what is rhombus ?

A parallelogram has a unique variation known as a rhombus. A rhombus has opposing sides that are parallel and opposing angles that are equal. A rhombus also has equal-length sides and diagonals that are at right angles to one another. The term "rhombus" can also refer to a diamond or rhombus. A rhombus has equal opposite angles. At a 90° angle, the diagonals split in half. 180 degrees is the sum of adjacent angles.

given

There is a line that passes through the parallel line; the alternate interior angles are 3 and 39.

The alternative interior angles are similar, hence Angle 3 = 39.

Since the upper left triangle is a triangle, angles 3, 4, and the center angle all add up to 180 degrees. The angle in the middle is 90 degrees. hence, we may locate angle 4.

angle 4=51.

The staff at Larry's Lawns spends their workday mowing lawns, raking, and bagging leaves. They work an average of six hours per day. The mowing and raking typically takes four hours and an average of twenty-four bags of leaves are filled. Assuming the bags are filled at a constant rate, what is the average time it takes to fill one bag of leaves

Answers

Assuming the bags are filled at a constant rate, the average time it takes to fill one bag of leaves is 5 minutes.

To calculate the average time it takes to fill one bag of leaves, we need to know the total amount of time spent filling bags and divide that by the number of bags filled.

First, we know that the staff works an average of six hours per day. Since mowing and raking typically take four hours, we can assume that the remaining two hours are spent filling bags.

To find out how long it takes to fill one bag, we divide the total time spent filling bags by the number of bags filled. In this case, it would be:

(2 hours) / (24 bags) = 0.083 hours (or 5 minutes)

So the average time it takes to fill one bag of leaves is 5 minutes.

It's important to note that this is an average time and may not reflect the exact time it takes for each bag to be filled. Factors such as the size of the bag, the type of leaves being filled, and the skill level of the staff could all affect the time it takes to fill a bag.

A. 48.4
B. 135.9
C. 138.4
D. 228.4

Answers

In the above scenario, note that the total distance of the flight is given as: 48.4 miles (approximately). This is solved using the law of Sines to find x.

What is the law of Sines?

The connection between the sides and angles of non-right (oblique) triangles is defined by the Law of Sines. Simply put, it asserts that the ratio of the length of a triangle's side to the sine of the angle opposite that side is the same for all triangle sides and angles.

Thus, with regard to the problem modeled in the attached triangle, because two angles are given, the missing angle is 180° − (157° + 8°) or 15°. Use the Law of Sines to find x.

Using the law of ins we can state that:

Sin 8°/x = sin 15°/90

90 (Sin 8°) /x = Sin 15°

90 Sin 8° = x Sin 15°

90 Sin 8° / Sin 15° = x

90 (0.13917310096)/ 0.2588190451 = x

Thus,

x = 48.3951213156

On solving the provided question we can say that - the probability of the event will be there are two red sides, thus multiplying 16.6667 by two results in 33.3333%.

What is probability?

A branch of mathematics known as probability measures the possibility of an event happening or a proposition being true. The probability of an occurrence is a number between 0 and 1, where roughly 0 denotes the event's improbability and 1 denotes certainty. A probability is a numerical representation of the possibility or probability that a specific event will take place. Probabilities can alternatively be stated as percentages ranging from 0% to 100%, or as percentages from 0 to 1. the proportion between the number of events in a comprehensive collection of equally likely outcomes that lead to a certain occurrence and the entire number of outcomes.

Each side would be 50%, and if one side were divided among three people, it would equal 16.6667 per person.

2)

The slope of the function is 6.

3)

The linear function is (1/2)x - 4.

3x + 2y = 6 is a linear function.

What is a function?

function is a relationship between inputs where each input is related to exactly one output.

Example:

f(x) = 2x + 1

f(1) = 2 + 1 = 3

f(2) = 2 x 2 + 1 = 4 + 1 = 5

The outputs of the functions are 3 and 5

The inputs of the function are 1 and 2.

We have,

1)

f(x) = 4(2 + 3x) + 3

f(x) = (1/2)x² - 5

f(x)= 5 - x²

f(x) = 1 - 1/x

The graph of each function is given below.

The red line in the graph represents f(x) = 4(2 + 3x) + 3.

This is a straight line which means it is a linear function.

2)

f(x) = 2(3x - 7)

f(x) = 6x - 14

It is in the form of y = mx + c where m is the slope.

