Triangle WXY is dilated by a scale factor of 3/4 to form triangle W'X'Y'. Side Y'W' measures 34.5 What is the measure of side YW?
When a shape is dilated, the size of the resulting shape will either be bigger or smaller than the original shape.
The measure of side YW is 46
Given that:
[tex]k = \frac 34[/tex] ---- scale of dilation from [tex]\triangle WXY[/tex] to [tex]\triangle W'X'Y'[/tex]
[tex]Y'W' = 34.5[/tex]
This means that:
Side lengths of [tex]\triangle W'X'Y[/tex] = Side lengths of [tex]\triangle WXY \times k[/tex]
So, we have:
[tex]Y'W' = YW \times k[/tex]
Substitute known values
[tex]34.5 = YW \times \frac 34[/tex]
[tex]34.5 = YW \times 0.75[/tex]
Divide both sides by 0.75
[tex]46 = YW[/tex]
Rewrite as:
[tex]YW =46[/tex]
Hence, the measure of side YW is 46

If 5 tennis balls are put into 4 boxes, use the Pigeonhole principle to show that at least one box will contain 2 tennis balls
Answer:
If 5 tennis balls are put into 4 boxes, with 5 tennis balls > 4 boxes, then at least one box will contain more than 1 tennis ball.
Step-by-step explanation:
Answer:
Step-by-step explanation:
Well one of the first things you could do is put all 5 into one box. That means that that box contains at least 2 tennis balls.
Next being given to experiment, you put 2 balls in 1 box and 3 in another and the condition of 1 box containing at least 2 balls is still met.
So you do the best thing you can. You take 4 balls and put one in each box. So far you have not met the condition of the problem.
But you have one ball in your hand. Wherever you put the tennis ball, it must be in one of the boxes. That will meet the condition of the problem. One box has to have 2 balls in it.

#3 Q is the midpoint of PR, PQ = 2x, and PR = 8x - 12. Find X, PQ, and PR.
(x - 12 = 2x
2x = 8x 12+ 8x - 12
(Number 3!!!!)
Answer:
x = 3, PQ = 6 , PR = 12
Step-by-step explanation:
Given Q is the midpoint of PR , then
PQ = QR = 2x
PR = PQ + QR , that is
8x - 12 = 2x + 2x
8x - 12 = 4x ( subtract 4x from both sides )
4x - 12 = 0 ( add 12 to both sides )
4x = 12 ( divide both sides by 4 )
x = 3
Then
PQ = 2x = 2 × 3 = 6
PR = 8x - 12 = 8(3) - 12 = 24 - 12 = 12

9x-2y=2
Step by step needed asap
Answer:
(0,-1) I could be wrong
Step-by-step explanation:
Answer:
Step-by-step explanation:
-2x+9y=-9 (solve for x)
-2x= -9y-9
X = - 9y/-2 - - 9/2. X = 9y/2 + 9/2
9(9/2y+9/2)-2y=2
81y/2 + 81/2 - 2y = 2
81y/2 - 2y = 2 - 81/2. 81/2 - 2 = 77/2 and -81/2 +2 = -77/2
77/2 y = - 77/2
y = (-77/2)/(77/2)
y = - 1

AC = 8, AB = 2x + 20, and BC = 2x + 24. Find x.
Answer:
Answer: x is -9
Step-by-step explanation:
If it's a line AC with a point B between;
AC = AB + BC
substitute in terms of x :
[tex]8 = (2x + 20) + (2x + 24)[/tex]
group x terms in a same bracket, and constants in their bracket
[tex]8 = (2x + 2x) + (20 + 24) [/tex]
operate the brackets:
[tex]8 = 4x + 44[/tex]
subtract 44 from both sides:
[tex]8 - 44 = (4x + 44) - 44 [/tex]
simplify:
[tex] - 36 = 4x[/tex]
divide all sides by 4:
[tex] \frac{ - 36}{4} = \frac{4x}{4} \\ \\ x = - 9[/tex]
