Because a percent is a fraction of 1/100 of a whole thing. for example a whole is 200 and we want to find the 37% of it, we would divide 200 over 100 (which is the percent of the whole thing) and the multiply it by 37 (that is the percentage of the part of the whole thing) and we get 74.
74=37% of 200
Answer: 1/23
Step-by-step explanation:
Subtract 8x from both sides of the equation
from both sides of the equation
-15x = 8x + 1
-15x- 8x = 8x + 1 - 8x
Simplify
-23x = 1
Divide both sides of the equation by the same term
-23x = 1
=
Simplify
x = 1/23
Answer:
See proof below
Step-by-step explanation:
In trigonometry identity
tan^2 theta = sin^2 theta /cos^2 theta
cot^2 theta = cos^2 theta/sin^2 theta
csc^2 theta = 1/sin^2 theta
Substitute into the expression
(sin^2 theta /cos^2 theta )+ (cos^2 theta/sin^2 theta)/1/sin^2 theta
= [sin^4theta + cos^4theta/cos^2 theta sin^2 theta]÷(1/sin^2 theta)
= 1/cos^2 theta sin^2 theta÷(1/sin^2 theta)
= 1/cos^2 theta sin^2 theta * sin^2 theta/1
= 1/cos^2theta
= sec^2theta (Proved!)
Answer:
$220
Step-by-step explanation:
5/01: Beg. inventory: 10 × $10 = $100
5/03: Add inventory: 10 × $12 = $120
5/08: Less inventory: (10 × $12) + (2 × $10) = $140
5/15: Add inventory: 10 × $14 = $140
5/31: End. inventory: (10 × $14) + (8 × $10) = $220
