Answer:
Explanation:
The square root of 42 is 6.48074069841.
To find the hundredth value, she should round up from 6.48 to 6.5.
Meaning most likely D, estimate that its value is about 6.5, since that is the closest to the square root of 42.
A would not help, it's more than those ones.
B and C would not help due to the infinitely many possible numbers between 6.4 and 6.5, and 6.5 and 6.6.
We can only assume D is correct, since it's the closest to the actual value.
