is 12. so 12 is the length and width of the square.
To find the circumference: 12(diameter) * constant pi (3.14) = 37.68
37.68 is rounded to 37.7
the circumference of the circle is 37.7 m
1225 is a perfect square. the simplest factored form of 1225, is 35.
Answer:
x=1 ,x= -5
Step-by-step explanation:
x+2x2-4=-7x+6
2x2+x+7x-4-6=0
2x2+8x-10=0
divide through out by 2 to reduce the equation
x2+4x-5=0
by using formula method
x=[-b+\-√b2-4ac]/2a. a=1, b=4 c=-5
x=[-4+\-√4^2-4*1*-5]/2*1
x=[-4+\-√16+20]/2
x=[-4+\-√36]/2
x=[-4+\-6]/2
x=(-4+6)/2 ,x=(-4-6)/2
x=2/2 , x=-10/2
x=1 , x=-5
Answer:
1/12
Step-by-step explanation:
Let us begin by identifying all sample spaces
Sample space for coin =2
Sample space for spinner = 2
Sample space for die= 6
Total sample space S= 10
1. Probability that the coin will show tails, is = 1/2
2. Probability that the spinner will land on yellow or green, is
=1/2+1/2= 1
3. Probability that the cube will
show a three.= 1/6
Hence for this event that Fred carried out the probability is
1/2*1*1/6= 1/12
