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.
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

The objects traveled ___ meters in ____ seconds.
In problem #2 the motion of the objects starts at ___ seconds and ends at ___ seconds.
The motion of the objects starts at ___ meters and ends at ___ meters.
The objects traveled ___ meters in ____ seconds.
Step-by-step explanation:
just as the graph shows.
no trick or hidden meaning or whatever.
#1
0 seconds to 5 seconds.
0 meters to 3 meters.
traveled 3-0 = 3 meters in 5-0=5 seconds
#2
0 seconds to 8 seconds.
0 meters to 5 meters.
traveled 5-0=5 meters in 8-0=8 seconds.

Answer:
C
Step-by-step explanation:
When you cross multiply by denominator expressions that share a zero, you are effectively making that zero a solution of the resulting equation. That zero cannot be part of the domain of the original equation, and so must be an extraneous solution.
This condition is seen in choice C.
[tex]\dfrac{8}{x^2-9}=\dfrac{5}{2x-6}\qquad\text{original equation. $x\ne3$}\\\\8(2x-6)=5(x^2-9)\qquad\text{result of cross multiplying}\\\\16(x -3)=5(x+3)(x-3)\qquad\text{factored form}[/tex]
The solutions to this equation are x=1/5 and x=3. Of these, x=3 is extraneous.

A better solution method is multiplying by the least common denominator:
[tex]2(8)=5(x+3)\qquad\text{result of multiplying by $2(x^2-9)$}[/tex]

Step-by-step explanation:
lets start with 695
9 is the thousand
you check the number next to 9
less then 4 let it rest
more than 5 let it soar
something like that lol
anyways since 5 is next to the 9 we round up from 9 to the next number which is 10
so that changes the whole number to 7000

#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

Answer:
[tex]x=-\frac{5}{3}\quad \mathrm{or}\quad \:x=3[/tex]
Step-by-step explanation:
[tex]2\left|3x-2\right|=14[/tex]
⇒ Divide both sides by 2
[tex]\frac{2\left|3x-2\right|}{2}=\frac{14}{2}[/tex]
[tex]\left|3x-2\right|=7[/tex]
⇒ Now, apply absolute rule:- if |x|=a,a > a than x=a or x=-a
[tex]3x-2=-7\quad[/tex]
or...
[tex]3x-2=7[/tex]
Now,
[tex]3x-2=-7[/tex]
⇒ Add 2 to both sides:-
[tex]3x-2+2=-7+2[/tex]
[tex]3x=-5[/tex]
⇒ Divide both sides by 3:-
[tex]\frac{3x}{3}=\frac{-5}{3}[/tex]
[tex]x=-\frac{5}{3}[/tex]
[tex]3x-2=7[/tex]
⇒ Add 2 to both sides:-
[tex]3x-2+2=7+2[/tex]
[tex]3x=9[/tex]
⇒ Divide both sides by 3:-
[tex]\frac{3x}{3}=\frac{9}{3}[/tex]
[tex]x=3[/tex]
