Sarah watched the scarecrow scare away 2 crows on monday 5 crows on tuesday 11 crows on wednesday and 23 crows on thursday sarah notice a pattern forming can you predict how many crows could be scared away on friday saturday and sunday

I got 47 because...

Tn = Tn-1 + 3×2^(n -1)

Using the above formula,

T2 = 2 + 3×2^(1-1) = 2 + 3×2^0 = 2 + 3 = 5

T3 = 5+ 3×2^(2-1) = 5 + 6 = 11

T4 = 11 + 3×2^(3-1) = 11 + 12 = 23

T5 = 23 + 3×2^(4-1) = 23 + 24 = 47

he spend 5.1 minutes chatting with his friends

step-by-step explanation:

2/5+1/2=9/10

6/1-9/10=5 1/10

1)is not similar since corresponding sides are not in the same ratio

2)are similar since corresponding sides are in the same ratio and corresponding angles are equal

hope it will
