Sagot :
Answer:
300 centavos
Explanation:
De la pregunta anterior, se obtuvieron los siguientes datos:
Potencia (P) = 2500 W
Tiempo (t) = 8 horas
Costo de operación =?
A continuación, convertiremos 2500 W a KW. Esto se puede obtener de la siguiente manera:
1000 W = 1 KW
Por lo tanto,
2500 W = 2500 W × 1 KW / 1000 W
2500 W = 2,5 KW
Por tanto, 2500 W equivalen a 2,5 KW
A continuación, determinaremos la energía consumida. Esto se puede obtener de la siguiente manera: Potencia (P) = 2,5 KW
Tiempo (t) = 8 horas
Energía (E) =?
E = Pt
E = 2,5 × 8
E = 20 KWh
Finalmente, determinaremos el costo de operación. Esto se puede obtener de la siguiente manera:
1 KWh = 15 centavos
Por lo tanto,
20 KWh = 20 KWh × 15 centavos / 1 KWh
20 KWh = 300 centavos
Por lo tanto, costará 300 centavos tener un radiador de 2500 W encendido toda la noche (8 horas).
