Answer: 25%
Step-by-step explanation: The question tells us that the population decreases by 1/4 every single year. That means, since 1/4 equals .25, the population decreases by 25% every year :)
Step-by-step explanation:
To find a set of 3 leg lengths that will form a right-angled triangle, the square of the largest leg must be equal to the sum of the squares of the other 2 legs.
We try out all the options:
39² = 1521, 15² + 36² = 1521.
12² = 144, 8² + 4² = 80.
17² = 289, 13² + 9² = 250.
Since 39² equals 15² + 36², option A is the correct answer.

Answer: $12 an hour
Step-by-step explanation:
Rosey works 37 hours a week and 4 weeks in a month.
Total hours are:
= 37 * 4
= 148 hours
In order to at least cover the $1,776 in expenses she incurs every month, Rosey's hourly pay must be:
= expenses / working hours in month
= 1,776 / 148
= $12 an hour
Answer:
1) The value of c is given by
2) The value of k is given by
Step-by-step explanation:
Given that function g is defined by 
, where c is a constant.
To find c:
Also given that value of g(x) at x=0.5 is equal to -1
ie., 
At x=0.5
Therefore
2) Given that function h is defined by 
, where k is a constant.
To find k:
Also given that value of h(x) at x=20 is equal to 65
ie., 
At x=20
Therefore
