Answer:

21 gallons.

Step-by-step explanation:

Let the number of gallons that the tank holds be x gallons.

1/2x + 7 = 5/6 x

5/6x - 1/2x = 7

5/6 x - 3/6 x = 7

1/3 x = 7

x = 21.

Elanso [62]

El volumen de un recipiente es igual al volumen de agua que puede contener el recipiente.

Por lo tanto, se necesitan <em>3000 minutos</em> o <em>50 horas</em> para que la piscina se llene de agua del grifo.

  • El volumen de agua que puede contener una piscina: 45.000 litros

  • Tasa de agua que sale de un grifo: 15 litros por minuto

  • El tiempo que tardará en llenarse la piscina se calcula como:

Cruz multiplicar

45.000 litros x 1 minuto / 15 litros

= 3000 minutos

  • También puede convertir 3000 minutos en horas

60 minutos = 1 hora

3000 minutos =?

Cruz multiplicar

3000 minutos x 1 hora / 60 minutos

= 50 horas

Por lo tanto, se necesitan 3000 minutos o 50 horas para que la piscina se llene de agua del grifo.
