Answer:
Step-by-step explanation:
The sum of N consecutive natural numbers is given by:
We need to find the sum of the natural numbers between 12 to 38.
To calculate the required sum we have F=12, L=38, but we don't have the value of N.
From 12 to 38 there are 38 - 12 + 1 = 27 natural consecutive numbers, thus N=27.
Substituting in the formula:
Answer:
We inject 60.9628 milliliters of dosage.
Step-by-step explanation:
Given : You are to give an injection of a drug. The dosage is 0.4 mg per kilogram of bod The concentration of the drug in vial is listed as 500 ug/ml. The patient's chart Hosts weight as 168 pounds.
To find : How many milliliters (= cc) are you to inject?
Solution :
We know that,
1 pound = 0.453592 kg,
Patient's weight = 168 pounds
Patient's weight in kg = kg
The dosage is 0.4 mg per kilogram of bod.
So, dosage of patient weight =
We know, 1 micro gram = 0.001 mg
Concentration of drug is given by,
Now we are supposed to find milliliters inject,
So, milliliters of dosage required to inject is
Therefore, We inject 60.9628 milliliters of dosage.
