    Assignment:Find the solution set of inequality -30x*x+3300x-90480 ≥0 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
        -30 * x * x + 3300 * x - 90480 ≥0         (1)

---

    From inequality(1)：
         52 ≤ x ≤ 58

---

    The final solution set is :
         52 ≤ x ≤ 58
