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

Terbium-160 has a half-life of about 72 days.
Nastasia [14]
For the half-life of a certain substance, the equation that would best represent the scenario is,
                             At = Ao(0.5^t/n)
where At is the amount at any time t, Ao is the original amount, and n is half-life. Substituting the known values,
                            At = (220 mg)(0.5^(396/72)
                            At = 4.86 mg
Thus, after 396 days, there will only be 4.86 mg of Terbium-160.

Help please! 10 points!
NISA [10]

Let's assume

number of chairs =x

number of tables =y

we are given

Gavin builds furniture for a living. he Sells chairs for $45 and tables for $70 each

So, we can find objective function as

Z=45x+70y

now, we can find inequalities

A table requires 10 hours and $15 worth of supplies to make

so, total hours to make table =10y

amount spent on table =15y

It takes Gavin 4 hours and $10 worth of supplies to build each chair

so, total hours to make chair =4x

amount spent on chair =10x

total number of hours to make chair and table =4x+10y

Gavin wants to work for no more than 40 hours per week

so, we get

4x+10y\leq 40

spend no more than $80 on materials

so, we get

10x+15y\leq 80

so,

objective function:

Z=45x+70y

Constraints:

4x+10y\leq 40

10x+15y\leq 80
