Answer:
5.4 is rational. 5.4 divide by 2 is 2.45 5.3 and 5 3 are irrational, as it cant be divided easily
I'm not 100% sure but this is how I would try.
If you don't get a better answer, check this w/your teacher.
x/100 *90,000 = 1200
90,000x = 120,000
x = 1.3% tax percentage
1.3/100x = 2200
1.3x = 220,000
x = $169,230.77 assessed value
Represent these consecutive numbers (assuming that they are all integers):
x
x+1
x+2
x+3
x+4
x+5
and so on
x+8
x+9 is the tenth number. x+9 = 10, so x = 9.
Think of it this way: there are 10 consecutive numbers, and the last one is 10.
Working backwards, we get the sequence 10, 9, ... 3, 2, 1.
The sum of such an arith sequence is equal to the count of the numbers times the average of the first and last terms:
sum here = 10(1+10)/2 = 5(11) = 55 (answer)
X= 15/22. Hope this helps :)
I assume you mean divide using the conjugate to rationalize the denominator and express the result in standard rectangular form.
