Answer:
Step-by-step explanation:
The formula for cos θ is a/r. A is the first number (10) and b is the second number (6). R is the hypoteneuse which can be found through r = .
In the equation you'd write that as r = which can be simplified to .
You end up with and you simplify this by doing , ending with the result of .
(I also got this answer right on the test.)
So you are given that 45 people in the age range of 18 to 29 who voted make up 10% of the total voters.
And you also know that 30% of the voters are in the age range of 30-49. And you need to find out how many people aged 30-49 voted.
So 10% of the total make up 45 people.
That means for 30% of the total number people, there would be 45 x 3 people, or 135 people. Because 10% x 3 = 30%
So, great job! :D
