Step-by-step explanation:
45:15=3:1 not 1:3
Answer:
You need 10 of those numbers to be whole numbers, decimals, or fractions (THESE ARE RATIONAL)
You need the other 10 of those numbers to radicals, or numbers similar to pi (THESE ARE IRRATIONAL)
Step-by-step explanation:
Percent = part/whole
It wants you to find the % of change so it's 3.25 / 3.75
And that comes out to be 0.86 (with the 6 repeating)
So you move the decimal over 2 places to find the percent.
And then it's 1 - Ans
The answer is 13.33%
Using Gauss's method
Total number of terms = [15-(-129)]/4+1=36+1=37
Add
S=15+11+7+....-125-129
S=-129-125-...+7+11+15
--------------------------------
2S=-114-114-114...(37 times)
=>
sum=S=(1/2)*(-114)*37=-2109
Using AP, T(n)=15+11+7+....-129
T(n)=19-4n => T(1)=15, T(37)=-129
S(n)=(1/2)(37)(T(1)+T(37)=(1/2)37(15-129)=2109
195 ÷ 4 = 48.75
Is this what you wanted?
