Given: mAngleORP = 80° mAngleORN = (3x + 10)° Prove: x = 30 3 lines are shown. A line with points P, R, N intersects a line with

points M, R, O at point O. A line extends from point R to point L between angle M R P. Angle N R O is (3 x + 10) degrees and angle P R O is 80 degrees. Which statement could be used in step 2 when proving x = 30? A 2-column table with 5 rows. Column 1 is labeled statements with the entries measure of angle O R P = 80 degrees semicolon measure of angle O R N = (3 x + 10) degrees, blank, blank, blank, blank. Column 2 is labeled reasons with the entries given, blank, blank, blank, blank. AngleORP and AngleORN are a linear pair AngleORP and AngleORN are vertical angles 80 = 3x +10 x = 30

Answer:

  Angle ORP and Angle ORN are a linear pair

Step-by-step explanation:

The proof will entail making use of the fact that ∠ORP and ∠ORN are supplementary. Whether their description as a linear pair is a statement or a reason will depend on your approach to the proof. Apparently, here, you are calling this fact a "statement".

The second (and subsequent) line(s) of the table might be ...

2 (statement) ORP and ORN are a linear pair. (reason) OR is a common side and R is a common vertex on line PN for these angles, hence they meet the definition of a linear pair.

3 (statement) ORP and ORN are supplementary. (reason) definition of a linear pair

4 (statement) 80 + (3x+10) = 180. (reason) substitution property; supplementary angles sum to 180 degrees

5 (statement) 3x = 90. (reason) subtraction property of equality

6 (statement) x=30. (reason) division property of equality

What is permutation and combination?

A set of elements can be divided into subsets in two different ways: combination and permutation.

                          The components of the subset may be arranged in any order when combined. The components of the subset are listed in a permutation in a certain order.

If the word has 5 different letters  then it is just 26-choose-5 or (26/5).

If the word has 4 different letters  then it is just 26-choose-4 or (26/4)

have 4 options to choose which letter to duplicate twice.

This gives =  4*(26/4)

If the word has 3 different letters  then it is just 26-choose-3 or (26/3).

you duplicate one of the three letters 3 times - 3 options for that, or you choose 2 letters and duplicate each one twice - again 3 options. In total this gives  = 6*(26/3).

If the word has 2 different letters  then it is just 26-choose-2 or (26/2).

The sets of 2 different letters and duplicate either one of the letters 4 times - 2 options; or duplicate one letter 2 times, and the other 3 times - again 2 options. In total this is  = 4*(26/2).

The word has just 1 distinct letter you have =  (26/1).

we get :

N = (26/5)+ 4*(26/4) + 6*(26/3) + 4*(26/2) +  (26/1)

= 142506

2. A lunch stand makes s.75 profit on each chef's salad and $1.20 profit on each Caesar salad. On a typical weekday, it sells be
kow [346]

Let's let

<u>x = the number of chef salads, x>=0</u>

<u>y = the number of Caesar salads, y>=0</u>

The constrains are:

40 <= x <= 60

35 <= y <= 50

x + y <= 100

The objective function here is F(x, y) = 0.75x + 1.20y

The corner points are (40, 35),  (60, 35), (60, 40), (50, 50) and (40, 50).

F (40, 35) = 0.75*40 + 1.20*35 = $72

F (60, 35) = 0.70*60 + 1.20*35 = $84

F (60, 40) = 0.75*60 + 1.20*40 = $93

F (50, 50) = 0.75*50 + 1.20*50 = $97.50

F (40, 50) = 0.75*40 + 1.20*50 = $90

Thus, we conclude to maximize the profit 50 Chef and 50 Caesar salads should be prepared.

when a relation is drawn on an xy-plane what is another name for the set of all x values from its graph?
Galina-37 [17]

Another name for the set of all x-values for a relation is: domain.

<h3>What is the Domain of a Relation?</h3>

The domain of a relation can be defined as all the x-values that corresponds to the y-values that are plotted on a graph.

They are referred to as the input or the domain of the relation. Therefore, another name for the set of all x-values plotted for a relation on a graph is: domain.
