How many angles do 5 triangles and 3 rectangles have?
(1) 7
(2) 17
(3)
18
(4) 27
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
What is the measure of each interior angle of Regular Polygon?
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)
degree
∴ each interior angle =
9
180(9−2)
degree
=20×7
=140

Beth has saved 60$ for a gaming system.This is 30% of the total amount she needs for gaming system.how much does the new gaming system cost?
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

Order the angles in each triangle from smallest to largest.
9514 1404 393
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.

An examination consists of multiple-choice questions, each having five possible answers. Linda estimates that she has probability 0.4 of knowing the answer to any question that may be asked. If she does not know the answer, she will guess, with conditional probability 1/5 of being correct.A. What is the 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?
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
What is the total surface area of the rectangular prism?
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

A function is shown below.
g(x)=19.60+1.74x
What is the value of g(30)?
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
What is a function?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

x = 6
The right triangle on the right side with sides x and y is also a 30-60-90 triangle.
The hypotenuse is twice the short leg.
x = 6
y = 2x
y = 12
2x + 45
(Will be marked brainlist)
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:
4744 ftStep-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
tan 34° = 3200 / xx = 3200 / tan 34°x = 4744The distance is 4744 ft
