It is the second and third boxs
The square root of a whole number will be rational if the whole number is a perfect square (i.e 1, 4, 9, 16, 25, 36, 49, 64, 81, 100, 121, 144 etc) and irrational otherwise.
Rational number is a number that can be described as m/n
so a fraction can be a rational number, 0.8=4/5
Irrational numbers can't be written as a fraction
The part about the number having to be a perfect square is still correct, if it's not a prefect square than it will just keep going(a decimal that never ends)
for example the square root of 0.64 is 0.8
and the square root of 10 is 3.162277...
as you can see the 0.64 one ends and is rational, whereas the 10 one just keeps going and is irrational.
Answer:
The answer is A,C, and D
Step-by-step explanation:
Answer:
x=60
Step-by-step explanation:
So basically the sum of interior angle of a triangle is 180.
Add all the values and make it equal to 180.
x+3/2x+1/2x=180
Then find x
3x=180
x=180/3
x=60 degrees
