Pentagon ABCDE ~ LMNOP. Find the value of x and the measure of Lc.
The value of x is 6 and the measure of ∠C is 86 degrees
How to solve for x and the measure of c?The complete question is added as an attachment
Given that:

This gives
8 : 6 = 12 : x
Express as fraction
6/8 = x/12
Multiply both sides by 12
12 * 6/8 = x
Evaluate
9 = x
Rewrite as
x = 9
Also
ABCDE ~ LMNOP implies that the corresponding angles are equal

Hey I appreciate the help thank you
Answer:
60 degrees
Step-by-step explanation:
The sum of the interior angles of a triangle are 180. The bottom triangle give you two of the angle measurements (43 and 35) Take 180 - 43 -35 = 102. Angle E is 102. Vertical angles are congruent so that mean that we can use that to find angle a. Again, the sum of the interior angles adds up to 180. 180 - 102 - 18 gives us the measurement of angle a (60)

Answer:
D. (4,0) and (-4,0)
C. there is one discontinuity at x=3
Step-by-step explanation:
Roots can be found by setting f(x)=0:
f(x)=(x^2-16)/(x^2-2x-3)
0=(x^2-16)/(x^2-2x-3), multiply both sides by x^2-2x-3 to get rid of the denominator
0=x^2-16, use difference of squares to factor it
0=(x+4)(x-4)
x=4,-4
Therefore the roots are (4,0) and (-4,0)
Discontinuities are when f(x) is undefined, and f(x) is undefined when something is divided by 0
Set the denominator equal to 0:
0=x^2-6x+9, use the form a^2 - 2ab + b^2 to factor
0=(x-3)^2
x=3
Therefore, there is a discontinuity at x=3

What is Binomial Distribution in Probability?
Assume that n independent replications of a random experiment with exactly two outcomes are performed. Success has a probability of [tex]p[/tex], while failure has a probability of [tex]q[/tex].

Answer:
[tex]y = \frac{1}{4} x + 9[/tex]
Step-by-step explanation:
All lines take the form
[tex]y = mx + c[/tex]
Where m is the gradient (or slope), and c is the y-intercept. To find the gradient if a line perpendicular to another, we must find the negative reciprocal of the other line. The gradient of the line given is -4, so our negative reciprocal is 1/4.
To find our y-intercept, we must find the point where the line crosses the y-axis (in other words, when the X coordinate is 0). Helpfully, the coordinate given is already at this point, so we can simply take the y coordinate from here, and we know our y-intercept is 9. Putting this altogether, our equation is:

Lowest common multiple of 12, 18,56
Answer: The lowest common multiple of 12, 18, and 56 would be 504. Why? Well, see below for an explanation!
Step-by-step explanation: What is the lcm? Well, the lcm of two or more numbers is the lowest possible number that each number has in common as a multiple. Because we are dealing with large numbers, we can tell that the lcm will be a multiple of these numbers times at least 5. I multiplied all the numbers by 10, and it was too large and did not work. However, I backed up and tried 9.
56 x 9 = 504.
Why is this acceptable? Well, this is acceptable because I found that 504 can be divided by 12 and 18 both to get a whole number.
504 divided by 18 equals 28.
504 divided by 12 equals 42.
Using this principle, we will find that 504 is the lowest number that 12, 18, and 56 have in common.
Your final answer: 504 is the lowest common denominator. If you need extra help, let me know and I will gladly assist you.

Pollsters are concerned about declining levels of cooperation among persons contacted in surveys. A pollster contacts 90 people in the 18-21 age bracket and finds that 76 of them respond and 14 refuse to respond. When 263 people in the 22-29 age bracket are contacted, 240 respond and 23 refuse to respond. Assume that 1 of the 353 people is randomly selected. Find the probability of getting someone in the 22-29 age bracket or someone who agreed to respond.
The probability of getting someone in the 22-29 age bracket or someone who agreed to respond is 0.96.
What is probability?The rate of possible outcomes to the total outcomes is said to be the probability.
P(E) = n(E)/n(S)
E - event and S -sample space
we have,
P(A or B) = P(A) + P(B) - P(A and B)
Calculation:It is given that,
Pollsters are concerned about declining levels of cooperation among persons contacted in surveys.
The data is listed below:
(Age group) Response - agreed Response - refused Total
18-21 76 14 90
22-29 240 23 263
Total 316 37 353
So, consider the required events
Age group (22-29) as A and someone who agreed to respond as B
Thus, the probabilities are calculated as below:
P(A) = n(A)/n(S) = 263/353
P(B) = n(B)/n(S) = 316/353
P(A and B) = n(A and B)/n(S) = 240/353
Substituting all these in the formula we get,
P(A or B) = P(A) + P(B) - P(A and B)
= 263/353 + 316/353 - 240/353
= 339/353
= 0.96
Therefore, the required probability is 0.96.

