Identify the similar triangles in the figure then find the value of X.
A. Write the similarity statement in the form of triangle~triangle.
B. What is the value of X.
Answers
Answer:
A. ∆ABD ~ ∆CDE
B. x ≈ 5.3
Step-by-step explanation:
A. The Acute Angle Similarity Theorem states that when an acute angle in one right triangle is congruent to a corresponding acute angle in another, both right triangles are said to be similar to each other.
<B ≅ <D (both are right angles)
<A ≅ C,
Therefore, ∆ABD ~ ∆CDE
B. Since ∆ABD ~ ∆CDE, corresponding sides would be proportional to each other. This means that:
DE/BD = CD/AB
Substitute:
6/8 = 4/x
Cross multiply
6*x = 4*8
6x = 32
6x/6 = 32/6
x ≈ 5.3 (nearest tenth)

Answer:
7.2
Step-by-step explanation:
To reach point D from point C, you need to add 4 to the x-value of point C and take away 6 from the y-value. These numbers are the sides of the hypothetical triangle.
The Pythagorean Theorem states that [tex]a^2+b^2=c^2[/tex]. If we plug the side lengths in for a and b, we get [tex]4^2 + 6^2 = c^2[/tex]. This can be simplified to [tex]16+36=c^2[/tex], or [tex]52 = c^2[/tex]. If we root both sides, we find that c is equal to [tex]\sqrt{52}[/tex], which is slightly more than 7, at around 7.2.

If A, B, and C represent three matrices of the same size and (A + B) + C = 0, then which statement is true?
Answers
Answer:
Statement c:
a₁₁ + ( b₁₁+ c₁₁ ) = 0
Step-by-step explanation:
The options are:
a: a₁₁ = 0 and b₁₁ = 0
b: a₁₁ - ( b₁₁ + c₁₁ ) = 0
c. a₁₁ + ( b₁₁+ c₁₁ ) = 0
d. a₁₁x( b₁₁ + c₁₁) = 0
We know that A, B, and C are matrices of the same size, so we can write:
[tex]A = \left[\begin{array}{ccc}a_{11}&a_{21}&...\\a_{21}&a_{22}&...\\...&...&...\end{array}\right][/tex]
[tex]B = \left[\begin{array}{ccc}b_{11}&b_{21}&...\\b_{21}&b_{22}&...\\...&...&...\end{array}\right][/tex]
[tex]C = \left[\begin{array}{ccc}c_{11}&c_{21}&...\\c_{21}&c_{22}&...\\...&...&...\end{array}\right][/tex]
And here we have the sum of matrices, remember that:
[tex]A + B = \left[\begin{array}{ccc}a_{11}&a_{21}&...\\a_{21}&a_{22}&...\\...&...&...\end{array}\right] + \left[\begin{array}{ccc}b_{11}&b_{21}&...\\b_{21}&b_{22}&...\\...&...&...\end{array}\right] = \left[\begin{array}{ccc}a_{11} + b_{11}&a_{21} + b_{12}&...\\a_{21} + b_{21}&a_{22} + a_{22}&...\\...&...&...\end{array}\right][/tex]
And we know that (A + B) + C = 0 (a matrix full of zeros)
then:
[tex]\left[\begin{array}{ccc}(a_{11} + b_{11}) + c_{11} &(a_{21} + b_{12}) + c_{12}&...\\(a_{21} + b_{21}) + c_{21}&(a_{22} + b_{22}) + c_{22}&...\\...&...&...\end{array}\right] = \left[\begin{array}{ccc}0&0&...\\0&...&...\\...&...&...\end{array}\right][/tex]
Then:
(a₁₁ + b₁₁ )+ c₁₁ = 0
These are real numbers, so we can rewrite this as:
a₁₁ + ( b₁₁+ c₁₁ ) = 0
Then statement c is the correct one.

C

g Suppose that the retail price of a product has a normal distribution with a mean of $37 and a standard deviation of $20. Approximately, what is the probability that the price grows beyond double the mean
Answers
Retail price of the product will be double its mean will have a prbability of 0.0401.
What is Normal Distribution ?An example of a continuous probability distribution is the normal distribution, in which the majority of data points cluster in the middle of the range while the remaining ones taper off symmetrically toward either extreme. The distribution's mean is another name for the center of the range.
A probability distribution that is symmetric around the mean is the normal distribution, sometimes referred to as the Gaussian distribution. It demonstrates that data that are close to the mean occur more frequently than data that are far from the mean. The normal distribution appears as a "bell curve" on a graph.
The value of the product considering = $37*2 = $74(x)
Mean = $37
Standard Deviation (SD)= $20
here z= [tex]\frac{x - mean}{SD}[/tex] = [tex]\frac{74 - 37}{20} = \frac{37}{20} = 1.75[/tex]
P(z>1.75) = 1 - [tex]\phi(1.75)[/tex] = 1 - .9599 = 0.0401
Retail price of the product will be double its mean will have a prbability of 0.0401.

