Answer:Whats the highest number each number can go up to before it rounds up? Its +4 as each number will round up otherwise. So if the rounded up numbers were 10,20,30,30. They can go up to 14,24,34,34. So its 106.please mark as brainliest
Step-by-step explanation:
3+3+3-3=6
(3+3+3-3)÷2=3
(3+3+3+3)÷3=4
(3+3+3+3)÷6=2
Is this how it works?
Answer:
Therefore the concentration of salt in the incoming brine is 1.73 g/L.
Step-by-step explanation:
Here the amount of incoming and outgoing of water are equal. Then the amount of water in the tank remain same = 10 liters.
Let the concentration of salt be a gram/L
Let the amount salt in the tank at any time t be Q(t).

Incoming rate = (a g/L)×(1 L/min)
=a g/min
The concentration of salt in the tank at any time t is =
g/L
Outgoing rate =



Integrating both sides

[ where c arbitrary constant]
Initial condition when t= 20 , Q(t)= 15 gram


Therefore ,
.......(1)
In the starting time t=0 and Q(t)=0
Putting t=0 and Q(t)=0 in equation (1) we get









Therefore the concentration of salt in the incoming brine is 1.73 g/L
Answer: g > 0
