A carton has a length of fraction 2 and 1 over 6 feet, width of fraction 1 and 1 over 5 feet, and height of fraction 2 and 1 ove

ozzi

Answer:

6 1/2 cubic feet

Step-by-step explanation:

A carton has a length of 2 1/6 feet

The width is 1 1/5 feet

The height is 2 1/2 feet

Therefore the volume of the carton can be calculated as follows

= length × width × height

= 2 1/6 × 1 1/5 × 2 1/2

= 13/6 × 6/5 × 5/2

= 390/60

= 13/2

= 6 1/2 cubic feet

Hence the volume of the carton is 6 1/2 cubic feet

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

Its 1/5,

35/100 - 15/100 = 20/100

for 20, 40, 60, 80, 100
1, 2, 3, 4, 5

Answer:

Step-by-step explanation:

Note: Take note , absolute value will give the magnitude of the value. (Which means ignoring the + / - signs.)

Eg. | - 19 | = 19

Therefore,

$\frac{12(30 - (9 + {4}^{2})) }{10 - | - 6| } \\ = \frac{12(30 - (9 + 16))}{10 - 6} \\ = \frac{12(30 - 25)}{4} \\ = \frac{12(5)}{4} \\ = \frac{60}{4} \\ = 15$
