Answer: the excess skin is surgically removed
Step-by-step explanation:
Answer:
3rd option
Step-by-step explanation:
You first notice that 12 and 75 are multiples of 3. Your expression becomes
. At this point you should recognize it's
and
. The second term gets factored as a difference of squares: ![3(2y+5)(2y-5)](https://tex.z-dn.net/?f=3%282y%2B5%29%282y-5%29)
Answer:
18:24 or simplest form is 3:4
Step-by-step explanation: If you don't need to simplify then it is 18:24, but if you simplify it by dividing 18 and 24 by 6, then the answer is 3:4 :)
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
