Answer:
1 39/50 hours. This is equivalent to 1.78 hours.
Step-by-step explanation:
The sum of the hours of work and the hours for break gives the work day hour which has been given as 8 hours.
Furthermore, given that the break time is 22 1/4%, the number of hours for break
= 22 1/4% × 8 hours
= 89/400 × 8
= 1 39/50 hours
Answer:
4 days
Step-by-step explanation:
first convert 1/4 to eighths
2/8=1/4
to make 2/8 equal 7/8
you have to multiply by 4 for it to be 8/8
it cant be 7/8 because that would be three and a half days and they only read 1/4 each day
so it would take 4 days to finish
Answer:
I have provided an explanation on the attached picture. Good Luck.
The mixed number is 3 75/100, but you can reduce that to 3 3/4.3 as an integer.
Whenever a problem says "one number" and "another number" we can substitute x and y. for this we have x=2y+1 and xy=1. since we know the value of x (2y+1) we can substitute it for the other equation to get (2y+1)y=10. simplify to get 2y^2+y=10. from here you can do a few methods to solve this, but the simplest in my opinion is by factoring.
In order to factor it must be equal to 0, so we have 2y^2+y-10=0. We factor this and get y=5 (we also get y=-4 but it is an extraneous root). now we can plug that into either equation and find that x=2.
this means our two numbers are 5 and 2
