heather has divided $6300 between two invesments, one paying 9%, the other paying 4%. If the return on her investment is $372, h
Ganezh [65]
Assuming that the two investments are  X & Y
X + Y = 6300
X = 6300 - Y                                       (1)

9/100X + 4/100 Y = 372                       (2)
replacing X from (1) into (2)
9/100(6300-Y) + 4/100 Y = 372
567 - 9/100Y +4/100Y = 372
(-9+4)/100Y = 372 - 567
5/100Y = -195
Y = 100*195/5 = 3900
From (1) we can get X
X = 6300 - 3900 = 2400

I hope this is helpful

1.<br> A patient is told to force fluids to 3 L/day. How many mls should she drink?
Damm [24]

The patient should drink 3000 milliliter per day

<em><u>Solution:</u></em>

Given that a patient is told to force fluids to 3 liter per day

To find: Amount the patient should drink in milliliter

Use the conversion factor,

1 liter = 1000 milliliter

Now we have to find the amount the patient she drink in milliliter

Amount patient drinks in liter = 3 liter per day

Therefore, convert 3 liter to milliliter

3 liter = 1000 x 3 milliliter = 3000 milliliter

Thus the patient should drink 3000 milliliter per day
