<u>Answer:</u>

Option(A)

The container contains 12 grams of water and no ice

<u>Explanation:</u>

When the student kept the ice in the container, the ice starts to melt as the air temperature around the ice is warmer than the temperature of the ice itself.

The solid particles in the ice absorbs the heat from the air, allowing the particles in the ice to move freely. Hence, melting takes place and the student finds water and no ice in the container.

I need help what is s-1/3=7/9???? please help guys and thank you
nalin [4]

Answer:

10/9

Explanation:

First, let's convert 1/3 and 7/9 so that the have the same denominator. To do this let's find the least common multiple of 3 and 9.

List the multiples of 3 and 9:

3: 3, 9

9: 9

They have a least common multiple of 9

We need to convert 1/3 so it has a denominator of 9:

1/3*3/3 (we can multiply it by 3/3 because any number over itself is 1) = 3/9

s-3/9=7/9

Add 3/9 to both sides to isolate s

s=10/9
