Old mcdonald has 100 chickens and goats in the barnyard. altogether, there are 284 feet. how many chickens and how many goats are in the barnyard?

58 chickens, 42 goats

Step-by-step explanation:

there are a total of 100 chickens and goats

c + g = 100c = 100 - g

there are 284 feetchickens have 2 feet and goats have 4 feet

2c + 4g = 284

2(100 - g) + 4g = 284

200 - 2g + 4g = 284

-2g + 4g = 284 - 200

2g = 84

g = 84/2

g = 42 < goats

c + g = 100

c + 42 = 100

c = 100 - 42

c = 58 < chickens

so a parallelogram is just like a square base times height. multiply 40 and 39 to get 1560 inches.

a triangle is base times height divided by two. so multiply 7.9 and 5 and then divide it by 2 to get 19.75inches.

the kite can be split into two separate triangles and added together to get the total area. 30 x 4 /2 which equals 60. make sure to double it for the two triangles making 120.

i got 10.28 but that rounds up to 10.3
