Answer: B : Mean Does Not change
Step-by-step explanation:
Answer:
Can't really read that but these would work
f = 12h
h = f/12
Step-by-step explanation:
This is a system of equations. The first equation represents the tank being emptied and the second equation represents the tank being filled:
k = -10t + 528
k = 14t
To solve this system of equations, we will use substitution. The second equation says that k is equal to 14t, so we can substitute 14t for k in the first equation.
14t = -10t + 528
24t = 528
t = 22
Now that we have t, we can use it to find k by plugging it in to the second equation:
k = 14(22)
k = 308
So, it will take 22 minutes for both tanks to hold equal amounts of water. They will each hold 308 kiloliters.
Nope - 320 millimetres = 32 centimetres. 3.2 metres is 320 centimetres, which is 3,200 millimetres
