An electric motor makes 3,000 revolutions per minutes. How many degrees does it rotate in one second? We want to convert revolutions per minute to revolutions per second: 3000 revolutions per minute / 60 seconds per minute = 50 revolutions per second Using our [URL='http://www.mathcelebrity.com/anglecon.php?quant=50&type=revolution&pl=Calculate']revolutions to degrees calculator[/URL], we get [B]18,000[/B]

An electrician starts off the day with 600 feet of copper wiring on his truck. During the course of the day he uses pieces 100, 82, 25, and 40 feet long. The next day, he purchases another 400 feet and puts it on his truck and later in the day uses pieces of 41, 39, and 44 feet long. How many feet of wiring are still on the truck at the end of the second day? If the electrician uses pieces, we subtract. If he purchases pieces, we add. So we have: 600 - 100 - 82 - 25 - 40 + 400 - 41 - 39 - 44 = [B]629 feet[/B]

Answer an electrician charges a base fee of $75. plus a $50 for each hour of work. The minimum the electrician charges is $175. Create a table that shows the amount the electrician charges for 1,2,3, and 4 hours of work. The hourly cost for h hours worked is C(h): C(h) = Max(175, 50h + 75) 1 hour cost: C(1) = Max(175, 50(1) + 75) C(1) = Max(175, 50 + 75) C(1) = Max(175, 125) [B]C(1) = 175[/B] 2 hour cost: C(2) = Max(175, 50(2) + 75) C(2) = Max(175, 100 + 75) C(2) = Max(175, 175) [B]C(2) = 175[/B] 3 hour cost: C(3) = Max(175, 50(3) + 75) C(3) = Max(175, 150 + 75) C(3) = Max(175, 225) [B]C(3) = 225[/B] 4 hour cost: C(4) = Max(175, 50(4) + 75) C(4) = Max(175, 200 + 75) C(4) = Max(175, 275) [B]C(4) = 275[/B]

Free Direct Current (Electrical Engineering) Ohms Law Calculator - Enter two of the following items from the DIRECT CURRENT(DC) electrical engineering set of variables, and this will solve for the remaining two:
* I = current(amps.)
* V = Electricity potential of voltage(volts)
* R = resistance(ohms)
* P = power(watts)

Jerry, an electrician, worked 7 months out the year. What percent of the year did he work? We know that there are 12 months in a year. Percentage worked = Months worked in a year / months in a year * 100% Percentage worked = 7/12 * 100% Percentage worked = 0.5833333 * 100% Multiplying by 100 means we shift the decimal place 2 spaces to the right: Percentage worked = [B]58.33%[/B]

Sara bought a gas-electric hybrid car. She traveled 481.25 miles and used 9.625 gallons of gas. How many miles did the hybrid car travel for each gallon of gas? 481.25/9.625 = [B]50 miles per gallon[/B]
