a = 64b = 112c = 78d = 88==========================================
Explanation:
The 102 inscribed angle cuts off the arc that's composed of the 140 and 'a'.
Due to the inscribed angle theorem, we know that a+140 is exactly equal to twice that of 102.
This means,
a+140 = 2*102
a+140 = 204
a = 204-140
a = 64
-----------------
The angles 102 and c are inscribed angles opposite one another. They add to 180. This is true for any inscribed quadrilateral.
c+102 = 180
c = 180-102
c = 78
-----------------
Another useful rule is that the four angles of any quadrilateral always add to 360.
102+92+c+d = 360
102+92+78+d = 360
272+d = 360
d = 360-272
d = 88
-----------------
The inscribed angle d cuts off the arc a+b
This means 2d is the measure of a+b because of the inscribed angle theorem.
a+b = 2d
64+b = 2*88
64+b = 176
b = 176-64
b = 112

Thaddeus shakes his head as he pays $12.37 to the clerk for lunch. Complaining to a friend, Thaddeus says, “Do you realize that is 0.2% of my monthly income?” His friend replies, “I think you made a mistake. That should be 2%. You messed up on the decimal point.” (a) Assuming Thaddeus is not wrong, what is his monthly income? (b) If Thaddeus’ friend is correct, what is Thaddeus’ monthly income?
Answers
Answer:
a) If Thaddeus is not wrong, his monthly income is $6,185.
x/12.37 = 100/0.2
0.2x = 1237
x = 1237/0.2x
x = 6,185
b) If Thaddeus's friend is correct, Thaddeus's monthly income is $618.5
x/12.37 = 100/2
2x = 1237
x = 1237/2x
x = 618.5
If Thaddeus is not wrong, his monthly income is $6,185.
If Thaddeus's friend is correct, Thaddeus's monthly income is $618.5.
What is Algebra?A branch of mathematics known as algebra deals with symbols and the mathematical operations performed on them.
Variables are the name given to these symbols because they lack set values.
In order to determine the values, these symbols are also subjected to various addition, subtraction, multiplication, and division arithmetic operations.
Given:
Thaddeus shakes his head as he pays $12.37 to the clerk for lunch.
a) If Thaddeus is not wrong then let his income be x.
So, x/12.37 = 100/0.2
0.2x = 1237
x = 1237/0.2x
x = 6,185
b) If Thaddeus's friend is correct
x/12.37 = 100/2
2x = 1237
x = 1237/2x
x = 618.5

D. 99
Answers
The actual degree measure of arc KJ is 99 degrees
Circle geometryFrom the given informtion
arc KL = 12x+4
arc KJ = 8x-6
<E = 99 degrees
The equation required to get the value of "x" is given as:
12x + 4 + 8x - 6 + 99 = 360
20x + 97 = 360
20x = 360 - 97
20x = 263
x = 13.15
For the arcKL
arcKJ = 8(13.15) - 6
arcKJ = 99degrees

A local weather enthusiast wants to see if the last five summers have been warmer than normal for Eloy, Arizona. From the National Oceanic and Atmospheric Administration (NOAA), he knows the 30-year average for July was 90° with a standard deviation of 2. 1°. The last five summers recorded have an average of 93. 5°. If he uses a = 5%, which of the following would be valid based on the data he has gathered? He can conclude that the summers have been warmer than the 30-year average. He can conclude that the summers will continue to be warmer for the next 10 years. He does not have enough information to make a decision. The average for the last five years fits with the 30-year average.
Answers
For local weather of Eloy, Arizona, the average for the last five years fits with the 30-year average.
What is the standard deviation data?The standard deviation of the data is the half of the difference of the highest value and mean of the data set.
The 30-year average for July was 90°. The standard deviation for this average is 2.1°. Thus, the temperature is lie between the [tex]\pm 2.1[/tex] ranges around the 90° in the month of July.
Therefore, the range of the temperature is,
[tex]t=90-2.1=87.9^o\\t=90+2.1=92.1^o[/tex]
The last five summers recorded have an average of 93. 5° and the value of a is 5%. Thus, the reduction is,
[tex]t=92-92\times\dfrac{2.5}{100}\\t=89.70^o[/tex]
This value of temperature lies between the range of 87.9-92.1 degrees Celsius. Hence, the two average are probably the same.
Hence, for local weather of Eloy, Arizona, the average for the last five years fits with the 30-year average. Option D is correct.

The volume of a cone is 540pi
Work out the height,of the cone.
The radius is 9cm
Answers
Formula for volume of a cone = pi x r^2 x h/3
540pi = pi x 9^2 x h/3
Divide both sides by pi:
540= 9^2 x h/3
Simplify:
540 = 81 x h/3
Divide both sides by 81:
6 2/3 = h/3
Multiply both sides by 3
H = 20
the height is 20 cm
