the ideal length of one model airplane 90cm the actual may vary from ideal from at most .05 cm. What are the accepatable lengths for the model airplanes? Use absolute and write and solve an equation

Question

anonymous · Answer

$$\text{Let }L_A = \text{the actual length of a model airplane}$$
$$\text{Let }L_I = \text{the ideal length of a model airplane}$$

then $$|L_A - L_I| \le 0.05\,\text{cm}$$

Thanks so much! and now I just solve for the set right?

anonymous · Answer

you want to find $$L_A$$, right?  Also, you will need to use $$90\,\text{cm} = L_I$$

okay. thanks I really appreciate it!
