We would need to use 4 pipes to be sure to empty the chamber within 10 hours time.
Work:
5*5/3*4/10=3 1/3 pipes (but we must round since we cant have 1/3 of a pipe running. This means that we must have 4 pipes.
Answer:
a. x=2, y=13
b. x=14, y=25
c. x=−4, y=13
Step-by-step explanation:
Let
C-----------------
> charges for the purchases to the credit card
<span>r-------------------
> the interest rate </span>
X------------------
> total cost of the purchase
we know that
C=4120
r= 22.45%=0.2245
X=C*(1+r)
substituting the values in the formula
X=(4120)*(1+0.2245)=
(4120)*(1.2245)=5044.94
the answer is
$5044.94
