Answer:
the common ratio is 6
Step-by-step explanation:
because 4 times 6 is 24
24 times 6 is 144
144 times 6 is 864
From the 8th to the 13th there are five numbers, and the difference between the 8th and the 13th is 20-12.5=7.5, so the difference between two neighboring number is 7.5÷5=1.5
from the 13th and the 25th there are 12 numbers, so the total difference is 12*1.5=18
so the 25th term is 20+18=38
The answer is B 36 because the chance of you grabbing a white or black is 12/15 meaning if you pulled 15 marbles, most likely 12 of them are white or black. so, because 15 goes into 45 3 times, you multiply 12/15 by 3 getting 36/ 45 meaning you will mostly pull 26 black or white marbles.
c = 150 -8s
Step-by-step explanation:
Each "snack" was 8 pieces of candy, and there were 18 of them (plus 6 candies) to start with. Hence the starting number was ...
... 18×8 +6 = 144 +6 = 150
Each snack reduced that number by 8, so the candies remaining are
c = 150 -8s
