Answer:
B: Y=1/2×+2 I think that's it
This is the concept of proportionality, we are required to calculate the total time it will take the two men to complete the job given that:
Sam would take 4 days and the trainee would take 6 days;
Here proceed as follows;
Proportion of worked completed by Sam in 1 day will be:
1/4
Proportion of work completed by the trainee in 1 day will be:
1/6
Proportion of worked completed by them working together in 1 day will be:
1/6+1/4
=5/12
Time taken for the to complete the entire wall will be:
12/5
= 2 2/5 days
Answer:
Answer is 2 root under 20
If 45%=125
100%=?
Cross multiply
100×125/45
12500/45=277.777778
Because your question has the word about it doesn't mean exactly so when you round off 277.777778 to a full number it will be 278 so the answer is 278.
