Irrational numbers are numbers with infinite decimals values that are not repeating (ex. Pi 3.14159265....). Whole numbers don’t have decimal values in the first place, so all whole numbers are therefore rational.
Keep in mind that just because a number has decimal values doesn’t mean it’s irrational (ex. 4.5 is a rational number). It needs to have infinite non-repeating decimal values to be irrational.
Answer:15.57

a.
x • 0.2 = 75
so 75 ÷ 0.2 = x
answer is 375
use the above model to help you solve the "x is y% of z" problems
Answer:
Let's define A as the area given by the integral:
Which is the area between the curve y = 3*x^4 and the x-axis between x = -1 and x = 1
To find the volume of a revolution around the x-axis, we need to multiply the area by 2*pi (a complete revolution)
where pi = 3.14
First, let's solve the integral:
Then the volume of the solid is just:
V = (6/5)*2*3.14 = 7.536
