Provide an appropriate response.Explain how you could find an approximation to  to the nearest tenth without using a calculator. 

What will be an ideal response?


Possible answer. Use trial and error. Look for a number whose square is close to 90. Start by squaring whole numbers to determine that  lies between 9 and 10. Then try numbers between 9 and 10 with one decimal to see which one has a square closest to 90. To the nearest tenth,
