Point 2 = (4, −7)
Required Information:
Distance between points = d = ?
Answer:
Distance between points = d = √32 = 5.657
Step-by-step explanation:
We are given two points,
(x₁, y₁) = (8, −3)
(x₂, y₂) = (4, −7)
We are asked to find the distance between these two points.
The distance is given by
Substitute the given coordinates into above equation
Therefore, the distance between (8, −3) and (4, −7) is 5.657 units.
Answer: Three quarters (30 ml) is made up of a 36% acid solution.
Step-by-step explanation:
Since we have given that
Total amount of solution = 40 ml
One- quarter of the solution is given by
Three-quarter of the solution is given by
According to question, we have
10 ml of solution is made up of = 20% of acid solution
30 ml of solution is made up of = say<em> 'c </em>' of acid solution
40 ml of solution is made up of = 32 % of acid solution
So, our equation becomes,
Hence, three quarters (30 ml) is made up of a 36% acid solution.
