Answer:
Volume= 180
Step-by-step explanation:
The formula for finding the volume of a triangular prism is V= LWH divided by 2. L=Length W=Width H= Height So (12)(6)(50)= 360 divided by 2 is 180.
For that answer i got 3 -2/120 but I'm not sure about it
Answer:
the solution is (3,4) (the second one)
Step-by-step explanation:
Answer: The equations are
6x - 6y = 9
4x + 4y = 9
Step-by-step explanation:
Let x represent the speed of the row boat in still water.
Let y represent the speed of the current.
Dana can travel 9 miles in her rowboat in 6 hours against the current. This means that the total speed at which she travelled is
(x - y) miles per hour.
Distance = speed × time
Distance travelled against the current is expressed as
9 = 6(x - y)
6x - 6y = 9
With the current, it takes 4 hours to row the same distance. This means that the total speed at which she travelled is
(x + y) miles per hour.
Distance travelled with the current is expressed as
9 = 4(x + y)
4x + 4y = 9
