In my garden there is a cage that contains both chickens and dogs. If there is a total of 30 eyes and 44 feet, how many of chick

gregori [183]

Answer:

This is a trial and error problem

we can divide 30 eyes by 2 eyes on each animals to know that there is 15 animals

15 animals now make a random guess

Find out the difference of feet. 1 dog has 4 feet - 2 chicken feet = 2 feet increase or decrease so if we need to increase by 2 we add 1 dog and if we need to subtract to then we add 1 chicken

11 dogs and 4 chickens

that is 44 feet + 8 feet = 52 feet

52 - 44 feet needed = 8 feet

8 / 2 feet decrease = 4 more chickens needed

11 - 4 (subtracting 4 dogs off)= 7

4 + 4 (replacing the dogs with chickens)= 8

7 dogs and 8 chickens

7 x 4 = 28

8 x 2 = 16

28 + 16 = 44

7 dogs and 8 chickens

Answer:

Step-by-step explanation:

area of hexagon = $\frac{3*\sqrt{3} }{2}$ * $a^{2}$ where a = length of 1 side

this hexagon is made of 6 equivalent triangle

consider ABC triangle

let AC length be x

AB = 2 * AC = 2x = a

$bc^{2} = ab^{2} - ac^{2} \\(4\sqrt{3})^{2} =(2x)^{2} - x^{2} \\48=3*x^{2}\\ 16=x^{2} \\x=4$

Hence a = 8

hence area of hexagon = $\frac{3*\sqrt{3} }{2}$ * $a^{2}$ = $\frac{3*\sqrt{3} }{2}$ * $8^{2}$ = 166.27 m2
