Question

a manufacturer of nickel-cadmium batteries recommends storing the batteries at temperatures ranging from -20C to 45C. use an inequality to describe the temperatures (in degrees Fahrenheit) at which the batteries can be stored

Answer 1

The inequality is:

`-20\leqslant x\leqslant45`

Explanation:

Let x be the temperature at which the batteries will be stored. We know that this temperature has to be greater than or equal to -20 and less than or equal to 45.

Therefore, the inequality that would describe this situation is:

`-20\leq x\leq45`
