The 12 m of fencing s equal to the circumference of the circle.

If the radius is r, then the circumference is
2πr = 12
r = 12/(2π) = 6/π = 1.91 m

Answer: r = 6/π m or 1.91 m (nearest hundredth)

Which polynomial is a difference of two squares? O x² – 16 O x² +16 O x² – 8 O x² + 8​
UNO [17]

Answer:

x²-16

Step-by-step explanation:

x²-16 =0

Add 16 to both sides

x²-16 + 16 = 0 + 16

Simplify

x²= 16

For x²=(fa) the solutions are x = √(fa), -√(fa)

X=√16 ,X= -√16

√16=4

-√16 = -4

x=4, x= -4

A bag holds 12 red marbles, 11 green marbles, 17 blue marbles, and 5 yellow marbles. What is the probability that you will NOT c
Oduvanchick [21]

Answer:

Step-by-step explanation:

No of sample space , n(s) = 12 + 11 + 17 + 5 = 45

No of favorable cases , n(e) = 17

Probability of getting blue marble ,

P(e) = n(e)/n(s)

        = 17 / 45

NOW

Probability of not getting blue marble,

P'(e) = 1 - p(e)

       = 1 - 17 / 45

      = ( 45 - 17)/45

     = 28 / 45

Hope it helped :)
