It would be 40 in. If you think about it the 4in is 10 % and it is asking for the 100%. So to get to 100% you can do 4in *10= 40in
I hope this helps and it is okay! Hard to pay attention sometimes!

Answer:
Viruses are 2 times of the bacteria.
Step-by-step explanation:
Given:
Number of viruses =  
 
Number of bacteria = 
We have to found how many times viruses are greater than the bacteria.
To find how many times,we can divide both the numbers to compare its values.
Lets 
Numerator = Number of viruses
Denominator = Number of bacteria
Dividing both we have,
⇒ 
⇒  ...
 ...
⇒  ...
       ...
⇒ 
So the viruses are 2 times of the bacteria.
 
        
                    
             
        
        
        
Answer:
"Perfect square trinomials" are quadratics which are the results of squaring binomials. (Remember that "trinomial" means "three-term polynomial".) 
For instance:
(x + 3)2
= (x + 3)(x + 3)
= x2 + 6x + 9
...so x2 + 6x + 9 is a perfect square trinomial.
