Answer:

Step-by-step explanation:

All of the right triangles are similar. This means ...

long side / short side = x/2 = 25/x

Multiplying by 2x gives ...

x² = 25·2

x = (√25)(√2)

x = 5√2

_____

Additional comment

The "geometric mean" of 'a' and 'b' is √(ab). With this in mind, you can see that x is the geometric mean of the lengths 2 and 25. This is always true for this right-triangle geometry.

There are two other geometric mean relations in this geometry, having to do with the other possible ratios of sides. In effect, the length of a segment that touches the hypotenuse (longest side) of the triangle is the geometric mean of the two segments of the hypotenuse it touches.

Left side = √(2·27) = 3√6

Bottom side = √(25·27) = 15√3

What percent of the 2019 world population lives in Canada? Round the percentage to three decimal places.

dimaraw [331]

0.486 % of world population lives in canada

Solution:

From given,

World population = 7691 million

Canada population = 37.4 million

We have to find the percent of world population lives in canada

Let "x" be the percent of world population lives in canada

Therefore, from question,

x % of world population = canada population

x % of 7691 = 37.4

Solve the above equation for "x"

$x \% \times 7691 = 37.4\\\\\frac{x}{100} \times 7691 = 37.4\\\\7691x = 3740\\\\Divide\ both\ sides\ by\ 7691\\\\x = \frac{3740}{7691}\\\\x = 0.486$

Thus 0.486 % of world population lives in canada
