Which decimals are rational numbers? select all that apply
a. 72/100
b. π
c. 1 1/3
d. 8/526
e. 0.
f. 5/9

Step-by-step explanation:

Fractions are always rational.

A --> this is rational because it can be represented by a fraction.

B --> this is irrational because it cannot be represented by a fraction

C --> 1 1/3 is rational because it can be represented as a fraction

D --> 8/526 is rational because it can be represented as a fraction

E --> this is irrational because it cannot be represented by a fraction

F --> this is rational because it can be represented as a fraction

I hope this helps!

step-by-step explanation:

there is a formula i can give you:

it is r^2*n*sin(360/n) divided by 2 where r represents the "radius" and n is the number of sides.

plug them in:

(10sqrt(3))^2*6*sin(360/6) divided by 2

100*3*6*sin(60) divided by 2

900*sin(60)

900*sqrt(3)/2

450*sqrt(3)

approx is 779.4 cm^2

your question is incomplete, write all the numbers in the sequence that it tells you.
