The sum of two numbers is 25. One of he numbers exceeds the other by 9. Find the numbers
Vitek1552 [10]
X + y = 25
x is the smaller number.
y is the smaller number plus 9 (x + 9).

x + (x + 9) = 25
2x + 9 = 25
2x = 16
x = 8

8 + y = 25
y = 17

The numbers are 8 and 17.

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
kipiarov [429]

Answer:

You inject 60.9628 milliliters of dosage

Step-by-step explanation:

1 pound = 0.453592kg,

Patient's weight in pounds = 168

Patient's weight in kg = 76.2035  kg

Now we are given that The dosage is 0.4 mg per kilogram of bod

So, dosage = 0.4 \times 76.2035 mg = 30.4814 mg

1 microgram = 0.001 mg

Concentration of drug = 500 micrograms/ml = 500 * 0.001 mg/ml = 0.5 mg/ml

Now we are supposed to find How many milliliters (= cc) are you to inject?

So,milliliters of dosage required to inject = \frac{30.4814}{0.5} = 60.9628

Hence you inject 60.9628 milliliters of dosage
