Answer:
12 liters
Step-by-step explanation:
The kerosene usage is assumed to be jointly proportional to the number of stoves and the number of hours. That is ...
v = k·s·h . . . . . for s stoves running h hours
Then the value of k is ...
k = v/(sh) = (16 L)/(12·14) = 2/21 . . . . liters per stove-hour
Then the volume of kerosene required for 7 stoves and 18 hours is ...
v = (2/21)·s·h
v = (2/21)(7)(18) = 12 . . . liters

Answer:
Step-by-step explanation:
2. 24^2+7^2 = 625
V 625 = 25
3. 6^2 + 5^2 = 25 +36 = 61
V 61 =7.81024967 =7.8
4. 4^2 +9^2 = 97
V 97= 9.84885780 = 9.8
5. 2^2 +3^2 = 13
V 13 =3.60555127 =3.6
and done!
