Answer:
Step-by-step explanation:
A tank contains 240 liters of fluid in which 20 grams of salt is dissolved.
- Volume of the tank = 240 liters
- Initial Amount of Salt in the tank, A(0)=20 grams
Brine containing 1 gram of salt per liter is then pumped into the tank at a rate of 6 L/min
(concentration of salt in inflow)(input rate of fluid)
(concentration of salt in outflow)(output rate of fluid)
Rate of change of the amount of salt in the tank:
We then solve the resulting differential equation by separation of variables.
Taking the integral of both sides
Recall that when t=0, A(t)=20 (our initial condition)
Any number greater than 700,000 with ten-thousands digit 1 through 4 will round down to 700,000. For example, 748,235 will round to 700,000.
Q represents the number of invitations without a response. Q is equal to 253
The easiest way to do this is to write the decimals with equal amount of places after the dot and you'll see it more clearly:
1.09 = 1.090
1.901 = 1.901
1.9 = 1.900
1.19 = 1.190
So from the least to the greatest:
1.090
1.190
1.900
1.901
In a form you gave at the beginning:
1.09 < 1.19 < 1.9 < 1.901
Answer:
3/4, 5/6, 8/10 this is in fraction form though. just change it to 3:4
