Answer:
200 bags are needed
Step-by-step explanation:
First let us determine the area of the corn field:
Shape of cornfield = square
Area of a square = Length × Length
where: Length = 100 yards
∴ Area = 100 × 100 = 10,000 square yards
1 bag of fertilizer is needed to cover 50 square yards:
50 square yards = 1 bag of fertilizer
![\therefore 1 \ square\ yard\ = \frac{1}{50}\ bag\\10,000\ square\ yards\ =\ \frac{1}{50} \times 10,000 = \frac{10l000}{50} \\ = 200 bags](https://tex.z-dn.net/?f=%5Ctherefore%201%20%5C%20square%5C%20yard%5C%20%3D%20%5Cfrac%7B1%7D%7B50%7D%5C%20bag%5C%5C10%2C000%5C%20square%5C%20yards%5C%20%3D%5C%20%5Cfrac%7B1%7D%7B50%7D%20%5Ctimes%2010%2C000%20%3D%20%5Cfrac%7B10l000%7D%7B50%7D%20%5C%5C%20%3D%20200%20bags)
Hence, 200 bags are needed.
Answer:
(-4,4)
Step-by-step explanation:
-5x-10y=-20
10x+10y=0
divide both sides by 2
-5x-10y=-20
5x+5y=0
that makes
-5y=-20
divide both sides by -5
y=4
now substitute 4 for y
10x+10 x 4=0
multiply
10x+40=0
subtract
10x=-40
divide
x=-4

Answer:
Population management is important due to the fact that humans rely on different types of animals for food that if we populate to much that we could all run out of food because say if there are 30 humans and 5 pigs even if they both multiply there well still not be enough in the long run. Which throws the balance over nature off. So if we keep on populating we are practically killing are selves, population management is essential if you do not want the human race to die out.
