Answered by GPT-4o mini
Certainly! Here are the answers and explanations for each of the questions:

1. **Rational Numbers are...**
- **numbers that can be written as a fraction** (True)
- **numbers that have repeating decimals** (True)
- **numbers that have decimals that never end and do not repeat** (False - this describes irrational numbers)
- **numbers that cannot be negative** (False - rational numbers can be negative)
- **numbers that have a decimal that does not continue on forever** (True - this applies to rational numbers)

2. **Irrational Numbers are...**
- **numbers that have decimals that do not repeat** (True)
- **numbers that have decimals that do not stop** (True)
- **numbers that can be written as a fraction** (False - this describes rational numbers)
- **numbers that can only be negative** (False - irrational numbers can be both positive and negative)

3. **Choose all that are irrational numbers:**
- **4.567647...** (This number has a non-repeating and non-terminating decimal, therefore it is an irrational number)

4. **What is √2 as a decimal?**
- The decimal is approximately **1.414** (often rounded to a few significant figures). If "none of these" is an option, it would depend on the provided choices.

5. **Convert 0.75 to a fraction:**
- 0.75 can be converted to the fraction **3/4**.

6. **Given a square with an area of 64, what is the length of each side?**
- The length of each side is **8** (because √64 = 8).

7. **In the expression √x the symbol over the x is called a:**
- **radical** (The entire symbol √ is called a radical, while x is the radicand.)

8. **Choose all that apply below: 5 is equivalent to...**
- Since options aren’t provided, generally, 5 can be equivalent to 5/1, or 5.0, etc. It depends on the options.

9. **An example of a perfect square number is:**
- **9** (because it is 3²).

10. **An example of a perfect cubic number is:**
- **27** (because it is 3³).

11. **Which are examples of Pythagorean Triples?**
- **3,4,5** (True, since \(3^2 + 4^2 = 5^2\))
- **7,24,25** (True, since \(7^2 + 24^2 = 25^2\))
- **5,12,14** (False, since \(5^2 + 12^2 ≠ 14^2\))
- **20,21,30** (False, since \(20^2 + 21^2 ≠ 30^2\))

12. **Given that the two legs of a right triangle are 8 and 15, what is the length of the hypotenuse?**
- Using the Pythagorean theorem: hypotenuse = √(8² + 15²) = √(64 + 225) = √289 = **17**.

13. **Is the triangle shown below a right triangle?**
- If the sides are **5, 12, and 13**, then:
- **Yes, because 5, 12, 13 is a Pythagorean Triple.**
