The recommended ratio of gallons of water per fully grown goldfish in a tank is 12:1. This means for every goldfish that grows up to 12 inches, there should be 12 gallons of water in the tank.
James is setting up a fish tank and planning to house a breed of goldfish that typically grows to be 12 inches long. Considering the recommendation, there should be 1 gallon of water for every inch of fish length in the tank. Therefore, for a fully grown goldfish of 12 inches, James will require 12 gallons of water per goldfish - this is the recommended ratio of gallons of water per fully grown goldfish in the tank.

The length of PQ is 19.66 units
Step-by-step explanation:
The given is:
1. PK = KQ = 12
2. m∠P = 35º
We need to find the length pf PQ
∵ PK = KQ
∴ m∠P = m∠Q
∵ m∠P = 35°
∴ m∠Q = 35°
The sum of measures of the angles of a triangle is 180°
∴ m∠P + m∠Q + m∠K = 180°
∴ 35 + 35 + m∠K = 180
∴ 70 + m∠K = 180
- Subtract 70 from both sides
∴ m∠K = 110°
Let us use cosine rule to find the length of PQ
∵ PQ =
∵ PK = 12 , KQ = 12 , m∠K = 110°
- Substitute these values in the rule
∴ PQ =
∴ PQ = 19.66
The length of PQ is 19.66 units
