The amount of chlorine in a pool varies directly with the volume of water. the pool has 2.5 mg of chlorine per liter of water. there are 8000g of water in the pool. how much chlorine is in the pool?

For 8000 g of water the amount of chlorine in the pool is 20 mg .

Step-by-step explanation:

Given as :

The pool has 2.5 mg of chlorine per liter of water

I.e The pool has 2.5 mg of chlorine per 1000 g of water

Let The amount of pool in 8000 g of water be x mg

So, From unitary method

∵ For 1000 g of water , The pool has 2.5 mg of chlorine

so,  For 1 g of water , The pool has mg of chlorine

∴ For 8000 g of water , The pool has × 8000 mg of chlorine

I,e For 8000 g of water , The pool has 2.5 × 8 mg of chlorine

Or, For 8000 g of water , The pool has 20 mg of chlorine

Hence for 8000 g of water the amount of chlorine in the pool is 20 mg . Answer

answer:

c. the third graph

step-by-step explanation:

we are given

since, we have to isolate x on anyone side

so, we can move all x terms on one side

subtract both sides by 2x

add both sides by 9

divide both sides by 4

we get
