It doesn't come from the rapour.
3Does it come from the water in the river?

数学:
1 :设需要再加入x千克30%的盐水.
20%×10+30%x=22%(x+10)
解得x=27.5
答:应加入27.5千克浓度为30%的盐水.
2:因为由题已知得正方形边长为根号30.连接对角线(由左至右的下降线,正方形的)又因为在正方形中,所以左下角的度数为90.所以对角线就等于根号下30加上30,就等于4倍的根号15.又在正方形中,对角线平分右下角,就平分成45度和45度.又因为在同一圆中,所以对角线平分整个扇形且等于扇形的俩个边.所以俩个边长度为4倍根号15.所以S扇=360分之90乘以π乘以240(4倍根号15的平方).得出结果在减去正方形面积30就行了.
