For the given two similar triangles the value of x is equal to 7 units.

Figure is attached.

In triangle ABC and DBE,

Measure of ∠ABC = Measure of ∠DBE

Measure of ∠ACB = Measure of ∠DEB

By AA,

ΔABC is similar to ΔACB with correspondence DBE ↔ ABC

In the triangle ABC,

Measure of side length AB = AD + DB

                                             = 6 + 8

                                             = 14

Measure of side length BC = 3x

In triangle DBE,

Measure of side length DB = 8

Measure of side length BE = 2x - 2

In similar triangle corresponding sides are in proportion

⇒ AB / DB = BC / BE

⇒14 / 8 = 3x / (2x -2 )

⇒14 ( 2x -2 ) = 3x (8 )

⇒ 28x - 28 = 24x

⇒ 28x - 24x = 28

⇒4x = 28

⇒ x = 7 units

Therefore, the value of x for the two similar triangles is 7 units.

Answer:

234

Step-by-step explanation:

the average rate of change of f(x) in the closed interval [ a, b ] is

\(\frac{f(b)-f(a)}{b-a}\)

here [ a, b ] = [3, 6 ] , then

f(b) = f(6) = \(3^{6}\) + 17 = 729 + 17 = 746

f(a) = f(3) = 3³ + 17 = 27 + 17 = 44 , then

average rate of change = \(\frac{746-44}{6-3}\) = \(\frac{702}{3}\) = 234

The distance between the given coordinates  (−5, −19) and (−5, 32) is given by 51 units.

Let us consider the coordinates of two given points be,

(x₁ , y₁ ) = ( -5 , -19 )

(x₂ , y₂ ) = (-5 , 32 )

Distance formula between two points is equals to,

Distance = √ ( y₂ - y₁)² + ( x₂ - x₁ )²

Substitute the values of the coordinates we have,

⇒ Distance = √ ( 32 - (-19))² + ( -5- (-5) )²

⇒ Distance = √ (32 +19)² + (-5 + 5)²

⇒ Distance = √ 51² + 0²

⇒ Distance =  51 units.

Therefore, the distance between the two points is equal to 51 units.

Step-by-step explanation:

To find the missing side lengths in the given right triangles, use trigonometric ratios.

\(\boxed{\begin{minipage}{9.4 cm}\underline{Trigonometric ratios} \\\\$\sf \sin(\theta)=\dfrac{O}{H}\quad\cos(\theta)=\dfrac{A}{H}\quad\tan(\theta)=\dfrac{O}{A}$\\\\where:\\ \phantom{ww}$\bullet$ $\theta$ is the angle. \\ \phantom{ww}$\bullet$ $\sf O$ is the side opposite the angle. \\\phantom{ww}$\bullet$ $\sf A$ is the side adjacent the angle. \\\phantom{ww}$\bullet$ $\sf H$ is the hypotenuse (the side opposite the right angle). \\\end{minipage}}\)

From inspection of the first triangle ABC, we have been given the angle, the side opposite the angle and the side adjacent the angle.

Therefore, to calculate the length of the adjacent side, x, substitute the values into the tangent ratio:

\(\implies \tan 18^{\circ}=\dfrac{15}{x}\)

\(\implies x\tan 18^{\circ}=15\)

\(\implies x=\dfrac{15}{\tan 18^{\circ}}\)

\(\implies x=46.165253...\)

\(\implies x=46.2\;\;\sf(nearest\;tenth)\)

Triangle LMN is a right triangle. Interior angles of a triangle sum to 180°.

Therefore, as m∠M = 50° and m∠MLN = 90°, then m∠MNL = 40°.

As KN is perpendicular to NM and m∠MNL = 40° then m∠KNL = 50°.

As KL is parallel to NM, then m∠K = 90°.  Therefore, m∠KLN = 40°.

(Refer to the attached diagram).

For right triangle LMN, we have been given the angle (∠M) and the side adjacent to the angle (LM). To find an expression for the length of the side opposite the angle (LN), use the tangent ratio:

\(\implies \tan 50^{\circ}=\dfrac{LN}{45}\)

\(\implies LN=45\tan 50^{\circ}\)

LN is the hypotenuse of right triangle KLN.

