Answer:

Option A: Elena can work as a server for 5 hours and edit poetry for 10 hours.

Explanation:

We are given the system of linear inequalities modeling this situation as; 10.50x + 8.50y ≥ 125

x + y ≤ 17

Where;

x represents number of server working hours per week.

y represents number of editing poetry hours per week.

In option A, x = 5 and y = 10. Let's plug them both into the first equation;

10.50(5) + 8.50(10) ≥ 125

Left hand side gives 137.5. So it fulfills the inequality.

Repeating the same for the 2nd equation, we have;

5 + 10 ≤ 17

Left hand side is 15 and it fulfills the equation. Option A is correct.

In option B, x = 10 and y = 9. Let's plug them both into the first equation;

10.50(10) + 8.50(9) ≥ 125

Left hand side gives 181.5. So it fulfills the inequality.

Repeating the same for the 2nd equation, we have;

10 + 9 ≤ 17

Left hand side is 17 and it doesn't fulfill the inequality. Option B is wrong.

In option C, x = 10 and y = 1. Let's plug them both into the first equation;

10.50(10) + 8.50(1) ≥ 125

Left hand side gives 113.5. So it doesn't fulfill the inequality.

Option C is wrong.

In option D, x = 3 and y = 10. Let's plug them both into the first equation;

10.50(3) + 8.50(10) ≥ 125

Left hand side gives 116.5. So it doesn't fulfill the inequality.

Option D is wrong.

<span>A: put an atom on a poster in the exhibit
     Good luck.  The poster itself is made of trillions of trillions of trillions
     of atoms.  You could not see the extra one any easier than you could
     see the ones that are already there, and even if you could, it would be
     lost in the crowd.
 
B: use a life size drawing of an atom
     Good luck.  Nobody has ever seen an atom.  Atoms are too small
     to see.  That's a big part of the reason that nobody knew they exist
     until less than 200 years ago.

D: set up a microscope so that visitors can view atoms
     Good luck.  Atoms are way too small to see with a microscope.

</span><span><span>C: Display a large three dimensional model of an atom.
    </span> </span>Finally !  A suggestion that makes sense.
     If something is too big or too small to see, show a model of it
         that's just the right size to see.

A cylindrical blood vessel is partially blocked by the buildup of plaque. At one point, the plaque decreases the diameter of the
densk [106]

Answer:10.4 times of initial velocity

Explanation:

Given

Diameter reduced by 69 %

it approaches with velocity v_0

suppose its velocity is v during blocked passage

suppose d is the initial diameter and d_2 diameter is

d_2=d(1-0.69)

d_2=0.31 d

A_2=\frac{\pi d_2^2}{4}

As flow is constant

Q_1=Q_2

d^2v_0=d_2^2v

v=10.40 v_0

Ludmilka [50]

Answer:

The Production Function is the relationship between the quantity or variables of output and the different inputs quantities used in the production process.

Explanation:

Generally in quality, production or any business, we need to know what is the output with respect to different input variables. Suppose if an output is about bottle produce per hour, then we look at the inputs such as temperature, raw material/inventory, power supply, manpower, etc which are needed to produce bottle. any changes, for example in temperature could change the production rate.

Furthermore, a graph is made to see the production function.
