For a resistor in a direct current circuit that does not vary its resistance, the power that a resistor must dissipate is direct
ly proportional ti the square of the voltage across the resistor. The resistor must dissipate 1/16 watt of power when the voltage across the resistor is 14 volts. Find the power that the resistor must dissipate when the voltage across it is 42 volts.
3 boxes of computer diskettes at $8.99 per box = (3 * 8.99 = 26.97 ) 2 packages of pens at $ 2.50 per package = (2 * 2.50 = 5.00 ) 6 boxes of paper at $ 22.95 per box = (6 * 22.95 = 137.70) 1 printer ribbon at $25 each. = (1 * 25 = 25) Add up (26.97+5.00+137.70+25 ) and the answer is = 194.67
