Answer:
9 years.
Step-by-step explanation:
For 50 raccoons the equation is
0.4x^2+2x+2 = 50
0.4x^2+2x - 48 = 0
x = [-2 +/- sqrt(2^2- 4* 0.4*(-48)] / (2*0.4)
= (-2 +/- sqrt 9) / 0.8
= 8.74 , - 13.75 (ignore the negative).
So it's 9 years.

Answer:
.4 hours or 24 minutes
Step-by-step explanation:
We can use proprtions to solve this problem. Put distance over time
65 miles 26 miles
------------- = -----------
1 hour x hours
Using cross products
65x = 26
Divide by 65
65x/65 = 26/65
x = .4 hours
or we can change to minutes
.4 hours * 60 minutes/ 1 hour = 24 minutes
