Question

1. convert 86°f to celsius: mark only one oval 25°c 35°c 30°c 40°c 13 what is 32°f in celsius? mark only one oval 64°c 32°c 0°c -32°c 14. convert 100°c to fahrenheit: * mark only one oval. 200°f 232°f 180°f 212°f

Explanation:

Step1: Recall the conversion formula

The formula to convert Fahrenheit (\(F\)) to Celsius (\(C\)) is \(C=\frac{5}{9}(F - 32)\).

Step2: Substitute \(F = 86\) into the formula for question 12

\(C=\frac{5}{9}(86 - 32)=\frac{5}{9}\times54 = 30\).

Step3: Substitute \(F = 32\) into the formula for question 13

\(C=\frac{5}{9}(32 - 32)=\frac{5}{9}\times0 = 0\).

Step4: Recall the formula to convert Celsius to Fahrenheit

The formula is \(F=\frac{9}{5}C+32\).

Step5: Substitute \(C = 100\) into the formula for question 14

\(F=\frac{9}{5}\times100+32=180 + 32=212\).

Answer:

1. \(30^{\circ}C\)
2. \(0^{\circ}C\)
3. \(212^{\circ}F\)
