Mariela recolecto 625 mililitros de agua que gotea de su caño en 10 minutos, ella desea saber ¿cuanta agua gastara en una semana
mario62 [17]

Answer:

En una semana gastará 705,6 litros.

Step-by-step explanation:

Con la información proporcionada, puedes calcular cuánta agua gastará por día usando una regla de tres teniendo en cuenta que un día tiene 24 horas y estas equivalen a 1440 minutos. Además, puedes convertir los 700 ml a litros, considerando que 1 litro son 1000 mL, lo que significa que los 700 mL equivalen a 700/1000=0,7 Litros.

 10 min    →  0,7 L

1440 min →       x

x=(1440*0,7)/10

x=100,8 L

Ahora que conoces la cantidad de agua que gastará por día, puedes multiplicar esta cantidad por 7 que es el número de días en una semana:

100,8*7=705,6 L

De acuerdo a esto, la respuesta es que en una semana gastará 705,6 litros.

If a car is depreciated in four years, what's the rate of depreciation using twice the straight-line rate?
Ulleksa [173]

Answer:

The rate of depreciation is 50%

Step-by-step explanation:

We are given

a car is depreciated in four years

so, depreciation in 1 year is

=\frac{1}{4}

the rate of depreciation using twice the straight-line rate

so, we will multiply by 2 and then we can find rate of depreciation

so, rate of depreciation is

=2\times \frac{1}{4}\times 100

=50%
