In triangle def, if m∠d is (2x)°, m∠e is (3x − 2)°, and m∠f is (x + 8)°, then the value of x is 29.

A triangle is a three-sided polygon that consists of three edges and three vertices.

Triangle is DEF

if m∠d is (2x)°, m∠e is (3x − 2)°, and m∠f is (x 8)°

We need to find the value of x.

We know that the sum of three angles of triangle is 180 degrees

m∠d + m∠e + m∠f=180°

2x+3x-2+x+8= 180°

6x+6=180

Subtract 6 on both sides

6x=174

Divide by 6 on both sides.

x=174/6

x=29

Hence, the value of x is 29.

Answer: 55°

Step-by-step explanation: Let me know if you need an explanation.

Answer:

X = 55°

Step-by-step explanation:

X = 180° - ( 75 + 50)°

X = 180° - 125°

X = 55°

A) Sum of (Score) ΣX equal to 63 and (Mean)M equal to 7.

B) Sum of Score ΣX equal to 96.

C) On the other side of the seesaw, the sixth score must be one point below the mean.

D)The sample has 7 scores.

E) To get the mean for the combined sample, the scores for each sample added together are 6.

A) Here we have to calculate the sum of scores (ΣX),

Add all of the scores together:

8 + 2 + 5 + 7 + 12 + 9 + 11 + 3 + 6

= 63

We sum up all of the scores and divide by the total number of scores (in this example, 9), which gives us the mean (M):

M = ΣX / n

M = 63 / 9

M = 7

B)The following formula may be used to get the value of X when the sample size (n) is 12 and the mean (M) is 8.

ΣX = M x n

ΣX = 8 x 12 = 96

Therefore, ΣX = 96.

C) The sixth score would need to be one point below the mean to balance the total if we know that the first five scores are all one point above the mean. This is thus because, like a seesaw, the mean represents the point of equilibrium in a group of scores. The seesaw is skewed up on one side if five scores are above the mean; the only way to balance it out is to position the sixth score on the other side, one point below the mean.

D) The following formula may be used to get the total number of scores in a sample with a mean (M) of 8 and a sum (X) of 56 scores:

ΣX = M x n

56 = 8 x n

n = 7

Hence, The sample has 7 scores.

E) The sum of the scores for each sample must first be determined in order to get the mean for the combined sample:

First sample, n = 10, M = 8, and the following:

ΣX1 = M x n

ΣX1 = 8 x 10

ΣX1 = 80

Second sample with n = 5 and M = 2:

ΣX2 = M x n

ΣX2 = 2 x 5

ΣX2 = 10

We just put the two amounts together to obtain the combined sample's overall sum of scores (ΣX):

ΣX = ΣX1 + ΣX2

ΣX = 80 + 10

ΣX = 90

We divide the entire sum of scores by the total number of scores to determine the mean for the combined sample:

M = ΣX / n

M = 90 / (10 + 5)

M  = 6

Hence, six is the sample's overall mean.

A SSS (side-side-side) theorem is kind of Congruence rule where two triangles with three congruent sides. So, we can solve it by showing the congruency between two triangles.

Statement: Side-Side-Side (SSS) ,the congruence theorem states that two triangles are congruent if three of their sides are equal to the corresponding sides of the other triangle.

Proof: Given, AB = DE, BC = EF, AC = DF.

To prove: ΔABC ≅ ΔDEF.

We know that the three sides of both triangles are equal in size and length. With both triangles superimposed, DE is placed on AB, EF is placed on BC, and DF is placed on AC. That is, AB = DE, BC = EF, AC = DF. Therefore, we can say that ΔABC ≅ ΔDEF.

The language A = {0^(2n) | n ≥ 0}, consisting of strings of zeros that are multiples of two, is a regular language and can be described by a regular expression or recognized by a finite automaton.

The language A = {0^(2n) | n ≥ 0}, which contains all strings of zeros that are multiples of two, is a regular language.

A regular language can be recognized or generated by a regular expression, a finite automaton (e.g., deterministic finite automaton or non-deterministic finite automaton), or a regular grammar.

