Yoko's fish tank has 17 liters of water in it. She plans to add 5 liters per minute until the tank has at least 57 liters. What are the possible numbers of minutes Yoko could add water?
Answer:
Minutes = 8 minutes
Step-by-step explanation:
Topic: Inequality
Given:
Available Size of water = 17 liters
Increment = 5 liters/minute
Size of water needed = At least 57 liters
Putting the above together, as have
17 + 5m > 57
where m represents total minutes and > represent at least
Solving the Inequality
5m > 57 - 17
5m > 40 ------ Divide through by 5
5m/5 > 40/5
m > 8
So, Yoko will need to add water for at least 8 minutes before she fills her tank to 57 liters.
Answer:
T-.5 = x (200)
Step-by-step explanation:
Let T = total time in hours
30 mn = .5 hours 30
/60
=
.5
$ 2.00 is the rate per hour.
so T
−
.5
= the time that will be charged at the rate
Therefore the total charge is then
T
−
.5
×
2.00
