Answer and Step-by-step explanation:
The acceptable lengths for the model airplane can be determined by adding and subtracting the maximum allowable variation from the ideal length.
The ideal length of the model airplane is given as 90 cm, and the actual length may vary by at most 0.05 cm.
To find the acceptable lengths, we can use the following calculation:
- Acceptable maximum length: Ideal length + Maximum allowable variation
= 90 cm + 0.05 cm
= 90.05 cm
- Acceptable minimum length: Ideal length - Maximum allowable variation
= 90 cm - 0.05 cm
= 89.95 cm
Therefore, the acceptable lengths for the model airplane range from 89.95 cm to 90.05 cm.