If we use ∠KNL as θ, then side KN is adjacent to the angle.

Therefore, to find the KN use the cosine ratio:

\(\implies \cos 50^{\circ}=\dfrac{KN}{LN}\)

\(\implies \cos 50^{\circ}=\dfrac{KN}{45\tan 50^{\circ}}\)

\(\implies KN=45\tan 50^{\circ}\cos 50^{\circ}\)

\(\implies KN=34.471999...\)

\(\implies KN=34.5\;\; \sf (nearest\;tenth)\)

As KL is the side opposite ∠KNL, to find KL use the sine ratio:

\(\implies \sin 50^{\circ}=\dfrac{KL}{LN}\)

\(\implies \sin50^{\circ}=\dfrac{KL}{45\tan 50^{\circ}}\)

\(\implies KL=45\tan 50^{\circ}\sin50^{\circ}\)

\(\implies KL=41.0821297...\)

\(\implies KL=41.1\;\;\sf (nearest\;tenth)\)

----------------------------------------------------------------------------------------

From inspection of the second triangle ABC, we have been given the angle, the side adjacent the angle and the hypotenuse.

Therefore, to calculate the length of the adjacent side, x, substitute the values into the cosine ratio:

\(\implies \cos 70^{\circ}=\dfrac{x}{46}\)

\(\implies x=46\cos 70^{\circ}\)

\(\implies x=15.732926...\)

\(\implies x=15.7\;\;\sf(nearest\;tenth)\)

Step-by-step explanation:

According to the study, economists are not more self-centered than persons in other classes because 51% of the envelopes returned from economics classes and 36% from other classes.

Simply put, probability measures how probable something is to occur. We can discuss the probabilities of various outcomes, or how likely they are, whenever we are unsure of how an event will turn out. Statistics is the study of events subject to probability.

At one classroom for economics and another for other topics, they dumped 122 stamped envelopes with addresses and $20 bills inside each.

Let the money returned = R

economics classes = E

other classes = O

a). The following gives the probability statement for the overall percentage of the money returned: 100.P (R)

b). The probability statement that the percentage of money recovered from economics classes is 100.P(R|E)

c). The probability statement that displays the percentage of money returned from the other classes is 100.P(R|O).

d). No, because P(R) is not equal to P(R|E), the money returned is not independent of the classes.

e).  According to the study, economists are not more self-centered than persons in other classes because 51% of the envelopes returned from economics classes and 36% from other classes.

The complete question is:

Three professors at George Washington University did an experiment to determine if economists are more selfish than other people. They dropped 122 stamped, addressed envelopes with $20 cash in two different classrooms (one economics, one not) on the George Washington campus. Of these, 42% were returned overall. From the economics class 51% of the envelopes were returned. From the other class 36% were returned.

From

the business, psychology, and history classes 31% were returned.

Let: R = money returned; E = economics classes; O = other classes

a. Write a probability statement for the overall percent of money returned.

b. Write a probability statement for the percent of money returned out of the economics classes.

c. Write a probability statement for the percent of money returned out of the other classes.

d. Is money being returned independent of the class? Justify your answer numerically and explain it.

e. Based upon this study, do you think that economists are more selfish than other people? Explain why or why not. Include numbers to justify your answer.

Answer:

0.1

-0.2

-0.5

Step-by-step explanation:

Each term is 0.3 less than the previous term

1.3 - 0.3 = 1

1 - 0.3 = 0.7

0.7 - 0.3 - 0.4

0.4 - 0.3 = 0.1

0.1 - 0.3 = -0.2

-0.2 - 0.3 = -0.5

The snail will take approximately 0.43 hours or 25.8 minutes to travel 12 feet at the speed of 8.5 meters per hour.

Given, A snail moves at a speed of 8.5 meters per hour, 1m = 3.28ft. Let's convert meters per hour into feet per hour by multiplying it with 3.28ft/m. So, 8.5 meters per hour = 8.5 × 3.28 feet per hour ≈ 27.88 feet per hour.

