26.5 divided by 1.2, the quotient is 22, and the remainder is (0.1)
The quotient of 2.57 divided by 16 is 0.16, and the remainder is (0.01)
0.5,1.5,4.5…… The fourth number is (13.5)
3:30 is equal to (3.5)



22 divided by 26, why is the remainder not - 4, but 22?
I already know the answers, but none of them are complete


The remainder must be a positive integer
And the remainder must be less than the divisor
For example, 7 △ 3 = 2 one
It can't be 3 -1
Or 1 four



If a number is divided by 23, the quotient is 16, and the remainder is the largest______ When the remainder is the largest, the divisor is______ .


The maximum remainder is: 23-1 = 22, 23 × 16 + 22 = 368 + 22 = 390 answer: the maximum remainder is 22, when the maximum remainder, the divisor is 390; so the answer is: 22390



An iron bar is folded into a right triangle ABC shape, and the triangle at the end a is pulled by a rope to drop freely. Then the proportion of the extended chord BC side of the rope is calculated~


Is this a math problem?
According to the knowledge of physical moment
The extension line of the rope must pass through the center of gravity, otherwise it will not be stationary. Because it is hung at point a, this line is a central line of ABC
So the ratio is 1:1



Given a square + AB = 10, b square - AB = 7, then a square + b square =, a square + 2Ab - b square=


A ^ 2 + AB = 10 -------- (1), B ^ 2-AB = 7 ------ (2) (1) + (2) get a ^ 2 + B ^ 2 = 10 + 7 = 17 (1) - (2) get a ^ 2 + 2ab-b ^ 2 = 10-7 = 3, please accept the answer, thank you!



Y = 10 (x ^ 2) + 22x, when x = 50, how much is dy / DX


dy/dx =20x+22
When x = 50
dy/dx =1000+22=1022



There are 38 students in the class, including 10 who watch cartoons and 20 who watch TV. What percentage of them are watching cartoons?


10÷20=50%
A: the number of people watching cartoons accounts for 50% of those watching TV



Let f (x) = x2-2x + 2, the minimum value of X ∈ [T, t + 1] (t ∈ R) be g (T), and find the expression of G (T)


F (x) = x2-2x + 2 = (x-1) 2 + 1, so the symmetry axis of the image is a straight line x = 1, and the opening of the image is upward. ① when t + 1 < 1, i.e. T < 0, f (x) is a decreasing function on [t, t + 1], so g (T) = f (T + 1) = T2 + 1; ② when t ≤ 1 ≤ T + 1, i.e. 0 ≤ t ≤ 1, the function f (x) gets the minimum value at the vertex, i.e. g (T) = f (1) = 1; ③ when t > 1, f (x) is at [T, t + 1] In conclusion, G (T) = T2 + 1 & nbsp;, & nbsp; & nbsp; T < 01 & nbsp;, & nbsp; & nbsp; 0 ≤ t ≤ 1t2 − 2T + 2 & nbsp;, t > 1



If f (x) = cosx / e ^ x, then the derivative is


F(x)= cosx/e^x
∴F'(x)=[(cosx)'*e^x-cosx*(e^x)']/(e^x)²
=(-sinx*e^x-cosx*e^x)/(e^x)²
=(-sinx-cosx)*e^x/(e^x)²
=(-sinx-cosx)/e^x



Can you solve the following problems by using the equation method you have learned? In order to further alleviate traffic congestion, Wuxi City decided to build a light rail from the city center to the airport. In order to complete the project three months ahead of schedule, the original work efficiency needs to be increased by 12%. How many months will it take to complete the project?


Suppose the original plan takes x months to complete the project. According to the meaning of the question, we can get: (1 + 12%) · 1 x = 1 x − 3 solution, x = 28 & nbsp; after testing, x = 28 is the solution of the original equation. Answer: the original plan takes 28 months to complete the project
