Because a percent is a fraction of 1/100 of a whole thing. for example a whole is 200 and we want to find the 37% of it, we would divide 200 over 100 (which is the percent of the whole thing) and the multiply it by 37 (that is the percentage of the part of the whole thing) and we get 74.
74=37% of 200
Answer:
The equation: 2<em>n</em> - 3 ≤ -21
The answer to the equation: <em>n</em> ≤ 9
Step-by-step explanation:
How to get the equation:
<u>The difference of</u> symbolizes subtraction. Because we are subtracting twice a number and 3, the first part of the equation can be written as 2<em>n</em> - 3. The <em>n</em> symbolizes the number.
<u>is at most</u> symbolizes a less than or equal to sign. That sign is ≤. And what is it less than or equal to? -21.
Now are equation is 2<em>n</em> - 3 ≤ -21
How to solve it:
2<em>n</em> - 3 ≤ -21
Add 3 to both sides of the equation
2<em>n</em> ≤ 18
Divide both sides of the equation by 2
<em>n</em> ≤ 9
Answer:
Step-by-step explanation:
First Add the scores.
Score Total = 787 + 615 + 550 + 674 + 784+ 773 + 620 + 720 + 704
Score Total = 6227
Now divide by the number of members of the sum.
Number of members = 9
The average score = Total Score / number of members
The average score = 6227 / 9 = 691.9
The average score = 692 which is C
Hm let's see the answer should be by the definition of isosceles triangle
