You find that, as a joke, he filled his swimming pool with kool-aid, which dissolved perfectly into the water. however, now that you want to swim, you must remove all of the kool-aid contaminated water. the swimming pool is round, with a 13 foot radius. it is 11.5 feet tall and has 9.5 feet of water in it. how much work is required to remove all of the water by pumping it over the side? use the physical definition of work, and the fact that the weight of the kool-aid contaminated water is σ=63.4lbs/ft3

step-by-step explanation:

let pq = qr = rs = x, and xz = y and zu = z.

if the horizontal lines are parallel, then corresponding segments are in proportion:

substitute:

therefore 3 = y = z.

xu = y + z → xu = 3 + 3 = 6

i would think "anyone would want the best for their child" is correct

answer:

the answer is b) divide by -4 on each side and flip the sign.

step-by-step explanation:

we first need to start by dividing. this is because it is a multiplication problem to start.

we also need to make sure we flip the sign because any time you multiply or divide by negative numbers, the sign must be flipped.
