First, we need to understand the speed formula:
The time used = distance ÷ rate
In this case, the time needed would be:
5 1/5 ÷ 2 1/6
= (5×5+1)/5 ÷ (2×6+1)/6
=26/5 ÷ 13/6
When there is division in an equaiton, we can swap the nominator and denominator of the fraction amd change it to multiplication:
=26/5 × 6/13
= (13 x 2)/5 x 6/(13 x 1)
Factorize 26 and 13,we get:
=2/5 x 6/1
= 12/5 ft or 2.4 ft
Therefore the answer is 12/5ft or 2.4ft.
Hope it helps!
        
             
        
        
        
The substitution property of equality, one of the eight properties of equality, states that if x = y, then x can be substituted in for y in any equation, and y can be substituted for x in any equation.
        
             
        
        
        

 will be increasing on the intervals where 

 and decreasing wherever 

. Local extrema occur when 

 and the sign of 

 changes to either side of that point.

 is positive when 

 is between -4 and some number between -2 and -1, and also 2 (exclusive) and 4, so you can estimate that 

 is increasing on the intervals [-4, -2] and (2, 4].

 is negative when 

 is between some number between -2 and -1, up to some number less than 2. So 

 is decreasing on the interval [-1, 1].
You then have two possible cases for extrema occurring. The sign of 

 changes for some 

 between -2 and -1, and again to either side of 

.
 
        
             
        
        
        
Answer:
82
Step-by-step explanation:
because 63% of 130 is 81.9
and since the question is asking approximately which means rounding, so you round 81.9 to get 82.  
 
        
             
        
        
        
The answer is yes.
Its yes because it exactly one input(x) & multi outputs(y). <span />
