Answer: the base area of the prism is 6 cm^2
Step-by-step explanation:

The 1:3 ratio means that the distance from A to the point is 1/4 of the distance from A to B.
The difference of y-coordinates is 10-8 = 2. 1/4 of that is 2·1/4 = 1/2, so the point of interest will have y-coordinate 8 + 1/2 = 8 1/2. This apparently corresponds to the first selection:
... (6 1/2, 8 1/2)
3/x=15/40
solve for x
multiply both sides by x
3=15x/40
multiply both sides by 40
120=15x
dvide both sdies by 15
8=x
the answer is 8
or you could simplifyy 15/40 to get 3/8

Answer:
684 Hours.
Step-by-step explanation:
If the plane travelled that distance in 5 hours, then all you need to do is divide the distance by 5 to get the distance travelled in one hour. This is obviously presuming that the speed travelled was constant or that this is an average figure.
3420/5 = 684.
