What is the length of the stub-up required IS 3.25 inches.The correct option is b. 3.25 inches.
Step-by-step explanation:
The length of the stub-up required is calculated based on rounding to the nearest eighth inch. In this case, the most accurate answer is 3.25 inches, as it falls between 3.125 and 3.375. To arrive at this conclusion, consider the given options: a. 3.125 inches, b. 3.25 inches, c. 3.375 inches, and d. 3.5 inches. The value that best approximates the desired length while adhering to the rounding criteria is 3.25 inches, making option b the correct answer.
Now, let's delve into the explanation. When rounding to the nearest eighth inch, you must look at the value following the decimal point in the given options. In this case, we're rounding to the nearest eighth inch, so we consider the thousandth place. The value 0.125 falls between 0.125 and 0.375. Since it's equidistant, we choose the option with the nearest quarter-inch value, which is 3.25 inches. This is the optimal choice for maintaining precision and consistency in measurements.
Therefore, when dealing with stub-up lengths and adhering to rounding conventions, 3.25 inches is the accurate and appropriate answer.
The correct option is b. 3.25 inches.
