Answer:

  6

Step-by-step explanation:

The overbar means the digit repeats indefinitely. The repeating decimal 0.333... is equivalent to 1/3, so this is the simple addition ...

  3 2/3 + 2 1/3 = 5 3/3 = 6

_____

<em>Comment on the repeating decimal</em>

1/3 = 0.3333... repeating is one of the first decimal equivalents you learn.

__

If you're into repeating decimals. you may have learned how to convert them to fractions:

  x = 0.3333... repeating . . . . . . . give a name to the value

  10x = 3.3333... repeating . . . . . multiply by 10^p where p is the number of digits in the repeating pattern

  10x - x = 3.3333... - 0.3333... = 3 . . . . . subtract: the repeating portions cancel

  9x = 3 . . . . . . . . . .simplify

  x = 3/9 = 1/3 . . . . .divide by the x-coefficient; simplify

In the figure AB =6cm, triangle AOB =60°
viva [34]

Answer:

From the basics of algebra,

a triangle subtended to the center of a circle from the circumference is always isosceles

since the Central angle is 60 and the triangle is isosceles, the other angles are,

\frac{180 - 60}{2}  = 60

meaning that the triangle is equilateral.

all the other angles are 60.

the radius of the circle is the length of the triangles side,

ie 6cm

write a conjecture as to the number of sides as compared to the number of triangles formed when drawing diagonals from one verte
zmey [24]

Answer:The Collatz conjecture is a conjecture in mathematics that concerns a sequence defined as follows: start with any positive integer n. Then each term is obtained from the previous term as follows: if the previous term is even, the next term is one half the previous term. If the previous term is odd, the next term is 3 times the previous term plus 1.

Step-by-step explanation :an opinion or conclusion formed on the basis of incomplete information.
