This is just simple Pythagorean’s theorem. a^2 + b^2 = c^2
Number 2:
5^2 + x^2 = 10^2
25 + x^2 = 100
x^2 = 75
x = sqrt 75 = 5*sqrt(3)
Number 3:
4^2 + x^2 = 7^2
16 + x^2 = 49
x^2 = 33
x = sqrt 33
are you asking for the 9th term or the 10th term?
*expanded form: 6/10 + 3/100 + 2/1000 (that is not division those r fractions!)
*written: six hundred thirty-two thousandTHS
always put "ths" when it is after a decimal point.
Answer:
15% off
Step-by-step explanation:
We know we paid $25.50 of the original $30. We can divide these two numbers 
. This is means we paid 85% of the original price. The discount percentage is the remaining percentage from 85 to 100 which is 15. The pants were 15% off.
