Answer:
20.5 years
Step-by-step explanation:
The population is given by the exponential function ...
p = 16000·(1 +0.022)^t
When p = 25000, we can find the value of t by taking logarithms.
log(25000/16000) = t·log(1.022) . . . . . divide by 16000, take the log
t = log(25/16)/log(1.022) ≈ 20.5 . . . . . . divide by the coefficient of t
It will take about 20.5 years for the population to reach 25000.

Answer:
Step-by-step explanation:
The answer is 96 because you have to 12 x 8 so it can be 96
Answer:
use x to represent the unkown numbers
and y to represent the one number which is more than 11
so the equation will be like this
x+x+y=87
x+x+11=87
2x+11=87
2x=87-11
2x=76
now divide both sides by the x variable
2x/2=76/2
x=38
now you know one x to be 38
and the question made it clear that one number is eleven times more than the other
therefore the other number is 49
so 38+49=87
