Which is the correct calculation for the volume of the prism??A 3 + 5 + 4 = 12 Units cubed
B 3(4) + 5 = 17 Units cubed
C 3(4) = 12 Units cubed
D 3(5)(4) = 60 Units cubed

choice b is correct

step-by-step explanation:

we have been given the following system of linear inequalities;

we are required to graphically determine the solution to these system of inequalities. using a graphing tool, the solution is as shown in the attachment below;

54 km / hours

step-by-step explanation:

we need to convert seconds to hours

60 seconds = 1 minutes

60 minutes = 1hour

15 m         60 second   60 minutes

  * *         = 54000 meters/ hour

second     1 minute             1 hour

now we need to convert meters to km

1000 m = 1 km

54000 m       1 km

*   = 54 km / hours

hour               1000m
