Answer:
1/35
Step-by-step explanation:
-3/7 / -15/1 =
3/7 * 1/15 =
3 / 105 =
1/35
By the Pythagorean theorem,
.. x^2 +(x -46)^2 = (x +4)^2
.. 2x^2 -92x +2116 = x^2 +8x +16
.. x^2 -100x +2100 = 0
.. (x -50)^2 -400 = 0
.. x = 50 ±20 . . . . . only x=70 makes any sense in the problem
The height, x, of the tree is 70 meters.
₤ 152352
depreciation factor = 100 - 8 = 92% = 0.92
current value = ₤ 180000 × (0.92)² = ₤ 152352
