All of the following are rational except 0, - 2/5, 0.125, 3.

0, - 2/5, 0.125, are except 3.14159....

Step-by-step explanation:

Given  : Numbers  0, - 2/5, 0.125, 3.14159...

To find: all of the following are rational except .

Solution : We have given that

0, - 2/5, 0.125, 3.14159...

Rational numbers : Number can be expressed as and countable.

Then  0, - 2/5, 0.125, are countable .

3.14159... are uncountable.

So, 3.14159... is irrational number.

Therefore, 0, - 2/5, 0.125, are except 3.14159....

$53.50

step-by-step explanation:

you have to subtract the amount of money chuck earned ($72.50) by the cost of the gas for the mower ($11.25) and the new string for the trimmer he bought ($7.75).

72.50-11.25=61.25

and then subtract $61.25 by the second thing he bought (the new string for the trimmer)

61.25-7.75=53.5

so in total it's $53.50 (53 dollars and 50 cents)
