Answer:
C
Any time you have a subtraction and a negitive right next to eachother, it means to add. So, you would add 13 and 1 to get 14, then keep the denominator 19 to get 14/19.

Answer:
 8 inches
Step-by-step explanation:
Given: Dimension of rectangular container= 
            Water is filled up to a level 2 inches from the top.
As given that container is sitting on its largest face, then it is standing on 
Which means the height of container is 6 inches and it ie filled with water up to 2 inches from the top.
∴ Height of water inside the container= 
Now, finding the volume of water inside.
we know, Volume= 
Volume= 
Next, if container is placed in its smallest face then it is standing on  and lets assume height to be "x"
 and lets assume height to be "x"
Forming an equation now to express the volume conservation law.
⇒ 
⇒
dividing both side by 60
⇒
∴ x= 8 inches
Hence, 8 inches from the bottom will the water level reach if the container is placed on its smallest face
 
        
             
        
        
        
1520.53
Step-by-step explanation:
V = pi * r^2 * h
the radius is half of the diameter and 11/2 = 5.5
V = pi * 5.5^2 * 16
V = 1520.53
