Peter jogs 3 miles in 27 minutes. Find the unit rate in minutes per mile.
2 answers:
Answer: 1 mile per 9 minutes or 9 minutes per mile
Step-by-step explanation: "Per mile" means in 1 mile so we can rewrite the given statement using fractions.
To find out what goes in the blank, notice that we have a 1 in the denominator of our second fraction so we want to find a fraction that is equivalent to 27/3 that has a 1 in the denominator.
If we divide the numerator and denominator of 27/3 by 3, we get the equivalent fraction 9/1 or 9 minutes over 1 mile.
So now we have 9 minutes over 1 mile = ___ minutes over 1 mile.
So a 9 must go in the blank.
Therefore, the unit rate for 3 miles in 27 minutes is 1 mile per 9 minutes or 9 miles in 1 minute.

Answer:
$295.295
Explanation:
Of the statement, we have that the price of the machine decreased 10% every year exponentially, so in the first year it real value drops to 90% of the costs. For 5 years, It can be expressed and simplified by the following equation:
We can't use that the percent drop as a percent itself, so we are going to divide 90% by 100%, and it will give us an entire number.
By substituting we have:
Value: $295.245
