Answer:
x ≈ 229.8
Step-by-step explanation:
using the cosine ratio in the right triangle
cos72° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{LM}{KM}[/tex] = [tex]\frac{71}{x}[/tex] ( multiply both sides by x )
x × cos72° = 71 ( divide both sides by cos72° )
x = [tex]\frac{71}{cos72}[/tex] ≈ 229.8 ( to the nearest tenth )

30. The school choir is qetting ready for their spring concert. There are 48 members in the choir and each choir member expects to have ten people in the audience. How many rows of chairs will need to be set up if each row has
30 chairs in it?
Answer:
16 rows
Step-by-step explanation
48x10=480, then divide 480 by 30. 480÷30=16. So, there will be 16 rows.

The graph shows the function f(x) = |x – h| k. What is the value of h? h = –3. 5 h = –1. 5 h = 1. 5 h = 3. 5.
The function gets shifted towards the left then the value of h must be negative. The correct option is B.
What is a function?The function is an expression, rule, or law that defines the relationship between one variable to another variable. Functions are ubiquitous in mathematics and are essential for formulating physical relationships.
Given
The function is f(x) = |x – h| + k
We know that if we subtract h from the variable the function gets shifted towards the right but in the graph, the function gets shifted towards the left then the value of h must be negative.
We know the coordinate of the vertex is (-1.5, -3.5). Then abscissa will satisfy the |x - h|.
h = -1.5
Thus, option B is correct.

pls help
Answer:
the answer is 12.
Step-by-step explanation:
Hope this helps! :)
Answer:
20 ÷ [tex]\frac{5}{3}[/tex] = 12
Step-by-step explanation:
To make it a fraction form answer, you multiply the whole number by the denominator and make the result the new numerator. The old numerator becomes the new denominator:
20 x 3 divided by 5 = 60\5
Thus, the answer to 20 divided by 5/3 in fraction form is:
[tex]\frac{60}{5} = 12[/tex]

HELP NEEDED!! 30 POINTS! BRAINLY TO BEST
Answer:
18Step-by-step explanation:
By similar triangles law:-
[tex]\frac{24}{2x} =\frac{30}{x+6}[/tex]
[tex]24(x+6)=30(2x)[/tex]
[tex]24x+24(6)=60x[/tex]
[tex]24x+144=60x[/tex]
[tex]\frac{36x}{36x} =\frac{144}{36}[/tex]
[tex]x=4[/tex]
Since AB=x+6+2x
[tex]AB=3x+6[/tex]
Substitute value of x
[tex]AB=3(4)+6[/tex]
[tex]AB=12+6[/tex]
[tex]AB=18[/tex]
Therefore, the third side of ΔABC is 18.

An infinite number of non-congruent triangles can be formed with two angles, A and B. Which of the following is true about the triangles formed? None of the triangles are similar. None of the triangles are similar. Some of the triangles are similar. Some of the triangles are similar. All of the triangles are similar. All of the triangles are similar. No conclusion can be drawn without knowing the measurements of the angles.
Answer:
(c) All of the triangles are similar
Step-by-step explanation:
All of the triangles are similar by the AA similarity postulate.
__
Two angles of one triangle being the same as two angles of another triangle means all angles of the two triangles are the same. (Two angles define the third.) Triangles with congruent corresponding angles are similar.
Solve by substitution (show work pls)
y= 2x-2
-3x+4y=-23
Answer:
x = -3 y = -8 (-3,-8)
Step-by-step explanation:
first you would subsitute the y with (2x-2) in -3x+4y=-23 as y=2x-2
giving you-3x+4(2x-2)=-23
next you distribute the 4 to (2x-2) leaving you with -3x+8x-8=-23
then add -3x+8x to get 5x, having 5x-8=-23
add 8 to both sides canceling out 8 on one side and adding 8 to the other leaving you with 5x=-15 then you divide 5 from 5x to both sides leaving you with x = -3
next is y since you have x you would substitute the x in y=2x-2 with -3 getting y=2(-3)-2 then you multiply the 2 and -3 so you have y=-6-2 then you subtract those getting y = -8
Are you clever enough????