In this case, we can define a regular expression to describe the language A as follows: A = (00)*. This regular expression matches any number of repetitions of the string "00," which corresponds to the multiples of two.

Alternatively, we can construct a finite automaton that recognizes the language A. The finite automaton would have a single initial state with a self-loop on the input symbol "0," indicating that any number of zeros can be traversed, representing the multiples of two

Since the language A can be described by a regular expression or recognized by a finite automaton, we can conclude that it is a regular language.

We are given with the radius of the circular field,

\(r = 42 \: m\)

And, we have to find the perimeter of the field. Also, we have to find the length of the wire required to fence it with 5 rounds:

We know,

Perimeter of a circle = 2πr, where r is the radius of the circle, So let's find the perimeter by using this formula.

\(perimeter = 2\pi r\)

\(perimeter = 2 \times \dfrac{22}{7} \times \: 42 m\)

\(perimeter = 2 \times 22 \times 6 \: m\)

\(perimeter = \boxed{264 \: m}\)

Now, finding the length of the wire which is equals to 5 × Perimeter of the circular field.

\(length \: of \: wire = 264 \: m \times 5\)

\(length \: of \: wire = \boxed{1320 \: m}\)

Answer:

196 miles

Step-by-step explanation:

To find the distance that the bus drives, we can use the formula:

distance = rate x time

where rate is the average speed and time is the duration of the trip.

In this case, the average speed of the bus is 56 mph and the duration of the trip is 3 1/2 hours. However, it is easier to work with time in terms of a single unit, so let's convert 3 1/2 hours to 7/2 hours:

3 1/2 hours = (2 x 3) + 1/2 hours = 7/2 hours

Now we can plug in the values into the formula:

distance = rate x time

distance = 56 mph x 7/2 hours

We can simplify by multiplying 56 by 7 and then dividing by 2:

distance = (56 x 7) / 2 = 196 miles

The reasons why our bags would differ from the expected distribution are sampling error, measurement error, selection bias, quality control issues, human error, environmental factors and external factors

There are several reasons why the distribution of bags might differ from the expected distribution. Some possible causes include:

1. Sampling error: If the sample size of bags is small, the distribution of bags may not accurately reflect the overall population.

2. Measurement error: If the bags were not measured or counted correctly, the distribution may be affected.

3. Selection bias: If the bags were not selected randomly or if certain bags were excluded from the sample, the distribution may not reflect the true population.

4. Quality control issues: If there were issues with the production of the bags, such as variations in size or weight, the distribution may be affected.

5. Human error: If mistakes were made in the handling, counting, or measuring of the bags, the distribution may not be accurate.

6. Environmental factors: External factors, such as temperature, humidity, or transportation, could cause changes in the weight of bags.

Deposit $625 into a money market account with a 5% rate for 1 year would result in more money.

To do this, we make use of 1.50% interest rate

Here, we have:

Initial, a= 625

Rate, r = 1.5%

The exponential growth equation is

A(t) = a * (1 + r)^t

So, we have:

A(t) = 625 * (1 + 1.5%)^t

Evaluate

A(t) = 625 * 1.015^t

Hence, the exponential growth equation is A(t) = 625 * 1.015^t

Here, t = 25.

So, we have:

A(25) = 625 * 1.015^25

Evaluate

A(25) = 906.84

Hence, the value in 25 years is $906.84

#Investment A

a = 625

r = 1.5%

t = 5

So, we have:

A(5) = 625 * 1.015^5

Step-by-step explanation:

Answer:

The correct answer is x= - 3

Step-by-step explanation:

The function f(x) = 150,000(0.85)^x can be used to determine the number of tickets the Houston Ballet Company will sell over time. In this function, the 150,000 represents the initial number of tickets sold before any time has passed (when x = 0).

It serves as the starting point or baseline for the exponential decay of ticket sales over time. As x increases, the function evaluates the number of tickets sold at a particular time, where each subsequent value of x represents a subsequent unit of time (such as days, weeks, months, etc.). The term (0.85)^x represents the decay factor, as it is less than 1 (0.85). Thus, the function models a situation where ticket sales decrease exponentially over time from the initial value of 150,000.
