9am to 4 pm is 7 hour and you use the total cost divid by hours you can get you answer which is 4.12 per hour
13 = r/9 + 8
subtract 8 from each side
5 = r/9
multiply 9 from each side
r = 45
Answer:
log(5/4)
Step-by-step explanation:
You have to apply the properties of logarithms to the given expression in order to obtain a form with a single logarithm.
For example, the quotient rule:
![log(\frac{x}{y}) = log(x) - log (y)](https://tex.z-dn.net/?f=log%28%5Cfrac%7Bx%7D%7By%7D%29%20%3D%20log%28x%29%20-%20log%20%28y%29)
In this case, log(x) = log (5/6 ) and log(y)= log (2/3)
Therefore x = 5/6 and y = 2/3
Applying the rule:
log (5/6 )− log (2/3) = ![log(\frac{5/6}{2/3})](https://tex.z-dn.net/?f=log%28%5Cfrac%7B5%2F6%7D%7B2%2F3%7D%29)
Solving the argument of the logarithm (The division of the fractions)
![\frac{5/6}{2/3} = \frac{(5)(3)}{(6)(2)} =\frac{15}{12} =\frac{5}{4}](https://tex.z-dn.net/?f=%5Cfrac%7B5%2F6%7D%7B2%2F3%7D%20%3D%20%5Cfrac%7B%285%29%283%29%7D%7B%286%29%282%29%7D%20%3D%5Cfrac%7B15%7D%7B12%7D%20%3D%5Cfrac%7B5%7D%7B4%7D)
The equivalent form is:
log(5/4)
