120公斤0号柴油等于多少升

很厉害了.我183,体重72,卧推60KG...

先说你的砂率吧,假设也要专业点呀,50%的C35混凝土配合比砂率?你吓死人了.
再谈砂率的问题,在没有碎石的情况下,砂率从何谈起?砂率是砂的质量除以砂加碎石的和,得到的结果才是砂率.
不过不管怎么样,砂跟水泥拌制的那不叫混凝土,那叫砂浆.
当然是加入石子的强度高.碎石本事就是在混凝土中起到骨架作用,你说是一个有骨头的人跟一个没骨头的人谁能抗更重的东西?通俗的来讲就是这么个意思.
其实不要你提供数据,同样的水灰比之下,肯定是加入石子的强度要高.
我是理论加实践.
看到你的问题补充,我很无奈,我可以明确的告诉你,加石子的强度高.不是模糊的告诉你可能,而是肯定的告诉你,加石子的强度高!

实际=120÷(x+2)=120/(x+2)天

设 原来有x公斤煤 .（1-2／5）x +120=2/3x 120=1/15x x=1800 答：原来有煤1800kg.

混合后水为x度,40kg70度水升到x度时释放的热量：
40*(70-x)*C(水比热）（卡）.
120kg10度水升到x度时吸收的热量：
120*（x-10)C（水比热）(卡）,
放出的热量与吸收的热量相等,
40(70-x)=120*(x-10)
x=25°.

up to

200-120=80公斤，这是五分之一，80公斤=无分之一80÷无分之一就行了

身高吧来的,身高吧 以前有个完美192 就是为了击倒他 说的 类似的很多 你可以去身高吧问192,192已经有3个时代了 3个192都很火 这里是说的是第一个

设小明X,爸爸Y,妈妈Z
X+Y=92
X+Z=80
Y+Z=120
则 （X+Y）-(X+Z)=92-80
Y-Z=12
(Y+Z)+(Y-Z)=120+12
2Y=132
Y=66
代入上面方程式
X=26
Z=54
得出结论 小明26公斤 爸爸66公斤 妈妈54公斤
可以加起来验算一下
