Because when you multiply by 10, it adds a zero to the end of the number, like 12*10 = 120, so vise versa for dividing
Answer:
B
Step-by-step explanation:
angles on the circumference of a circle subtended on the same arc are congruent , then
x = 52°
If you rounded off 129 to the nearest ten the answer would be 130
Answer:
( x - 2 )^2 + ( y - 1 )^2 = 1
Step-by-step explanation:
As i previously explained,
The general form of equation for a circle is ( x - h )^2 + ( y - k )^2 = r^2.
h and k are the co-ordinates of the center of circle and r is the radius
Here, We have (2,1) as the co-ordinates of the center of circle
Now,
( x - h )^2 + ( y - k )^2 = r^2
or,( x - 2 )^2 + ( y - 1 )^2 = r^2
The radius of the circle is 1 units(from figure)
So, put that in, we get
( x - 2 )^2 + ( y - 1 )^2 = 1^2
or, ( x - 2 )^2 + ( y - 1 )^2 = 1
You can simplify this or leave it here.
86.60 rounded to the nearest dollar would be 87 dollars
