Answer: cage  I

Step-by-step explanation:

Given

43 gm of copper and 7 gram of other metal

Another cage has 83 gram of copper and 17 gm of other metals

Here, the percentage of copper is

For the first case

\Rightarrow \dfrac{43}{43+7}\times 100=86\%

For the second case

\Rightarrow \dfrac{83}{83+17}\times 100=83\%

So, the cage-I has more percentage of copper

Identify the factors of 9x2 + 30x + 25.
svlad2 [7]
