pleaseeeeeeee helpppp!!! Find the missing angel measurements of angle 1,4,7,10,13 please consider how many degrees are in a triangle while solving this please please help, this is for geometry
Answers
Answer: ∠1 = 52°, ∠4 = 40°, ∠7 = 100°, ∠10 = 49°, ∠13 = 65°
Step-by-step explanation:
There are three formulas you need to find the angles. Each formula is based on where the vertex lies.
On the circle: Measure of the angle = (1/2) the arc
∠4 = (1/2)°80 ∠10 = (1/2)(18° + 80°) ∠13 = (1/2)130°
= 40° = (1/2)98° = 65°
= 49°
Inside the circle: (1/2) Sum of the Big arc and Little Arc
∠7 = (1/2) (130° + 70°)
= (1/2)200°
= 100°
Outside the circle: (1/2) Difference of the Big arc and Little Arc
∠1 = (1/2)[(62° + 130°) - (70° + 18°)]
= (1/2) (192° - 88°)
= (1/2)104°
= 52°
Below is the solution for ALL of the angles

Answers
Answer:
$7.89
Step-by-step explanation:
There are 36 possible outcomes when rolling two dice.
The sum will be odd if the first die is odd and the second is even or if the second is odd and the first is even. The probability of an odd sum is:
[tex]P(odd)=\frac{3}{6} *\frac{3}{6} +\frac{3}{6} *\frac{3}{6}\\P(odd)=0.5[/tex]
There is a probability of 1 in 2 of winning $10.
There are 8 ways to get a sum of 4 or 8 (1,3; 3,1; 2,2; 5,3; 3,5; 2,6; 6,2; 4,4). There is a probability of 8 in 36 or 2 in 9 of winning $5.
There are 2 ways to get a sum of 2 or 12 (1,1; 6,6). There is a probability of 2 in 36 or 1 in 18 of winning $50.
Any other outcome will not payout any amount.
The expected value is the sum of all possible payouts multiplied by their likelihood (including a 100% chance of paying $1 to play).
[tex]E=-1+10*\frac{1}{2} +5*\frac{2}{9}+50*\frac{1}{18}\\E=\$7.89[/tex]
The expected value is $7.89.

I NEED HELP PLEASE! THANKS :)
Answers
Answer:
A
Step-by-step explanation:
First, let's do the difference of two squares:
[tex](1-cos^4(\theta))=(1-cos^2(\theta))(1+cos^2(\theta))[/tex]
Note that [tex]sin^2(\theta)=1-cos^2(\theta)[/tex] (Pythagorean Identity)
Thus, we can substitute:
[tex]sin^2(\theta)(1+cos^2(\theta))[/tex]
Now, and I'm serious, you just have to use your creativity. After a while, you will find that:
[tex]sin^2(\theta)+cos^2(\theta)=1[/tex]
So:
[tex]1+sin^2(\theta)+cos^2(\theta)=1+1[/tex]
Thus, we have [tex]1+cos^2(\theta)=2-sin^2(\theta)[/tex]
Now, we can substitute:
[tex]sin^2(\theta)(2-sin^2(\theta))=2sin^2(\theta)-sin^4(\theta)[/tex]
Chris had a piece of rope that was 15 inches long. He wanted to cut the rope into pieces that were each 3/5 of an inch long. How many pieces of rope can he cut from the original rope?
Answers
Hey there! :)
Answer:
25 pieces.
Step-by-step explanation:
To solve for the amount of pieces that can be cut, we must divide fractions:
15 ÷ 3/5 = x
When dividing fractions, you must multiply by the reciprocal. Therefore:
[tex]\frac{15}{1}* \frac{5}{3} = \frac{75}{3} = 25[/tex]
Therefore, 25 pieces can be cut.
Answer:
25 3/5 inch long pieces
Step-by-step explanation:
If you have 15 inches and you cut it into less than inch pieces, you know for sure that it will be more than 15 but less than 30 because the peices are more than half an inch.
to find the answer, you divide 15 by 3/5 because each piece is 3/5 inches long
when you put this into a calculator 15/(3/5) you will get the answer 25.
So, ANSWER = 25 pieces of rope that are 3/5 inches long

Tim wants to build a rectangular fence around his yard. He has 42 feet of fencing. If he wants the length to be twice the width, what is the largest possible length? Write an equation and solve.
Answers
Answer:
Rectangular fence dimensions:
x = 14 ft
w = 7 ft
A = 98 ft²
Step-by-step explanation:
Rectangular fence dimensions:
x length and w width
Then x = 2*w ⇒ w = x/2
Perimeter is
p = 2*x + 2*w
p = 2*x + 2* x/2
p = 2*x + x
3*x = 42
x = 14 ft and w = 14/2 ⇒ w = 7 ft
Bill drives 2 hours at a speed of 60 mph (miles per hour). Afterwards, he drives for 4 hours at a speed of 75 mph. What is his average
speed over the 6 hours that he spent driving
Answers
Answer:
70 mph
Step-by-step explanation:
Here we want to calculate average speed
Mathematically, average speed = Total distance/Total time
Kindly recall distance = speed * time
for the first part;
We have: 60 * 2 = 120 miles
For the second: 4 * 75 = 300 miles
Average speed = (300 + 120)/(4 + 2) = 420/6 = 70 mph