So,

m = 6

3)

f(x) = (1/2)x - 4

f(x) = x³ - 2

The graph is given below.

The red line represents f(x) = (1/2)x - 4.

This is a linear function.

4)

y = 3x + 12

y = x² + 2

y = 10x

y = 9

The graph is shown below.

The green curve is y = x² + 2.

This is not a linear function.

5)

y = 2x² - 6

This is not a linear function because we have x².

The graph is given below.

6)

Graph D represents a non-linear function.

7)

Graph B represents a non-linear function.

8)

If the rate of change between two (x, y) from the graph is the same then it is a linear function.

Table D has the same rate of change.

Rate of change = (y(2) - y(1)) / (x(2) - x(1))

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

Table D is a linear function.

9)

If the rate of change between two (x, y) from the graph is the same then it is a linear function.

Table B does not have the same rate of change.

Rate of change = (y(2) - y(1)) / (x(2) - x(1))

Table B is not a linear function.

In the triangle below, with right angle R, suppose that m is Angle Q=(5x-13) and m is Angle S=(4x-5) Find the degree measure of each angle in the triangle.

Answers

Answer:

Degree measure of each angle is 90⁰, 47⁰ and 43⁰

Step-by-step explanation:

since the triangle is right angled, we assume that Q and S are the other angles of this triangle R

Thus using the concept that angles inside a triangle add up to 180⁰ and we already have one angle as 90⁰( since the triangle is right angled). we therefore know that Q + S = 90⁰

5x - 13 + 4x - 5 = 90⁰

9x = 108

x = 12

We now replace x in Q and S to get the angles

Q = 5(12) -13

= 47⁰

S = 4(12) - 5

= 43⁰

Answers

Answer:

[tex]\huge\boxed{\text{4.2 feet}}[/tex]

Step-by-step explanation:

In order to solve this problem, we can use the basic trigonometric functions.

Let's first start to break down the triangle scenario we're given.

We know that the ladder is 10 ft tall. Given that it is slanted, it's likely the hypotenuse.We know the angle formed between the ladder and the ground is 65°. Since the ladder will form a 90° angle with the ground, the last angle will have to follow the triangle rule.The triangle rule is that all angles within a triangle will add up to 180°. Using this logic, we can find the measure of the third angle from the other two[tex]90+65+x=180[/tex], [tex]155+x=180[/tex], [tex]x=25[/tex]

Now we know the three angles of the triangle and one side.

We can find the other two sides (or just the base side, in our case), using trigonometric functions such as sin, cos, and tan. We can substitute in their formulas and find lengths based on angle measures.

We know using SOH CAH TOA the relationships between opposites, adjacents, and hypotenuses with these functions. SOH CAH TOA states that:

Sin = Opposite/HypotenuseCosine = Adjacent/HypotenuseTangent = Opposite/Adjacent

Using the triangle, we want to find a relationship that has the base we need as an opposite/adjacent that can use the hypotenuse (since it's the only side length we know.

Well, we can take the sin of the 25 degree angle - it's opposite is the base leg and the hypotenuse is 10.

We can then represent this using an equation:

[tex]\text{sin}(25) = \frac{\text{opposite}}{\text{hypotenuse}}[/tex] [tex]\text{sin}(25) = \frac{\text{opposite}}{10}[/tex]      (Since we know the hypotenuse is 10)[tex]\text{sin}(25) \cdot 10 = \text{opposite}[/tex] We know that sin(25) is roughly 0.4226 because of our. calculator. We can then multiply that by 10 to recieve 4.226. This rounds to 4.2 (to the nearest 10th).

Therefore, the length of the base leg is 4.2 feet

You work for a manufacturer of steel beams that will be used in construction of a heavily used bridge. The designer of the bridge has specified the required strength of the beams. Your job is to set-up a statistical analysis of the beam strength. Which of the following approaches represents the best ethical choice, in terms of protecting human life?a. Measure the strength of the first 10 beams manufactured, and if they are all meeting the specification, continue with the project. b. Measure the strengths from a random sample of the beams, and set-up a hypothesis test, with the null hypothesis that the beams meet the specifications. Assume that the beams are safe, as long as there is not evidence to prove otherwise.c. Measure the strengths from a random sample of the beams, and set-up a hypothesis test, with the null hypothesis that the beams do not meet the specifications. Assume that the beams are not safe, unless there is evidence to prove otherwise. A $73 ceramic vase costs $78.84 after sales tax is figured in.
