Halla la medida del lado de un cuadrado cuya diagonal es de 14 cm

Answers

Answer:

The length side of the square is $7√(2)\ cm$

Step-by-step explanation:

The question in English is

Find the measure of the side of a square whose diagonal is 14 cmd

Let

d ----> the diagonal of a square in cm

b ---> the length side of a square in cm

we know that

Applying the Pythagorean Theorem

see the attached figure to better understand the problem

$d^2=b^2+b^2$

$d^2=2b^2$

we have

$d=14\ cm$

substitute the given value

$14^2=2b^2$

solve for b

$196=2b^2$

$98=b^2$

take square root both sides

$b=√(98)\ cm$

simplify

$b=7√(2)\ cm$

How do i turn 44.4% as a ratio?

Answers

$a=44.4\%x\nb=(100\%-44.4\%)x=55.6\%x\n \n (a)/(b) = (44.4\%x)/(55.6\%x) = (44.4)/(55.6) = (444)/(556) = (111\cdot4)/(139\cdot4)= (111)/(139)$

100% ---- 44.4%= 55.6% and 44.4% / 55.6% = 444/ 556= 111/139
