At 14:32 bakit hindi po just nilagyan ng +6 sa numerator ng t/24? Pero at 7:24 nilagyan po ng +3 yung numerator...

@KippapEducation 5 ай бұрын

You can add +4 sa numerator ng t/24 and makukuha mo agad yung final answer na 10.

good day sir vj. ask ko lang po sana kung paano gamitin yang formula kung by pair ng work ang given, na parang ganito [EE Board April 1996] A and B can do a piece of work in 42 days, B and C in 31 days and C and A in 20 days. In how many days can all of them do the work together?

@KippapEducation 3 ай бұрын

Set up the 3 equations: 42/A + 42/B = 1 31/B + 31/C = 1 20/A + 20/C = 1 Let x = 1/A, y = 1/B, z = 1/C then plug in sa calcu (3 eqs, 3 unknowns) 42x + 42y = 1 and so on Get the reciprocal of x, y, and z to find the rate of A, B, and C Then plug in sa final equation t/A + t/B + t/C = 1 t = 18.85 days

Pano po ba sir pag ganito na po ang problem? paano po ito e input sa equation? Twelve men can finish the job in 16 days. Five men were working at the start and after 8 days 3 men were added. How many days will it take to finish the job?

@KippapEducation 4 ай бұрын

Find the rate of each man: 12*(16/r) = 1 r = 192 days Plug in to equation: 5*(8/192) + (5+3)*(t/192) = 1 t = 19 more days Answer = 8 + 19 = 27 days

Pwede ba to masolve gamit yang formula na summation of t/r=1 "A reservoir is filled through its inlet pipe and then it is emptied through the outlet pipe, in a total time of 9 hours. If water enters through the inlet and is simultaneously allowed to leave through the outlet, the reservoir is filled in 20 hours. How long will it take to fill the reservoir if the outlet is closed? " di ko maindentify san yung t at r dapat.

@KippapEducation 5 ай бұрын

Let A = rate ni inlet B = rate ni outlet A+B = 9, kasi it takes 9 hours for A to fill and then B to empty Then plug in sa equation where they are used simultaneously 20/A + 20/B = 1 20/A + 20/(9-A) = 1, then solve for A A = 4 hrs, B = 5 hrs

@@joshuadosdos2245 compute for the rate of each man. 20(15/R)=1, R = 300 Then use the formula: 10(6+t)/300 + 10(t/300) = 1 t = 12 Total days: 6 + 12 = 18 Delay = 18 - 15 = 3
