Which fraction below represents a terminating decimal?
9966 [12]
<h3>Answer: C.  3/10</h3>

A terminating decimal only happens when the fraction has a denominator with factors of 2 and/or 5. No other factors are allowed (other than 1).

Something like 1/12 has the denominator 12 with factors 2*2*3. That '3' means we won't have a terminating decimal. Similarly, the fractions 2/9 and 2/3 won't convert to a terminating decimal either.

3/10 on the other hand does convert to a terminating decimal and 3/10 = 0.3

1. Given line segment RB and on it is point C, if RB = 45 and CB = 3x - 12 and RC = 2x + 9, what is the value of x?
marshall27 [118]

Answer:

Step-by-step explanation:

1). If a point C is lying on a line segment RB,

   Then RB = RC + CB

   Since, RB = 45, CB = 3x - 12 and RC = 2x + 9

   45 = (2x + 9) + (3x - 12)

   45 = (2x + 3x) - 3

   48 = 5x

   x = \frac{48}{5}

   x = 9.6

2). Since, RC = 2x + 9

    RC = 2(9.6) + 9

          = 19.2 + 9

          = 28.2 units

3). Distance between the two points (x_1,y_1) and (x_2,y_2) is given by the formula,

  d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

  Distance between the points A(2, -2) and D(-2, 2) will be,

 AD=\sqrt{(2+2)^2+(-2-2)^2}  

         = \sqrt{16+16}

         = 4\sqrt{2}  

         = 5.657

         ≈ 5.66 units
