Question

The label on the car's antifreeze container claims to protect the car between -30°C and 130°C. To convert Celsius temperature to Fahrenheit temperature, the formula is C+32. Write and solve the inequality to determine the Fahrenheit temperature range at which this antifreeze protects the car.

a) C+32<130
b) −223c) −30d) Both a and b.

Answer 1

The Fahrenheit temperature range at which this antifreeze protects the car is from -50.4°F to 291.6°F.

Step-by-step explanation:

To convert Celsius temperature to Fahrenheit temperature, we can use the formula F = (C + 32) × 1.8. We are given that the antifreeze protects the car between -30°C and 130°C. So, let's substitute the given values into the formula:

For the lower limit, we have F = (-30 + 32) × 1.8 = -28 × 1.8 = -50.4°F

For the upper limit, we have F = (130 + 32) × 1.8 = 162 × 1.8 = 291.6°F

Therefore, the Fahrenheit temperature range at which this antifreeze protects the car is from -50.4°F to 291.6°F.
