Michelle is on a secret mission to reclaim artifacts that were recently stolen from the National Museum. The artifacts are located in a private manor just outside the city. The rectangular base of the manor is 60\text{ m}60 m60, start text, space, m, end text by 30\text{ m}30 m30, start text, space, m, end text. Help Michelle plan her mission by redrawing the base of the manor by moving points on the grid below.

3: 2

step-by-step explanation:

shorter piece is 2: 3, so just reverse it, and you get 3: 2

the answer is (4,3)

since the rule for r0, 90º is (-y,x) and it was already applied to form the image, all you have to do is reverse the answer using this formula.

ending amount = beginning amount / (2^n)

where "n" = number of half-lives (or elapsed time / half-life)

ending amount = 50 mg / (2 ^10 / 5.3)

ending amount = 50 mg / (2 ^ 1.8867924528)

ending amount = 50 m / 3.6981210597

ending amount = 13.5203794557 mg

or about 13.5 mg remain
