Answer:
The percentage (V/V) of liquid menthol in the ointment is 1.59%.
Step-by-step explanation:
Given : A prescription for an ointment has 3.5 mL of liquid menthol in a total of 220 mL.
To find : Calculate the percentage (V/V) of liquid menthol in the ointment ?
Solution :
Volume of liquid menthol is 
Total volume of ointment is 
The V/V percentage is given by,
Therefore, the percentage (V/V) of liquid menthol in the ointment is 1.59%.
Y and z will help find the answer for the measurement to x (Pythagorean theorem
Answer:
y = 15
Step-by-step explanation:
As QR parallel to TS
QR = TS
11 = y - 4
y = 11 + 4
y = 15
Answer:
The coefficient of variable term y is -1
Step-by-step explanation:
We have an expression given in the question that is:
6 - y + 3
We have to find the coefficient of the variable term.
In mathematics, variable can be defined as any term which is to be measured. For example in the given expression, y is the variable because its value is unknown yet and it has to be measured.
Coefficients are the number the multiply the variable
For example
In 2x, x is the variable and 2 is the coefficient.
Now in the given expression, we have
6 - y + 3
or
6 + (-1)(y) + 3
So considering (-1)(y), the variable is y while its coefficent is -1
