Answer:
0.0001042
Step-by-step explanation:
Power of tens rule states that if the denominator of a fraction has the positive power of 10, decimal in the numerator will be shifted to the left by the same number of places as exponent.
10⁴) 1.042 = 
In the denominator of the given fraction, exponent of 10 = +4
So the decimal in numerator will be shifted left by 4 places.

Therefore, answer is 0.0001042

Answer:
v = 120
Step-by-step explanation:
If v is inversely proportional to square root of d, then we can write
 = k
 = k     
If v  = 30 and d = 400, then
30( ) = k
) = k
k = 30(20) = 600
Now  = 600
 = 600
If d = 25, then v = 600
 = 600
                          5v = 600
                             v = 120
