An empty 6-gal water jug weighs 0.5 lb. with 3 c of water inside, the jug weighs 2 lb. which equation models the jug’s weight y when it contains x cups of water? a) y= 0.5x-0.5 b) y= 0.5x+0.5 c) y= -0.5x-0.5 d) y= -0.5x+0.5

J = jug

J = 0.5x + 0.5

the slope would be 2/3 because that would leave pounds when multiplied by cups.

add 0.5 for the weight of the water jug

y = (2/3)x + 0.5

256π units²   (answer b)

step-by-step explanation:

the formula for the surface area of a sphere of radius r

is             a = 4πr²

and so, if r = 8 units, then the surface area is:

a = 4π(8 units)² = 256π units²   (answer b)
