Digoxin (lanoxin) is available for parenteral pediatric use in a concentration of 0.1 mg/ml. how many milliliters would provide a dose of 40 μg?

0.4mL would provide a dose of 40 μg.

Step-by-step explanation:

The problem states that the Digoxin (Lanoxin) is available for parenteral pediatric use in a concentration of 0.1 mg/mL. And asks how many milliliters would provide a dose of 40 μg?

The first step is the conversion of 0.1mg to ug.

Each mg has 1000 ug, so:

1mg - 1000ug

0.1mg - xug

x = 1000*0.1

x = 100ug

So the concentration of the Digoxin that is available for parenteral pediatric use is 100ug/mL. How many mL would provide a dose of 40ug.

As the number of mL increases, so does the size of the dose(ug). It means that there is a direct relationship between the measures, and we have a direct(cross multiplication) rule of three. So

1mL - 100ug

xmL - 40ug

100x = 40

x = 0.4mL

0.4mL would provide a dose of 40 μg.

step-by-step explanation:

let's assume

number of candles set =x

price of of x candles =p(x)

we are given

a candle maker prices one set of scented candles at $10 and sells an average of 200 sets each week

so, we get point as (200,10)

he finds that when he reduces the price by $1, he then sells 50 more candle sets each week

so, we can find slope

now, we can use point slope form of line

now, we can plug values

we can use point

and find b

now, we can plug it back

and we get

now, we can find revenue

we know that

revenue = price*quantity

so, we get
