The equation a = 640s gives the relationship between s square miles and a acres. bob owns 3.5 square miles of farmland. how many acres does he own?

the probability that a bird is green (.30) is true

step-by-step explanation:

  or  

sin y = 7/q

7 is the opposite side length, q is the hypotenuse

tan y = 7/r

7 is the opposite side length, r is the adjacent side length

using sohcahtoa ^^^^

cos y = adjacent/hypotenuse

cos y = r/q