A fish swims at an altitude of -20. 2 meters. A bird flies at an altitude of 38. 1 meters. Which animal is closer to sea level?
Answers
The fish is closer to sea level. Sea level is defined as the mean sea level, which is a fixed point of reference for measuring altitude.
The altitude of the fish is -20.2 meters, which is closer to sea level than the altitude of the bird at 38.1 meters. This means that the fish is closer to sea level than the bird. To explain further, sea level altitude is a point of reference that is used to measure the altitude of other objects. Sea level altitude is defined as the mean sea level which is a fixed point.
Therefore, when trying to determine which animal is closer to sea level, it is important to look at the altitude of both the fish and the bird. The altitude of the fish is -20.2 meters, which is closer to sea level than the altitude of the bird at 38.1 meters. This means that the fish is closer to sea level than the bird.

A large helium balloon is tethered to the ground by two taut lines. One line is 100 ft. Long and makes an 80 degree angle with the ground. The second line makes a 40 degree angle with the ground. How long is the second line?
Answers
The second line is 153ft long.
We are making a figure out of the given statment. Where we have the Triangle ABC and other two Triangle ADB and ADC inside Triangle ABC. Here Angle ADC = 80 degress and Angle ACD = 40 egress.
According to given statement and figure,
In triangle ABO, AD= 100 ft
Hence, BD/AD = Cos80
or, BD = (100 * Cos80)
or, BD = 17.36 ft
Now, AB/AD = Sin80
or, AB = (100* Sin 80)
or, AB = 98.48
Now, In case of triangle ABC
AB/AC = Sin40
or, AC = AB/ Sin 40
or, AC = 98.48/ Sin40
or, AC = 153.2 ft (nearly equal to 153 ft)
The second line is 153ft long.

Mrs. Read can knit one pair of children's mittens with a ball of yarn six inches in diameter. How many pairs of identical mittens can she knit with a ball of yarn twelve inches in diameter
Answers
She can knit total 8 pairs of identical mittens with a ball of yarn twelve inches in diameter
In the given question, Mrs. Read can knit one pair of children's mittens with a ball of yarn six inches in diameter.
We have to find how many pairs of identical mittens she can knit with a ball of yarn twelve inches in diameter.
The radius of a ball of yarn six inches in diameter is
r = 6/2 = 3 inches
The radius of a ball of yarn twelve inches in diameter is
r = 12/2 = 6 inches
Now, the volume of the six inches yarn = [tex]\frac{4}{3} \pi r^3[/tex]
The volume of the six inches yarn = [tex]\frac{4}{3} \pi (3)^3[/tex]
The volume of the six inches yarn = 36π
Now, the volume of the twelve inches yarn = [tex]\frac{4}{3} \pi r^3[/tex]
The volume of the twelve inches yarn = [tex]\frac{4}{3} \pi (6)^3[/tex]
The volume of the twelve inches yarn = 288π
Now we finding the numbers of pairs of identical mittens she can knit with a ball of yarn twelve inches in diameter
= 288π/36π
= 8
Hence, she can knit total 8 pairs of identical mittens with a ball of yarn twelve inches in diameter.

Answers
The average time is 7.5. The average is calculated by dividing the total number of values in a given set by the sum of all the values in that set.
How to calculate average ?An average is a single number chosen to represent a group of numbers; it is often the sum of the numbers divided by the number of numbers in the group. Average The arithmetic mean is calculated by adding a set of numbers, dividing by their count, and then taking the result.
If every number in a list is the same number, then that number also serves as the average for the list. Every one of the diverse varieties of average shares this characteristic.
An average of the values in a sample of data can be used to define a mean. In other words, the arithmetic mean is another name for an average. A mean is a term used to describe the average.
Average = Sum / Count
Sum = 7.48 + 7.45 + 7.90 + 7.37 + 7.25 + 7.40 + 7.55 + 7.60

If the ratio between students to female adults is 7:6 while female adults to male adults is 4:1. What is the ratio of students to male adults?

Given
Ratio between students(s) to female(f) adults is 7:6
while ratio between female(f) to male(m) is 4:1
So, we can write
[tex]\Rightarrow \dfrac{s}{f}=\dfrac{7}{6}\quad \ldots(i)[/tex]
Also, we can write
[tex]\Rightarrow \dfrac{f}{m}=\dfrac{4}{1}\quad \ldots(ii)[/tex]
