(含答案)九年级数学人教版上册课时练第25章《25.1.1 随机事件》(1)
答卷时应注意事项１、拿到试卷，要认真仔细的先填好自己的考生信息。
２、拿到试卷不要提笔就写，先大致的浏览一遍，有多少大题，每个大题里有几个小题，有什么题型，哪些容易，哪些难，做到心里有底；３、审题，每个题目都要多读几遍，不仅要读大题，还要读小题，不放过每一个字，遇到暂时弄不懂题意的题目，手指点读，多读几遍题目，就能理解题意了；容易混乱的地方也应该多读几遍，比如从小到大，从左到右这样的题；４、每个题目做完了以后，把自己的手从试卷上完全移开，好好的看看有没有被自己的手臂挡住而遗漏的题；试卷第１页和第２页上下衔接的地方一定要注意，仔细看看有没有遗漏的小题；５、中途遇到真的解决不了的难题，注意安排好时间，先把后面会做的做完，再来重新读题，结合平时课堂上所学的知识，解答难题；一定要镇定，不能因此慌了手脚，影响下面的答题；６、卷面要清洁，字迹要清工整，非常重要；７、做完的试卷要检查，这样可以发现刚才可能留下的错误或是可以检查是否有漏题，检查的时候，用手指点读题目，不要管自己的答案，重新分析题意，所有计算题重新计算，判断题重新判断，填空题重新填空，之后把检查的结果与先前做的结果进行对比分析。

所以 AC ＝ 2 − 2 ＝ 252 − 152 ＝20（m）.
在Rt△ CDE 中，因为 DE ＝ AB ＝25 m， CD ＝ BC ＋ BD ＝15＋5
＝20（m），
所以 CE ＝ 2 − 2 ＝ 252 − 202 ＝15（m）.
故梯子滑动后，梯子的高度 CE 是15 m.

解：（1）因为长方形绿地的长 BC 为 128 m，宽 AB 为 98 m，
所以长方形 ABCD 的周长为2×（ 128 ＋ 98 ）＝2×（8 2 ＋

故长方形 ABCD 的周长为30 2 m.
