Question
Transcribed Image Text:7. For each of the following, place a decimal point in the number to make the
sentence reasonable:
a. A stack of 10 dimes is 1000 mm high.
b. The desk is 770 m high.
c. The distance from one side of a street to the other is 100 m.
d. A dollar bill is 155cm long.
e. The basketball player is 1950 cm tall.
f. A new piece of chalk is about 8100 cm long.
g. The speed limit in town is 400 km/hr.
Expert Solution
Step 1: The reasonable values.
To make each sentence reasonable, we need to add decimal points in the numbers.
(a) A stack of 10 dimes is 100.0 mm high. (This means each dime is 10.0 mm high, and the stack is 100.0 mm high in total.)
(b) The desk is 77.0 cm high. (A desk that is 770 meters high would be extremely tall, whereas 77.0 cm is a more reasonable height for a desk.)
(c) The distance from one side of a street to the other is 100.0 meters. (This would represent a typical street width. Without the decimal point, it would imply an exceptionally wide street, which is less common.)
