the point $sqrt{x}$ is plotted on the number line.\nwhat whole number best approximates the value of $x$?\n81\n87\n88\n93
Answer
Explanation:
Step1: Estimate the value of $\sqrt{x}$
The point $\sqrt{x}$ is between 9.3 and 9.4, so a good estimate for $\sqrt{x}$ is 9.35.
Step2: Calculate the value of $x$
Since $\sqrt{x}\approx9.35$, then $x\approx(9.35)^2$. $(9.35)^2 = 9.35\times9.35=87.4225$.
Answer:
87
