For the explicit formulae, the final answers are boxed.
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: 1.22 years
Step-by-step explanation: see photos attached.
<span>Tax rate is 4.5 percent of the item cost
so if you buy shoes that cost 63.20 you have to pay 4.5 percent of this value as tax

then multiply it by the item cost.
Therefore, </span><span>63.20 x .045 = $2.84</span>
SINCE THEY ALL PAID EQUALLY, IT HAS TO BE A MULTIPLE OF 3. BY TRIAL AND ERROR, THE FIRST POSSIBLE MATCH IS 3.. SINCE 132 IS DIVISIBLE BY 11
