Answer:
-2/3
Step-by-step explanation:
Log125(1/25)=x
Raise each side to the base of 125
125^Log125(1/25)=125^x
1/25 = 125^x
Rewrite 25 as a power of 5  and 125 as a power of 5
1 / 5^2 = 5^3^x
The if power is in the denominator, we can bring it to the numerator by making it negative
5^-2 = 5^3^x
We know that a^b^c = a^(b*c)
5^-2 = 5^(3*x)
Since the bases are the same, the exponents are the same
-2 = 3x
Divide by 3
-2/3 = 3x/3
-2/3 =x
 
        
             
        
        
        
Hi!
Each piece cost 1.95, then 1000 pieces will cost:
1000 * 1.95 = 1950

$17.80 in 1 hr
$1 in 1/17.80 hr 
$675.00 in 675.00/17.80 hr 
 37.9 hours 
Which is 38 hours after rounding it.
