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{ 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:
1) The domain In interval notation is [0, 20]
2) The range in interval notation is [100, 700]
Step-by-step explanation:
The given parameters are;
The amount Beth saved per month = $30
The number of months Beth saved = 20 months
The amount with which Beth opened her account = $100
Therefore, the amount of money Beth saved with respect to time is given as follows;
Y = $100 + $30 × X
Where;
Y = The amount of money Beth saved
X = The time (number of months) Beth saved
The domain is given as follows;
The domain in interval notation is [0, 20]
For the range, when X = 0, Y = $100
When X = 20, Y = $100 + $30 × 20 = $700
Therefore, the range is given as follows;
Which the range in interval notation is [100, 700].
