The ratio of the geometric mean and arithmetic mean of two numbers is 3:5, find the ratio of the smaller number to the larger nu

IgorC [24]

Answer:

$\frac{1}{9}$

Step-by-step explanation:

Let the numbers be x,y, where x>y

The geometric mean is

$\sqrt{xy}$

The Arithmetic mean is

$\frac{x + y}{2}$

The ratio of the geometric mean and arithmetic mean of two numbers is 3:5.

$\frac{ \sqrt{xy} }{ \frac{x + y}{2} } = \frac{3}{5}$

We can write the equation;

$\sqrt{xy} = 3$

$xy = 9 - - - (2)$

and

$\frac{x + y}{2} = 5$

$x + y = 10 - - - (2)$

Make y the subject in equation 2

$y = 10 - x - - - (3)$

Put equation 3 in 1

$x(10 - x) = 9$

$10x - {x}^{2} = 9$

${x}^{2} - 10x + 9 = 0$

$(x - 9)(x - 1) = 0$

$x =1 \: or \: 9$

When x=1, y=10-1=9

When x=9, y=10-9=1

Therefore x=9, and y=1

The ratio of the smaller number to the larger number is

$\frac{1}{9}$

Solve the formula for the indicated variable. k=g-d/c for g

Murrr4er [49]

Just like any other variable, we complete the same process

$k = g - \frac{d}{c} \\ k + \frac{d}{c} = g \\ \frac{kc + d}{c} = g \\$
Now we can test it, let's say k=4, d=6, and c=2, let's find the value of g
$4 = g - \frac{6}{2} \\ 4 + 3 = g \\ 7= g$

OR

$\frac{kc + d}{c} = g \\ \\ \frac{(4 \times 2) + (6)}{(2)} = g \\ \frac{14}{2} = g \\ g = 7$
