Answer:
Step-by-step explanation:
To calculate the distance (d) use the distance formula
d = √ (x₂ - x₁ )² + ( y₂ - y₁ )²
with (x₁, y₁ ) = (- 1, 4) and (x₂, y₂ ) = (6, - 2)
d =
=
= = ← exact distance

explanation : just write it in fraction form
Answer:
There are 65,7 ml of acid.
Step-by-step explanation:
This is a percent problem. When we have a total (in this case 371 ml of a solution), it's value is the 100%. As only 17,7% is only the part we are interested in (acid), we shall get a cross-multiplication like this one:
371 ml ----------- 100%
x= ------------17.7%
This must be resolved multiplying 17.7 x 371 and dividing the result by 100.
This number rounded to the nearest tenth is 65,7.