Now, to calculate the time taken by a snail to travel 12 feet, we can use the formula: Time = Distance ÷ Speed

Time taken = 12 feet ÷ 27.88 feet per hour ≈ 0.43 hours (rounded to two decimal places)

Now, let's convert 0.43 hours to minutes by multiplying it with 60 minutes per hour: 0.43 hours × 60 minutes per hour ≈ 25.8 minutes (rounded to one decimal place). Therefore, it will take approximately 0.43 hours or 25.8 minutes for the snail to travel 12 feet at the speed of 8.5 meters per hour.

Answer:

  60+16√30 cm² ≈ 147.64 cm²

Step-by-step explanation:

You can figure the height of the object from ...

  V = Bh

  120 cm^3 = (30 cm^2)h

  4 cm = h . . . . . divide by 30 cm^2

However, this is insufficient to tell you the surface area.

__

If you assume that the base is square, then its side length is

  A = s^2

  s = √A = √(30 cm^2) = (√30) cm

The lateral surface area can then be found from the perimeter of the base and the height

  LA = Ph = (4√30 cm)(4 cm) = 16√30 cm^2

The total surface area will be the sum of this lateral area and the area of the two bases:

 total area = 16√30 cm^2 +2·30 cm^2

 total area = (60 +16√30) cm^2 ≈ 147.64 cm^2

__

For any other shape, the total area will be larger. It can be arbitrarily large, unless limits are put on the dimensions of the object.

A yield sign measures 24 inches on each of its three sides ( equilateral )then the area of the sign is 249.4

Given,

24 inches on each of its three side. (See in attached picture)

Consider ADB,

As it is an equilateral triangle, BD = BC/2 = 12 inches

By Pythagoras theorem,

AB^2 = BD^2 + AD^2

24^2 = 12^2 + AD^2

24^2 – 12^2 = AD^2

576-144 = AD^2

432= AD^2

20.78= AD

Area = ½ (base * height)

Since the sequence is always decreasing and cannot go below the lower bound, it becomes increasingly closer to the lower bound, and thus converges to a limit.

A sequence is said to be decreasing if each term is smaller than the previous one, and bounded below if there exists a lower bound such that no term in the sequence is smaller than this bound. In this case, the sequence is decreasing and bounded below by 0.

When a sequence is both decreasing and bounded below, it must have a limit because the terms cannot continue to decrease indefinitely, as they cannot go below the lower bound (in this case, 0). This means that as we progress through the terms of the sequence, the difference between consecutive terms will decrease and eventually approach a constant value.

The limit of a sequence is a value that the terms of the sequence approach as they get closer and closer to the end. In this situation, the limit is the smallest possible value that the sequence can approach, without going below the lower bound.

The value of m, the slope of the line of best fit, is 0.2.

How to find the value of "m" in the equation y = mx + b?

To find the line of best fit and determine the value of m in the equation

\(y = mx + b,\)we can use linear regression analysis with the given data points \((1, 4), (2, 3), (3, 5), (4, 4)\), and \((5, 5)\).

Using technology such as a spreadsheet or graphing calculator, we can input the data points and perform linear regression to find the equation of the line that best fits the data. This analysis will provide us with the values of m and b.

When performing linear regression on the given data, we find that the equation of the line of best fit is\(y = 0.2x + 3.4.\)

Therefore, the value of m is 0.2. This indicates that for every one-unit increase in the x-coordinate, the corresponding y-coordinate will increase by 0.2 units.

Please note that the line of best fit is determined using statistical calculations, and the result may vary slightly depending on the software or tool used for the analysis.

Answer:

can you give me the answer to this question sin y minus cos (y + 20), sin theta minus cos theta equals to 0 cos theta equals to sin theta - 10​

Step-by-step explanation:

To solve sin y - cos (y + 20) = 0, we can rearrange it as sin y = cos (y + 20).

Then, we can use the identity sin (90 - x) = cos x to rewrite the right side as cos (y + 20) = sin (70 - y).

Substituting this into the equation, we get sin y = sin (70 - y).

Now, there are two possibilities:

y = 70 - y, which gives y = 35 degrees.

y = 180 - (70 - y), which gives y = 105 degrees.

To solve cos theta = sin theta - 10, we can rearrange it as cos theta - sin theta = -10 and then use the identity cos (x - 90) = sin x to rewrite it as -sin (theta - 90) = -10.

Taking the inverse sine of both
