Answer:
First = 1000
Second = 10,000
Step-by-step explanation:
Given the following :
Amount invested = $11,000
A portion earns 2 1/2 % interest per year
The rest earns a rate of 2% per year
Total Interst earned after a year = $255
Amount invested at each rate
Let amount invested at 2 1/2% = a
Amount invested at 2% = 11,000 - a
Simple interest = principal * rate * time
First investment :
a * 5/2% * 1
Second :
(11000 - a) * 2%
Firat investment + second = $225
a * 0.025 + (11000 - a) * 0.02 = 225
0.025a + 220 - 0.02a = 225
0.005a = 225 - 220
0.005a = 5
a = 5 / 0.005
a = 1000
Amount in first investment = 1000
Second investment = 11000 - 1000 = 10,000

Step-by-step explanation:
I'll guess the answer is <em>you can tell that pi is an irrational because it has a </em>non-terminating yet non-repeating decimal representation.<em>
</em>
Of course it's not clear how we tell this. We can't know for sure just by looking at the first trillion digits we've figured out whether it repeats or not. Someone told us it didn't, that's really how we know.
