3.45 x 10^5. That’s the answer
Answer:
a)
b)
Step-by-step explanation:
It can be seen in the graph that the water velocity and solution velocity is the same, but the salt concentation will be lower
Water velocity
Solution velocity
Brine concentration =
a) Amount of salt as a funtion of time Sa(t)
b)
This value was to be expected since as the time passes the concentration will be lower due to the entrance to the pure water tank
Answer:
B. 2.2
Step-by-step explanation:
hope this helps
Answer:
57
Step-by-step explanation:
3^r = 19
Multiply each side by 3
3 * 3^r = 19 *3
We know that a^b * a^ c = a^ ( b+c)
3^1 * 3^r = 19 *3
3^(r+1) = 19*3
3^(r+1) = 57
I'm pretty sure the rule is that anything divided by 0 is 0, lol at least that is what I learned when I was in middle school a couple years ago.
