Question

deeper if items plugged into a circuit use more than 2400 watts of electricity, the circuit overloads. a portable heater that uses 1050 watts of electricity is plugged into the circuit.
a. find the additional numbers of watts you can plug in without overloading the circuit.
the additional numbers of watts you can plug in without overloading the circuit is 1350 ×.
b. in addition to the portable heater, which two of the following items in the table can you plug in at the same time without overloading the circuit?

Explanation:

Step1: List all possible pairs

List all pairs of items from the table (Refrigerator - 200, Microwave - 1200, Television - 150, Computer - 1100).

Step2: Calculate sum for each pair

• Refrigerator + Microwave: \(200 + 1200=1400\)
• Refrigerator + Television: \(200+150 = 350\)
• Refrigerator + Computer: \(200 + 1100=1300\)
• Microwave + Television: \(1200+150 = 1350\)
• Microwave + Computer: \(1200+1100 = 2300\)
• Television + Computer: \(150+1100=1250\)

Step3: Check against 2400 - 1050 = 1350 limit

Since the portable heater uses 1050 watts, the remaining power for other items is \(2400 - 1050=1350\) watts.

• Refrigerator + Television: \(350<1350\)
• Refrigerator + Computer: \(1300<1350\)
• Television + Computer: \(1250<1350\)

Answer:

Refrigerator and Television; Refrigerator and Computer; Television and Computer.
