A patient is to receive 1.08 L of fluid over 3 hours through an IV drip. There are 16 drops/ml. How many drops per minute are re
KATRIN_1 [288]
How many drops per minute?
There are 16 drops per ML.

1000 ML  =    1 L.
1L  =  1000 ML

Therefore 1.08 L  =  1.08 * 1000 = 1080 ML

16 drops  per ML means I ML has 16 drops.

Therefore 1080 ML has:    (1080 * 16) drops.

Number of drops per min:
Since the entire process took 3 hours =  3 * 60 minutes = 180 minutes.

Therefore Number of drops per minute  = Number of Drops / Time in minutes
                                                        = (1080 * 16) /(180)
                                                        = 96 drops per minute.

Can someone help me? thanks!
masha68 [24]
So you know that 1 cubic foot is equal to 80 pounds. So, the first point would be (1,80). 
You can find the other points by multiply 80 by a number, and when I did that, I got (2,160) and (3,240) too.

I hope this helps :)

Give an example of a point that is the same distance from (3, 0) as it is from (7, 0). Find lots of examples. Describe the confi
Artist 52 [7]

Supposse that the distance from the point (x,y) to the point (3,0) is equal to the distance from  (x,y) to the point (7,0). Then, by the formula of the distnace we must have

\sqrt{(x-3)^2 + (y-0)^2}=\sqrt{(x-7)^2 + (y-0)^2}

cancel the square root and the (y-0)^2's, and then expand the parenthesis to obtain

x^2 - 6x + 9 = x^2 - 14x + 49

then, simplifying we obtain

8x = 40

therfore we must have

x=5

this means that the points satisfying the propertie must have first component equal to 5. So we can give a lot of examples of such points: (5,0), (5,7),(5,1/2), (5,-10),.... The set of this points give us a straight line and the points (3,0) and (7,0) are symmetric with respect to this line.

Ashley had a summer lemonade stand where she sold small cups of lemonade for $1.25 and large cups for $2.50. if ashley sold a to
Levart [38]
The answer is 98 small and 57 large cups.

s - the number of small cups
l - the number of large cups

<span>Ashley sold a total of 155 cups: s + l = 155
</span><span>Ashley earned</span><span>for $265: 1.25 * s + 2.50 * l = 265

</span>s + l = 155
1.25 * s + 2.50 * l = 265
________
s = 155 - l
1.25 * s + 2.50 * l = 265
________
1.25 * (155 - l) + 2.50 * l = 265
193.75 - 1.25 * l + 2.50 * l = 265
193.75 + 1.25 * l = 265
1.25 * l = 265 - 193.75
1.25 * l = 71.25
l = 71.25 / 1.25
l = 57

______
s = 155 - l
l = 57

s = 155 - 57
s = 98
