Answer:
22.67 containers.
Step-by-step explanation:
The number of cars washed is the average by the total hours worked:
Given that each car uses 1/3 tin of wax, the total containers is calculated as:
Hence, the car wash uses 22.67 containers of wax per day.

Answer:
lnx/ln4
Step-by-step explanation:
Given
y=4^x
In order to find the inverse of the function the first step is to replace the y with x and x with y
So,
Replacing x with y and y with x
x= 4^y
We have to find the value of y explicitly to find the invers.
The above equation can also be written as:
4^y=x
As the variable is in exponent, to bring it down, ln has to be taken on both sides.
ln 4^y =ln x
The power of will be multiplied with the ln.
y ln4=lnx
y=lnx/ln4
So,
The inverse is lnx/ln4 ..
Mass = density x volume
Mass = 3.5 x 20 = 70 grams
