Answer:
Tea plantations were established in Sri Lanka by a former European colonial power.
Explanation:
The answer is the letter B. Amount of restriction measured in inches of water. <span>The restriction measuring devices are used to extend the filter's useful life, that is, they maximize the filter's useful life, which significantly reduces maintenance costs.</span>
2W+2L=66
W=1/2L
2(1/2L)+2L=66
Simplifies to L+2L=66
Simplifies to 3L=66
Or L=22.
If W=1/2L, then W =1/2(22).
W=11.
To check our work, 2W+2L=66.
2(11)+2(22)=66.
22+44=66
66=66 Check.
