Answer:
I believe it is the vertex, of an angle.
Step-by-step explanation:
It is the vertex, because that is what you would call the bottom point of an angle.
An angle is a figure created by two rays, known as the angles' sides, that share a common terminus, known as the angle's vertex. A point lies in the interior of an angle if it lies between the rays that form the angle.
What is an angle?An angle is a figure created by two rays, known as the angles' sides, that share a common terminus, known as the angle's vertex. Angles created by two rays are located in the plane containing the rays. Angles are also generated when two planes intersect. These are known as dihedral angles.
An angle has two rays and the area that lies between the two rays is known as the interior of the angle, while the area that is not between the two rays is the exterior of the angle.
Therefore, A point lies in the interior of an angle if it lies between the rays that form the angle.

Answer: (a) 8(x + a) --> 8x + 8a

Step-by-step explanation:
f(x) = 8x²
f(a) = 8a²

A collection of 77 quarters and dimes is worth $12.50. How many quarters are in the collection? PLS HELP ILL GIVE YOU BRAINLEST ANSWER
Answers
Answer:
32
Step-by-step explanation:
77 quarters and dimes
q + d = 77
subtract q from both sides
d = 77 - q
---------------------------
A collection of quarters and dimes is worth $12.50 (1250 cents)
25q + 10d = 1250
substitute for d
25q + 10(77 - q) = 1250
distribute
25q + 770 - 10q = 1250
Combine like terms
15q + 770 = 1250
subtract 770 from both sides
15q = 480
divide both sides by 15
q = 32

Answers
There are no possible combination of arrows for a score of exact 100.
What is the meaning of a sequence of numbers?In a sequence of numbers there are many numbers having a kind of relation between them. On the basis of this relation a sequence can be categorised as arithmetic, geometric or harmonic sequence.
Given that,
The scores achieved by Juanita by each arrow are 16, 17, 23, 26, 29 or 40.
In order to find the minimum number of arrows for the total score of 100, find three larger scores adding up to 100 as follows,
The largest score is 40.
The remaining 60 can be found by adding the combinations of remaining numbers as,
16 + 17 = 33,
29 + 13 + 17 = 59
26 + 17 + 29 = 72
And so on.
Thus, it is clear from the given numbers that no possible combination can give a sum of exact 100.
Hence, Juanita has no combination of arrows for getting a score of exact 100.

Answers
Answer:
From your selections of answers, It's B: 12 x^3 - 21 b^5, but it's not completely simplified.
Step-by-step explanation:
Simplify the following:
3 (3 x^3 - 7 b^5) + 3 x^3
3 (3 x^3 - 7 b^5) = 9 x^3 - 21 b^5:
3 x^3 + (9 x^3 - 21 b^5)
Grouping like terms, 9 x^3 + 3 x^3 - 21 b^5 = (3 x^3 + 9 x^3) - 21 b^5:
(3 x^3 + 9 x^3) - 21 b^5
3 x^3 + 9 x^3 = 12 x^3:
12 x^3 - 21 b^5
Factor 3 out of 12 x^3 - 21 b^5:
Answer: (3 (4 x^3 - 7 b^5)) = 12 x^3 - 21 b^5
A box contains 54 coins which are either 20-cent coins or 50-cent coins. If the total value of all the coins is $20.70, find the number of 20-cent coins in the box. LOF 1 11.
Answers
Number of 20-cent coins in the box are 33.
1. Let's assume the number of 20-cent coins to be x and the number of 50-cent coins to be y.
2. We can set up two equations based on the given information:
- x + y = 54 (since the total number of coins in the box is 54)
- 0.20x + 0.50y = 20.70 (since the total value of all the coins is $20.70)
3. We can multiply the second equation by 100 to get rid of the decimals:
- 20x + 50y = 2070
4. Now, we can use the first equation to express y in terms of x:
- y = 54 - x
5. Substitute the value of y in the second equation:
- 20x + 50(54 - x) = 2070
6. Simplify and solve for x:
- 20x + 2700 - 50x = 2070
- -30x = -630
- x = 21
7. Substituting the value of x back into the first equation:
- 21 + y = 54
- y = 33
8. Therefore, there are 21 20-cent coins and 33 50-cent coins in the box.

A country with a population of 2.1 million experiences 4310 fatalities as a result of a virus. What is the fatality rate per 100,000?
Answers
The fatality rate per 100,000 is 205.23.
In mathematics, a rate of something is simply the ratio between two related quantities which are expressed different units. While expressing the units of any rate, the word "per" is used to distinguish the units of the two measurements used to calculate the rate.
Here, we are given that a country has a population of 2.1 million.
2.1 million can be written as- 2,100,000
The number of fatalities experienced by the country = 4,310
This means that there where 4,310 fatalities per 2.1 million of the population.
The number of fatalities per 100,000 will be given as-
4,310/ 2,100,000 × 100,000
expanding it further we get-
4,310/ 21

A train running between two stations 50 Km apart arrives on time if it travels at an
average speed of 60 km/h. How late will it be if travels at an average speed of 50 Km/h?
Answers
If the train travels at an average speed of 50 Km/h, it would be late by 10 minutes.
How late will the train be if it travels at an average speed of 50 Km/h?Speed is simply referred to as distance traveled per unit time.
It is expressed as:
Speed = distance / time
Given that the train running between two stations 50 Km apart arrives on time if it travels at an average speed of 60 km/h.
The time taken by the train to travel 50 km at an average speed of 60 km/h can be calculated using the formula:
Speed = distance / time
time = distance / speed
time = 50 km / 60 km/h
time = 5/6 hour
Next, if the train travels at an average speed of 50 km/h, the time taken to cover the same distance of 50 km would be:
Speed = distance / time
time = distance / speed
time = 50 km / 50 km/h
time = 1 hour
Now, the difference in time between the two scenarios would be:
time difference = 1 hour - 5/6 hour
time = 1/6 hour
Convert to minutes
time = 1/6 × 60
time = 10 minutes
Therefore, the train would be late by 10 minutes.
