As the sum of marks of others remain unchanged , let their sum be x . As the mean using 83 was 40 , we have ,
(x +83)/100 = 40
x + 83 = 4000
x = 3917
Now mean using 53 ,
(x +53)/100
(3917+53)/100
39.7.
Hope it helps , plz mark as brainiest :-)
Answer:
<u>7550 ml</u> of soup Gina have left to freeze.
Step-by-step explanation:
Given:
Gina made 9350ml chicken noodle soup, she packed 1.8l of soup in her kids lunches.
She froze the rest of the soup.
Now, to find the ml of soup Gina have left to freeze.
<u><em>The total quantity of soup Gina made = 9350 ml.</em></u>
Quantity she packed for lunches = 1.8 l.
Now, we convert l into ml by using conversion factor:
1 l = 1000 ml.
1.8 l = 1.8 × 1000 ml.
1.8 l = 1800 ml.
<u><em>Thus, the quantity she packed for lunches = 1800 ml.</em></u>
Now, to get the ml of soup Gina have left to freeze we subtract the quantity she packed for lunches from the total quantity of soup she made:

Therefore, 7550 ml of soup Gina have left to freeze.
