Given
There is liter of pure alcohol
Suppose liters of water is added
After addition of water, alcohol becomes 45% in concentration
Thus, of water is added to the pure alcohol.
Answer:
6 < x
Step-by-step explanation:
4(3x + 2) <5(3x - 2)
Distribute
12x +8 < 15x -10
Subtract 12 x from each side
12x +8-12x < 15x-12x -10
8 < 3x - 10
Add 10 to each side
8+10 < 3x-10+10
18 < 3x
Divide by 3
18/3 < 3x/3
6 < x
Answer:
( 5 x 10 ) cm
Step-by-step explanation:
Given:
- The dimensions of the bar are:
( 2 x 5 x 10 ) cm
Find:
Which two faces with dimensions ( _x _ ) should be connected to get smallest possible resistance.
Solution:
- The electrical resistance R of any material with density ρ and corresponding dimensions is expressed as:
R = ρ*L / A
- Where, A: cross sectional Area
L: The length in between the two faces.
- We need to minimize the electrical resistance of the bar. For that the Area must be maximized and Length should be minimized.
- A_max & L_min ---- > R_min
(5*10) & ( 2) ------> R_min
Hence, the electrical resistance is minimized by connecting the face with following dimensions ( 5 x 10 ) cm
