Percentages are used to show the fraction of a thing. For example, if 5 students out of 20 like math, the percentage is 5/20 x 100= 25%
<h3>What is a Percentage?</h3>
This refers to the number of ratios that is described as a fraction of 100 and is denoted by the sign %.
Hence, we can see that although your question is incomplete, I gave you a general overview of percentages for a better understanding of the concept.

Answer:
D
Step-by-step explanation:
4 out of 5 games is 80%:
So if we know, as a rule that "Joel scores in 80% of his games.", the probability that he will score in 80% of his games is 1 - that is, we know it for sure
100% sure
Answer:
$16,640
Step-by-step explanation:
Tim's total annual wage expense is ...
($8.00 /h)(40 h/wk)(52 wk/yr) = $8×40×52 /yr = $16,640 per year
Answers:
- Total amount of money = 220 dollars
- Amount Farah gets = 100 dollars
==========================================================
Explanation:
- F = amount Farah gets
- S = amount Shaiyara gets
- Z = amount Zahin gets
The money is divided in the ratio 10:7:5
This means that
for some positive real number x.
Since Shaiyara gets $20 more than Zahin, we can say,
S = Z+20
Let's plug in S = 7x and Z = 5x and solve for x
S = Z+20
7x = 5x+20
7x-5x = 20
2x = 20
x = 20/2
x = 10
Therefore,
- F = 10x = 10*10 = 100
- S = 7x = 7*10 = 70
- Z = 5x = 5*10 = 50
The ratio F:S:Z becomes 100:70:50 which reduces fully to 10:7:5 after dividing all three parts by the GCF 10.
The total sum of money shared is 100+70+50 = 220 dollars and Farah gets $100 of that total.
Answer:
1) A 2) B 3) C 4) C 5) A 6) B
Step-by-step explanation:
1) Slope is calculated by the change in y over the change in x thus (5-3)/(2-(-1)) = 2/3
2) Since there is no change in y, there is no slope.
3) The change in x is given which is 10-2 so the change in y is y2-3. For the slope to be 3/4 y must equal 6. Therefore y2 is 9.
4) Cosine is adjacent over hypotenuse and Tangent is opposite over adjacent. Given 3/5 as A/H you can construct a right triangle with the adjacent as 3 and hypotenuse as 5. The Pythagorean theorem says the adjacent squared plus the opposite squared is equal to the hypotenuse squared.
3^2 + O^2 = 5^2
O=4
Therefore TanP is 4/3
5) Pythagorean theorem again. 
Therefore your hypotenuse is equal to 
6) Csc is the inverse of the Sin function. So it becomes 5/4.
