The equation below shows the area of a trapezoid, A, with a height of 9 cm, and one base 35 cm A = 9 over 2(b + 35). Which of th
e following formulas correctly solves for the other base, b? A. b = 2A over 9 + 35. B. b = 2 multiplied by A over 9 - 35. C. b = 2 multiplied by A plus 35, all over 9 D. b = 2 multiplied by A minus 35, all over 9
B - the other base; A = 9/2 ( b + 35 ) / * 2 ( we will multiply both sides of the equation by 2 ) 2 A = 9 ( b + 35 ) b + 35 = 2 A / 9 b + 35 - 35 = 2 A / 9 - 35 b = (2 A / 9 ) - 35 Answer: B ) b = 2 multiplied by A over 9 - 35
0.75 is equal to 6\8 5.8 is > 4\5 a decimal greater than 5\8 is 1.2 0.2 > 1\4 0.7>0.6 a decimal smaller than 6\8 is 0.01 The one that is not equal to -7\5 is -11\5 The answer is D
So the answer must be 9 for an example 50% of 18 is 9 because to find 50% of something simply divide by 2 .10% of 90 is 9 because to find 10% of something divide by 10. 25% of 36 is 9 because you divide by 4 to get 25% of anything.
