1. is a central angle, therefore, the arc will have the same measurement as the angle. Set the equation:
Arc = Central Angle
2x - 7 = 47
Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.
First, add 7 to both sides of the equation:
2x - 7 (+7) = 47 (+7)
2x = 47 + 7
2x = 54
Next, divide 2 from both sides of the equation:
(2x)/2 = (54)/2
x = 54/2 = 27
27 is your answer.
2. is a inscribed angle, meaning that the angle measurement will be half of the arc. Set the equation:
212 = 2(13x - 24)
Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.
First, divide 2 from both sides of the equation:
(212)/2 = (2(13x - 24))/2
106 = 13x - 24
Next, add 24 to both sides of the equation:
106 (+24) = 13x - 24 (+24)
106 + 24 = 13x
130 = 13x
Finally, divide 13 from both sides of the equation:
(130)/13 = (13x)/13
x = 130/13
x = 10
10 is your answer.
3. is a central angle. The arc and the angle will, therefore, have the same measurement:
137 = 3x + 5
First, subtract 5 from both sides of the equation:
137 (-5) = 3x + 5 (-5)
137 - 5 = 3x
132 = 3x
Next, divide 3 from both sides of the equation to isolate the variable, x:
(132)/3 = (3x)/3
x = 132/3 = 44
44 is your answer.
4. is a inscribed angle. The arc will be twice the measurement of the angle.
86 = 2(2x + 3)
First, isolate the variable x by dividing 2 from both sides of the equation.
(86)/2 = (2(2x + 3)/2
43 = 2x + 3
Next, subtract 3 from both sides of the equation:
43 (-3) = 2x + 3 (-3)
40 = 2x
Finally, divide 2 from both sides of the equation:
(40)/2 = (2x)/2
x = 40/2 = 20
20 is your answer.

it's recorded that out of 1000 people, 762 wear the corrective lenses.
just divide 762 from 1000 and multiply that result by 100.
762/ 1000 = .762
.762 x 100 = ? %
which is 76.2 %
so, we predict that 76.2% of Americans would wear corrective lenses.

Answers
Answer:
y = 10
Step-by-step explanation:
Using the sine ratio in the right triangle and the exact value
sin30° = [tex]\frac{1}{2}[/tex] , then
sin30° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{y}{20}[/tex] = [tex]\frac{1}{2}[/tex] ( cross- multiply )
2y = 20 ( divide both sides by 2 )
y = 10

The National Health Survey uses household interviews to describe the health-related habits of U.S. adults. From these interviews they estimate population parameters associated with behaviors such as alcohol consumption, cigarette smoking, and hours of sleep for all U.S. adults. In the 2005-2007 report, they estimated that 30% of all current smokers started smoking before the age of 16. We randomly select a sample of 100 smokers and calculate the proportion who started smoking before the age of 16.

Based on your simulation, what is the average amount of error you expect to see in the sample proportions in this situation?
answer : 0.0458
Step-by-step explanation:
In 2005 - 2007 : 30% of all current smokers started smoking before the age of 16
n ( sample size ) = 100 smokers
The average amount of error expected can be calculated as
[tex]\sqrt{pq/n}[/tex] = [tex]\sqrt{0.3*0.7/100}[/tex] = 0.0458
where : p = 0.3
q = 0.7
n = 100
The solids are similar. Find the surface area of the red solid.
Answers
Answer:
756
Step-by-step explanation:
The ratio of areas is the square of the scale factor.
First, we find the scale factor from the blue solid to the red solid.
scale factor = 6/4 = 3/2
The ratio of areas is the square of the scale factor:
ratio of areas = (3/2)^2 = 9/4
volume of red solid = volume of blue solid * ratio of areas
volume of red solid = 336 m^2 * 9/4 = 756 m^2
Answer: S = 756 m^2
