7. Mindy has a watch that was from her great-grandfather. She has it appraised and finds it is worth $3500. She wants to sell it, but the appraiser tells her that the value is appreciating (growing in value) by 7% per
year. In how many years will the value of the watch be $7000?

step-by-step explanation:

x^2 -12x + 36 + y^2 = 36

x^2 + y^2 = 12x

r^2 = 12rcos(theta)

r = 12 cos(theta)

4/6 = 2/3

so it should take 3/3 hours per man. so 9 hours is the answer 3*3 =9

step-by-step explanation:

1/800 is the right answer
