Answer:
The answer is B
Step-by-step explanation:
37. Volume: l×w×h
38. Volume: (pi)r^2×h
39. Volume: (1/2b×h)×l
37. l=4
w=4
h=6
4×4×6
16×6= 96ft^3
38. (pi)=3.14
r=5
h=12
(3.14×5^2)×12
(3.14×25)×12
78.5×12= 942in^3
38. b=4
h=3
l=8
(1/2×3×4)×8
(1/2×12)×8
6×8= 48
4848 inches is how long the bike will be
Answer:
12 years
Step-by-step explanation:
T + 5 = A
Therefore T =A - 5
In three years T = 3+ (A-5)
thus T = A - 2
Also in three years T = 2/3 (A+3)
Equating the two
A -2 = 2/3 (A+3)
3A - 6 = 2A + 6
3A - 2A = 6 + 6
Therefore A = 12
