Question:-

The area of two similar triangles are 81 cm2 and 49 cm² respectively. If one of the sides of the first triangle is 6.3 cm, find the corresponding side of the other triangle.​

Answers

Let's assume that the corresponding side of the second triangle is \(\displaystyle\sf x\).

The ratio of the areas of two similar triangles is equal to the square of the ratio of their corresponding sides. Therefore, we can set up the following proportion:

\(\displaystyle\sf \left( \dfrac{x}{6.3} \right)^{2} =\dfrac{49}{81}\)

To find \(\displaystyle\sf x\), we can solve the proportion above:

\(\displaystyle\sf \left( \dfrac{x}{6.3} \right)^{2} =\dfrac{49}{81}\)

Taking the square root of both sides:

\(\displaystyle\sf \dfrac{x}{6.3} =\sqrt{\dfrac{49}{81}}\)

Simplifying the square root:

\(\displaystyle\sf \dfrac{x}{6.3} =\dfrac{7}{9}\)

Cross-multiplying:

\(\displaystyle\sf 9x = 6.3 \times 7\)

Dividing both sides by 9:

\(\displaystyle\sf x = \dfrac{6.3 \times 7}{9}\)

Calculating the value:

\(\displaystyle\sf x = 4.9\)

Therefore, the corresponding side of the second triangle is \(\displaystyle\sf 4.9 \, cm\).

Step-by-step explanation:

You want the simplified form of (5b^1c^-5)^-3(4b^0a^2)^-5.

Rules of exponents

There are several useful rules of exponents here:

  (ab)^c = (a^c)(b^c)

  (a^b)^c = a^(bc)

  a^-b = 1/(a^b)

Application

Simplifying the top-level exponents first, we have ...

  \((5b^1c^{-5})^{-3}(4b^0a^2)^{-5}=(5^{-3}b^{1(-3)}c^{(-5)(-3)})(4^{-5}b^{0(-5)}a^{2(-5)})\\\\=(5^{-3}4^{-5})a^{-10}b^{-3+0}c^{15}=\dfrac{1}{5^34^5}a^{-10}b^{-3}c^{15}=\boxed{\dfrac{1}{128000}a^{-10}b^{-3}c^{15}}\)

In terms of answer requirements:

  n = 1/128000

  r = -10

  s = -3

Show that the angle bisector of an equilateral triangle is perpendicular to the base​

Answers

To show that the angle bisector of an equilateral triangle is perpendicular to the base​, we can assume an equilateral triangle with sides ABC. Next, we can get an angle bisector in the middle represented by BD which becomes perpendicular to the base BC.  

How to prove that the angle bisector is perpendicular to base

After getting the angle bisector, we would see that the line segment BD, divides angle BAC into two equal angles, each measuring 30 degrees. Now, we can draw a perpendicular line from point D to the base BC.

We could also draw a line E, which is the perpendicular line that intersects the base BC. We want to show that BD is perpendicular to BC, which means we need to show that angle BDE is a right angle.

Since the sum of angles BDA and ADE is 90 degrees (they form a right angle), and the sum of angles BAD, ABD, and BDA is 180 degrees, it follows that angle BDE must be a right angle.

Therefore, we have shown that the angle bisector of an equilateral triangle is perpendicular to the base.

The sum of the speeds of two trains is 721.4 miles per hour. If the speed of the first train is 4.6 mph faster than the second train, find the speeds of each

Answers

Given:

The sum of the speeds of two trains is 721.4

Let the speed of the trains are x and y

So,

\(x+y=721.4\rightarrow(1)\)

And the speed of the first train is 4.6 mph faster than the second train

So,

\(x-y=4.6\rightarrow(2)\)

Solve the equations (1) and (2) to find x and y

Add the equations to eliminate (y) then solve for (x):

\(\begin{gathered} 2x=721.4+4.6 \\ 2x=726 \\ x=\frac{726}{2}=363 \end{gathered}\)

Substitute (x) into the first equation then solve for (y):

\(\begin{gathered} 363+y=721.4 \\ y=721.4-363=358.4 \end{gathered}\)

So, the answer will be:

The speeds of the trains are 363 mph and 358.4 mph

Find the probability that a randomly selected point within the square falls in the red-shaded triangle. 3 3 4 P = [?] 4

Answers

The required probability is 3 √7 / 32.

Given, a square with sides of length 4 units and a red-shaded triangle with sides 3 units, 3 units and 4 units. We need to find the probability that a randomly selected point within the square falls in the red-shaded triangle.To find the probability, we need to divide the area of the red-shaded triangle by the area of the square. So, Area of square = 4 × 4 = 16 square units. Area of triangle = 1/2 × base × height.

Using Pythagorean theorem, the height of the triangle is found as: h = √(4² − 3²) = √7

The area of the triangle is: A = 1/2 × base × height= 1/2 × 3 × √7= 3/2 √7 square units. So, the probability that a randomly selected point within the square falls in the red-shaded triangle is:  P = Area of triangle/Area of square= (3/2 √7) / 16= 3 √7 / 32.

