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.
This is the answer 3.4392.55*10^4
One way: log(A)-log(B) = log(A/B) right?
So, log( x^2-9/(x+3))
Now x^2-9 = (x+3)*(x-3), and x^2-9/(x+3) = x-3,
so log(x^2-9)-log(x+3) = log(x-3),
Indeed for all x but for x = -3, but probably no one asks you about that detail?
Answer: =160
Step-by-step explanation:
Volume of prism= 1 1/3 x 5/6 x 2/3 = 4/3 x 5/6 x 2/3 = 20/27
Volume of cube= 1/6 x 1/6 x 1/6 = 1/216
Number Cubes packed in rectangular prism= 20/27 / 1/216 = 160
