Answer:
3 gallons per mile, slope of 3
Step-by-step explanation:
To find out how many gallons the train uses per mile, look at the point (50,150). If you know that the train used 150 gallons to travel 50 miles, do 150/50 to get an answer of 3 gallons per mile.
For the second part, you know that as x increases by 1 (miles traveled) y (gallons) increases by 3, so therefore the slope is 3. You can also check this value by plugging in the points (150,450) and (50,150) into the
Answer:
20.33%
Step-by-step explanation:
Principal = $2650
Total Interest = $300
Total amount = 42650+$300=$2950
Since we are given that You paid off the loan in 1 year by making 12 monthly payments
So, monthly payment =
Formula of monthly payment =
where i is the rate of interest in decimals
To find i substitute the values
using calculator
So, rate of interest in percent =
Thus the annual percentage rate (APR) is 20.33%
Answer:
if she has 17 quarters, the money of it would be $4.25.
$5.05 - 4.25$ = $0.80
=> 8 dimes
=> she have 17 quarters and 8 dimes
Step-by-step explanation:
The answer is 2X because they have 2 twos in common and an X
X=32 because both equations are equal to 180 degrees (3x+22°+x+30°=180) just solve that equation and you’ll get your answer
