Answer:
20%
Step-by-step explanation:
Let x represent the initial value of the stock at the beginning of 2006. And y the value at the end of 2006.
When it went up by 25% in 2006;
y = x + 25% of x = x + 0.25x = 1.25x
For the value to go back to the original price, it has to decrease from y to x;
y = 1.25x
The percentage decrease from y to x is;
= (y-x)/y × 100%
Substituting the values;
= (1.25x -x)/1.25x × 100%
= 0.25x/1.25x × 100%
= 0.2 × 100%
= 20%
Therefore, it will have to go down 20%

Answer: C
The side of the triangle is 13 inches
Side of square. 6 inches
X= side of square
4x+15 =3(x+7)
4x+15=3x+21
x=6
6+7= 13
Perím square 6x4= 24
Perim triangle 13x3=39
39-24=15
Answer:
The answer to your question is the first choice
Step-by-step explanation:
Data
Force = 465 N
bearing = 19°
Process
1.- Find the components using trigonometric functions
To find the horizontal component use cosine
To find the vertical component use sine
cos Ф = x/F sin Ф = y/F
Substitution
cos 19 = x/465 sin 19 = y/465
x = 465 cos 19 y = 465 sin 19
x = 439 N y = 151.39 N
2.- Rounding to the nearest number
Horizontal component = 440N
Vertical component = 151 N
