Answer:
4 and 10 - acute
2 is acute, but 3 is obtuse
8 and 12 - acute
6 and 12 - acute
1 is obtuse 2 is acute
15 and 11 are obtuse
9 is obtuse but 8 is acute
2 and 4 are acute.
Step-by-step explanation:
I believe this is correct.
A right angle is a perfect corner. Think of a square and look at the corner, it doesn't go farther or shorter when it hits a side if you know what I mean by that. An acute angle is shorter than a right angle, or stops before it can be called a right angle. An obtuse angle is bigger than a right angle, or ends after the right angle point. I hope what I have just said here helps you with future problems!! Good luck :))
The proportion 75/w = 150/100 can be used to find the whole 'w' when the part is 75. Will the 'w' be less than or greater than 75? Without solving, explain how you know. *
Answer:
w will be less than 75.
Step-by-step explanation:
Given the expression;
75/w = 150/100
We are to determine whether w is greater than or less than 75.
If you look at the right hand side of the expression, 150/100, you will see that the denominator is greater than the numerator. Due to the equality sign between the fractions, the same will be applicable to 75/w meaning that w will also be less than 75.

4 years
a. Interest:
b. Total:
Answer:
Interest earned: $150.85
Total amount: $850.86

(-inf, 1]
Step-by-step explanation:Personal comment
Sorry this took so long
In short, you had it flipped, always put your smallest value first and your largest value second.
Reason:
Interval notation is
[(minima, maxima)]
Which is basically saying the minimum and the maximum, and as such you always end up having the smallest value first.
Putting the reasoning together;
A negative is always less than a positive in practice, therefore, your negative infinity should go first.
Hope this helps :)

The actual area of the room will be 23.52 m².
What is Multiplication?
To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.
Given that;
Width of room = 4 cm
Length of room = 12 cm
And, The scale model uses a scale in which 2 centimeters represents 1.4 meters.
Now,
Since, The scale model uses a scale in which 2 centimeters represents 1.4 meters.
That is,
2 cm = 1.4 m
1 cm = 0.7 m
So, The width of room = 4 cm
= 4 x 0.7 m
= 2.8 m
And, The length of room = 12 cm
= 12 x 0.7 m
= 8.4 m
Thus, The actual area of room = Length x Width
= 8.4 x 2.8 m²
= 23.52 m²
Therefore, The actual area of the room will be 23.52 m².

To encourage new customers, a movie theater is offering different ways to pay for the movie.
Members pay a one time fee of $75 and then $2 per movie they watch.
Non-members pay $5.75 per movie they watch.
Answer:
Number of movies for equal wage = 20
Step-by-step explanation:
Assume;
Number of movies for equal wage = x
So,
75 + 2x = 5.75 x
3.75 x = 75
x = 75 / 3.75
x = 20
So,
Number of movies for equal wage = 20

Answer:
Width = 7, Length = 42
Step-by-step explanation:
Length is 6 times its width, means that it's the same number but times 6 so we'll use "x" for both length and width:
6x · x = 294
6x^2 = 294
divide both sides by 6
x^2 = 49
[tex]\sqrt{x^2}[/tex] = [tex]\sqrt{49}[/tex]
x = 7, width is 7 and length is 6(7) = 42

Titus is asked to prove hexagon FEDCBA is congruent to hexagon
F'E'D'C'B'A' in the graph below. Titus thinks that if he transforms hexagon
FEDCBA by (x, y) - (x + 16, y - 10) he can show the two figures are
congruent. Is he correct? Explain why or why not. If Titus is incorrect, what
series of transformations will correctly prove FEDCBA F'E'D'C' B'A'!
I need ASAPPPP
Answer: No, Titus is incorrect.
Step-by-step explanation: Two shapes are congruent when they have the same size and shape, but one is created of rotation, reversion or translation of the other.
So, hexagons FEDCBA and F'E'D'C'B'A' are congruent because they have the same size and shape, however they are reversed and translated from each other, i.e.:
Comparing the coordinates of both hexagons:
F (-6,6) → F' (6, -4)
A (-10,6) → A' (10,-4)
E (-4,4) → E' (4, -6)
B (-12,4) → B' (12, -6)
D (-6,2) → D' (6, -8)
C (-10,2) → C' (10, -8)
We notice that the transformation necessary to transform FEDCBA into F'E'D'C'B'A' is
multiply x-coordinate by (-1);subtract y-coordinate by 10;Therefore, it is (x,y) → ( -x, y-10).
So, Titus is incorrect about the transformations that prove the hexagons are congruent.

