Answer:
Okay, I figured it out. XY=9.246691583 or 9.247 if you're rounding.
Step-by-step explanation:
In the right triangle of XYZ, Given that angle Z=90 degrees, angle X=58 degrees and XZ=4.9m.
Since it's a right triangle you can use SOHCAHTOA:
cosθ=adjacent/hypotenuse
cosθ=4.9/h
You can then manipulate the formula to this
h=4.9/cos(degree) = h=4.9/cos(58)
=9.246691583
hope this helps
Select the correct answer from each drop-down menu. Segment AB has seven equally spaced points on it. Starting at A and moving left to right, the points are C, D, E, F, G, H, and I. In the diagram, is divided into equal parts. The coordinates of point A are (-3, 9), and the coordinates of point B are (9, 5). The coordinates of point C are . The coordinates of point E are . The coordinates of point H are .
The coordinates of points C, E and G are respectively; C(-0.75, 8.5), E(3.75, 7.5) and H(7.5, 6)
How to find the Coordinates of a Line Segment?
We are told that the line AB is divided into 7 equally spaced points labelled as C, D, E, F, G, H and I.
Now, coordinates of A and B are; A(-3, 9) and B(9, 5)
Since they are equally spaced, then it means that point F is the midpoint of the line. If (x, y) is the coordinate of F, then;
x, y = (-3 + 9)/2, (9 + 5)/2
x, y = (6, 7)
H is the midpoint of FB. Thus;
H(x, y) = (6 + 9)/2, (5 + 7)/2
H(x, y) = (7.5, 6)
D is midpoint of A and F. Thus;
D(x, y) = (-3 + 6)/2, (9 + 7)/2
D(x, y) = (1.5, 8)
E is midpoint of F and D. Thus;
E(x, y) = (1.5 + 6)/2, (8 + 7)/2
E(x, y) = (3.75, 7.5)
C is midpoint of D and A. Thus;
C(x, y) = (-3 + 1.5)/2, (9 + 8)/2
C(x, y) = (-0.75, 8.5)

You need to make party favors for a friend's birthday. 48 people were invited, but you'll only have to make favors for those who say they will attend. Some of the favors will be yellow and the rest will be xanadu. Make a graph using paper or technology that shows all of the possible combinations of yellow or xanadu party favors you might choose to make. Let a represent the xanadu favors and y represent the yellow favors. Your graph should be labeled with x-intercept, y-intercept, shaded region, linear boundary (solid or dashed). Also include an additional point with coordinates clearly labeled in the solution region that shows me how many of each favor you choose to make after all RSVP's are received
The update of the completed graph is given in the image attached as it shows the possible combinations of Yellow or Xanadu party favors that might choose will be ( 48, 0).
What is the graph about?For this graph, we shall make Xanadu party favors as X
and yellow favors as Y
Therefore note that: X + Y = 48
In the graph of X - Intercept
Y = 0, X = 48
In the graph of Y- intercept,
Y = 48 , X = 0

Manuela has a piece of red ribbon 7 1/2 feet long. She cut the ribbon to have one piece 1 3/4 feet long.
How long is the piece of ribbon that is left?
Answer:
the leftover piece of ribbon is 5 3/4 feet long.
Step-by-step explanation:
if she has 7 1/2 feet of ribbon, and she removes (by cutting it off) 1 3/4 feet of ribbon.
So, if we set up this scenario like a math problem, we can write it as this:
7 1/2 feet of ribbon - 1 3/4 feet of ribbon = remaining ribbon
[ - = take away]
so, we are solving the equation:
7 1/2 - 1 3/4
To solve this, it is easiest to make the fractions have the same denominators
1 / 2 is equal to 2 / 4
However, 2/4 is less than 3/4, so we need to make this fraction a larger number.
To do this, we can take away 1 foot from the 7, and write it as if it were fourths
1 [foot] = 4/4 quarter foot
So, we can add 4/4 + 2/4 = 6/4
Now, we can re-write our situation.
6 6/4 - 1 3/4 = left over ribbon
6 6/4
- 1 3/4
__________
5 3/4
So, the leftover piece of ribbon is 5 3/4 feet long.

When angles form a linear pair, their sum is 180°.

Hint: First we must combine like terms. Calculate the sum
of 8x and 4x and enter the value of the coefficient.

can anyone help me ? and show solving steps if possible
Answer:
Step-by-step explanation:
Remark
They are asking you to combine like terms. The total should be 180.
Givens
2 angles
8x - 3 4x + 3Total 180
Solution
8x - 3 + 4x + 3 = 180 The threes cancel. So add what's left. They are of opposite signs, so they cancel.
12x = 180 Divide both sides by 12
12x/12 = 180 /12
x = 15
In this question we are provided with the two angles that is 8x - 3 and 4x + 3 respectively. It is also given that the sum of this two angles is 180°.
To solve this question we will combine the like terms and there sum must be 180°.

Explain how the modern double-slit experiment showed different results than Young’s double-slit experiment.
Modern:
Where there are two open slits, the resulting pattern will simply be the sum of the two single-slit patterns (two vertical lines). But again and again, the experiment demonstrated that the coherent beams of light were interfering, creating a pattern of bright and dark bands on the screen.
Young's
In the end, the double slit experiment discovered that electrons, and all quantum particles, both exist as particles and probability waves. Quantum particles existing as probability waves means that we don't know for certain where these particles are, we can only know the probability of where they will be.
Given line PQ bisects line RS, LR=LS
Prove: Triangle PQR= Triangle PQS
Answer:
See Below
Step-by-step explanation:
Since PQ is perpendicular to RS, the angles PQR and PQS would be right angles, and right anglers are congruent, so <PQR ≅ <PQS. We are given that <R and <S are the same length, so they are congruent(<R ≅ <S). Since PQ is included in both triangles and it is the same length as itself(PQ ≅ PQ).
We have three congruent parts, two angles and one side. Therefore, using AAS, ΔPQR ≅ ΔPQS
Answer:
See below ~
Step-by-step explanation:
Given :
⇒ PQ ⊥ RS
⇒ ∠R = ∠S
===============================================================
Solving :
⇒ PQ = PQ (common side)
⇒ ∠R = ∠S (given)
⇒ ∠PQS = ∠PQR = 90° (⊥ bisector forms equal right angles)
⇒ ΔPQR ≅ ΔPQS (by ASA congruence)
