Step-by-step explanation:
Answers:
a) 75ml/hr
b) 0ml left
Explanation:
a) 750ml - 450ml = 300ml (This is how much we know the bag drained within 4hrs)
300ml/4=75ml
so now we know the rate of drain is 75ml/hr
b) since rate is 75ml/hr:
75*6=450
450-450=0
Hence there will be no fluid left for the patient.
The answer is
51-17i
Explanation :
5x95x2i-3ix9-3ix2i
45+10i-27i-6^2
45+10i-27i-6(-1)
45+10i-27i + 6
Given:
Charlie bought a new computer for $450 with his credit card.
He plans to pay the minimum payment of $25 per month.
To find:
The rate of change.
Solution:
Let y be the remaining amount of loan after x months.
Initial amount of loan = $450
Payment of one month = $25
Payment of x months = $25x
Now,
Remining amount = Initial amount of loan - Payment of x months
...(i)
The slope intercept form is
...(ii)
where, m is slope and b is y-intercept.
From (i) and (ii), we get

Therefore, the rate of change is -25 dollars.
