Carlos found that the length of the diagonal of his laptop monitor is [tex]\sqrt{290}[/tex]. If the manufacturer rounds to the nearest whole inch, what size is the monitor as measured by the diagonal?

A. 12
B. 17
C. 97
D. 245

Answer :

First, we note that the diagonal of the laptop monitor is given by

[tex]$$
\sqrt{290}.
$$[/tex]

Calculating this expression gives a value of approximately

[tex]$$
\sqrt{290} \approx 17.03.
$$[/tex]

Since the manufacturer rounds to the nearest whole inch, we round [tex]$17.03$[/tex] to the nearest whole number, which is [tex]$17$[/tex].

Thus, the size of the monitor, as measured by the diagonal, is [tex]$\boxed{17}$[/tex] inches.
