Answer: Approximately 112.86 miles in any direction away from the radio station
Step-by-step explanation: If the radio signal of the radio station can cover a circular area of 40,000 square miles, it simply means any direction away from the radio station that is within the coverage area. With the radio station as the center, we would have a radius that can reach any point within the area, and any distance beyond the radius would be out of coverage area. If the area has been given as 40000, then we have;
Area of a circle = pi x r^2
40000 = 3.14 x r^2
By cross multiplication we now have
40000/3.14 = r^2
Add the square root sign to both sides of the equation
112.8665 = r
Therefore, the farthest a person can live away from the radio station is approximately 112.86 miles
Answer:
12% of male ducks to 42% of female ducks
Step-by-step explanation:
40% of the ducks are male, so 60% are female.
30% of the ducks with side effects are male, so 70% are female
30% of 40% is .3 * .4 = .12 or 12%
70% of 60% is .7 * .6 = .42 of 42%
Answer:
The number of student increased each year by 986.58.
Step-by-step explanation:
Given : In 2002, there were 972 students enrolled at Oakview High School.
To find : The number of students has increased by 1.5% each year ?
Solution :
Using the exponential growth function,
Here, 
is the initial population
r=1.5%=0.015 is the rate
t=1 time
i.e. the number of student increased each year by 986.58.
The answer I believe is 7
D –648, 1944, –5832
throught one, multiply by 9
