QUESTION: 65

What is the tenth term of the pattern below?

Option A
Option B
Option C
Option D
Option E

Answer(s): A

Explanation:

The denominator of each term in the pattern is equal to 2 raised to the power given in the numerator. The numerator decreases by 1 from one term to the next. Since 10 is the numerator of the first term, 10 9, or 1, will be the numerator of the tenth term.21= 2so the tenth term will be1/2.

QUESTION: 67

27.5 degrees
45 degrees
55 degrees
70 degrees
110 degrees

Answer(s): D

Explanation:

LineOB lineOC, which means the angles opposite lineOBandOC(anglesCandB) are congruent. Since
angleB= 55 degrees, then angleC= 55 degrees. There are 180 degrees in a triangle, so the measure of angle O is equal to 180 (55 + 55) = 180 110 = 70 degrees. Angle O is a central angle. The measure of its intercepted arc, minor arcBC, is equal to the measure of angle O, 70 degrees.
