Answer:
Number of cows is 23
Number of chickens is 46
Step-by-step explanation:
Let's assume
number of cows =x
we are given
Mr.Yan has almost as twice as many chickens and cows
so,
Number of chickens =2x
We know that
Number of legs in a cow =4
Number of legs in a chicken =2
now, we can set up equation
![4\times x+2\times 2x=184](https://tex.z-dn.net/?f=4%5Ctimes%20x%2B2%5Ctimes%202x%3D184)
![4x+4x=184](https://tex.z-dn.net/?f=4x%2B4x%3D184)
![8x=184](https://tex.z-dn.net/?f=8x%3D184)
![x=23](https://tex.z-dn.net/?f=x%3D23)
So,
Number of cows =23
Number of chickens is
![=2\times 23=46](https://tex.z-dn.net/?f=%3D2%5Ctimes%2023%3D46)

Answer:
36 units
Step-by-step explanation:
Split the parallelogram into 3 shapes. Two right triangles and one rectangle.
Find the length of all the sides.
Triangle one: Triangle two:
Leg 1: 8 a^2+b^2=c^2 Leg 1: 8 a^2+b^2=c^2
Leg 2: 6 8^2 + 6^2 = c^2 Leg 2: 6 8^2 + 6^2 = c^2
Hypotenuse: ? 64 + 36 = c^2 Hypotenuse: ? 64 + 36 = c^2
100=c^2 100=c^2
c=10 c=10
Hypotenuse One: 10 units
Hypotenuse Two: 10 units
Base One Length: 8 units
Base Two Length: 8 units
Add all these numbers up and your answer would be 36 units.
Puppies = 4 feet
Parrots = 2 feet
15 heads = 15 animals
Assumed all Parrots,
15 x 2 = 30 feet
50 - 30 = 20
There are 20 extra feet which must belong to puppies' extra 2 feet each
20 ÷ 2 = 10
There are 10 puppies
15 - 10 = 5
There are 5 parrots
Check:
10 x 4 + 5 x 2 = 50 feet (Correct)
