What is the difference between an approximate answer and exact answer

An example would be  1/3  as an exact answer  and 0.33 as an approximate answer because 1/3 = 0.333  - a recurring decimal where there are an infinite number of 3's. 0.33 would be correct to the nearest hundredth.

Radicals are exact answers :- like  √2 , √5 .  Approximate value for √2 is 1.414

Approximate means about, and exact means, spot on, not approximate, like the exact answer of 3+3 is 6 hope it helps!!

First, think of what you know. you know that the number t the end of the equation will need to be subtracted because it is the money he lost from buying the lawn mower. and your first two weeks have negative profit, so that tells you that c and d are wrong. now you can plug any of the weeks into a and b to see which one works. i'll start with plugging week 1 into a.this isn't right because it says your answer for week one should be -90.so now we need to try the same thing with b.this one got you the right answer, (sometimes if you only check with one of the weeks multiple will work so you need to check with more of the weeks, but it worked out fine here)this means that b is the correct answer.let me know if you need more clarification. i hope this : )
