Question

there is an exact formula to convert celsius temperatures to fahrenheit. however, a simple approximation is twice the celsius temperature plus 30. what is the approximate fahrenheit temperature for 20°c? °f

Explanation:

Step1: Identify the Celsius temperature

The Celsius temperature $C = 20$.

Step2: Apply the approximation formula

The approximation formula is $F=2C + 30$. Substitute $C = 20$ into the formula: $F=2\times20+30$.

Step3: Calculate the result

First, calculate $2\times20 = 40$. Then, $40+30=70$.

Answer:

$70$
