Answer:

about 13.73 square feet

Step-by-step explanation:

We presume you want the area of the figure.

It can be decomposed into a triangle with base 3.6 ft and height 4.8 ft, together with a semicircle of diameter 3.6 ft.

The area of the triangle is given by ...

A = 1/2bh

For the given base and height, this is ...

A = (1/2)(3.6 ft)(4.8 ft) = 8.64 ft²

The radius is half the diameter, so the radius of the semicircle is 1.8 ft. The area of a whole circle of radius 1.8 ft is given by ...

A = πr² = π(1.8 ft)² = 3.24π ft²

We want the area of half the circle, so its area will be ...

semicircle area = (1/2)(3.24π ft²) = 1.62π ft² ≈ 5.089 ft²

Then the total area of the figure is ...

total area = triangle area + semicircle area

= 8.64 ft² + 5.09 ft²

total area = 13.73 ft²

A patient is ordered 60 mg/kg/day of an antibiotic to be divided in 3 doses per day. The patient weighs 60 kg. How many mg of dr

Fudgin [204]

Answer:

3600 mg of drug per day.

$\text{The amount of drug per dosage}=\text{1200 mg}$

Step-by-step explanation:

We have been given that a patient is ordered 60 mg/kg/day of an antibiotic.

Since the weight of the patient is 60 kg, so the dosage of drug per day would be 60 mg times 60.

$\text{The dosage of drug per day}=\frac{\text{60 mg}}{\text{ kg}}\times 60\text{ kg}$

$\text{The dosage of drug per day}=\text{60 mg}\times 60$

$\text{The dosage of drug per day}=\text{3600 mg}$

Therefore, the patient should receive 3600 mg of drug per day.

Since the patient gets 3 doses per day, so dosage of drug per dosage would be amount of drug per day divided by 3.

$\text{The amount of drug per dosage}=\frac{\text{3600 mg}}{3}$

$\text{The amount of drug per dosage}=\text{1200 mg}$

Therefore, the amount of drug per dosage would be 1200 mg.

U-8.1 = 6.35 what does u=

Nesterboy [21]

Since U is being subtracted by 8.1, we can assume that if we added 8.1 to both sides, it should equal U

U - 8.1 = 6.35 To make it equal to U, we have to add 8.1 to both sides

The answer is,

U = 14.45
