Answer:
33 feet.
Step-by-step explanation:
If the ratio of the student to their shadow and flagpole to its shadow are equal, then you can use the proportion
5.5/3 = x/18 and cross multiply to find x.
5.5 × 18 = 99
3 × x = 3x
3x/3 = x, 99/3 = 33.
x = 33.
Its a square( same sides)
its a right-angled triangle as half
18²=a²+a²
a=12.73
Answer:
Step-by-step explanation:
Cost of Truck = $60,000
Expected use = 100,000 miles
Residual value = $10,000
Depreciation per mile = ( Cost of Truck- Residual value)/ Estimated use
= ( 60,000-10,000)/100,000
= 50,000/100,000
= $0.5
Miles driven in first year = 16,000
Depreciation expense for first year = Miles driven in first year x Depreciation per mile
= 16,000 x 0.5
= $8,000
