The metric system is not a unit, so that's already ruled out. A millimeter is much much smaller than an inch and a centimeter is just a little bit bigger than an mm. So, that leaves us with options C and D. A meter is also way too small for measuring the size between two cities. So, your answer is D, kilometer.
120(60)
120 ÷ 100 = 1.2
120 / 100 = 1.2
Take off the "60" and multiply it by 1.2
1.2(60) = 72, right ?
So, therefore your answer would have to be : 72
Answer:
400 800 1200 1600 2000 is anwser
Given:
2,000 square kilometers
decreases by 6% per year
12 years.
f(x) = P(1+r)^x
The fact that the term decreases is used, (1+r) will become (1-r)
f(12) = 2,000(1-0.06)^12
f(12) = 2,000(0.94)^12
f(12) = 2,000(0.4759)
f(12) = 951.80
Answer is:
f(x) = 2,000(0.94)^x, 952 square kilometers.
