15 electricians worked for 24 days to the whole job, now, there are 15 of them, so on any given day, each electrician worked one whole day, in 24 days, that one electrician worked 24 days total.
now, there were 15 electricians on any given day though, since each one of them worked the whole day that one day, so the "days work worth" on a day is 15, so the house gets 15days worth of work because of that.
so how many "days worth" did all 15 do on the 24 days, well, 15+15+15+15+15+15+15+15+15+15+15+15+15+15+15+15+15+15+15+15+15+15+15+15, namely 15 * 24, or 360 days worth of work.
since it takes 360 days worth of work to do the whole wiring, in how many days would 18 electricians do it? 360/18.
2(x+2) > x+5

2x+4-x > x+5-x
x+4 > 5
x+4-4 > 5-4

Christine crawled:
3 ft* (3/4)= 2.25 ft.
3 ft+ 2.25 ft= 5.25 ft
We already know that 1 ft= 12 in.
5.25 ft* (12in/ 1 ft)= 63 in.
The total distance the two children crawled together is 63 in~
ANSWER
6.4 hours
EXPLANATION
if it takes 10 hours to get 50%, then it will take less number of hours to get 32%
We use proportion to solve this question.
If less more divides.
The number of hours it will take to get 32% is
Hence it will take 6.4 hours to get 32%
Answer:
25% decrease
Step-by-step explanation:
Percent change can be found by doing difference/original
(950,000 - 712,500) / 950,000
