PLZ HELP DUE TODAY 100 POINTS!!

ALRT let us see

Step-by-step explanation:

PART A: 4*3/8= 1.5 hours

1 hours and 30 minutes or 90 minutes or 1.5 hours which ever u like to write in

PART B:

1.5 hours+ 6 hours= 7.5 hours

7 hours and 30 minutes or 7.5 hours

PART C:

7.5/0.5= 15

15 half-hour sitting periods

this doesn't make sense lol

see explanation

step-by-step explanation:

since the sequence is geometric there is a common ratio r between consecutive terms, that is

r = 4 ÷ - 2 = - 2

r = - 8 ÷ 4 = - 2

r = 16 ÷ 8 = - 2

the next term - 13 must be incorrect as it should be - 32 for the sequence to be geometric.

the first 4 terms are therefore geometric with common ratio r = - 2
