At a school concert the orchestra plays 8 songs that are 4.25 min long and 3 songs that are twice as long as each of the others. how long is the concert ?

Total time of the concert  = 59.5 min =  59 minute 30 seconds

Explanation:

 At a school concert the orchestra plays 8 songs that are 4.25 min and 3 songs that are twice as long as each of the others.

 Total length of 8 songs = 4.25*8 = 34 min

 Length of 3 songs = 2*4.25 = 8.5 min

 Total length of 3 songs = 3* 8.5 = 25.5 min

Total time of the concert = 34 + 25.5 = 59.5 min =  59 minute 30 seconds

answer: it is d

step-by-step explanation:

step-by-step explanation:

a cube has 6 sides

the probability of getting 5 on the first cube is 1/6 since only one side of the cube has 5 on it.

there are 3 sides of the cube with even number on it [2,4,6]

therefore the probability of getting even number is 3/6

for both events to happen together, the probability would be

1/6 x 3/6 = 12/36

which simplifies to 1/12