Read the excerpt from A Vindication of the Rights of Woman. Let there be then no coercion established in society, and the common law of gravity prevailing, the sexes will fall into their proper places. And, now that more equitable laws are forming your citizens, marriage may become more sacred: your young men may choose wives from motives of affection, and your maidens allow love to root out vanity. What is the central idea of the excerpt? In proper societies, there are strict laws about marriage. Men will fall into submission when their wives are well educated. In equal roles, men and women will establish more meaningful marriages. Men and women should marry for reasons other than love and affection.
Answers
Answer:
In equal roles, men and women will establish more meaningful marriages.
Step-by-step explanation:
Marry Wollstonecraft in her feminist philosophy "A Vindication of the Rights of Woman" had projected the idea of equalizing the rights of men and women. She builds her argument against the theorists who do not consider education to be important for the female gender of the society. She presents her point by giving instances of how the education of women is indirectly related to the upliftment of the entire society. Wollstonecraft urges for equal fundamental rights to be shared by both men and women. An educated woman not just helps to become a good 'companion' of her husband but also raises her children in an efficient way.

Answer:
the angle itself is 39
Step-by-step explanation:
first the angle 132 is apart of line segment jer so 180-132=48
48+93=141
180-141=39
Answer:
39º
Step-by-step explanation:
Once the angle 132º and angle ∠BER are supplementary angles (add up to 180 degrees), ∠BER = 48º.
Also, once the sum of a triangle's interior angles is 180º:
∠BER + 93º + (9x+3)º = 180º
48º + 93º + 9x + 3º = 180º
144º + 9x = 180º
9x = 36º
x = 4º
Therefore, the angle ∠EBR (green) is equal to 39º
For what values (cases) of the variables the expression does not exist: [tex]\frac{3}{4y+2}[/tex]

Answer:
y = - [tex]\frac{1}{2}[/tex]
Step-by-step explanation:
Given
[tex]\frac{3}{4y+2}[/tex]
The denominator of the expression cannot be zero as this would make it undefined. Equating the denominator to zero and solving gives the value that y cannot be, that is
4y + 2 = 0 ( subtract 2 from both sides )
4y = - 2 ( divide both sides by 4 )
y = [tex]\frac{-2}{4}[/tex] = - [tex]\frac{1}{2}[/tex] ← excluded value

Jordan is calculating the slope of the trend line in the scatterplot below. On a coordinate plane, a trend line has a positive slope. How can Jordan use the plot to check the reasonableness of his answer? His slope should be positive because the coordinates of all the plotted points are positive. His slope should be positive because the trend line is slanted up to the right. His slope should be negative because there are plotted points not on the line. His slope should be negative because the x-coordinate of each plotted point is less than the y-coordinate.
Answers
Answer:
His slope should be positive because the trend line is slanted up to the right.
Step-by-step explanation:
Assume the graph is like the one below.
The line is slanted up and to the right, so the slope is positive.
A is wrong. The points could all be positive and have a negative slope.
C is wrong. Most of the points are not on the line but the slope is still positive.
D is wrong. The slope does not depend on the values of x and y. It depends on the values of Δx and Δy.
Answer:
Step-by-step His slope should be positive because the trend line is slanted up to the right.

Julio’s rotation maps point K(–6, 9) to K’(9, 6). Which describes the rotation? A. 90 degrees clockwise rotation B. 180 degrees rotation C. 90 degrees counterclockwise rotation D. 270 degrees clockwise rotation
Answers
Answer:
The correct option is;
A. 90 degrees clockwise rotation
Step-by-step explanation:
From the given information, we have;
The coordinates of the pre-image is K(-6, 9)
The coordinates of the image is k'(9, 6) which is similar to a transformation of a pre-image of (x, y) to an image of (y, -x)
The transformation from (x, y) to (y, -x) can be obtained from either;
1) A rotation of 90° (clock wise)
2) A rotation of 270° counter clockwise
Therefore, the correct option that maps K(-6, 9) to K'(9, 6) is a 90 degrees clockwise rotation.

Answers
Answer:

Step-by-step explanation:
The Triangle Inequality Theorem lets us know that the sum of the two shortest sides of the triangle must be greater than the third side of the triangle.
In both A and D, the sum of the shortest two sides are equal to, not greater than the third side, so they will not form a triangle.
In B, 12+20 is 32, which is greater than 25. And in C, 18+24 is 42, which is greater than 30, so they both will form a triangle.
Using the Pythagorean Theorem, it is found that possible side lengths of a right triangle are given by:
c. 18 cm, 24 cm, 30 cm
What is the Pythagorean Theorem?The Pythagorean Theorem relates the length of the legs [tex]l_1[/tex] and [tex]l_2[/tex] of a right triangle with the length of the hypotenuse h, according to the following equation:
[tex]h^2 = l_1^2 + l_2^2[/tex]
The length of the hypotenuse is always greater than the length of the legs. The Pythagorean Theorem has to hold true, which holds only for option C, as:
18² + 24² = 30²
900 = 900
