Answer:
5.89 mL
Step-by-step explanation:
doctor prescribed = 0.75 ml (2x a day) = 1.5 mL
pharmacist labeled = 3/4 teaspoon (0.75 teaspoon (2x a day) = 1.5 teaspoon
convert 1.5 teaspoon to mL = 7.39 mL
therefore,
the excess medication given in one day = 7.39 mL - 1.5 mL = 5.89 mL
Ok, so first this is a system. You have:
8x+12y=3200
And
X+y=300.
That means y= -X + 300.
If you replace "y" in the first equation with -X+300, it would be 8x+12(-X+300)=3200.
If you simplify that, X will be equal to 100. Now go back to the second equation, which is X+y= 300.
Now that you know X is 100, you can subtract it from 300 to find y.
So,
X=100 and y=200!
Hope this helps!!!
A simple way to get the dimensions is just to rearrange the equation.
<span>So in a.) (i'm going to assume t2 is t squared) </span>
<span>rearrange: </span>
<span>x = Bt2 ----> B= x/t2 </span>
<span>Now you are told that x is displacement (L) and t is time (T) so sub these in. </span>
<span>B= L/T2 Therefore the dimensions are L/T2. </span>
<span>In b.) following the same steps: </span>
<span>x = A sin(2πft) ----> A = x/sin(2πft) </span>
<span>The hint tells you that sin(2πft) is dimensionless so you can disregard that part. </span>
<span>A = x </span>
<span>A=L</span>
