A, b and c start at the same time in the same direction to run around a circular stadium. a completes a round in 252 seconds, b in 308 seconds and c in 198 seconds, all starting at the same point. after what time will they again at the starting point ? a. 36 minutes 22 secondsb. 46 minutes 22 secondsc. 36 minutes 12 secondsd. 46 minutes 12 seconds

D. 46 minutes 12 seconds

Step-by-step explanation:

To find the answer, we need to calculate the least common multiple of 252,308 and 198

252=××7

308=×7×11

198=2××11

Then least common multiple is

××7×11=2772 seconds

2772 = 46×60 + 12

Therefore 2772 secondsis equal to 46 minutes 12 seconds.

i think is g(1)=-1.

hope that i can

the answer would be 1 1/72

step-by-step explanation:

you can rewrite the equation by separating the parts and then solving individually:

10-9=1

1/8 - 1/9=

find l c d and then combine:

1 1/72
