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.

A school has an equal amount of boys and girls. You use a coin to simulate the first three students to arrive at school each day

Nimfa-mama [501]

Answer:3/20

A certain television is advertised as a 26 inch TV (the diagonal length). If the width of the TV is 10 inches, how many inches t

emmainna [20.7K]

Answer: The TV is 24 inches tall

Step-by-step explanation: The question has provided the diagonal and the width of the rectangle shaped television. From this bit of information, we can deduce that the diagonal of the rectangle (television) is also the Hypotenuse (26 inches) while the the other two sides are the Length and the Width (10 inches).

For every right angled triangle, we can apply the Pythagoras theorem to solve for any unknown side. The theorem states that

AC² = BC² + AB²

Where AC is the hypotenuse (longest side)

26² = 10² + AB²

676 = 100 + AB²

Subtract 100 from both sides of the equation

576 = AB²

Add the square root sign to both sides of the equation

√576 = √AB²

24 = AB

Therefore, the height of the television is 24 inches

**WILL MARK BRAINLIEST AND THANK YOU**

omeli [17]

A is correct because f(1)=3^1+1 so f(1)=4 and g(x)=4 so f(x)=g(x)

B is also correct because the ordered pair we get is (1,4) and this is in quadrant 1

C is incorrect

D is incorrect

E is incorrect

Ans: A and B are correct
