The answer to ur question is 20 degree angles cause each dot is 5 degrees so that would equal 20 after you split them up
-1, 5/2
And in decimal form 1, 2.5
<u>1.03*10^{6}>9.8*10^{5</u>
Answer:
4.01*10³<5*10^(-5)false
3.9*10^5<8.06*10^{-7}false
1.03*10^{6}>9.8*10^{5}true
7.8*10^{2}>2.1*10^{3}false
Sn = n/2(a + l); where sn is the sum of n terms, n is the number of terms, a is the first term and l is the last term.
1390 = n/2(3 + 136)
2780 = 139n
n = 2780/139 = 20
2nd term = 3 + 20 = 23
3rd term = 23 + 20 = 43
First three terms = 3, 23, 43
option b.
