If $$\sqrt{y} \div \sqrt{121} = 0.03$$​, then find the value of y , giving your answer correct to 3 decimal places.

Correct option is B

Given: ​

​$$\sqrt{y} \div \sqrt{121} = 0.03$$ 

Solution: 

​$$\sqrt{y} \div \sqrt{121} = 0.03 \\ \ \\ \sqrt{y} = 0.03 \times 11 \\ \ \\ \sqrt{y} = 0.33 \\ \ \\ y = (0.33)^2 \\ \ \\ y = 0.1089 \approx 0.109$$​​
