Answer:
Actual value after 5 years is £1344 more than John's value.
Step-by-step explanation:
Johns estimate:-
V = k/t (inverse proportionality) where V = value of the car and t = it's age.
When t = 2, V = £12,000:-
12,000 = k/2 giving k = 24,000
Therefore the value at 5 years of age, according to John's proposition is
V = 24,000 / 5 = £4,800
The actual value using the given depreciation is
12000(1 - 0.2)^3 = £6144
Difference is £1344
Answer:
288 cm³
Step-by-step explanation:
The volume (V) of the triangular prism is
V = area of triangular base × height
area of base = 
× 6 × 8 = 24 cm², hence
V = 24 × 12 = 288 cm³
31/2 ÷ 7
= 31/2 ÷ 7/1
= 31/2 × 1/7
= 31/14
= 2/3/14
