I think Mr. Han is around the 60 or 70 age.
I am really sorry that I couldn't answer this problem. Try starting with 21 and multiply that by 3. To check if you can do it, add 43 to the number you multiply 3 with. Again, i am really sorry that i only wrote a hint. Good luck finding the answer!
Answer: 1 ) 20.58 cm^3
2 ) $0.09
3 ) $ 0.41
Step-by-step explanation:
Answer:
g = 15 - m/28
Step-by-step explanation:
let g = gasoline
let m = miles
since you can drive 420 miles with 15 gallons of gas, you can drive 28 miles with one gallon (= 420/15 = 28)
e.g.
you drive 100 miles, then you will have:
g = 15 - 100/28 = 15 - 3.57 = 11.43 gallons of gas left
you drive 240 miles:
g = 15 - 240/28 = 6.43 gallons
To solve this problem you must appply the formula for simple interest, which is:
I = RxPxN
I: Simple Interest.
R:Rate (9.5$/100=0.095/12).
P: The principal (P=$9000).
N:number of periods (N=24).
When you substitute these values into the formula, you obtain:
I=RxPxN
I=(0.095/12)x9000x24
I=$1710
Therefore, the monthly payment is:
$1710/24=$71.25
