Convert 40 degrees Celsius to degrees Fahrenheit using F = 1.8 x C + 32.
Answer and explanation
Correct answer: D. 104 degrees F
- Step 1: 1.8 x 40 = 72. Step 2. 72 + 32 = 104. Answer: 104 degrees F. Why not the others: 72 degrees F: the constant 32 was left out. 4.4 degrees F: the formula for the opposite conversion was used. 124.8 degrees F: this value comes from a slip in the arithmetic.
