Answer:
5/9
Step-by-step explanation:
Let's define:
The following three equations are established from the question:
sw + j + sk = 120
sw/j = 8/3
j/sk = 3/4 or sk/j = 4/3
Dividing the first equation by j, we get:
sw/j + j/j + sk/j = 120/j
8/3 + 1 + 4/3 = 120/j
5 = 120/j
j = 120/5 = 24
sw = 24*8/3 = 64
sk = 24*4/3 = 32
After the replacement the new number of jeans and skirts are:
j' = 24 - 4 = 20
sk' = 32 + 4 = 36
the new ratio of jeans to skirts is:
j'/sk' = 20/36 = 5/9
it's a right angled triangle so we will use hypotenuse formula to get the value of x
hypotenuse formula = a² + b² = c²
a = side of the triangle
b = base of traingle
c = hypotenuse ( can be written as h too)
and the formula can also be written as.
c² = a² + b²

Answer:
D
Step-by-step explanation:
![(a^{m})^{n}=a^{m*n}\\\\a^{m}*a^{n}=a^{m+n}\\\\a^{-m}=\frac{1}{a^{m}}\\\\\\(6n^{-5})(3n^{-3})^{2}=(6n^{-5})*3^{2}*n^{-3*2}\\\\=6n^{-5}*9*n^{-6}\\\\=6*9*n^{-5 +(-6)}\\\\=54n^{-11}\\\\=\frac{54}{n^{11}}](https://tex.z-dn.net/?f=%28a%5E%7Bm%7D%29%5E%7Bn%7D%3Da%5E%7Bm%2An%7D%5C%5C%5C%5Ca%5E%7Bm%7D%2Aa%5E%7Bn%7D%3Da%5E%7Bm%2Bn%7D%5C%5C%5C%5Ca%5E%7B-m%7D%3D%5Cfrac%7B1%7D%7Ba%5E%7Bm%7D%7D%5C%5C%5C%5C%5C%5C%286n%5E%7B-5%7D%29%283n%5E%7B-3%7D%29%5E%7B2%7D%3D%286n%5E%7B-5%7D%29%2A3%5E%7B2%7D%2An%5E%7B-3%2A2%7D%5C%5C%5C%5C%3D6n%5E%7B-5%7D%2A9%2An%5E%7B-6%7D%5C%5C%5C%5C%3D6%2A9%2An%5E%7B-5%20%2B%28-6%29%7D%5C%5C%5C%5C%3D54n%5E%7B-11%7D%5C%5C%5C%5C%3D%5Cfrac%7B54%7D%7Bn%5E%7B11%7D%7D)
