Y varies directly with x means
y=kx or
y/x=k
see if that's true for all of them, if they all have same k value, it is direct variation
24/32=3/4
8/16=1/2
6/8=3/4
no
D is answer
By using the calculator, log 6 = 0.7781...
log 60,000 is just equal to log (6 * 10,000)
log (6 * 10,000) = log 6 + log 10,000
As we know that log 10 = 1, log 100 = 2, log 1000 = 3, and so on.
So log 10,000 = 4
Going back to our equation,
log (6 * 10,000) = log 6 + log 10,000
log 60,000 = 0.7781 + 4
So log 60,000 = 4.7781
