Answer:
80
Explanation:
46 + 37 = 83 so 83 rounded to the nearest 10 is 80
Answer:
C
Step-by-step explanation:
proportion can be used to show that the slope of AC is equal to the slope of CG
Slope of AC = (2-0)/(3-0) = 2/3
Slope of CG = (6-2)/(9 -3) = 2/3
So answer is :
C)
2 − 0 6 − 2
------------ = -----------
3 − 0 9 − 3
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)
