Answer:
3.14 d greater-than 50
(i also need help with one of my questions >~<)
Step-by-step explanation:
Since the circumference of a circle is approximately 3.14 times the length of its diameter, mathematically speaking:
C = 3.14d
That expression must be greater (>) than 50:
3.14 d > 50
So, the correct option is; 3.14 d greater-than 50
The greatest number of groups would probably be 7 because:
21+7 = 28
28: 1, 2, 4, 7, 14
28/2 = 14
Half of 28 is 14 which means that each group will have 2 marbles. I am not sure if I'm correct, but I hope this helps! :)
80/5=16
16*3=48
80-48=32
32\5=6.4

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
