1. Always true. 1+1=2
2. Always true. 1+e is irrational.
3. Sometimes true. e + (-e) = 0 which is rational.
4. Always true. 1*1 = 1
5. Sometimes true. 0*e = 0 which is rational.
6. Sometimes true. Sqrt(2) * sqrt(2) = 2 which is rational.
The question asked for an example to support your answer, but none of the answers can be proven with just one example. The answers which are sometimes true need 2 examples to be proven, and the answers which are always true cannot be proven by example.
"Simple interest" means the interest goes into a separate bucket, and
it just waits there for you to come and get it. It <em><u>doesn't</u></em> get added to the
amount in the account, so next year, you don't get interest on the interest.
4 percent of $2000 is (0.04 x 2000) = $80 .
That's how much interest you get each year.
At the end of 4 years, you have (4 x $80) = <u>$320</u> in the interest bucket.
(And of course, you still have the original $2000 in the account.)
Answer:
ummmmmmmmmm this makes no sense
Step-by-step explanation:
The little square means a right angle which is equal to 90 degrees.
X + 30 = 90
X = 60 degrees
