Answer:
0.5amps
Step-by-step explanation:
I is inversely proportional to resistance
I = k/R
k = I/ R
k = 20/5
k = 4
This means that, I = 4/R
So, when R = 8ohms,
I = 4/8
  =0.5amps
 
        
             
        
        
        
Answer:
 
       
Step-by-step explanation:
We are given the following in the question:
Volume of cake = 351 cubic inches
Let x inches be the width of cake.
Width of cake, w = 

Then, length of cake,l = 

Height of cake,h = 

Volume of cake = Volume of cuboid

Putting values, we get:

Thus, dimensions of cake are:

 
        
             
        
        
        
Is 0 one of your answer options? If so the answer is 0.
        
             
        
        
        
15 x 3 = 45 - 5 = 40 
The number will be 15.
Hope this helped.
