Mario's unit rate is given by 900 miles/hour.
Explanation:
We have been given that Mario walked at a rate of 2/3 miles every 10 minutes.
We have the relation between speed, time and distance, which is given by
We have,
Distance = 
Time = 10 minutes
On substituting these values in the above formula, we get
![\text{Speed} = \frac{2/3}{10}\\\\ \text{Speed} =\frac{2}{10\cdot 3}\\\\ \text{Speed} =[tex]\frac{1}{15}](https://tex.z-dn.net/?f=%5Ctext%7BSpeed%7D%20%3D%20%5Cfrac%7B2%2F3%7D%7B10%7D%5C%5C%5C%5C%20%5Ctext%7BSpeed%7D%20%3D%5Cfrac%7B2%7D%7B10%5Ccdot%203%7D%5C%5C%5C%5C%20%5Ctext%7BSpeed%7D%20%3D%5Btex%5D%5Cfrac%7B1%7D%7B15%7D)
\text{ miles/min}[/tex]
We have to find the unit rate in mile per hour, so we need to multiply it by 60
Thus, unit rate is given by
Answer:
The expression used to represent g(x) as inverse of f(x) is 
Option B is correct.
Step-by-step explanation:
We are given:
We need to find the expression that could be used to verify g(x) is the inverse of f(x).
We know that 
is inverse of function
So placing value of f(x) in g(x)
So, the expression used to represent g(x) as inverse of f(x) is
Option B is correct.
We can also solve to prove that
Step-by-step explanation:
1 pound = 16 ounces
5 pound = 16 x 5 = 80
Cost per ounce = 15
Cost of 80 ounces = 15 x 80 = 1200
Option D is the correct answer
