An emergency room doctor prescribes a certain pain medication to be delivered through an IV drip. She prescribes 800 mL of the
Keith_Richards [23]

Answer:

The number of drips per minute needed to deliver the medication at the prescribed dosage is 50 drips per minute

Step-by-step explanation:

The given parameters are;

The volume of the prescribed medication to delivered through IV = 800 mL

The duration over which the drug is to be delivered = 8 hours

The rate at which the IV delivers the medication = 30 drips/1 mL

800 mL = 800 × 1 mL

Therefore, the total number of drips in 800 mL= 800 mL × 30 drips/mL = 24,000 drips

The rate at which the drug is delivered = 800 mL/(8 hours) = 100 mL/hr = 100/60 mL/minute = 10/6 mL/minute

The total number of drips in 10/6 mL= 10/6 mL × 30 drips/mL = 50 drips

∴ The rate at which the medication needs to be delivered = 10/6 mL/minute = 50 drips/minute

The number of drips per minute needed to deliver the medication at the prescribed dosage of 800 mL/(8 hours) = 10/6 mL/minute = 50 drips per minute.

Find the area of the composite figure. Round to the nearest tenth.
mihalych1998 [28]

Answer:

Surface area of figure = 200.52 meter²

Step-by-step explanation:

Given:

Side of square cut = 12 meter

Diameter of semi circle = 12 meter

Find:

Surface area of figure

Computation:

Diameter of semi circle = 12 meter

Radius of semi circle = Diameter of semi circle / 2

Radius of semi circle = 12 / 2

Radius of semi circle = 6 meter

Surface area of figure = Surface area of square + Surface of cylinder

Surface area of figure = [Side x Side] + πr²/2

Surface area of figure = [12 x 12] + (3.14)(6)²/2

Surface area of figure = [144] + (3.14)(36)/2

Surface area of figure = 144 + 56.52

Surface area of figure = 200.52 meter²
