If f(x) varies directly with x and f(x) = 48 when x = 8 find the value of f(x) when x = 2

const2013 [10]

Here, f(x) = kx

k = f(x)/x
k = 48/8
k = 6

So, when x = 2,
f(x) = 6 * 2
z = 12

In short, Your Answer would be: 12

Hope this helps!

7.5% of what number is equal to 85% of 200?

Ksivusya [100]

Solving:

$\frac{7.5}{100} *x = \frac{85}{100} * 200$

$\frac{7.5x}{\diagup\!\!\!\!\!\!\!\!100} = \frac{17000}{\diagup\!\!\!\!\!\!\!\!100}$
$7.5x = 17000$
$x = \frac{17000}{7.5}$
$x = 2266.6666... \:\to \boxed{\boxed{x \approx 2266.67}}\end{array}}\qquad\quad\checkmark$

What is the probability that it is not blue?

ladessa [460]

This is actually easy, because you just have to add up the 25 +15 and that would get you 40. Then you would have to add 20 to the 40 and that would be 60, so that would make 40/60 chance that she wouldn't get blue.

And if you need it in a percentage, then you can just convert this into a percentage which would be, 66.666666666667%, also known as 66.67%
