Answer:

26, 37, 40, 48

Step-by-step explanation:

Whole numbers between 20 and 50 will have 10s digits in the range 2–5.

When 4 is added to these numbers, we get ...

2+4 = 6

3+4 = 7

4+4 = 8

5+4 = 9

When 4 is subtracted from these numbers, we get ...

2-4 = -2

3 -4 = -1

4 -4 = 0

5 -4 = 1

The numbers we can make using the given 10s digits and their corresponding 1s digit(s) are ...

26, 37, 40, 48

We note that any number with a 10s digit of 5 and a 1s digit other than 0 will be out of range.

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

shusha [124]

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 = $168\times 0.453592=76.203456$ kg

The dosage is 0.4 mg per kilogram of bod.

So, dosage of patient weight = $0.4 \times 76.2035\ mg = 30.4814\ mg$

We know, 1 micro gram = 0.001 mg

Concentration of drug is given by,

$500\ \text{micro grams/ml}= 500\times 0.001\ \text{mg/ml} = 0.5\ \text{mg/ml}$

Now we are supposed to find milliliters inject,

So, milliliters of dosage required to inject is

$d= \frac{30.4814}{0.5} = 60.9628$

Therefore, We inject 60.9628 milliliters of dosage.
