the common ratio in geometric series is 0.5 and the first term is 256. what is the sum of the first 6 terms in the series?
melisa1 [442]

Answer:

501.76

Step-by-step explanation:

common ratio r = 0.5

first term a = 256

sum of G.p = Sn= a( r^n -1)/r-1

sum of the first 6 terms =

S6 = 256( 0.5^6 - 1)/ 0.5 - 1

= 256( 0.0156 - 1)/-0.5

= 256( -0.98)/-0.5

= - 250.88/-0.5

S6 = 501.76

Answer:

  1080 minutes

Step-by-step explanation:

The greatest common factor (GCF) of the two times is 15 minutes, so their least common multiple is (120×135)/15 = 1080 minutes.

In that time, Kayla will have watched 9 shows, and Josh will have watched 8.

It will be 1080 minutes before they start again at the same time.
