Answer: 
the answer is d.
Step-by-step explanation:
first, you want to use the formula, 
new value - original value 
<u>____________________</u>
          original value              * 100
you see that 84 is the new value and 79 would be the original value. substitute the numbers in. this is a increase since you will get a positive value.
84 - 79
<u>______</u>
    79      * 100
now we solve it. 
5
<u>__</u>
79  * 100
you can either solve the fraction first then multiply that by 100 or multiply the numerator by 100 first then divide that by 79, each way works.
500
<u>____</u>
  79   =  approximately 6.3% increase (this is not a exact value, just rounded)
       or 
5
<u>__</u>
79  = approximately 0.063 (this is not a exact value, just rounded)
0.063 * 100 = 6.3% increase

Answer:
Fluffy's tail is 1/12 of a meter longer than Fireball's tail.
Step-by-step explanation:
1 1/3 - 1 1/4 = x
get common denominator (12)
1 4/12 - 1 3/12 = 1/12
 
        
             
        
        
        
Answer:
Decay
Step-by-step explanation:
We are given an equation 
We need to say about decay or growth of exponential function. 
Exponential function: 
Where, 
- a is initial value of exponential function. 
 - b is decay or growth of function
 
For decay: 0<b<1 
For growth: b>1
Now we rewrite the equation into this form 

Changes to 

Here, b=0.5 < 1 
Therefore, The given function would be decay. 
Thus, 
 is deacy.
