Starting from 15°C, what was the starting temperature of the water in Fahrenheit?

Explanation:
To convert a temperature from Celsius to Fahrenheit, you can use the formula: \[ F = \left( C \times \frac{9}{5} \right) + 32 \] In this scenario, the starting temperature is 15°C. Plugging this value into the formula gives: \[ F = \left( 15 \times \frac{9}{5} \right) + 32 \] Calculating this step-by-step: 1. Multiply 15 by 9/5: \[ 15 \times 1.8 = 27 \] 2. Add 32 to the result: \[ 27 + 32 = 59 \] Thus, the starting temperature of the water in Fahrenheit is 59°F. The answer A is correct because it accurately reflects the conversion of 15°C to Fahrenheit using the established formula.

To convert a temperature from Celsius to Fahrenheit, you can use the formula:

[ F = \left( C \times \frac{9}{5} \right) + 32 ]

In this scenario, the starting temperature is 15°C. Plugging this value into the formula gives:

[ F = \left( 15 \times \frac{9}{5} \right) + 32 ]

Calculating this step-by-step:

  1. Multiply 15 by 9/5:

[ 15 \times 1.8 = 27 ]

  1. Add 32 to the result:

[ 27 + 32 = 59 ]

Thus, the starting temperature of the water in Fahrenheit is 59°F. The answer A is correct because it accurately reflects the conversion of 15°C to Fahrenheit using the established formula.
