✅ C. 246.1°C

i got it right⬇

Answer 2

Kurt should set the oven at 246.1°C ⇒ C

Explanation:

The Fahrenheit scale and the Celsius scale are both used to measure temperature

• The formula to convert Fahrenheit to Celsius is °C = (°F - 32) ×
  `(5)/(9)`
• To change from Fahrenheit to Celsius insert the °F temperature measurement in the formula and then solve to find the result

∵ Kurt cookbook tells him to preheat his oven to 475°F

∴ °F = 475°F

∵ The oven is only marked in °C

- Change it by using the formula above

∵ °C = (475 - 32) ×
`(5)/(9)`

∴ °C = 443 ×
`(5)/(9)`

∴ °C = 246.11111

- Round it to the nearest tenth

∴ °C = 246.1°C

Kurt should set the oven at 246.1°C
