$\frac{6}{15}$ = $\frac{2}{c}$ Cross multiply (6 x c and 15 x 2)
6c = 30 Divide both sides by 6
c = 5

It's a proportion.
6*c=15*2
6c=30
6/6=30/6
c=5

Answer:

$\frac{1}{2}$

Step-by-step explanation:

sin( $cos^{-1}$ $\frac{\sqrt{3} }{2}$ )

using the sides of the 30- 60- 90 triangle

with legs 1, $\sqrt{3}$ and hypotenuse 2 , then

$cos^{-1}$ $\frac{\sqrt{3} }{2}$ = 30° and

sin30° = $\frac{1}{2}$

andre [41]

The answer is 12.8 cm³

<span>The volume ( v) of a gas in a container at a constant temperature varies inversely as the pressure (p):
v = k/p
p * v = k (k - constant)

p1v1 = k
p2v2 = k
So, p1v1 = p2v2

v1 = 24 cm</span>³
p1 = 16 lb
v2 = ?
p2 = 30 lb

24 * 16 = x * 30
384 = x * 30
x = 384 / 30
x = 12.8 cm³
