Answer:

You would need to use the Pythagorean Theorem

Step-by-step explanation:

First, you would want to take the Hypotenuse of 3 and square. Do the same for the 2.25. After that, you want to put in a calculator (Desmos Graphing Calculator) √3²-2.25² adn get the answer for the line of C and D (-2.06). After that, you do the same but on the other side: Take the Hypotenuse of 4 and the -2.06 and form it into √4² -2.06². Your final answer would be...

x = 3.43

Answer:

Both triangles are right triangles because the angle d is 90 degrees in both sides

3 ^ 2 - 2.25^2 = 1.98

4^2 - 1.98^2 = 3.48

x = 3.48

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;

$\sqrt{xy} = 3$

or

$xy = 9 - - - (2)$

l

and

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

or

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

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

$\frac{1}{9}$
