The high school band and chorus are putting on a spring concert. the two groups together want to perform no more than 15 songs and the concert has to be 60 minutes or less in length. each piece the band performs is about 5 minutes in length. each piece the chorus sings is about 3 minutes in length. which system of inequalities best represents the number of songs the band performs (x) and the number of longs the chorus performs (y) for the concert?

a) x+y≤15and5x+3y≤60

b) x+y≥15and5x+3y> 60

c) x+y≤60and5x+3y< 15

d) x+y≤15and5x+3y≥60

F(n + 1) = f(n) – 8. if f(1) = 100, what is f(6)?

Use the spider tool located on page 1 of this activity to draw a 12-pointed star for the new logo. (hint: if the spider rotates 360 degrees -- or 720 degrees or 1080 degrees -- she will be facing in the same direction in which she started. when the spider is done drawing, you want her to be facing in the same direction in which she started. she'll be making 12 rotations, all the same size, so each rotation must be some multiple of 360/12 = 30 degrees.) urgently. been stuck on this problem for around 45 minutes now.! it should be easy if you're smart enough
