8 / 6.403 = 1.249...
nearest tenth = 1.2
The answer for the first one is 4 the sacend one is 49/2 the thirst one is 33223
A....if its wrong im sorry but i believe its a because you will do 4x4 and will get the sum of 16ft square
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 )
4(2x5 + 3) - 4(2) + 2(5).
4(13) - 18.
52-18 = 34.
