If it dropped 2° every hour then after 3 hours it would drop (2*3=6) 6°
1/4 of 2 is 0.5 this will be added to the 3 hours to get the answer for 31/4 hours
6 + 0.5 = 6.5°
If there is a higher concentration of solutes outside of the cell than inside it, such as would happen if you placed red blood cells in a concentrated salt solution, then the salt solution is hyper-tonic with respect to the inside of the cells. So yes the Red Blood cell would be considered a hyper-tonic solution
<h2>Solution (a) :-</h2>
Quantity of flour needed to make 20 pancakes =
Then , number of pancakes that can be made from 1 cup of floor :-
.
Therefore , 12 pancakes can be made from 1 cup of floor .
<h2>Solution (b) :-</h2>
Number of pancakes that can be made with 1 cup of flour = 12 pancakes
Number of pancakes that can be made with 9 cups of flour :-
= 9 × 12
= 108 pancakes
Therefore , I can make 108 pancakes with 9 cups of flour .
<h2>Solution (c) :-</h2>
Yes , I have enough flour to make 100 pancakes . I say this because :-
With one cup of flour I can make = 12 pancakes
With 9 cups of flour I can make =
= 9 × 12
= 108 pancakes
As I can make 108 pancakes with 9 cups of flour , I can conclude that I have enough flour to make 100 pancakes .
