,Questions about how fast people can do a job together?If the first painter
can do the entire job in twelve hours and the second painter can do it in
eight hours, then (this here is the trick!) the first guy can do 1/12 of the
job per hour, and the second guy can do 1/8 per hour. How much then
can they do per hour if they work together? - ACCURATE
ANSWERS✔✔ Take each number of hours and use 1/x amount of
hours.
Example: To find out how much they can do together per hour, I add
together what they can do individually per hour: 1/12 + 1/8 = 5/24.They
can do 5/24 of the job per hour. Now I'll let "t" stand for how long they
take to do the job together. Then they can do 1/t per hour, so 5/24 = 1/t.
Flip the equation, and you get that t = 24/5 = 4.8 hours.
1/12 + 1/8 = 1/t
5/24 = 1/t
24/5 = t
=4.8 hours
One pipe can fill a pool 1.25 times faster than a second pipe. When both
pipes are opened, they fill the pool in five hours. How long would it take
to fill the pool if only the slower pipe is used? - ACCURATE
ANSWERS✔✔ hours to complete job:
fast pipe: f
, slow pipe: 1.25f
together: 5
completed per hour:
fast pipe: 1/f
slow pipe: 1/1.25f
together: 1/5
adding their labor:
1/f + 1/1.25f = 1/5
multiplying through by 5f:
5 + 5/1.25 = f
5+4=f=9
Then 1.25f = 11.25, so the slower pipe takes 11.25 hours.
How much pure acid must be added to 12 ounces of a 40% acid solution
in order to produce a 60% acid solution? - ACCURATE ANSWERS✔✔
P1*V1 + P2*V2 = P3*V3
P1*V1 would be X*1
P2*V2 is volume of first*percentage of first
