The volume of a cube whose edge has the length of 2 23 8. Thus the sum of the volumes of the two cubes 8 1 9. Math Refresher H 313 11. 105 Use Strategy 11 Use new definitions carefully. These problems are generally easy. Given - Thus f - 115 1 15 14 2 105 Math Refresher H 431 12. 0 Given r 9 E s2 25 E Use Strategy 17 Use the given information effectively. From E and E we have r 3 or -3 E s 5 or -5 E The greatest possible value of s - r occurs when s is a maximum and r is a minimum or 5 - -3 8 0 The greatest possible value of r - s occurs when r is a maximum and s is a minimum or 3 - -5 8 0 The answer to this question is the difference between E and Ẹ 8 - 8 0 Math Refresher H 430 and Logical Reasoning 13. 331 which translates to 33.3 in grid 3 form. Use Strategy 2 Translate from words to algebra. According to the graph 4 people had green eyes 6 people had blue eyes and 5 had brown eyes so there were 15 people in the group. The percentage X can be found by setting up the ratio X 5 1 1 _ _ 1. 100 3 3 or X 33-3-. 333 had brown eyes. Math Refresher H 704 14. 5 N5 LM 385 385 4235 Use Strategy 17 Use the given information effectively. From the given problem we see that N5 X M 385 Use Strategy 7 Use numerical examples Try N 1 15 X M 385 M must be greater than 10 which is incorrect. Try N 2 25 X M 385 M must be greater than 10 which is incorrect. Try N 3 35 X M 385 M must be greater than 10 which is incorrect. Try N 4 45 X M 385 M is not an integer. Try N 5 55 X M 385. Thus M 7 Therefore L can be equal to 7 to give 55 X 77 385 385 4235 Logical Reasoning ALTERNATE METHOD 834 SAT PRACTICE TEST 3 - SECTION 6 ANSWERS The number N5 can be written as 10N 5. For example 25 10 X 2 5. So we have 10N 5 X M 385 T in the multiplication example .
