31 degrees (vertically opposite angle)
Answer:

Step-by-step explanation:
Let the number be x
Subtract 1/2 from x = (x - 1/2)
Multiply 1/2 to the result = 1/2(x - 1/2)
The result is 1/8
That is,

Answer:
(x + 3, y - 2)
Step-by-step explanation:
we know that
The rule of the transformation T is equal to
T: pre-image → image
T: (x, y) → (x',y')
T: (x, y) → (x - 3, y + 2)
so
x'=x-3 ----> x=x'+3
y'=y+2 ----> y=y'-2
The rule of the inverse of transformation T -1 is equal to
T-1: image → pre-image
T-1: (x', y') → (x,y)
T-1: (x', y') → (x'+3, y'-2)
Answer:
P = 15.71 cm
Step-by-step explanation:
Given that,
The diameter of the semicircle, d = 10 cm
Radius, r = 5 cm
The perimeter of the semicircle is given by :

So, the perimeter of the semicircle is 15.71 cm.
Answer:
.943686485
Step-by-step explanation:
1=p(0)+p(1)+p(2)+p(3)+.....p(10)
1-p(0)=P(1)+p(2)+p(3)+....p(10)
or
1-p(0)= p(at least one)
p(0)=
