Answer the following questions. You are not expected to show details for this sections. and no partial mark will be given. (a) Evaluate $300 times 1 - 1/(1 + 6 xy)^x/0.03, accurate to the cent (b) Margot's grades and course credits in her first semester at college are listed below Using the table below for converting letter grades to grade point values, calculate Margot's grade point average for the semester. (c) Simplify 15x - (4 - 2(5x - 6)). (d) Simplify x^5 times x^6/x^9. (e) What percent of $950 is $590?Explanation / Answer
B.
Total credits earned = 5+3+4+ 2+3+4 = 21
Max grade point to be earned = 21*4 = 84
grade points earned by student = 5*2.3 + 3*2.7 + 4*3.3 + 2*1.7 + 3*3 + 4*2 = 53.2
grade point average = 53.2/21 = 2.53
C.
15x - (4 - 2*(5x - 6))
= 15x - (4 - 10x + 12)
= 15x - (16 - 10x)
= 15x - 16 + 10x
= 25x - 16
D.
(x^5*x^6)/x^9
= x^(5 + 6)/x^9
= x^11/x^9
= x^(11 - 9)
= x^2
E.
% = 590*100/950 = 62.105%
