Intensity=k/(distance)² where k is a constant
8000=k/2²
8000=k/4
k=32000
If distance is 11 miles, Intensity=k/11²
=32000/121
=264.46units
≈264units
Its an area equation. Area is length times width.
So to start, he needs 50x80 square feet in his front yard, BUT THAT IS ONLY HALF OF THE PROBLEM. For the front yard he needs 4000 sq. feet. For the back, it is different. He needs 10x40÷2. To first simplify, we do the multiplication. This comes to 400÷2. then it is simply 200.
Now for the easy part. Take the 4000 and add 200. Answer? 4,200.
There's 5 1/8 cups of water left in the pitcher.
- 5 1/2 = 11/2
- 11/2 = 44/8
- 44/8 - 3/8 =41/8
- 41/8 = 5 1/8
