Perimeter = Sum of the sides

Thus ;

$Perimeter = (0.5x + 9) + ( 3x) + ( - 3.4x - 25) \\$

$Perimeter = - 3.4x + 3x + 0.5x - 25 + 9 \\$

Collect like terms

$Perimeter = 0.1x - 16$

Answer:

perimeter = A + B + C

perimeter = 0.5x + 9 + 3x + (-3.4x - 25)

perimeter = 0.5x + 3x -3.4x + 9 - 25

perimeter = 3.5x - 3.4x + 9 - 25

perimeter = 0.1x + 9 - 25

perimeter = 0.1x - 16

The observation deck is about 20 m above sea level. From the observation deck, the angle of depression of the boat is 6 degrees.

Leno4ka [110]

θ\ 6 degrees
    \
\ so the θ= 180-90-6 =84 degrees so we need to find x
20m   \ tan (84)=x/20
  ____  \ x=20 tan(84)
x x=190.287

What is the exact volume of the cone with a radius of 7in and a height of 4in use 3.14 for π

vfiekz [6]

Answer:

The exact volume of the cone is $\frac{196}{3}\pi\ in^{3}$

Step-by-step explanation:

we know that

The volume of the cone is equal to

$V=\frac{1}{3}\pi r^{2}h$

we have

$r=7\ in$

$h=4\ in$

substitute the values

$V=\frac{1}{3}\pi (7^{2})(4)=\frac{196}{3}\pi\ in^{3}$
