Answer 1

Answer:

a. The possible actual measurements are 2.251 cm, 2.349 cm and 2.295 cm.

b. Rounded measurement in meters is 0.023 meters

a. To determine which measurements could be the actual measurement of the rainfall, we need to consider how rounding works.

When rounding to the nearest tenth of a centimeter, any measurement with a hundredth digit of 5 or greater rounds up, and any measurement with a hundredth digit less than 5 rounds down.

Given that the rounded measurement is 2.3 cm, let's evaluate the measurements:

2.251 cm: Rounds down to 2.3 cm

2.349 cm: Rounds up to 2.3 cm

2.352 cm: Rounds up to 2.4 cm

2.295 cm: Rounds down to 2.3 cm

So, the possible actual measurements are 2.251 cm, 2.349 cm and 2.295 cm.

b. To convert the rounded measurement to meters, we need to divide it by 100, since there are 100 centimeters in a meter.

Rounded measurement: 2.3 cm

Conversion to meters: 2.3 cm / 100 = 0.023 meters

Equation: Rounded Measurement (in meters) = Rounded Measurement (in centimeters) / 100

Rounded Measurement (in meters) = 2.3 cm / 100

= 0.023 meters
