Answer: 12 cm
Step-by-step explanation:
The masses of the spheres are proportional to their volums, and the cube of the ratio is k^3=135/5=27 ==> k=3
The greater radius is 3*4=12 (cm)
x=25,y=15 Not to sure abt this answer but I think I got it
Answer:
40%
6/15=favorable amount/total amount
6/15=2/5
2/5*20
The equation cannot be solved, but it can be simplified.
You can't add variables with different exponents. For example, you can't add
with because they have different exponents
