Answer:
179.159
Step-by-step explanation:
Given the sequence :
50, 60, 72,..
The sequence given is a geometric sequence :
For a geometric sequence ;
ar^(n - 1)
a = first term
r = a2 / a1 = 60 / 50 = 1.2
The 8th term ; n =8
a8 = ar^(n - 1)
a8 = 50*1.2^(8 - 1)
a8 = 50*1.2^7
a8 = 50*3.5831808
a8 = 179.15904
a8 = 179.159 (nearest thousandth )
Is it .236 cuz then you would round it to,.24
20% also equals 1/5, right?
So in order to find the total number of turtle nests, just find 5/5, or multiply 15 by 5.
15 x 5 = 75
There were 75 total nests
75.09 = seventy- five and nine-hundredths
