6 holes in 24 mins.
1 hole in 4 mins.
54 × 4= 216
41 × 4= 164
216-164= 52
So it would take 52 more minutes.
List the factors:
21: 1, 3, 7, 21
40: 1, 2, 4, 5, 8, 10, 20, 40
They only have 1 in common.
So 1 is the greatest common factor.
when given the function f x 3x + 6 + f g x + 12 - 3 you have to find the values of M you want to play 3 m - 7 m squared minus one and then subtract that in after subtracting divide and that's so on and so on
Amount of the job done after 2 hours:
2(1/6 + 1/8)
2(4/24 + 3/24)
2(7/24)
7/12 (amount of job finished)
.
amount of job left to do:
1 - 7/12
12/12 - 7/12
5/12 (remaining)
.
Let x = time (hours) slower press takes to finish job
then
x(1/6) = 5/12
multiplying both sides by 6:
x = 5/12 *6
x = 5/2 hours
or
x = 2 hours and 30 minutes
The slower press (8-hour press), will take h 3 hours, 20 minutes to complete the job
