3. "(Indicates the symbol used in the comment section of the article.) This type of annotation is a clip that is sandwiched in the middle of the text. Writing an article to a certain place, in order to make the reader understand more thoroughly, sometimes it is necessary to add a note.

Origin of punctuation:

Punctuation was originally invented to facilitate recitation. In the past, there were many illiterates, and a small number of literate people had to read the words to others on a regular basis. In order to facilitate recitation, the text began to have a "dot" sign.

The word puntuation is derived from the Latin puntus, which means "point". These "points" let the reader know that **there needs to be a pause, ** the tone needs to be strengthened, etc. Western punctuation originated in ancient Greece, and was written in conjunction with Greek in the 5th century before the Common Era.

Are you in a hurry?

No matter how urgent it is, don't say what the problem is. What's the use?

Solution (2) Buy only the two items you like in one supermarket (both items are purchased in the same supermarket!) Categorical discussions.

A supermarket has a 20% discount on all items. The sum of the two items** is 452 yuan.

After discount, it is 452* yuan.

b supermarket shopping over 100 get 30 shopping coupons (less than 100 no coupons).

I bought a walkman for 360 yuan [400 yuan for my own and 40 yuan for the remainder.] ] returned 3 * 30 = 90 yuan shopping coupon.

After purchasing the school bag, there is 38 yuan left.

Finally, analyze how much money he actually spent on his own money, first of all, 360 must! Then 90 yuan of the 92 yuan for buying a schoolbag used the returned shopping coupon, that is, only another 2 yuan was spent. So the actual cost is 360 + 2 = 362 yuan.

To sum up, if both products are purchased in one supermarket, you should choose A supermarket! Compared with B supermarket, it costs less yuan.

If you can buy the two items you like in two shopping malls separately. There is also a need for categorical discussions.

Walkman purchase options.

A supermarket: 360* yuan.

B supermarket: 360 yuan [It should not be allowed to spend 360 to take a shopping coupon and come back to buy this.] ]

School bag purchase options.

A supermarket: 92* yuan.

B supermarket: 92 yuan (same as above).

Then there is the combination: the walkman is bought in A, and the schoolbag is bought in B = 288 + 92 = 380 yuan.

The walkman is bought in B, and the schoolbag is bought in A = 360 + yuan [It doesn't fit the topic.]

Therefore, in summary, (1) if both items are purchased in one supermarket, supermarket A should be chosen.

2) If both items are not required to be purchased in one supermarket, you can only choose to buy the Walkman at A and the schoolbag at B, which costs 380 yuan.

The third question is.

The specific heat of water is c=, the density of water is p=1kg l, and the boiling point of water is t1=100. So, to boil water with a temperature t0=20 and v=2l, the amount of heat required is about q = cxpxvx(t1-t0) = =.

These heats, heated with the electric power of p=840w, take time t = q p = = 800s

That is, it takes about 800 seconds, or minutes, to boil this water at the rated voltage.
