There are 12 months in a year.
Divide 9 by 12 then multiply by 100 to get the percentage.
9/12 = 0.75 x 100 = 75%
Answer: 75%
Step-by-step explanation:
Add 75 to 12.55. the answer would be 87.55.
100+105=205
205-87.55=117.45
Tan(x)= sin(x)/cos(x), therefore, substitute sin(x)/cos(x) in the expression:
=(cos(x)(sin(x)/cos(x))-1)/cos^2(x)
simplify the 2 cos(x):
=(sin(x)-1)/cos^2(x)
Sin^2(x)+ cos^2(x)=1, sin^2(x)-1=- cos^2(x), substitute in the expression:
= -cos^2(x)/cos^2(x)= -1
