Ur basically looking for the common multiple of the numbers 8,9,12,and 15.
LCM of these numbers is 360.
so 360 minutes = (360/60) = 6 hrs
and 6 hrs from 3 p.m. would be : 9 p.m. <== ur answer
Where are the triangles so I can compare to find the triangle congruence?
I'm assuming there is probably a graph that goes with this problem so here is all the info I can give you with the four choices:
If it is -1/3, the line will go DOWN 1, over 3 (just count on the graph)
If it is 3, the line will go UP 3, over 1
If it is 1/3, the line will go UP 1, over 3
And if it it -3, it will go DOWN 3, over 1
(If the slope is 3 or -3, it would be quite steep compared to a slope of 1/3 or -1/3)
Hope that helps!
For every four white balls taken out one black ball is taken out so it would be the 52 white ball
7/10 you just get the decimal form of the numbers and find a simple decimal between them, which was 7, and put it over 10 so you get 7/10
