Answer:
<em>Answer: 12 milliliters</em>
Step-by-step explanation:
<u>Proportions</u>
Each vial contains 250 milligrams of aminophylline in 10 milliliters. This means the concentration of aminophylline in the vials is 250/10 = 25 milligrams/milliliter.
To administer 300 milligrams of aminophylline, we need to find the number of milliliters according to the concentration calculated above.
If each milliliter adds up to 25 milligrams, then to have 300 milligrams, 300/25 = 12 milliliters of aminophylline vials are needed.
Answer: 12 milliliters
Answer:
Step-by-step explanation:
p=
,
(22+6)2-21=
44+12-21=
35=,
If you factor out the equation, you get that 35=4p(if you factor it out)
Therefore,
The numbers are 9 and 10.
Let x be the first number. Since they are consecutive, this means (x+1) represents the second number.
The square of x is x². The square of (x+1) is
(x+1)²=(x+1)(x+1)=x²+1x+1x+1=x²+2x+1
The difference of these squares would be given by
x²+2x+1 - x²
Setting this equal to 19,
x²+2x+1 - x² = 19
Combining like terms,
2x+1=19
Subtract 1 from each side:
2x+1-1=19-1
2x=18
Divide both sides by 2:
2x/2 = 18/2
x = 9
The first number, x, is 9. This means the second number, x+1, is 9+1=10.
