Answer:

Step-by-step explanation:

Consider the angle of depression is same as the angle between horizontal line on the ground and the direct line from the plane to the airport (alternate interior angles).

Use tangent to find the missing length.

tan = opposite / adjacent

The distance is 4744  ft

Answer:

$200

Step-by-step explanation:

30% = $60

divide both sides of the equation by 3:

10% = $20

multiply both sides by 10:

100% = $200

Answer:

  B: L, M, N

Step-by-step explanation:

The sides are listed from shortest to longest. The angles opposite these sides will be in order smallest to largest. The name of the opposite angle is the vertex whose name is missing from the side's name.

MN is opposite angle L, the smallest

LN is opposite angle M, the middle-size

LM is opposite angle N, the largest.

Smallest to largest, the angles are ∠L, ∠M, ∠N.

Answer:

g(30) = 71.8

Step-by-step explanation:

g(30) = 19.6 + 1.74(30)

The value of the g(30) is 71.8 if the function is g(x) = 19.60 + 1.74x

It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.

We have a function:

g(x)=19.60+1.74x

Plug x = 30

g(30) = 19.60+1.74(30)

g(30) = 19.60 + 52.2

g(30) = 71.8

Thus, the value of the g(30) is 71.8 if the function is g(x) = 19.60 + 1.74x

Answer:

a. 0.52 = 52% probability that Linda gives the correct answer to a question.

b. 0.7692 = 76.92% probability that Linda knows the answer

Step-by-step explanation:

Conditional Probability

We use the conditional probability formula to solve this question. It is

[tex]P(B|A) = \frac{P(A \cap B)}{P(A)}[/tex]

In which

P(B|A) is the probability of event B happening, given that A happened.

[tex]P(A \cap B)[/tex] is the probability of both A and B happening.

P(A) is the probability of A happening.

In this question:

Event A: Supplies the correct answer:

Event B: Knows the answer

A. What is the probability that Linda gives the correct answer to a question?

0.4(knows the answer)

1/5 = 0.2 of 1 - 0.4 = 0.6(guesses the answer). So

[tex]P(A) = 0.4 + 0.2*0.6 = 0.52[/tex]

0.52 = 52% probability that Linda gives the correct answer to a question.

B. What is the conditional probability that Linda knows the answer, given that she supplies the correct answer?

Intersection of events A and B is knowing the answer and giving the correct answer, which means that [tex]P(A \cap B) = 0.4[/tex]

The desired probability is:

[tex]P(B|A) = \frac{P(A \cap B)}{P(A)} = \frac{0.4}{0.52} = 0.7692[/tex]

0.7692 = 76.92% probability that Linda knows the answer

Answer:

286.5

Step-by-step explanation:

(3 x 7.5) x 2 = 45

(11.5 x 3) x 2 = 69

(11.5 x 7.5) x 2 = 172.5

45 + 69 + 172.5 = 286.5

Answer:

All students in each grade

Answer:

x = 45°

Step-by-step explanation:

We know that (2x + 45)° and x° are adjacent angles, so they add up to 180°.

(2x + 45) + x = 180

3x + 45 = 180

3x = 180 - 45

3x = 135

x = [tex]\frac{135}{3}[/tex]

x = 45°

Answer:

31

Step-by-step explanation:

divide 124 by 4

x=124

Answer:

x=31

Step-by-step explanation:

Divide both sides of the equation by the same term

4x/4 = 124/4

Then you have to divide the numbers.

x= 124/4

x= 31

Answer:

27

Explanation:

5 * 3 = 15 (5 triangles with 3 angles each)

3 * 4 = 12 (3 rectangles with 4 angles each)

15 + 12 = 27

Answer:

the answer is 27 because a triangle has 3 sides so multiply 3 tomes 5 because of how many triandles and then the same with the rectangle that has 4 sides then multiply by 3 because of the number of triangles you have

Answer:

A regular polygon is a flat shape whose sides are all equal and whose angles are all equal. The formula for finding the sum of the measure of the interior angles is (n - 2) * 180. To find the measure of one interior angle, we take that formula and divide by the number of sides n: (n - 2) * 180 / n.

Step-by-step explanation:

140

∘

Each interior angle of regular polygon of n sides is given by  

n

180(n−2)

∴ each interior angle =
