In a 40 cm long, 25 cm wide, 20 cm high cuboid water tank into 15 cm deep water How many centimeters will the water surface rise when immersed in water?
The water surface will rise to (40 × 25 × 15 + 10 × 10 × 10) / (40 × 25) = 16 cm
Put a cuboid water tank 40 cm long, 30 cm wide and 10 cm high into a cube with an edge length of 5 decimeters. How many centimeters deep is it?
Examination questions, we have more than 30 kinds of answers, I can't tell, what is the correct answer, how to think? Please answer quickly
4.8cm, 30x40x10 / (50x50) = 4.8
A cuboid water tank, 40 cm long, 20 cm wide, 30 cm high, 15 cm deep. Now put a cube stone with 10 cm edge length into the tank
Water, how high is the water tank?
Divide the total volume by the area of the ground
(40x15x20+10x10x10)/(40x20)=16.25
The result is less than the tank height, so the final water height is 16.25 cm

Take (x-3) in (x-3) &# 178; - 2 (x-3) - 5 (x-3) &# 178; + (x + 3) as a factor to merge the similar terms, and the result is?
Original formula = - (x-3) - 4 (x-3) ^ 2 = - (x-3) (1 + 4x-12) = (x-3) (11-4x)
If the solution set of inequality 2ax-3a > 4 + 3x is x > 4 + 3A / 2a-3
The solution set of 2ax-3a > 4 + 3x is x > 4 + 3A / 2a-3
(2a-3) x > 4+3a
x > ( 4+3a) / (2a-3)
( 4+3a) / (2a-3)= 4+3a/2a-3
2a-3 > 0 is enough
a> 3/2

The position of the number a on the number axis is shown in the figure, then the absolute value of 2-A
Note: A is bigger than 2. If it is good, 60 points will be given
As for your graph, if there is no graph and a is on the right side of 2 on the number axis, then | 2-A | = A-2
Given that the monotone increasing interval of the function y = x & # 178; - BX + 5 is (2, + ∞), find the value range of B
Axis of symmetry x = - (- b) / (2 * 1) = B / 2
The monotone increasing interval of the function is (2, + ∞), only the symmetry axis B / 2 ≤ 2, B ≤ 4
