convert 89°f to °c round to the nearest whole number
answer

Explanation:

Step1: Kelvin to Celsius formula

$T(^\circ\text{C}) = T(\text{K}) - 273.15$

Step2: Calculate 110 K to °C

$110 - 273.15 = -163.15 \approx -163.2$

Step3: Fahrenheit to Celsius formula

$T(^\circ\text{C}) = \frac{5}{9} \times (T(^\circ\text{F}) - 32)$

Step4: Calculate 45°F to °C

$\frac{5}{9} \times (45 - 32) = \frac{5}{9} \times 13 \approx 7.2$

Step5: Calculate 89°F to °C

$\frac{5}{9} \times (89 - 32) = \frac{5}{9} \times 57 \approx 31.67 \approx 32$

Answer:

-163.2 °C
-7.2 °C
32 °C
