Answer:D) 1 hr
Step-by-step explanation:
Given
Pump A and B can fill tank in 
Pump A and C can fill tank in 
Pump B and C can fill tank in 
Let A be the total hr taken A therefore rate of 
Let B be the total hr taken B therefore rate of 
Let C be the total hr taken C therefore rate of 
-----1
-----2
-----3
Adding 1,2 & 3



thus time taken by A,B and C combined is 1 hr
Answer:
Is this an exam? looks like it
Step-by-step explanation:
I don't know if the first set of numbers is all in one set, but I'll do my best to give you an answer.
Really all you need to do is use PEMDAS for the first question.
(Parentheses, exponents, multiply, divide, add, subtract. In that order)

Then to simplify that fraction next to it, notice that 0.018 is 3x 0.06.
that's a 3:1 ratio, so it ends up simplifying to this:

Lastly, to solve the division of that fraction. If you divide by a fraction, you multiply whatever it's dividing by its inverse.
So...

Answer: Choice A) $4500.33
---------------------------------------------------------------------
Explanation:
The formula you'll use is
F = P*(1+r)^t
where
F = final amount
P = initial amount
r = growth rate (in decimal form)
t = time in years
In this case,
F = unknown (this is what we're trying to figure out)
P = 3046
r = 0.05 (since 5% = 5/100 = 0.05)
t = 8
Plug those three known values into the formula and evaluate
F = P*(1+r)^t
F = 3046*(1+0.05)^8
F = 3046*(1.05)^8
F = 3046*1.4774554
F = 4500.3291484
F = 4500.33 ... round to the nearest penny
