To find the best estimate of the number of degrees that the temperature has risen, we can subtract the temperature at 6 a.m. from the temperature at 10 a.m.:
\[
52.14 - 44.65
\]
Calculating this step by step:
1. Subtract the whole number parts: \(52 - 44 = 8\)
2. Subtract the decimal parts: \(0.14 - 0.65 = -0.51\)
Now, we combine these results:
\[
8 - 0.51 = 7.49
\]
Thus, the temperature has risen approximately 7.49 degrees.
The best estimate from the options given is:
**7.49**