Find the value of x in each case:

Find the value of x in each case:

Answers

Answer:

\( x = 18 \)

Step-by-step explanation:

Given:

Angle ABC = 2x

Angle CDE = 8x

Required:

Value of x

SOLUTION:

Line AB is parallel to line CD, therefore, angle ABC and angle BCD are alternate interior angles. Alternate interior angles are equal. Thus:

Angle ABC = Angle BCD = 2x

Since, line BC is parallel to line DE, angle BCD and angle CDE are consecutive interior angles.

Consecutive interior angles are supplementary, therefore:

Angle BCD + Angle CDE = 180°

\( 2x + 8x = 180 \)

Use this equation to solve for x

\( 10x = 180 \)

Divide both sides by 10

\( \frac{10x}{10} = \frac{180}{10} \)

\( x = 18 \)

DEF and RST are complementary angles. This means they sum up to 90°

Thus,

(3(-5 + 2x)) + (x - 7) = 90

(3(-5 + 2x)) + (x - 7) = 90

(-15 + 6x) + (x - 7 ) = 90

AB and AD are tangent to circle C. Find the length of AB, if AB = 8x and AD = x + 9. Round your answer to 2 decimal places.​

Answers

To find the length of AB, we need to use the properties of a tangent to a circle.

When a line is tangent to a circle, it forms a right angle with the radius drawn to the point of tangency. This means that triangle ABD is a right triangle with AB as the hypotenuse.

We can use the Pythagorean theorem to find the length of AB:

AB^2 = AD^2 + BD^2

Since AD = x + 9 and BD = 8x - (x + 9) = 8x - x - 9 = 7x - 9, we can substitute these values into the equation:

(8x)^2 = (x + 9)^2 + (7x - 9)^2

64x^2 = x^2 + 18x + 81 + 49x^2 - 126x + 81

64x^2 = 50x^2 - 108x + 162

14x^2 + 108x - 162 = 0

Dividing the equation by 2, we get:

7x^2 + 54x - 81 = 0

Using the quadratic formula:

x = (-b ± √(b^2 - 4ac)) / (2a)

a = 7, b = 54, c = -81

x = (-54 ± √(54^2 - 4 * 7 * -81)) / (2 * 7)

x = (-54 ± √(2916 + 2268)) / 14

x = (-54 ± √5184) / 14

x = (-54 ± 72) / 14

Now we solve for x:

Case 1: x = (-54 + 72) / 14 = 18 / 14 = 9 / 7

Case 2: x = (-54 - 72) / 14 = -126 / 14 = -9

Since the length of a segment cannot be negative, we discard the second case and focus on the positive solution.

Therefore, x = 9/7.

Substituting this value back into AB = 8x:

AB = 8 * (9/7) = 72/7 ≈ 10.29

Rounding to 2 decimal places, the length of AB is approximately 10.29 units.

Answer:

To find the length of AB, we can use the property that two tangents to a circle from the same external point are equal. This means that AB = AD. Substituting the given values, we get:

8x = x + 9

Solving for x, we get:

x = 1.5

Therefore, AB = 8x = 8(1.5) = 12.

To check our answer, we can use the Pythagorean theorem on triangle ABD, since AB is perpendicular to BD at the point of tangency. We have:

AB^2 + BD^2 = AD^2

Substituting the values, we get:

12^2 + BD^2 = (1.5 + 9)^2

Simplifying, we get:

BD^2 = 56.25

Taking the square root of both sides, we get:

BD = 7.5

Hence, the length of AB is 12 and the length of BD is 7.5.

An office building worth $1 million when completed in 2010 is being depreciated linearly over 50 years. What was the book value of the building in 2014? What will it be in 2022? (Assume the scrap value is $0.)

Answers

Answer:

To calculate the book value of the building, we need to calculate the annual depreciation amount and multiply it by the number of years elapsed since the building was completed.

The annual depreciation amount is calculated as: $1 million / 50 years = $20,000

In 2014, the book value of the building was: $1 million - ($20,000 * (2014 - 2010)) = $1 million - ($20,000 * 4) = $960,000

In 2022, the book value of the building will be: $1 million - ($20,000 * (2022 - 2010)) = $1 million - ($20,000 * 12) = $680,000

Mr. Montes derives his answers from a random answer generator; same way Amisha generated her answers by random selection.

QUESTION 1

If you want to find the odds that Amisha got at least 3/5 of the answers correctly, would you use a permutation or a combination?

ANSWER TO QUESTION 1

You would use a combination. Note that as much as 'permutation' is distinctly defined from 'combination', in many complex cases both are used to derive the solution. In this case though, a combination is used. For each of the 5 questions, there are a number of possible answers. Questions 1 and 2 have only two possible answers (also known as options) while questions 3, 4 and 5 have four possible answers/options to choose from. Amisha can only have one set of five answers; each to each question. So this is a combination! If you want to find the odds that Amisha got at least 3 of her 5 answers correct, you would use a combination of the various possible answers to check.

QUESTION 2

Find "Set 1 ∩ Set 2" and explain the notation in the sentence.

