Step-by-step explanation:
Fractions can be read as division. The top number (also called the numerator) is divided by the bottom number (also called the denominator).
4 / 10 = 0.4
So, the answer is 0.4.
12Sqrt(3)
This is because we can find the height and base of the triangle by using 30-60-90 triangles. Because the center point bisects the 60 degree angles in each corner, we can make 30-60-90 triangles. Then using porportions, you'll find the height of the triangle is 6 and the base is 4sqrt(3). Then use the area of a triangle formula.
Answer: If you take the square root of a number that is not a perfect square, it is going to be irrational. And then if you just take that irrational number and you multiply it, and you divide it by any other numbers, you're still going to get an irrational number. So square root of 8 is irrational. You divide that by 2, it is still irrational.
