The inequality that describes the allowable lengths for the board is |x - 40.50| ≤ 0.25
The given parameters are
Length = 40.50 cm
Tolerance = 0.25 cm
The inequality that describes the allowable lengths for the board is represented as:
|x - Length| ≤ Tolerance
This gives
|x - 40.50| ≤ 0.25
Hence, the inequality that describes the allowable lengths for the board is |x - 40.50| ≤ 0.25
