Answer:
Suppose that we have a circle of radius R.
The total perimeter of this circle will be:
P = 2*pi*R
Where pi = 3.14159...
Now, if we have a section of this circle with an angle A, the "chord" of this section will be:
C = (A/360°)*2*pi*R.
Where you can see that if A = 360° (so the section is the whole circle) the chord is equal to the perimeter.
In this particular case, the chord is equal to the radius of the circle, then we get:
C = R = (A/360°)*2*pi*R
We need to solve this for A.
R = (A/360°)*2*pi*R
We can divide both sides by R to get:
1 = (A/360°)*2*pi
Now we need to isolate A.
(360°/2*pi) = A = 57.3°
This would be the angle in the minor arc.
And the angle for the mayor arc would be the difference between the angle for a whole circle (360°) and the angle of this section (57.3°)
The angle for the major arc is:
A = 360° - 57.3° = 302.7°

Which graph shows the relationship between the number of tigers and the total number of square feet of space?
Answers
Answer:
Graph A shows the relationship between the number of tigers and the total number of square feet of space as expressed in the equation.
Step-by-step explanation:
Answer: Graph A shows the relationship between the number of tigers and the total number of square feet of space and here is my proof.
Step-by-step explanation: square feet is supposed to be in the thousands and graph A is one of the only ones that show that. Also the number of tigers are ofc single numbers so that makes the numbers below 1,2,3,4, and 5 and the numbers for square feet are 1,000, 2,000, 3,000, 4,000, and 5,000.

if the arithmetic mean of 5 and c is 11,what is the value of c?
Answers
Answer:
c = 17
Step-by-step explanation:
(c + 5) : 2 = 11
c + 5 = 22
c = 17
If the arithmetic mean of 5 and c is 11, the value of c is 17.
What is the interpretation of average?Arithmetic mean is the best central measure available for representing the values of a data set. It is also called average of the values of the considered data set.
It serves as predicted value(in case no other information of the data is available) of that data set.
Average provides ill information in case of skewed data.
If the arithmetic mean of 5 and c is 11, then the value of c.
(c + 5) : 2 = 11
c + 5 = 22
c = 17
Hence, the value of c is 17.

If the diameter of a circle is increased by 6 cm, what is the increase in the circumference of the circle?
Answers
Answer:
The circumference will be larger by 3 cm.
Step-by-step explanation:
We know that the circumference of a circle is C = 2πr, where r is the radius. The circumference can also be expressed as C = 2π [tex]\frac{d}{2}[/tex], where d is the diameter (since the radius is half the diameter).
So, if we increase the diameter by 6:
C = 2π [tex]\frac{(d+6)}{2}[/tex]
C = 2π [tex]\frac{d}{2}+\frac{6}{2}[/tex]
C = 2π [tex]\frac{d}{2}[/tex] + 3
If we compare this to the original equation, C = 2π [tex]\frac{d}{2}[/tex], we see that if we increase the diameter by 6 cm, the circumference will be larger by 3 cm.

1: height is 28/3 (9 1/3)
2: Base is 25/2 (12 1/2)
3: Height is 59/4 (14 3/4)
Step-by-step explanation:
Since the formula to find the area of a pallelogram is A=base × height
I divided the area by either the Base or the height (depending which one the problem had gave me)
Therefore 147 will be divided by 15 3/4.
Then 140 5/8 will be divided by 11 1/4.
Finally 151 3/16 would be divided by 10 1/4.

Equation of line: y - 44 = -3(x - 12)
The equation for the relationship between temperature and time is
T = 44 - 3x
Where x is the number of hours and T is the temperature.
What is an expression?An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example: 2 + 3x + 4y = 7 is an expression.
We have,
The temperature at 12 am = 44°
The temperature after 8 hours = 20°
Now,
The temperature drops steadily.
This means,
Temperature drops in an hour.
= (44 - 20) / 8
= 24/8
= 3°
The equation for the temperature after x hours.
= 44 - 3x
Thus,
The steady temperature drop in an hour is 3°.
