Answer 1

C.

Step-by-step explanation:

Answer 2

The average temperature for Russ' visit to Canada, given as 12 degrees Celsius, equals approximately 54 degrees Fahrenheit, when converted using the formula C = 5/9 (F-32). Thus, option C is the closest.

Step-by-step explanation:

To find the average temperature in degrees Fahrenheit for Russ' visit to Canada, we need to substitute the given average temperature in degrees Celsius into the formula for converting Celsius to Fahrenheit. The conversion formula from degrees Celsius to degrees Fahrenheit is C = 5/9 (F-32).

Let's substitute C = 12 into the formula:

• 12 = 5/9 (F-32)
• To isolate 'F', we first multiply both sides by 9/5: 12*(9/5) = F - 32
• This simplifies to: 21.6 = F - 32
• We then add 32 to both sides: F = 21.6 + 32
• Solving for 'F' gives us 53.6.

So, the average temperature for Russell's visit, in degrees Fahrenheit, is closest to 54 °F, which matches option C on your list.
