Today is Saturday. What day is the next 30 days? How to practice the formula?

30/7=4…… Two days after Saturday is Monday

It is known that the opening day of Shanghai World Expo is Saturday, so what day is its closing day? (how to list the ceremonies?)

Sunday, October 31

Math problem: May 1, 2010 is Thursday, so what day is May 31, 2010?

[31+(4-1)]/7=4.6
May 1st, 2010 is Thursday, so May 31st, 2010 is Saturday

From May 1st to October 31st, 2010, Shanghai World Expo has gone through many stages______ May 1st is Saturday, October 31st is Sunday______ ．

From May 1 to May 31, 2010, 30 days passed; 30 + 30 + 31 + 31 + 30 + 31 = 183 (days); from May 1, 2010, the number of days passed should be 1183 + 1 = 184 (days); 183 △ 7 = 26 (weeks) One day after Saturday is Sunday

Can all kinds of rocks be transformed into sedimentary rocks?
Which is not OK?

No

The rocks with different genetic classification are ()
A. Limestone B. shale C. sandstone D. marble

Limestone, shale and sandstone are sedimentary rocks, while marble is metamorphic rocks, so marble is different from other classifications

High school geography tells me what kind of rocks these belong to
Talc gypsum calcite fluorite apatite feldspar Topaz corundum can be better at adding a little common, thanks

These are minerals, which are the components of rocks. Rocks are mainly divided into magmatic rocks, sedimentary rocks and metamorphic rocks

Geography is a little difficult now. The topic of morning and evening line is a little vague. I hope you can give me some advice!
Thanks!

Along the direction of the earth's rotation, from night to day is the morning line
From day to night is the faint line

What are the beneficial effects of human activities on the surface morphology
A the Amazon plain is heavily deforested
B. a large number of lakes were reclaimed in the middle and lower reaches of the Yangtze River
C. build a large number of terraces to expand the area of cultivated land
D land reclamation in the Netherlands
Let's talk about everything

d
A will cause ecological damage
B will reduce the regulating effect of lakes and aggravate drought and flood disasters
C if terraces are built on steep slopes, it will cause soil erosion
D rational use of low-lying characteristics, increase land area

Who can tell me how to judge the morning and evening line in senior one geography

To be simple, remember eight words
Left night is morning, right night is dusk
If the left side of the morning and evening line is night, then this line is morning line. If the right side is night, then this line is dusk line
