It is 7

12 is already in the simplest form. It can be written as 0.583333 in decimal form (rounded to 6 decimal places).

Steps to simplifying fractionsFind the GCD (or HCF) of numerator and denominator
GCD of 7 and 12 is 1Divide both the numerator and denominator by the GCD
7 ÷ 112 ÷ 1Reduced fraction: 712

ELEN [110]

Answer:

The region with the highest population density is Binky Lee

The region with the lowest population density is ChesLen

Step-by-step explanation:

The population density is the total number of people per unit of land area.

Population density = Total population / land area

Beer Creek = 12,624/3,412

= 3.6998827667057

Approximately, 3.7

Binky Lee = 462/112

= 4.125

Approximately, 4.1

ChesLen = 3,537/1,263

= 2.8004750593824

Approximately, 2.8

Crow's nest = 2,142/612

= 3.5

The region with the highest population density is Binky Lee

The region with the lowest population density is ChesLen

Find dy/dx of y=csc(square root of x)

Vitek1552 [10]

Answer:

$y' = -\dfrac{\cot x \csc x}{2 \sqrt{x}}$

Step-by-step explanation:

y = csc x

y' = -cot x csc x

$y = \csc \sqrt{x}$

$y' = \dfrac{d}{dx} [\csc \sqrt{x}]$

$y' = (-\cot x \csc x) \dfrac{d}{dx} \sqrt{x}$

$y' = (-\cot x \csc x) \dfrac{d}{dx} x^{\frac{1}{2}}$

$y' = (-\cot x \csc x) \dfrac{1}{2} x^{-\frac{1}{2}}$

$y' = -\dfrac{\cot x \csc x}{2 \sqrt{x}}$

2 parakeets + 4 canarys + 5 goldfish + 1 turtle = 12 pets
