OK.....but I think you messed up your question....
I will assume 65 drops/ min and 15 drops / ml how much time to 'drip out ' 1.6 liter
65 d/min / 15 d/ ml = 4.3333 ml/min
1600 ml /4.3333 ml/min = 369.23 min = 6 hrs 9.23 min
Area = pi r^2
Circ = pi d I would say you would use the pi key and the 'squared' key the most....maybe the = or x key (haha)
3 x 5 x 6 = 90
y= mx + b form?
3/5 x + 1/4 y = -1/2
1/4 y = -3/5 x - 1/2 Multiply both sides by '4'
y = -12/5 x - 2
or y = 2 2/5 x - 2
I will assume you mean: 4250 (.375)^5 = $ 31.52
sqrt(72) = sqrt(36 x 2) = 6 sqrt(2) = 8.485
.....and the sqrt(180) = sqrt(36 *5) = 6 sqrt(5)
A similar way:
x = 82.6939393...
10x= 826.939393....
1000x=82693.939393....
1000x 82693.9393....
- 10x 826.9393...

990x = 81867 Solve for x
x = 81867/990 = 82 687/990 = 82 229/330
13 - 4x = 1 -x add '4x' to both sides of the equation
13 = 1 + 3x Subtract 1 from each side
12 = 3x Divide by 3
4 = x
Complimentary angles add to 90 degrees.
so (3x+5) + 2x = 90 solve for 'x'
3x + 5 + 2x = 90
5x + 5 = 90
5x + 5 - 5 = 90 - 5
5x = 85
x = 17 LMN = (3x+5) = 3(17)+5 = 56 UVW = 2x = 2(17)= 34 34 + 56 = 90 Yea!
