Answer:
40 drops
Approximately 0.166 %
Step-by-step explanation:
It would be easier to work the same units for volume
Since there are 1000 ml in a liter
Original water volume 1.2 L = 1.2 x 1000 = 1200 mLl
The final volume of the acid-water solution = 1.202 L = 1202 mL
So total volume of acid added = 1202-1200 = 2 mL
Each drop of acid is 0.05 mL
Number of drops added = 2/.05 = 40 drops
Percent of acid in acid solution = (Volume of acid added)/(Final volume) x 100 = (2/1202) ≈ 0.00166 x 100 ≈ 0.166 %
Hey there!!
How do we find slopes ?
Slope = 
We are given with two co-ordinates :
(-1,8) and (3,-4)
Hence, the slope is :
... 
= -3
The slope is -3.
Hope my answer helps!
Answer:
please mark me brainliesf if it helps you
f(x) = -3x+1
or, y = -3x + 1
Interchanging the position of x and y, we get,
x = -3y +1
or, 3y = 1 - x
or, y = 1 - x /3
: . f^-1(x) = 1-x / 3
The answer is undefined
The slope of a line can be positive, negative, zero, or undefined. A horizontal line has slope zero since it does not rise vertically (i.e. y1 − y2 = 0), while a vertical line has undefined slope since it does not run horizontally (i.e. x1 − x2 = 0).
Answer:
6 +67 _^76 + 9 x 2087 - 9012 = 1000
Step-by-step explanation:
98 + 2000 - 76 = 1000