Calculate the total amount invested by summing up all the values of the investment.
Total = 50,000
Calculate the weight of each investment. For WOOPS, weight = 5000 / 50000 = 10% and so on.
Now, Expected Return = sum of weight x Returns = 10% x 0.14 + 20% x 0.16 + ... + 18%x 0.18 = 16.01%
b) Similarly,
Beta of the portfolio = sum of weight x beta = 10% x 0.6 + 20% x 0.8 + ... + 18% x 0.18 = 0.7605
c) Portfolio has less systematic risk as the beta for the average market is 1, which is above the portfolio
d) Using CAPM, Return = Rf + beta x (Rm - Rf) = 4% + 0.7605 x (14% - 4%) = 11.605%
To calculate the expected return of a portfolio, the investor needs to know the expected return of each security in the portfolio and the total weight of each security in the portfolio. This means that investors need to sum the weighted averages of the expected returns (RoRs) of each security.
Investors are based on estimates of the expected rate of return on securities, assuming that what has proven to be true in the past will be true in the future. Investors do not use the structural view of the market to calculate the expected return. Instead, it determines the weight of each security in the portfolio by dividing the value of each security by the total value of the security.

Answer:
B.) 54π units²
Step-by-step explanation:
First, we need to find the height of the cone. We can do this using the Pythagreom Theorem.
a² + b² = c² <----- Pythagreom Theorem
3² + b² = 15² <----- Insert side lengths
9 + b² = 225 <----- Solve 3² and 15²
b² = 216 <----- Subtract 9 from both sides
b = 14.7 units <---- Take square root of 216
Now, we can use the surface area of a right cone equation to find the final answer.
r = 3 units
h = 14.7 units
SA = πr(r + √(h² + r²)) <----- Surface Area equation
SA = π(3)(3 + √(14.7² + 3²)) <----- Insert values
SA = π(3)(3 + √(216 + 9)) <----- Solve 14.7² and 3²
SA = π(3)(3 + √225) <----- Add 216 and 9
SA = π(3)(3 + 15) <----- Take square root of 225
SA = π(3)(18) <----- Add 3 and 15
SA = 54π units² <----- Multiply 3 and 18

find a linear and an exponential equation that matches f(2)=12 and f(4)=48
The exponential equation that matches the coordinate is 3(2)^x while the linear equation is y = 6x
Exponential equationThe standard exponential equation is expressed as y= ab^x
where
a is the base
x is the exponent
Given the coordinates (2, 12) and (4, 48)
12 = ab^2
48 = ab^4
Find the ratio
4 = b^2
b = 2
Sice ab^2 = 12
4a = 12
a = 3
The exponential equation that matches the coordinate is 3(2)^x

Se vendieron un total de 430 boletos para la obra de teatro escolar. Los boletos eran o de adulto o de estudiante. Se vendieron 70 boletos de estudiante menos que boletos de adulto. ¿Cuántos boletos de adulto fueron vendidos?
Resolviendo un sistema de ecuaciones, veremos que se vendieron 250 boletos de adulto.
¿Cuántos boletos de adulto fueron vendidos?
Definamos las variables:
x = boletos de adulto vendidos.y = boletos de estudiantes vendidos.Se vendieron un total de 430 boletos, entonces:
x + y = 430
Y se vendieron 70 boletos de estudiante menos que boletos de adulto:
y = x - 70
Tenemos el sistema de ecuaciones:
x + y = 430
y = x - 70
Para resolverlo, podemos reemplazar la segunda ecuación en la primera:
x + y = 430
x + (x - 70) = 430
2x = 430 + 70 = 500
x = 500/2 = 250
Se vendieron 250 boletos de adulto.
