Step-by-step explanation:
a.
the arc angle AC = 180° (since this is a diameter).
the arc angle BC = 60°.
so,
arc angle AB = arc angle AC - arc angle BC = 120°.
b.
the exterior angle of a circle segment at the circle arc is half of the interior angle at the center of the same segment.
the angle A = arc angle BC / 2 = 30°.
c.
the same principle as in b.
the angle C = arc angle AB /2 = 60°.
d.
the arc angle AD = the angle at AOD (that is how arc angles are defined).
the angle AOD = the angle AOF.
the sum of all angles in a triangle is always 180°.
angle AOD = AOF = 180 - 90 - angle A = 60°.
e.
as explained, this is the same as the arc angle AD and therefore the same as d.
it is 60°.
f.
the arc angle CE = the arc angle AD = 60°.
remember, the angles of intersecting lines are the same (just side mirrored) on both sides of each line.
g.
the arc angle ABE = arc angle AB + arc angle BC +
+ arc angle CE = 120 + 60 + 60 =
= 240°
h.
the angle AOE = the arc angle AE = the remainder of 360 minus the arc angle ABE of g.
so, angle AOE = 360 - 240 = 120°
Is the opposite of any number smaller than the original number?
Sometimes it is true and sometimes no.
in the case of 3 the opposite is -3
so yes
in the case of -3 the opposite is 3
so no.
If the problem were "The opposites are always less than the original number."
Then the answer would be "No, not true."
Step-by-step explanation:
Answer:
Opposite of a number can be sometimes greater than itself,may be less then it or even equal.

A 400 meters running track has two straight sections, each of length 120 meters and two semicircular ends. calculate the total length of the of the curved sections of the track.
Answer:
160 m
Step-by-step explanation:
Length of running track = Total Length of straight sections + Total length of curved sections
Solving :
⇒ 400 m = 2 x 120 m + Total Length of curved sections
⇒ Total Length of curved sections = 400 m - 240 m
⇒ Total Length of curved sections = 160 m
In how many ways can we stack 10 books?
The arrangement of items can be done with the use of permutation. The stacking of the number of books in the question can be done in 3,628,800 ways.
The arrangement of a given number of items can be done when definite numbers are to be considered at once by the use of permutation. A permutation is a mathematical method that can be used to determine the number of ways by which given items are to be arranged in a particular order.
Given that 10 books are to be stacked, the number of ways (n) that this can be done can be determined by:
n = 10!
= 10 x 9 x 8 x7 x6 x5 x4 x3 x2x 1
n = 3,628,800
Therefore, the 10 books can be stacked in 3,628,800 ways.

What is the probability that she picks a blue marble three times in a row?
According to the question
Samantha has a bag of 5 different colored marbles.
She randomly picks a marble from the bag, records the color, and returns it to the bag before picking another marble.
The probability of picking a bag one time is,
Number of bag pack at a time
Total number of bag
=1/5
The probability of picking a bag second time is,
Number of bag pack at a time Total number of bag
=1/5
The probability of picking a bag third time is,
Number of bag pack at a time
Total number of bag
=1/5
031%
Therefore,
The probability that she picks a blue marble three times in a row is,
= 1/5 X 1/5 X 1/5
1 /125
Hence, the probability that she picks a blue marble three times in a row is 1/125.

The perimeter of a figure refers to the sum of the side lengths of its edges.
Figure (a) : Triangle
⇒ P = 2a + 1 + 3a + a - 4
⇒ P = 6a - 3
⇒ P = 3 (2a - 1)
Figure (b) : Hexagon
⇒ P = 3m - 1 + 3n + n + m + 3m + 1 + 4n + m + n + 2
⇒ P = 3m + m + 3m + m + 3n + n + 4n + n + 1 - 1 + 2

A bookshelf contains 9 mysteries, 7 biographies, and 4 science fiction books. If a book is selected at random. What is the probability of selecting a biography or a mystery?
The probability of selecting a biography or a mystery is 0.8
How to get the probability?
We assume that all the books have the same probability of being randomly selected.
The probability of getting a particular type of book is given by the quotient between the number of these books and the total number of books.
Here we want to find the probability of selecting a biography or a mystery, there are 9 mysteries and 7 biographies, and a total of 20 books in the shelf, so the probability is:
P = (7 + 9)/20 = 16/20 = 4/5 =0.8
The probability is 0.8

Explanation:
There are 8 pizza slices shaded out of 12 total.
One fraction we can form is 8/12
Divide each part by the GCF 4
8/4 = 212/4 = 3This means 8/12 is the same as 2/3
Check out the image below to see how 8/12 and 2/3 are the same. Refer to figure 1. We have 2 slices shaded out of 3 total.
Then check out figure 2 to see how 2/3 and 4/6 are the same. By extension, this means that 8/12 and 4/6 are the same. Figure 2 shows 4 shaded slices out of 6 total.
There are infinitely many ways we can split up this pie, so there are infinitely many fractions to write as the answers.

What is an expression?Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, expansion and division.
The account balance total can be calculated with the following equation where the variable T represents the final balance while the variable C represents her current balance before the three months.
T = C - (9.95 * 3)
The monthly charge is multiplied by the three months that Megan will be charged and then discounted from her current balance in order to give the new Total Balance after paying the subscription for the three months.

Find the next two terms in this
sequence.
20, 32, 42, 50, 56, [?
Answer:
so the next 2 sequences would be 60 and 62
Step-by-step explanation:
The next two terms in the given arithmetic sequence are 60 and 62.
The arithmetic sequence is given as follows:
20, 32, 42, 50, 56, ?
To find the next two terms in the sequence, let's analyze the pattern:
The sequence increases by the following increments:
12, 10, 8, 6
We can observe that the increments are decreasing by 2 each time.
To find the next two terms, we can continue this pattern:
Increment: 4 (6 - 2)
Increment: 2 (4 - 2)
Adding the increments to the previous terms:
56 + 4 = 60
60 + 2 = 62
Therefore, the next two terms in the arithmetic sequence are 60 and 62.

Jill bought 3 pints of strawberries for $3.98 each. What is the best estimate of how much Jill spent?
$4.00
$9.00
$12.00
$8.00
Answer:
Answer C. $12.00
Step One: Round
First you will want to round $3.98 to the nearst hundredth. A little saying my teacher taught me to help you to remember to round:
Find your place, and move next door.
Five or over add one more!
Numbers to the left, stay the same.
Numbers to the right, zeros your name!
So, we choose the 8 in 3.98. We then round. Since the nine is over five, we add one more to it. Causing it to be 4.00
Step Two: Multiply
Now multiply buy 3 since Jill is getting three pints of strawberries
3 times 4 is twelve
So, your answer is 12.00
