mark has to walk the dog every other day has to feed the cat every 4 days and has to change the water in the fish tank every 6 days if he starts all of his chores today when is the next time he will have to do all three chores on the same day?

the 12th day

Step-by-step explanation:

Make a graph of all the chores and then find the first common number between all three.

Dog 2 4 6 8 10 12 14 16

Cat 4 8 12 16 20

Fish 6 12 1824

since the airplane is moving with constant speed then the distance travelled can be calculated by x=u*t

in km/h would be:

x=640*3.5=2.240 km

in m/s would be:

u=640 km/h= 640.000 m/h =640.000/ 3600 m/s =177.8 m/s

t= 3.5 h= 3.5 * 3600 s=12.600 s

then x=u*t= 177.8*12.600= 2.240.280 m

0/5 is 0, 2/0 is undefined, and 0/0 is indeterminate.
