Answer:
Step-by-step explanation:
y = A(1 - r)^t......y = value of car after t years.....A = original cost....r = rate of depreciation.....t = time in years
y = 12,282.50
A = 20,000
r = 15% = 0.15
12,282.50 = 20,000(1 - 0.15)^t
12,282.50 / 20,000 = 0.85^t
0.614125 = 0.85^t
log 0.614125 = t * (log(0.85))
t = (log 0.614125) / (log 0.85)
t = 3 <=== 3 years old

Step-by-step explanation:
Since the cardboard box is a cube all it's sides are equal
Volume(V) of a cube = l³
where l is the length of one side
From the question
The length of each side of the cardboard box is
We have the final answer as

Answer:
208 cm2 (C)
Step-by-step explanation:
16*6=96
The area of the LEFT polygon is 96 according to length times width.
Since the entire length is 14 and the rectangle alone has a length of 6, 14-6=8 which then you multiply by 14 to get your area of the RIGHT polygon.
8*14= 112
When you add both area values together you get the area of the entire polygon.
96+112=208
To divide like bases just subtract the exponents
answer is 2^(13-3) or 2^10 or 1024
