If the head of a fish measures 9 inches and the tail's length is equal to the head plus half the body's length, which of the following calculations will determine the length of the entire fish accurately?
- 9 + (9 + (18 + 4.5)) (correct)

Study Notes
Question 11
- The missing numbers in the sequence 19, 20, 21, ?, ?, 26, 28, 32, 33, 40 are 23 and 25.
- The sequence is a combination of two interwoven patterns: a sequence of consecutive numbers (19, 20, 21, 23, 25, 26, 28, 32, 33, 40), and a sequence of prime numbers (19, 23, 29, 31, 37, 41).
Question 12
- The fish's head is 9 inches long.
- The tail is equal to the head plus half the length of the body.
- The body is equal to the length of the head plus the tail.
- To solve this, we can use algebra: let 'x' represent the body's length.
- The tail is equal to 9 + (x/2).
- The body is equal to 9 + (9 + (x/2)).
- Solving for x, we get x = 54 inches.
- The entire fish is 9 inches (head) + 54 inches (body) + 27 inches (tail) = 90 inches long.
