850/550= 1.7
it will take 1.7 hours or 1 hour and 42 minutes
add this to 11:30 AM
11:30+01:42= 1:12
then subtract the hour
13:12-1:00= 12:12

so it will be 12:12 when the plane lands in chicago

You time someone completing a single task the first time at 100 minutes and the fourth time they do the task it takes 81 minutes
kolezko [41]

Answer:

given statement is false

Step-by-step explanation:

given data

first time = 100 minutes

fourth time  = 81 minutes

solution

as here time for 1st unit is multiply by learning percentage for obtain time for 2nd unit

so here time for 2nd unit divide by time of 1st unit so 100 is here learning curve

so \frac{81}{100} × 100 = 81 percent

but it say 90 percent learning curve

so given statement is false

Lidocaine (2 grams) was prescribed in 500 mL of fluid at 2 mg/ minute, to be administered via an infusion pump. What is the flow
Luden [163]

9514 1404 393

Answer:

  1/2 mL/min

Step-by-step explanation:

  \dfrac{2\text{ mg}}{\text{min}}\div\left(\dfrac{2\text{ g}}{500\text{ mL}}\times\dfrac{1000\text{ mg}}{\text{g}}\right)=\dfrac{2\times500\text{ mL}}{2\times1000\text{ min}}=\boxed{\dfrac{1}{2}\text{ mL/min}}

__

<em>Additional comment</em>

The units analysis tells you how to work this problem. In order to get from mg/min to mL/min, you need to multiply by a factor with units mL/mg. Those units are the inverse of the concentration in mg/mL, which is found from g/mL.
