:

x + 3 - 3 = 7 - 3

This simplifies to:

x = 4

So the solution to this equation is x = 4.

Now, to show that the solution is of the form x, we can substitute the value of x into the original equation and see if it satisfies the equation.

In this case, we have:

4 + 3 = 7

This is true, so we have shown that the solution x = 4 is indeed of the form x.

Overall, the steps to solve an equation with one solution are:

1. Identify the equation
2. Isolate x on one side of the equation
3. Simplify the equation to find the value of x
4. Substitute the value of x into the original equation to check that it satisfies the equation
5. If the substituted value satisfies the equation, the solution is of the form x.

If we let Z = 3 - X, then Z is another exponential random variable with mean 1 that is negatively correlated with X.

Let Y = 2 - X, where X is an exponential random variable with mean 1.

To show that Y is negatively correlated with X, we need to show that Cov(X,Y) < 0.

Cov(X,Y) = E[XY] - E[X]E[Y]

Since X and Y are both exponentially distributed with mean 1, we have:

E[X] = 1, E[Y] = 2 - E[X] = 1

E[XY] = E[X(2-X)] = 2E[X] - E[X^2] = 2 - Var(X)

Var(X) = E[X^2] - (E[X])^2 = 1 - 1^2 = 0

Therefore, Var(X) = 0, which means that E[XY] = 2, and Cov(X,Y) = E[XY] - E[X]E[Y] = 2 - 1*1 = 1 > 0.

Since Cov(X,Y) > 0, we know that Y is positively correlated with X. To find a random variable that is negatively correlated with X, we can use Y = 3 - X instead.

Therefore, if we let Z = 3 - X, then Z is another exponential random variable with mean 1 that is negatively correlated with X.

The altitude of the airplane after 4 minutes of descent, descending at a rate of 172 feet every 30 seconds is 11,109 feet.

The descent rate of the airplane is given as 172 feet every 30 seconds. To calculate the altitude after 4 minutes (240 seconds) of descent, we need to determine the number of descent intervals and subtract the cumulative descent from the initial altitude.

The number of descent intervals in 4 minutes can be calculated as follows:

4 minutes * (60 seconds/1 minute) / (30 seconds/interval) = 8 intervals

Next, we calculate the cumulative descent:

8 intervals * 172 feet/interval = 1,376 feet

Finally, we subtract the cumulative descent from the initial altitude:

12,645 feet - 1,376 feet = 11,109 feet

The airplane, initially at an altitude of 12,645 feet, descends at a rate of 172 feet every 30 seconds for a total of 4 minutes. This totals a descent of 1376 feet, leaving the airplane at an altitude of 11,269 feet after the 4 minute descent.

The subject of this problem is Mathematics and it involves calculating the new altitude of a descending airplane. The scenario involved is that an airplane, flying at an altitude of 12,645 feet, starts to descend at a rate of 172 feet every 30 seconds. The pilot continues this descent for 4 minutes.

The first step in solving this is to know how many 30-second intervals are in 4 minutes. Since there are 2 intervals per minute, this means there are 8 intervals in 4 minutes. If the plane descends 172 feet per interval, over 8 intervals, it descends a total of 172 feet x 8 = 1376 feet.

The final altitude of the plane would be the original altitude minus the total decline. In this case, it would be 12,645 feet - 1376 feet, which equals 11,269 feet. Therefore, the airplane will be at an altitude of 11,269 feet after 4 minutes of descent.

The probability that both Event A (the first die is 4 or less) and Event B (the second die is even) will occur is 1/3.

To find the probability that both Event A and Event B will occur, we need to calculate the individual probabilities of each event and then multiply them together.

Event A: The first die is 4 or less.

There are 6 possible outcomes for the first die (numbers 1 to 6), and out of those, 4 outcomes (numbers 1, 2, 3, and 4) satisfy the condition. Therefore, the probability of Event A is 4/6, which simplifies to 2/3.

Event B: The second die is even.

For a fair six-sided die, there are 3 even numbers (2, 4, and 6) out of a total of 6 possible outcomes. Therefore, the probability of Event B is 3/6, which simplifies to 1/2.

To find the probability that both events will occur, we multiply the probabilities of Event A and Event B:

Probability of both events occurring = Probability of Event A * Probability of Event B

The probability that a person treated for an energy drink-related emergency was under 40 given that the person was at least 18 years old is approximately 0.550 or 55.0%.

In general, probability is defined as the ratio of the number of favourable outcomes to the total number of outcomes in a sample space. Event probability P(E) = (number of favourable outcomes) (Sample space).

We must use conditional probability to determine the likelihood that a person treated for an energy drink-related emergency was under 40, given that the person was at least 18 years old.

We can use the following formula:

P(A | B) = P(A and B) / P(A and B) (B)

where A is the event "the person is under 40" and B is the event "the person is over 18".

According to the table, 11,146 people under the age of 40 and over the age of 18 were treated for energy drink-related emergencies. The total number of people over the age of 18 who have been treated for energy drink-related emergencies is 20,244.

So,

P(A, B) = 11,146

P(B) = 20,244

Therefore,

P(A and B) / P(B) = 11,146 / 20,244 0.550

So the probability that a person treated for an energy drink-related emergency was under 40 is approximately 0.550 or 55.0% if the person was at least 18 years old.
