Answer:
.
Step-by-step explanation:
Given : sequence which has a first term of 14 and has a common ratio of 1.03.
To find :Find the 12th term of the sequence .
Solution : We have given first term of 14 and has a common ratio of 1.03.
Sum of n terms ( .
Where, a = first term , r = common ratio and n = number of terms .
Then, Plug the values a = 14 , r = 1.03 , n = 12.

Answer:
Ratio of blue fish in the small tank to the red fish in large tank is 10 : 6279
Step-by-step explanation:
Let the number of red fish and blue fish in the large tank are x and y respectively.
Similarly ratio of red fish and blue fish in the small tank are x' and y' respectively.
Since in each tank ratio of the red fish to blue fish is 333 : 444
That means x : y = 333 : 444
Or
⇒
⇒ y = --------(1)
Similarly x' : y' = 333 : 444
⇒
⇒
⇒ x' = ------(2)
Ratio of the fish in large tank to the fish in small tank is 464646 : 555
So (x + y) : (x' + y') = 464646 : 555
Now we replace the values of x and y' from equation (1) and equation (2)
Therefore, ratio of blue fish in the small tank to the red fish in large tank is 10 : 6279