Two customers went to a sports shop to buy baseballs and gloves. Each Baseball cost the same amount and each glove costs the same amount.
- The first customer paid $60 for four baseballs and two gloves
- The second customer paid $84 for five baseballs and three gloves
What was the cost in dollars of each baseball?
Answer:
$6.00
Step-by-step explanation:
Using a system of equations, it is found that each baseball costs $6.
For our system, we are going to say that:
x is the cost of a baseball.y is the cost of a glove.The first customer paid $60 for four baseballs and two gloves, hence:
[tex]4x + 2y = 60[/tex]
Simplifying by 2:
[tex]2x + y = 30 \rightarrow y = 30 - 2x[/tex]
The second customer paid $84 for five baseballs and three gloves, hence:
[tex]5x + 3y = 84[/tex]
Since [tex]y = 30 - 2x[/tex]
[tex]5x + 3(30 - 2x) = 84[/tex]
[tex]5x + 90 - 6x = 84[/tex]
[tex]x = 6[/tex]
Each baseball costs $6.

Adam has two brothers, Ben and Chris, and one sister, Daisy. On any given day, Ben calls Adam with Probability 0.3, Chris calls Adam with Probability 0.4, and Daisy calls Adam with probability 0.7. let X be the number of siblings that call Adam tomorrow. Find the expectation of X.
Hint: Express X as the sum of suitable indicator random variables.
Answer:
The expected value of X = 1.4
Step-by-step explanation:
Given that:
The probability of Ben calling Chris = 0.3
The probability of Chris calling Adam = 0.4
The probability of Daisy calling Adam = 0.7
The probability distribution function can be calculated as follows:
P(X = 0) = P( nobody calls Adam)
= (1 - 0.3)×(1 - 0.4)×(1 - 0.7)
= 0.7 × 0.6 × 0.3
= 0.126
P(X = 1) = P(if only Ben call +if only Chris call + if only Daisy call)
P(X = 1) = 0.3 × (1-0.4) × (1-0.7) + (1-0.3) × 0.4 × (1 - 0.7) + (1 - 0.3) × (1-0.4) × 0.7
P(X = 1) = (0.3 × 0.6 × 0.3) + (0.7 × 0.4 × 0.3) + (0.7 × 0.6 × 0.7)
P(X = 1) = 0.432
P(X = 2) = P(if only Ben & Chris Call + if only Ben & Daisy call + if only Chris & Daisy call)
P(X = 2) = 0.3 × 0.4 × (1 - 0.7) + 0.3 × 0.7 × (1 - 0.4) + (1 - 0.3) × 0.4 × 0.7
P(X = 2) = ( 0.3 × 0.4 × 0.3 ) + (0.3 × 0.7 × 0.6) + (0.7 × 0.4 × 0.7)
P(X = 2) = 0.358
P(X = 3) = P(i.e. all three call) =0.3 × 0.4 × 0.7 = 0.084
Therefore; the expected value of X is calculated by using the formula:
[tex]E(X) = \sum x P(X=x)[/tex]
E(X) = (0 × 0.126) + (1 × 0.432) + (2 × 0.358) + (3 × 0.084)
E(X) = 0 + 0.432 + 0.716 + 0.252
E(X) = 1.4
Thus, the expected value of X = 1.4
