Answer:
1) 28.4 miles per gallon
2) 34 miles per gallon
3) the silver car
Step-by-step explanation:
We have the following information:
Blue car:
Travels 35 1/2 miles on 1 1/4 gallons of gasoline
Silver car:
Travels 27 1/5 miles on 4/5 gallons of gasoline
We want to know the unit rate for miles per hour, and to do it we have to divide the miles they travel by the gallons each car uses:
Blue car:
(35 1/2) / (1 1/4) = 28.4 miles per gallon
Silver car:
(27 1/5) / (4/5) = 34 miles per gallon

<h2>
Hello!</h2>
The answer is:
Benji requires 90mL per injection.
<h2>Why?</h2>
From the statement we know that dog's weight is 12 kg, and daily injections are required for 3 days, the dose rate is 7.5 mg/kg, so we need to calculate how many mL per injection does Benji require.
We have that:
If the dose rate is 7.5 mL per each Kg, how many mL are required for 12 Kg? We can set it up using the following relation:
Hence, we have that there are needed 90 mL per injection.
Have a nice day!
Answer:
Step-by-step explanation:
Use the exponential growth formula
Where A is the final amount in the account, P is the initial amount, r is the growth rate and t is the time in years
In this problem
We know that
So
Finally after 5 years the balance of the account is:
