Answer:
5.5
Step-by-step explanation:
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%.
<span>46 <= grade < 96
First, let's write the equation for the lower limit that the student must get for a B.
(x + 92 + 82 + 88 + 92)/5 = 80
Multiply both sides by 5 giving
x + 92 + 82 + 88 + 92 = 400
Subtract 92, 82, 88, 92 from both sides
x = 400 - 92 - 82 - 88 - 92 = 46
So the student has to get 46 or higher on the test to make a B.
Now let's compute the upper limit
(x + 92 + 82 + 88 + 92)/5 < 90
Multiply both sides by 5
(x + 92 + 82 + 88 + 92) < 450
Subtract 92, 82, 88, 92 from both sides
x < 450 - 92 - 82 - 88 - 92 ) = 96
So the student has to get a grade of less than 96 to get a B.</span>
15*12 equals 90. 2*12 is 24. Those two together equals 114. (This is an educated)
