Answer:
The percentage of drug in the resultant solution is 25% .
Step-by-step explanation:
Given :A pharmacist added 50 g of drug to make a total of 200 mL of solution.
To Find : What is the percentage of drug in the resultant solution?
Solution:
Amount of drug = 50 g
Amount of solution = 200 ml
So, the percentage of drug in the resultant solution = 
= 
= 
Hence The percentage of drug in the resultant solution is 25% .
Answer:
The line parallel to this one and going through said point is y = 3x - 9
Step-by-step explanation:
In order to find this, we start by noting that the slope will be 3 because parallel lines have the same slope. Now we can use point-slope form to find the equation of the line.
y - y1 = m(x - x1)
y - 0 = 3(x - 3)
y = 3x - 9
Answer the answer is a 15.81
Step-by-step explanation:
There are 24 hours in a day so it would be 21 x 24 which is
504 so your answer is The Turtle can walk 504 miles a day at a rate of 21m/hr.
Answer:
The measure of angle N is 141°.
Step-by-step explanation:
From the given figure it is noticed that the angle 39° and angle N lies on a straight line. It means both angles are supplementary angles.
If two angles are known as supplementary angles, then their sum is 180°.
Since angle 39° and angle N are supplementary angle, therefore their sum is 180°.
Subtract 39 from both sides.
Therefore the measure of angle N is 141°.
