Answer:

1.6KWh

Explanation:

La fórmula de la eficiencia del consumo energético es,

eficiencia = (salida / entrada) x 100

La eficiencia del aparato es = 70%

potencia en = 2,3 KWh

potencia de salida = vatios x (45 minutos / 60) veces en horas.

70 = (vatios(45/60) / 2,3 x 10 ^ 3) 100

0.7 = vatios(45/60) / 2,3 x 10 ^ 3     //dividir ambos lados por 100

1610 = vatios(0.75)                           //multiplica ambos lados por 2300

potencia de salida = vatios (0,75) = 1610/1000 = 1,6KWh

The answer that would best complete the given statement above would be option 5. The purpose of a method's postcondition is to describe the conditions that are true when the method completes. On the other hand, precondition describes the conditions that are true before the method is complete. Hope this helps.
