Question

If the temperature outside is 30°C, what is the temperature in °F? A. 97.2 B. 22 C. 54 D. 86

Answer 1

`\large\boxed{30^oC=86^oF}\to D.`

Explanation:

`\text{Celsius to Fahrenheit formula:}`

`T_((^oF))=(9)/(5)\cdot T_((^oF))+32`

`T_((^oF))=30\!\!\!\!\diagup^6\cdot(9)/(5\!\!\!\!\diagup_1)+32=(6)(9)+32=54+32=86`

Answer 2

D. 86

Explanation:

The equation for converting Celsius to Fahrenheit: A = (degrees Celsius) x 1.8 + 32

Therefore,

A = 30 x 1.8 + 32

A = 54 + 32

A = 86
