Question

water is flowing into a water tank at the rate of 20 cubic cm/sec. if the volume of water collected in x seconds is y cubic cm. write the linear equation . write the volume of water after 5 seconds

Answer 1

First eq. will be x+y=20
(x+5)+y=20+5 will be second eq.

Answer 2

Answer:

The required linear equation is : y = 20x

Volume of water after 5 seconds = 100 cm³

Step-by-step explanation:

Volume of water collected in tank in 1 second = 20 cm³

Volume of water collected in tank in x second = 20x cm³

Now, it is given that volume of water collected in tank in x second is y cm³

So, the required linear equation is : y = 20x

Now, volume of water after 5 sec : so x = 2

⇒ y = 20 × 5

⇒ y = 100 cm³

Hence, Volume of water after 5 seconds = 100 cm³
