The '40 years' is not part of the question. It's just there to prove that
'2% each year' has been the experience for the past 40 years, so it's
a good number to use for the rate of growth, past or future.
So, at any number of years 'Q' after the beginning of "this period",
the population was or will be
Pop = (220,000) (1.02)^Q power.
(This equation is familiar from all of the bank-interest problems
the student has done in past math classes.)
In 10 years after the beginning of "this period",
Pop = (220,000) (1.02)¹⁰ = <em>243,800 </em>(or any reasonably close number)
12 blue marbles for 15 white marbles because you multiply 5*3 so multiply 4*3 to get answer
<span>198 square feet should be your answer :)</span>
Answer a:
Figure 4 = 5 blocks up, 5 blocks right
Figure 5 = 6 blocks up, 5 blocks right
Answer b: Grows 2 blocks each time, 1 blocks at the top and 1 blocks on the right.
Answer c: Since you add 2 blocks each time, you do the opposite so you subtract 2 blocks. The answer will be 1 block.
