11/40 is a fraction, and it is already in the simplest form. This is because they don't have any common factors, which means we can't use the GCF, greatest common factor, to divide each number. So 11/40 is already in simplest form.
So, 11/40ths is already in simplest form.
Hope I helped ya!! xD<span />
A quarter circle, is as what it name suggests, 1/4 of a circle. To get its area, you must get first the area of the circle as a whole -
A = pi * r^2
= 3.14 * 7cm^2
= 3.14 * 49cm^2
= 153.86cm^2 area of the whole circle
Then, divide the area of the whole circle by 4.
153.86cm^2 / 4 = 38.465cm^2
Therefore, the area of a quarter circle is 38.47cm^2
It would be 17because 17-8 is 9
The Expression is
(x^-2y^-4x³)^-2
We can combine the x terms inside the brackets using the concept;
x ^a × x^b = x^(a+b)
Therefore,
(x^-2)(x^3) = x^(3-2) = x^!
Thus we get;
(xy^-4)^-2
Using the concept
(x^a)^b = x^(ab)
Therefore
= x ^(-2×1) y^(-2×-4)
=x^-2y^8
But using the concept; x^-a = 1/x^a
Thus, x^-2y^8 = y^8/x²
Hence the simplified equation is;
= y^8/x²
