Answer:

Diameter = 19.33

Step-by-step explanation:

Imaging a radius line from O to the endpoints of the 7. call this line R.

Label the part of the vertical line from O to the 90 degree intersection y.

Now you have a right triangle.

Using the Pythagorean theorem:

R² = 7² + y²

also

y = R - 3

substitute for y:

R² = 49 + (R-3)²

R² = 49 + R² - 6R + 9

simplify:

0 = 58 - 6R

6R = 58

R = 9.6667

Diameter = 2(9.6667) = 19.33

How many g of amino acids are in a 2,000mL total parenteral nutrition of 4.25% travesol (amino acids and 20%dextrose?

kirill115 [55]

Answer:

The mass of amino acid present is 85 g

Step-by-step explanation:

From the question we are told that

The volume of the total parenteral nutrition is $V = 2000 mL$

Generally the volume of the amino acid present is

$V_a = 0.0425 * 2000$

$V_a = 85 mL$

Generally

$mass \ \ \alpha \ \ volume$

So the mass of amino acid present is 85g
