Is the clarity in clear lime water "Deng" or "Cheng"?

Is the clarity in clear lime water "Deng" or "Cheng"?

Clarify the verb D è ngq ī ng to make impurities precipitate and liquid clear
Clarify the verb ch é ngq ī ng, clear up the confusion; & adjective, clear
Clarified limewater can be understood as "clarified limewater" and "clarified" is an adjective,
So it reads ch é ngq ī ng

(20 points) is the word "Cheng" pronounced "Deng" or "Cheng"

A has 24 tons of grain in stock and B has 30 tons of grain in stock. Now, after the same grain is transported from the two warehouses, the remaining grain in warehouse A is 5 / 8 of that in warehouse B, and the two warehouses each transport grain
How many tons?

A ton each
that
（24-a）=5/8（30-a）
24x8-8a=150-5a
3a=42
A = 14 tons
14 tons each

10.15-3.75 + 7.85-6.25?

=(10.15+7.85)-(3.75+6.25)
=18-10
=8

It is known that the sum of the first five terms of a positive proportional sequence is 3, and the sum of the first 15 terms is 39, then the sum of the first 10 terms of the sequence is ()
A. 32B. 313C. 12D. 15

Let the sum of the first n terms of the sequence be SN. From the meaning of the title, we can get S5 = 3, S15 = 39. From the properties of the equal ratio sequence, we can get that S5, s10-s5, s15-s10 are still equal ratio sequence, that is, (S10 − 3) 2 = 3 (39-s10). From the solution, we can get S10 = 12, or S10 = - 9

For any nonzero rational number a and B, a new operation is defined

Let a and B be natural numbers, define the new operation as: a # B = 2 (a + b) calculation: (1) 2 # 6 = (2) 5 # (8 # 4) =? Just now this is too simple, this is the difficult problem. Let a and B be non-zero natural numbers, define the new operation symbols as # and *, we know that a # B = a × B, a * b = a + B. (1) calculation: 2 * [(4 * 5) *

How many are the five digits of 12345? What is the 95th digit

This is a permutation. There should be 5 * 4 * 3 * 2 * 1. If we say from small to large, the 96th number is 45321, so the 95th number is smaller than it, 45312

Are similar matrices and congruent matrices diagonal
The contract matrix must be a diagonal matrix, and the similar matrix is not
In other words, are real symmetric congruent matrices and similar matrices diagonal
If the common n-order matrix A, is the similarity matrix and the congruent matrix diagonal

A real symmetric matrix must be similar to a diagonal matrix
Ordinary matrices may not be similar diagonalized
A and B contract definition: a = P '* b * p;
Similar definitions of a and B: a = inv (P) * b * p; [inv is the inverse operation]
So if P is a unitary matrix (p * p '= I), contract is equivalent to similarity
I hope it helps
