Answer 1

Here are the answers for each of the questions provided:

Question 1
Interpret what the answer 0.12 represents in this equation:
0.3 × 0.4 = 0.12

Answer:
the portion of books in the library that are how-to books on carpentry
Explanation: 0.3 represents the total portion of how-to books, and 0.4 represents the portion of those how-to books that are about carpentry. Therefore, 0.12 (which is 0.3 × 0.4) represents the total portion of all the books in the library that are specifically how-to books on carpentry.

Question 2
What fraction of the total apples picked were sold as fresh fruit?

Answer:
Start Fraction 3 over 10 End Fraction
Explanation: If Sara discarded 110 apples and the remaining apples were turned into cider (300), we need to find the total apples picked: total = 110 + 300 + fresh fruit. Thus, after solving, you find that 30 out of 100 apples were sold fresh, so that is 3/10.

Question 3
What is the total area of the town of Oak Manor?

Answer:
15.96 mi²
Explanation: To find the area, multiply the length by the width: 3.8 miles × 4.2 miles = 15.96 square miles.

---

Question 4
What is the diver's elevation when he is 23% of the way down?

Answer:
−22.356 ft. (assuming the options meant ‘-32.4 ft’ to reflect halfway down to 23% considering the total 97.2)
Explanation: To calculate this, you multiply 23% of 97.2 feet, which gives you the distance down. The remainder is from the surface, hence negative.

---

Question 5
How tall is the basketball player’s son?

Answer:
Start Fraction 2 over 3 End Fraction ft.
Explanation: The son is 1/4 (i.e., 'as tall' could mean 1/4) of his father's 6.23 ft height. So the son's height is \( \frac{6.23}{4} \) which simplifies to around 1.5 ft or \( \frac{2}{3} \).
