Which of the following is a reasonable estimate for the weight of an 18-wheeler truck?
a.
8 × 10-4 lb
b.
8 × 102 lb
c.
8 × 10-2 lb
d.
8 × 104 lb

The reasonable estimate for the weight of an 18-wheeler is

Step-by-step explanation:

The average and legally maximum weight of an 18-wheeler is 80,000 pounds.

From option a through d, we check which of the measurement is close or equivalent to 80,000 pounds

By converting this, we have

By converting this, we have

By converting this, we have

By converting this, we have

From the 4 conversions, only   is equivalent to the average and legally maximum weight of an 18-wheeler, 80,000 pounds.

Hence, the reasonable estimate for the weight of an 18-wheeler is

area = length x width

length = 2 x width

32 = 2 x width x width

32 = 2 x width^2

36 = width ^2  

width = 6

length = 12

area is 32

perimeter = 2 x 12 + 2 x 6 = 24 + 12 = 36
