SAT - SECTION 2 25 -99 Practice SAT SECTION 2 25 Questions. You have 30 minutes to finish. -21 The following information is for your reference in solving some of the problems. Definition of symbols: = is equal to <> is unequal to <= is less than or equal to >= is greater than or equal to < is less than > is greater than || is parallel to _|_ is perpendicular to On this test there is an additional symbol you should be aware of: "/" indicates division. 6/3 means 6 divided by 3. Circle of radius r: 2 Area = ¸ x r ; Circumference = 2 x ¸ x r. The number of degrees of arc in a circle is 360. The measure of degrees in a straight angle is 180. Triangle: The sum of the measures in degrees of the angles of a triangle is 180. If angle CDA is a right angle, then (1) area of triangle ABC = (AB x CD)/2 2 2 2 (2) AC = AD + DC Note: Figures which accompany problems in this test are intended to provide information useful in solving the problems. They are drawn as accurately as possible EXCEPT when it is stated in a specific problem that its figure is not drawn to scale. All figures lie in a plane unless otherwise indicated. All numbers used are real numbers. 2 On an outstanding balance of $480.00, find the monthly finance charge based on a yearly rate of 18 1/2%. $88.80 $7.40 $10.00 $8.80 $4.00 4 The birth rates for twins in three cities are: City A - 3 sets of twins per 1000 births; City B - 54 sets of twins per 10,000 births; City C - 600 sets of twins per 100,000 births.
