Question

The label on the car's antifreeze container claims to protect the car between −30°C and 130°C. To covert Celsius temperature to Fahrenheit temperature, the formula is C equals five ninths times the quantity F minus thirty two.. Write a compound inequality to determine the Fahrenheit temperature range at which the antifreeze protects the car

Answer 1

Answer:

-22°F < x < 266°F.

Step-by-step explanation:

The question states the incorrect formula to convert the Celsius temperature (C) into the Fahrenheit temperature (F). The correct one is given by:

F = 9C/5 + 32.

The given temperature inequality in Celsius is:

-30°C < x < 130°C; where x is any number that satisfies the inequality.

To convert it into Fahrenheit, simply plug in the values in the above formula.

Lower Limit:

F = 9(-30)/5 + 32.

F = -54 + 32.

F = -22°F.

Upper Limit:

F = 9(130)/5 + 32.

F = 234 + 32.

F = 266°F.

Therefore, the inequality will be -22°F < x < 266°F!!!
