okay, i've answered can you tell me the answers to check?
Of course! Here are the answers:
1. A rational number can be expressed as a fraction, while an irrational number cannot be expressed as a fraction and has non-repeating, non-terminating decimal representation.
2. The area of a triangle is calculated as 1/2 * base * height.
3. The formula for finding the volume of a rectangular prism is length * width * height.
4. To convert a fraction to a decimal, divide the numerator by the denominator.
5. To solve a two-step equation, perform the inverse operation (e.g., addition and then multiplication or subtraction and then division) to isolate the variable.
6. The slope of a line can be found using the formula: slope = (y2 - y1) / (x2 - x1), given two points (x1, y1) and (x2, y2) on the line.
7. The probability of an event happening is calculated as the number of favorable outcomes divided by the total number of possible outcomes.
8. The domain of a function is the set of all possible input values, while the range is the set of all possible output values.
9. To simplify and factor algebraic expressions, look for common factors and apply algebraic operations such as distribution and factoring.
10. The circumference of a circle is calculated as 2πr, where r is the radius of the circle.
