Answer
(a) $40.6^{\circ}$C
(b) $11.3^{\circ}$F
(c) $11000^{\circ}$F
Work Step by Step
The temperature in Fahrenheit is related to Celcius by the formula $F=\frac{9}{5}C+32$ or $C=(F-32)\frac{5}{9}$
(a) C=$(F-32)\frac{5}{9}=(105-32)\frac{5}{9}=40.6^{\circ}C$
(b) F=$\frac{9}{5}C+32=(\frac{9}{5}\times-11.5)+32=11.3^{\circ}F$
(c) F=$\frac{9}{5}C+32=(\frac{9}{5}\times6300)+32=11000^{\circ}F$
