Answer:
10 - A(t)/(1000 + t)
Step-by-step explanation:
salt enters the tank at the rate of 9 liters per minute, and is pumped out at 10 liters per minute.

V(0) = 1000 liters
V(t) = 1000 + t.
Let A(t) be the amount of salt in gram at time t
The concentration of salt entering the tank is 120 grams/liters.
grams/liters is the concentration of the salt that is being pumped out of the tank at time t
= 1 * 10 - A(t)/(1000 + t)
= 10 - A(t)/(1000 + t)

Answer:
Step-by-step explanation:
-2 < -3/4. Another way in which to do this would be to use the LCD:
-8/4 < -3/4.
Even though 8 has a larger magnitude than does 3, -8/4 is smaller than -3/4. On the number line, -8/4 (or -2) is to the left of -3/4.
Answer: No
Step-by-step explanation:
I took a test and this answer was correct.
-10 -10y = 10
+10 +10
-10y = 20
20/-10 = -2
Y = -2
