Gonzalo observa que el grifo del lavabo de un año después el goteo se produce una velocidad de una gota por segundo y cada gota
Sergio [31]

Answer:

La familia de Gonzalo ha despilfarrado 15,768 litros de agua.

Step-by-step explanation:

Dado que Gonzalo observa que el grifo del lavabo gotea luego de un año, y el goteo se produce una velocidad de una gota por segundo y cada gota contiene 0.5ml de agua, para determinar cuántos litros de agua ha despilfarrado la familia de Gonzalo desde que ellos se dieron cuenta de la avería se debe realizar el siguiente cálculo:

1 año = 365 dias x 24 horas x 60 minutos x 60 segundos

0.5 x 60 x 60 x 24 x 365 = X

30 x 60 x 24 x 365 = X

1800 x 24 x 365 = X

43,200 x 365 = X

15,768,000 = X

15,768,000 / 1000 = X

15,768 = X

Por lo tanto, la familia de Gonzalo ha despilfarrado 15,768 litros de agua.

An organization will give a prize to a local artist. The artist will be randomly chosen from among 3 painters, 7 sculptors, and
umka2103 [35]
So we have 10 painters and sculptors all together. There are also 22 people in total. That means we have a 10/22 chance it will be one of those artists. This fraction can be reduced to 5/11.

A water tank, having the shape of a rectangular prism of base 100 square centimeters, is being filled at the rate of 1 liter per
aleksley [76]
The volume of a rectangular prism is given by 
area of base × height 
The rate at which the tank is being filled is 1 liter per minute which we need to convert 
1 liter = 1 dm³
But 1 dm = 10 cm. Hence 
1 liter = (10 cm)³ = 1000 cm³
The height h of the water is related to the volume by 
volume = area of base × h 
In one minute the volume increases by 1 liter or 1000 cm³ and the height increases by 
h = volume / area of base = 1000 cm³ / 100 cm² = 10 cm <span>

Pls help 9th grade math
loris [4]

Inequalities will have a <, >, <=, =>, = or will be worded as "Less than", "greater than", etc.

Equations must have mathematical functions and equal sign.

15=3x is an equation since 3x = 3*x

Finally, expressions are mathematical functions that have no equal signs.
