Question

the amount of electricity used in a typical all - electric home is shown in the circle graph below. if, in a certain month, a home used 1,500 kwh (kilowatt - hours), find the amount of electricity used from the graph.
the amount of electricity used by the water heater
kwh

Explanation:

Step1: Identify Water Heater's Percentage

From the circle graph, the water heater uses 11% of the total electricity.

Step2: Calculate Electricity for Water Heater

Total electricity used is 1,200 kWh. To find 11% of 1,200, use the formula: $ \text{Amount} = \text{Total} \times \frac{\text{Percentage}}{100} $
Substitute values: $ 1200 \times \frac{11}{100} = 1200 \times 0.11 = 132 $

Answer:

132