ANSWER TO QUESTION 2

First list out relevant information:

- The correct answers to questions 3, 4 and 5 are respectively C, B, A

- The universal set consists of five students: S1, S2, S3, S4, S5 hence

Ц = {S1, S2, S3, S4, S5}

Next, enlist the elements of each defined set

Set 1: {S1, S2, S3, S4, S5}     Set 2: {S2, S3, S4}     Set 3: {S4, S5}

Note: Set 1 is equal to the universal set.

Now this notation "∩" means "intersect". It requires an action - checking out which elements in one set also appear in a second set and then bringing those elements to form a new set.

In the case of this question, we're to find Set 1 intersect Set 2. The elements present in Set 1 and also present in Set 2 are {S2, S3, S4}.

If you look closely, you'll observe that these are the same elements in Set 2! This brings to remembrance, one of the laws of sets:

The intersect of any subset and the universal set (recall that Set 1 happens to be equal to or have the same elements as the universal set) is equal to that subset.

So the answer to question 2 is

Set 1 ∩ Set 2 = Set 2

QUESTION 3

Find "Set 2 ∪ Set 3" and explain the notation in the sentence.

ANSWER TO QUESTION 3

The notation ∪ represents "union". This is the act of putting together the elements in two sets, to form a new set. In this activity, if an element appears in both sets, it is only written once in the new set, not twice.

So, Set 2 union Set 3 = {S2, S3, S4, S5}

As earlier stated, Student 4 isn't appearing twice in the new set.

QUESTION 4

Find the ' of Set 1 and explain the notation in this sentence.

ANSWER TO QUESTION 4

The symbol ' means "complement of a set". Finding the complement of a set is like subtracting the elements of that set from the universal set.

Since Set 1 contains the same elements as the universal set, subtracting Set 1 from the universal set will give you nothing. In this case, the complement of Set 1 is a null set!

Set 1 ' Ц = { }  or  ∅

where the empty bracket symbol and the slashed zero symbol represent null set.

Kudos!

However, at the end of the 15th century, European explorers began sailing to the far ends of the Earth, seeking out places they thought no one had ever been. The Dangers of Exploration Sailing out into uncharted waters was an incredibly dangerous thing to do. No Europeans really knew what was out there. Uneducated people still thought the world was flat and that sailing too far could mean falling off the end of the world. The explorers and sailors knew better, but they still were only guessing at where they were going. Sailing into unknown territory could lead to attack by enemy ships or pirates. The explorers also didnt know how long their trips would take, so they were risking starvation and dying of thirst (drinking the ocean water would kill them). They also risked death by diseases such as scurvy, caused by lack of Vitamin C (known for its symptoms of bloody gums). All ocean ships were still made out of wood, and the high winds and ferocious waves of sea storms could crush their ships or flip them over and sink them. Since the explorers didnt really know where they were going, they could easily get lost at sea. Finally, when the crew of a ship grew angry, they would sometimes have a mutiny a rebellion against the captain, which would cause chaos on a ship. Why would men want to make such dangerous trips?Reasons for Exploration One main motive was trade. Europe had long been interested in trading with Asia, so they could have access to the exotic spices that could keep food fresh and preserved. A problem arose when the Ottoman Turks conquered many lands between Europe and Asia. The Turks and Arabs had set up middlemen that Europeans would have to pay if they wanted Asian goods. Instead of paying these middlemen, some Europeans had the idea of finding new ways of getting to Asia over the oceans. They figured that if they sailed far enough west, they could reach China and India by wrapping around the globe. Besides seeking spices in Asia, the Europeans were also hoping to find precious metals, such as gold, in new lands. Another motive was that the European countries were competing with each other for new territory. Each of them wanted to claim new lands in making their country bigger and more powerful. They wanted to spread the glory of their nation by taking over new lands. When one country takes over or controls another it is called imperialism. Along with these conquerors went missionaries people sent to spread religious messages and convert others to their faith. In short, the reasons for European exploration can be summarized by the 3 Gs:God, Glory and Gold1. In the chart below, list 3 risks that came with exploring the oceans. On the other side, explain three benefits, rewards, or motivations for exploring.RISKSBENEFITS (MOTIVATIONS)a.a.b.b.c.c.2. What is imperialism?3. What are missionaries and what did they want?How was Exploration Made Possible?New Technologies Johann Guttenbergs invention of the printing press made maps and geographic information much more available. Since gunpowder had been introduced to the Europeans by the Arabs in the 1200s, Europeans developed new weapons that could keep their ships safe from invaders. Spanish and Portuguese ships were the first to perfect very powerful canons that made their ships deadly to any other on the sea. Naval technology was also extremely important. Mapmakers, or cartographers, created better maps and charts of the seas. Also, European sailors learned to use the magnetic compass to find better directions at sea. Europeans also built bigger and better ships. The Portuguese used ships whose sails, masts, and rudders allowed explorers to sail across or against the wind. Strong Monarchies European countries were also becoming ruled by monarchies (governments led by a king or queen) that built up their armies and navies and wanted to use them. The kings and queens of Europe were increasing their power and resources, and they could focus beyond their borders. They were willing to pay for the expensive and risky trips explorers were willing to make at sea, hoping they could make their kingdoms richer. 4.
