If f(x) varies directly with x and f(x) = 4 when x = 12, then what is the value of f(x) when x = 60?

ANTONII [103]

ANSWER

$f(60)=3\times60=180$

EXPLANATION
We were given that
$f(x)$
varies directly as
$x.$

We can write this mathematically as,

$f(x) \propto \: x.$

This implies that,

$f(x) = kx$
where k is the constant of variation.

$f(4)=4k$

This implies that,

$4k=12$

$k = 3$

The equation becomes

$f(x)=3x$

When $x=60$

$f(60)=3\times60=180$

If a globe rotates 150 degrees in 5 seconds, how many rotations does it make in 30 seconds? I got 900 seconds for my answer am I

Maksim231197 [3]

Start with a proportion, to get the number of degrees in 30 seconds:

   (150 degrees / 5 seconds) = ('D' degrees / 30 seconds) .

Cross multiply the proportion: (150 x 30) = 5 x D

   4,500 = 5 x D

Divide each side by 5 : 900 = D

The globe turns 900 degrees in 30 seconds.

How many rotations is that ?
Each rotation is 360 degrees.
So 900 degrees is
   (900 / 360) = <em>2.5 rotations</em> in 30 seconds.
