The average weight of 3 containers A,B and C is 3.2kg. Container A is twice as heavy as container B. Containers B is 400 g heavi

dlinn [17]

Answer:

The weight of container C is 2.1kg.

Step-by-step explanation:

This question is solved using a system of equations.

I am going to say that:

x is the weight of container A.

y is the weight of container B.

z is the weight of container C.

The average weight of 3 containers A,B and C is 3.2kg.

This means that the total weight is 3*3.2 = 9.6kg. So

$x + y + z = 9.6$

Container A is twice as heavy as container B.

This means that $x = 2y$ .

Containers B is 400 g heavier than container C.

400g is 0.4kg. So

This means that $y = z + 0.4$ , or $z = y - 0.4$

Replacing y and z as functions of x in the first equation:

$x + y + z = 9.6$

$2y + y + y - 0.4 = 9.6$

$4y = 10$

$y = \frac{10}{4} = 2.5$

Container C

$z = y - 0.4 = 2.5 - 0.4 = 2.1$

The weight of container C is 2.1kg.

The Rodriguez family and the Hill family each used their sprinklers last summer. The water output rate for the Rodriguez family'

brilliants [131]

Answer:

x = 23.33 hr Rodriguez sprinkler

y = 26.66 hr Hill sprinkler

Step-by-step explanation: INCOMPLETE QUESTION

Requiered information:

the water output rate for both sprinkler families

We assume : Rodriguez family 40 lts/hr

Hill family 35 lts/ hr

Total water output 1900 lts

and total combined hours working is 50 hr

Let call "x" time in hours sprinkler of Rodriguez family worked

and "y" time in hours sprinkler of Hill family worked

Then if total output was 1900 lts

40*x + 35*y = 1900 and x + y = 50

We have a two equation system, solving

y = 50 - x ⇒ 40*x + 35 * ( 50 - x )

40x = 1750 - 35x

75 x = 1750 ⇒ x = 1750/75 ⇒ x = 23.33 hr

and y = 50 - 23.33 ⇒ y = 26.66 hr
