Hello,
It 's difficult to translate that in french.

w=2^(1/5)
Area=32^(1/5)=(2^5)^(1/5)=2 (in²)
Advocates replacing foreign imports with domestic production.<span> It is based on the premise that a country should attempt to reduce its foreign dependency through the local production of industrialized products.

We can use ratios and the cross-multiply-divide to find this.
The ratio 21:5 is avaliable via the question. We then need to compare that to the ratio x:100, the 100 being the percent and the x being the number of airplane parts.
21/5 = x/100
We can then solve for x to find the number of airplane parts. First we multiply by 100 on both sides to get 2100/5 = x. Therefore x = 420 and there are 420 airplane parts.
The Answer is D!!
Hope this helps
