See there is no pink
So probability of selecting a pink is 0 .
The probability of orange is 20% or 0.2
The probability of purple is 30% or 0.3
As there is no color mentioned for rest part at max probability of pink is 0.5 .
- But by now it's 0 as it's not mentioned
Answer: The potential energy decreases and the kinetic energy increases
Step-by-step explanation:
When a body is at rest , the Potential energy is maximum because the body is not moving and the acceleration is therefore zero but as soon as the body starts moving , it will convert the potential energy to kinetic energy , therefore the kinetic energy will therefore increase.
Not direct answer but
this is how I think
radius = 4 so AC is also 4
You can find with this
2π ( 4 ) ( 51°/360°) = Answer
Actually I am lazy to calculate (◔‿◔)
Answer:
If y = 2x - 5, and x = 3z, then y = 6z - 5
We know that the angles of a triangle sum to 180°. For ΔABC, this means we have:
(4x-10)+(5x+10)+(7x+20)=180
Combining like terms,
16x+20=180
Subtracting 20 from both sides:
16x=160
Dividing both sides by 16:
x=10
This means ∠A=4*10-10=40-10=30°; ∠B=5*10+10=50+10=60°; and ∠C=7*10+20=70+20=90.
For ΔA'B'C', we have
(2x+10)+(8x-20)+(10x-10)=180
Combining like terms,
20x-20=180
Adding 20 to both sides:
20x=200
Dividing both sides by 20:
x=10
This gives us ∠A'=2*10+10=20+10=30°; ∠B'=8*10-20=80-20=60°; and ∠C'=10*10-10=100-10=90°.
Since the angle are all congruent, ΔABC~ΔA'B'C' by AAA.
