Is the decimal form of 13/3 a rational number.

Answer with explanation:

→A number is said to be rational number , if it can be written in the form of

, where q≠0.

→A rational number is said to be terminating decimal if denominator of rational number is in the form of

otherwise , it is non terminating repeating decimal.

→The given Rational number is

Here denominator contains neither powers of 2 , nor powers of 5, nor power of 2 × 5, so it is a non terminating repeating decimal , still a rational number.

answer: (c) m∠qpo + (2x + 16)° = 180°

step-by-step explanation:

the opposite angles of a quadrilateral are supplementary.

so, ∠o + ∠q = 180°   and   ∠p + ∠r = 180°

since ∠r = 2x + 16°, we can use substitution as follows:

∠p + ∠r = 180°

∠p + (2x + 16)° = 180°

dilation scale factor 2: starting with δabc, draw the dilation image of the triangle with a center at the origin and a scale factor of two. notice that every coordinate of the original triangle has been multiplied by the scale factor (x2). dilation with scale factor 2, multiply by 2.
