Divide total miles by her speed:
166.4 / 52 = 3.2
She drove for 3.2 hours.
Answer: b. helium nucleus
Helium nucleus is the particle that is being emitted in an alpha radiation. This helium nucleus then transforms and becomes decays that are also known as alpha decays. The alpha particle maybe similar to helium nucleus however, it does not have electrons surrounding it.

<u>Quadrilaterals</u> are <em>plane shapes</em> that are <u>bounded</u> by four <u>straight</u> sides. Thus, the required answers to the questions are:
46. True. Other examples include kites, rhombus, etc.
47. False.
46. When a <em>plane shape</em> is <u>bounded</u> by four <u>straight</u> sides of equal or different lengths, it is called a <u>quadrilateral</u>. Examples include trapezium, kite, rhombus, rectangle, square, etc. Each of these examples has individual <u>properties</u>.
Thus the required answer to question 46 is; <u>True</u>. It can be observed that with respect to their <em>individual properties</em>, other <u>quadrilaterals</u> which have a pair of <em>opposite angles</em> to be <u>equal</u> include: kite, rectangle, rhombus, etc.
47. A <em>ray segment</em> is a given <u>line</u> that <u>points</u> or <u>heads</u> in a specific direction. So that the direction in which the ray moves is very<em> important</em>.
Thus in the given question, the <u>required</u> answer is; False. This is because the<u> two</u> given rays are moving in opposite directions. Though the two rays may have the <u>same</u> length of the <u>segment</u>.
