Athermometer measures temperature to the nearest 0.5°c which measurement shows an appropriate level of precision for the thermometer.
a.21.55°c
b20°c
c.16°c
d16.0°c

D

Step-by-step explanation:

To the nearest 0.5°C means basically 1 digit after the decimal point.

0.5 has 1 digit (5), after the decimal point. To the nearest 0.5 means that the answer should have 1 digit after the decimal point.

For example, if we were to round 14, to the nearest 0.5, we would need to write it as  14.0 (with 1 digit after decimal).

Now, looking at the answer choices, we eliminate A because it has 2 digits after decimal. We eliminate B and C because there is NO DIGIT after decimal. And we accept D, because it has 1 digit after decimal. Hence, this is correct to the nearest 0.5°C.

Answer is D

14 ft 7 inches

step-by-step explanation:

7×25" = 175"

at 12" per foot, that is 14 feet, 7 inches.
