Answer:

15%  

Step-by-step explanation:

$40 : 100 = 0,4

1% is $0,4

$6 : 0,4 = 15%

So the percentage is 15%.

Find the minimum value of the function for the polygonal convex set determined by the given system of inequalities.
lutik1710 [3]

Answer:

Option b (4,1)

Step-by-step explanation:

The region given by the system of inequalities is shown in the graph. We must look within this region for the point that minimizes the objective function f(x, y) = 8x + 8y

The minimum points are found in the lower vertices of the region.

These vertices are found by equating the equations of the lines::

3x+2y=14\\-5x +5y=10

-------------------

x = 2\\y = 4

-8x + 3y = -29\\3x + 2y = 14

---------------------

x = 4\\y = 1

The lower vertices are:

(4, 1) (2, 4)

Now we substitute both points in the objective function to see which of them we get the lowest value of f(x, y)

f(4, 1) = 8(4) +8(1) = 40\\f(2, 4) = 8(2) + 8(4) = 48

Then the value that minimizes f(x, y) is (4,1).

Option b

What additional information would be needed to prove that the triangles are congruent using the ASA congruence theorem? ON ≅ MN
dybincka [34]

Answer:

ΔLNO ≅ ΔLMN iff ∠LNO = ∠LNM

Step-by-step explanation:

Lets get started using the statement that...

<em> In ΔLON and ΔLMN</em>

 <u><em> Side ON ≅ Side MN </em></u>

<u><em>   Side LN ≅ Side  NM </em></u>

<u><em>     ∠LON ≅ ∠LMN</em></u>

To Prove: ∠LON ≅ ∠LMN by ASA congruence theorem.

Solution:  In order to prove ASA congruence between the triangles we need two angles to be congruent to each other. When we look at the figure, we see that <u><em>∠LNO ≅ ∠LNM is a common angle </em></u>in both the triangles.

Hence, using this we will prove that the triangles are congruent by ASA congruence rule.

<u><em>In ΔLON and ΔLMN</em></u>

 Side ON ≅ Side MN

 ∠LNO ≅ ∠LNM ( ∵ common )

 ∠LON ≅ ∠LMN (∵ Given )

<u>⇒ ΔLON ≅ ΔLMN ( By ASA congruence theorem).</u>
