Answer:
The number of girls in German club are
.
Step-by-step explanation:
Consider the provided information.
of n are boys.
Thus the number of girls are:
.
1/3 of the girls in the club study Spanish.
Girls studying Spanish = ![\frac{3n}{5}\times\frac{1}{3}=\frac{n}{5}](https://tex.z-dn.net/?f=%5Cfrac%7B3n%7D%7B5%7D%5Ctimes%5Cfrac%7B1%7D%7B3%7D%3D%5Cfrac%7Bn%7D%7B5%7D)
That means now total number of girl left: ![\frac{3n}{5}-\frac{n}{5}=\frac{2n}{5}](https://tex.z-dn.net/?f=%5Cfrac%7B3n%7D%7B5%7D-%5Cfrac%7Bn%7D%7B5%7D%3D%5Cfrac%7B2n%7D%7B5%7D)
5/6 of the remaining girls study French.
Girls studying French = ![\frac{2n}{5}\times\frac{5n}{6}=\frac{n}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B2n%7D%7B5%7D%5Ctimes%5Cfrac%7B5n%7D%7B6%7D%3D%5Cfrac%7Bn%7D%7B3%7D)
That means now total number of girl left: ![\frac{2n}{5}-\frac{n}{3}=\frac{n}{15}](https://tex.z-dn.net/?f=%5Cfrac%7B2n%7D%7B5%7D-%5Cfrac%7Bn%7D%7B3%7D%3D%5Cfrac%7Bn%7D%7B15%7D)
The rest of the girls in the club study German.
Hence, the number of girls in German club are
.
we are given
In A 4 year period, About 80,000 acres of coastal wetlands in United States are lost each year.
so, total area =80000 acres
total time = 4 years
now, we can use formula
total change in wetlands = ( total area)/(total time)
now, we can plug values
total change in wetlands is
![=\frac{80000}{4} acre/year](https://tex.z-dn.net/?f=%3D%5Cfrac%7B80000%7D%7B4%7D%20acre%2Fyear)
