Ladies and gentlemen, come and help, you help, please, hehe

Although I am a man, in my opinion, your friend's husband may not have "gone wrong". If you were that man, would you miss your previous feelings? Definitely, but family is always the most important, he can distinguish what is friendship and what is family, and I believe that he will have a rational bottom line.

Besides, after a long time, the husband and wife seem to feel as plain as water, so, as a wife, can you add some "sugar" to the glass of water in life? It's just that the two of them saw the old photos and recalled that when they fell in love, I think they were all very romantic.

Let it be! If he can't be trusted, then even if there is no woman, there will be the next one!

And integers 0 and negative numbers Serikayama 0 and positive integers are medium natural numbers 0 and negative integers.

5.Integer: -1, 0, Negative: Beat, -1, -1 4, , Fraction: ,, 13 9

Non-negative numbers: 0, 13 9

f is hydrogen, filtered.

zn + cuso4 = znso4 + cu

The remaining ZN powder in the reaction reacts with sulfuric acid to form hydrogen.

Planned cost material cost = 200 * 10 * 8 = 16000 actual material cost = 220 * 9 * 10 = 19800 according to the actual output analysis = (220-200) * 10 * 8 = 1600, indicating that the actual output increased by 20 and the material cost increased by 1600

According to the analysis of the material consumption quota per unit of product = (9-10) * 200 * 8 = -1600, it means that the actual unit product consumption is reduced by 1 yuan and the material cost is reduced by 1600

According to the analysis of material unit price = (10-8) * 200 * 10 = 4000, the unit price increases by 2 yuan, and the total cost of materials increases by 4000

To sum up: efforts should be made to reduce the unit price of materials and reduce the consumption of materials per unit of product.

1.January. 2.The Siberian high pressure in Mongolia has a small specific heat capacity, low temperature, and the air sinks to form a high pressure zone in the subpolar depression in winter.

3.Northwest wind Northeast wind.

4.Southwest wind The southeast trade wind crosses the equator and is affected by the geostrophic deflection force to the north, forming a southwesterly wind.

There is a significant difference in the thermal properties of land and sea geostrophic deflection forces.
