Answer:
Because many objects are not regularly shaped their volume cannot be determined using a volume formula. The volume of these objects can be found by water displacement. A volume of water sufficient to cover the object is placed in a graduated cylinder and the volume read. The object is added to the cylinder and the volume read again. The difference between the two volumes is the volume of the object. This method is demonstrated using the same battery used above.

Answer:
Costo fijo= $104.5
Costo unitario= $0.5 por minuto
Step-by-step explanation:
Mes pasado:
$239 por 269 minutos
Mes corriente:
$175 por 141 minutos
<u>Primero debemos calcular el cost por minuto de llamada:</u>
Costo unitario= (costo total más alto - costo total más bajo) / (cantidad de minutos más alto - cantidad de minutos más bajo)
Costo unitario= (239 - 175) / (269 - 141)
Costo unitario= $0.5 por minuto
<u>Ahora, el costo fijo:</u>
Costo fijo= costo total más alto - (costo unitario*cantidad de minutos más alto)
Costo fijo= 239 - (0.5*269)
Costo fijo= $104.5
Costo fijo= costo total más bajo - (costo unitario*cantidad de minutos más bajo)
Costo fijo= 175 - (0.5*141)
Costo fijo= $104.5
