Answer:
1/18
Step-by-step explanation:
10 over 180 (60 minutes * 3 hours) = 10/180 = 1/18
Functions can be represented on graphs
The value of f(k + 3) is 0
Given that:

From the graph, we have:

So, by comparison:

Substitute 2 for k in f(k + 3)


From the graph, f(5) = 0
So, we have:

Hence, the value of f(k + 3) is 0

Answer:
5
Step-by-step explanation:
- 2×1/2 + 4×(4×2 - 7) = ⇒ multiplication
- 1 + 4×(8 - 7) = ⇒ parenthesis
- 1 + 4×1 = ⇒ multiplication
- 1 + 4 = ⇒ addition
- 5 ⇒ answer
Answer:
The correct option is B) 12.
Step-by-step explanation:
Consider the provided information.
Working alone at its constant rate, pump X pumped out ¼ of the water in a tank in 2 hours.
As we know:
,
The rate of pump X is 
of the water is pumped out of the tank, that means only
is left to be pumped out.
All 3 pumps pumped out the remaining
of the water out in 3 hours.
The combined rate of all three pumps is:
Pump Y, working alone at its constant rate, would have taken 18 hours to pump out the rest of the water.
The rate of pump Y =
Let z is the time taken by pump Z, then the rate of pump Z is
.
Therefore,

Multiplying both sides by 24 z.

Hence, the correct option is B) 12.
