Answer:
6
Step-by-step explanation:
(2.4×10³)×(3×10^x)=7.2×10^9
(3x10^x)=(7.2×10^9)/(2.4×10^3)
3×10^x=3×10^6
10^x=10^6
*when bases are same ,powers are equated*
thus x=6 
 
        
             
        
        
        
Answer:
(st)(6)= s(6) * t(6)
Step-by-step explanation:
(st)(6)
(st)(x)= s(x) * t(x) we multiply it
(st)(6)= s(6) * t(6)
Hope this helps.
 
        
             
        
        
        
Answer:  12 minutes
Step-by-step explanation:
Two rates for hoses A and B.  FP is the Fish Pond.
A = 20 min/FP   or (1/20)FP/min
B = 30 min/FP   or (1/30)FP/min
The time in minutes, X,  to fill  one FP:
                      1FP = X*((1/20)FP/min) + X*((1/30)FP/min)  
                      1FP = X*(1/20+1/30)FP/min
                      1FP = X*(2.5/30)FP/min
                       X = 12 minutes
