Answer:
C= 41.45
Step-by-step explanation:
The circumference is given by C = 2[tex]\pi[/tex]r, since the diameter is 13.2 then the radius is half of that so r = 6.6
So C = 2(3.14) (6.6) =41.448

Tyee answered 126 questions correctly on his multiple choice history final that had a total of 200 problems. What percentage of questions did Tyee answer correctly on the final exam?
Answers
Answer:
63%
Step-by-step explanation:
To convert fractions to decimals:
Divide the top of the fraction by the bottom
he got [tex]\frac{126}{200}[/tex] so
[tex]126[/tex]÷[tex]200=0.63[/tex]
To convert decimals to percentages:
multiply by 100 and add a "%" sign.
[tex]0.63[/tex]×[tex]100[/tex]=[tex]63[/tex]%
The percentage of questions Tyee answered correctly is P = 63 %
What is Percentage?A percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, %
The difference between an exact value and an approximation to it is the approximation error in a data value. Either an absolute error or a relative error might be used to describe this error.
Percentage change is the difference between the measured value and the true value , as a percentage of the true value
Percentage change =( (| Measured Value - True Value |) / True Value ) x 100
Given data ,
Let the percentage of questions Tyee answered correctly be P
Now , the total number of questions = 200
The number of questions Tyee answered correctly = 126
So , P = number of questions Tyee answered correctly / total number of questions
On simplifying , we get
P = 126 / 200
P = 0.63
Therefore , the value of P is 0.63
Hence , the percentage is 63 %

Answer:
Step-by-step explanation:
Ok so basically 3 is 153 degrees and every line is 180 degrees, so 180-153=27. So 3 and 2 make a line, 2 is 27 degrees and 4 and 3 make a line so that makes 4 -27 degrees. 1 is vertical to 3 and if 2 and 4 are 27 degrees and makes the lines with the other angles that equal 27 degrees then 1 is also 153 degrees.

Answer:
Step-by-step explanation:
d is on a line with s so they are supplementary d+80 = 180 so d has to be 100
s and h are equal, therefore vertical angle x is also 80
Then 80 + 60 + y = 180 since they are on a straight line so y=40

A. 52
B. 50
C.90
D. 92
Answers
The value of x is 50 because, in a quadrilateral, the sum of the opposite angles is equal to 180 degrees. option (B) is correct.
What is quadrilateral?
It is defined as the four-sided polygon in geometry having four edges and four corners and two pairs of congruent sides.
We have:
In the diagram below, OP is circumscribed about quadrilateral ABCD.
In a quadrilateral, the sum of the opposite angles is equal to 180 degree
x + 20 + 110 = 180
x + 130 = 180
x = 50
Thus, the value of x is 50 because, in a quadrilateral, the sum of the opposite angles is equal to 180 degrees. option (B) is correct.
