Final answer:
30.0°C converted to Fahrenheit is 86.0°F using the conversion formula (T°C × 9/5) + 32.
Step-by-step explanation:
To convert 30.0°C to Fahrenheit, we use the conversion formula:
T°F = (T°C × 9/5) + 32
Let's plug in the value:
T°F = (30.0 × 9/5) + 32
T°F = (54) + 32
T°F = 86°F
So, 30.0°C converted to Fahrenheit is 86.0°F, which corresponds to option b.
