1 cup of water: 750-450) to orange (5-2) 100 (grams).

1 empty bottle before the weight of the branch:

450-100x2

250 (gram repentance).

How many cylinders are there with a cylinder with a base radius and height of 1 and a number of cylinders with a base radius and height of 2, and the sum of their dispersion products is 50 (pai) and the sum of the surface area is 120 (pai).

Let the bottom radius and height of the cylinder x and the bottom radius and height of the cylinder y be 2.

The volume of the cylinder with a base radius and height of 1 is , and the surface area is 2 +2 =4 The volume of the cylinder with a bottom radius and height of 2 is 2 2 2 =8, and the surface area is 2 2 2 + 2 2 2 = 16

x+8y=50

4x+16y=120

x=10y=5

So there are a total of 10+5=15 cylinders.

Don't change, this is the object preposition, fixed usage:

This kind of object is preceded, and two conditions must be met: first, the object must be a pronoun; The second is that it must be a negative sentence, which is expressed by negative words such as "no", "not", "no", "no", "mo", "fu" and so on.

The whole sentence translated into the vernacular is: not afraid that people do not understand themselves, they are afraid that they do not understand the meaning of others here, in fact, in ancient texts, many times this word is meaningless, self-knowledge is an active relationship, and confidant is a passive relationship.

After changing it, the meaning of the previous sentence has changed a little, so it's best not to change it.

People always blame others for not understanding themselves, and they don't think about whether they understand others.

Excerpted from Mr. Nan Huaijin's "Analects".

First, an array variable is a memory address that points to the first element of the array. Regardless of how the array is several, it is sequential in memory.

int a[2][3][4]=;

Stored in memory:

a, &a are the memory addresses that point to the first element.

a[0], &a[0] point to the 0 offset of the first element, or the memory address of the first element.

a[0][0], &a[0][0] are 0 offsets to a[0], &a[0], and are still the memory address of the first element.

And so on.

A1=26, N2=8, A2=65 N3=11, A3=122, N4=5, N4=N1, Three One Cycle Mountain Mu, 2014 3=671....1. Liquid friend A2014=A1=26

It's not easy to tease the problem, it's not difficult to praise it, please praise it, thank you for your support!
