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

A roof in the shape of a half-cylinder covers the a local soccer field so kids can play soccer

leonid [27]

Answer:

6,280 ft³

Step-by-step explanation:

To find lateral surface area, use the formula L = 2 $\pi$ rh, then plug in the values:

L = 2(3.14)(25)(80)

L = 12,560 ft³

Since its a half cylinder, we have to divide this by 2:

12,560/2 = 6,280

So, the lateral area of the roof is 6,280 ft³
