Bob took 20 math test last year if he failed 6 of them what percent of the math test did he pass

2 answers:

8 0

6 out of 20=what percent?
6/20=x%

percent means parts out of 100
x%=x/100

6/20=x/100
time both sides by 100
30=x
answer is 30% passed

100-30=70
70% is answer

70 %

6 is the 30% percent of 20, so 70% refers to the percent of the math test he passed

How to solve piecewise functions step by step?

Zanzabum

If you can graph a function, you can graph piecewise functions. Each one of them is a different line or curve within the domain for that specific line of curve. If the domain states it's less than or greater than a number, you circle that point on the line. If the domain states it's also possibly equal to the point at the beginning or the end, you make a closed dot.

I"m sure that's clear as mud, please respond with any additional questions.
