Jeannie knows that if she multiplies the current of the circuit by its resistance, she can find the voltage. The circuit right now has a resistance of 4i ohms and a current of 12-7i amps. What is the voltage of the circuit?

In a coastal town, the humidity, measured in grams of water per kilogram of air, increases by 43% for every 1 degree celsius increase in temperature. a scientist observes that the humidity on monday morning is 5.75 grams per kilogram. he wants to know how much the temperature must increase for the humidity to reach at least 49.17 grams per kilogram. let t represent the increase in temperature, in degrees celsius, from monday morning's observation. write an inequality to represent the situation, and use it to determine the desired temperature increase.
