It's best to explain the idea Xiao Li read a book. On the first day, she read 1 / 9 of the whole book. On the second day, she read 35 pages. The ratio of the number of pages she read in two days to the total number of pages in the whole book is 1:4. How many pages are there in this book? Come on, I'm in such a hurry

The ratio of the number of pages she read in two days to the total number of pages in the whole book is 1:4. How many pages are there in this book? Come on, I'm in such a hurry

The number of pages read in two days is 1 / 4 of that of the whole book. The number of pages read in the first day is 1 / 9 of that of the whole book. Then the number of pages read in the second day is 1 / 4-1 / 9 = 5 / 36, which is 35 pages
35/（5/36） =252
So the book has 252 Pages

Thank you very much,
1.——fired,your health care and other benefits will not be immediately cut off.
A.Would you be B.Sould you be C.Could you be D.Might you be
2.John promised his doctor he___ not smoke,and he has never smoked ever since.
A.might B.should C.could D.would

A.would,will B.must,may C.should,must D.need,dare

D promised his doctor that he would not smoke. Since he agreed, he should be very sure that he would not smoke. Maybe it is not feasible. 3. C won't let me out late. A "could" here is also feasible, but I will choose C4. A. It's very difficult

In the supplementary explanation, we should be specific
If there are two elements Z and y, and the number of protons in Z is 9 less than that in Y, y and Z can form a 42 electron negative monovalent anion. What are the two elements?

Z is oxygen and Y is chlorine~
It's chlorate
You can set the number of nuclear charges one as a and the other as a + 9
Then according to 1:1.1:2 and other equations to try ~ try out is this

Explain the problem from the molecular point of view
【1】 Wet clothes dry faster in the sun than in the room. [2] a fully inflated bicycle tire is prone to tire burst if it is exposed to the sun for a period of time. [3] the number of bottles containing alcohol and gasoline is reduced after being kept open for a period of time

The sun will cause the temperature to rise. At a higher temperature, the molecules will move faster. Once the water molecules move faster in the sun, the clothes will dry faster. Similarly, the gas molecules will move faster and become more intense, which will lead to greater pressure in the tire and eventually burst the tire, The molecules in alcohol and gasoline will evaporate after a period of time
