About 75 percent of the energy that passes through a fluorescent bulb is used as light. if a fluorescent bulb uses 2,000 kilowatt-hours, how much energy is used as light?

If a fluorescent bulb uses 2,000 kilowatt-hours, then the amount of energy used as light is 1500.

Step-by-step explanation:

The question provides us with all the information we need very simply. It wants to find 75% of 2000. In order to find 75% of 2000, first we must convert 75% into a decimal, which we can do by moving the decimal point two spaces to the right. In this case, 75% as a decimal would be 0.75 Now, all that is left is to multiply 0.75 by 2000. 0.75 x 2000 is 1500.

If a fluorescent bulb uses 2,000 kilowatt-hours, then the amount of energy used as light is 1500.

maximum area = xy = (16)(32) = 512 ft2

to maximize the area of the garden, the side of the fence parallel to the side of the house should be 32 ft long, and the other two sides should both have length 16 ft.'
