Answer:
6%
Step-by-step explanation:
3/20=4/x
It is a indirect proportion so we reciprocal,
Then,
3/20=x/40
3×40=20×x
120=20x
x=120/20
x=6
7) y= x^2-4x
8) y= 2x^2-3x+1
9) y= 9x^2-4
1 1/4mi = 6600 and
3 3/8 t = 6750 lb.
it would be 2(2^5), which is two times two to the fifth power. you take the original size and double it for every minute, which is like squaring it, but to the power of five, because it doubles once every minute for five minutes. i hope this makes sense!:)
