Rainfall collected in a rain gauge was found to be 2.3 cm when rounded to the nearest tenth of a centimeter.
a. circle all the measurements below that could be the actual measurement of the rainfall.
2.251 cm
2.349 cm
2.352 cm
2.295 cm
b. convert the rounded measurement to meters. write an equation to show your work.

(a). 2.251 cm , 2.349 cm, 2.295 cm

(b). 0.023 meters.

Step-by-step explanation:

(a). We are asked to to choose the options that shows the actual measurement of the rainfall.

Since the rounded figure is 2.3 cm, this means that either the tenths digit is 3 with hundredths digit less than 5, or tenths digit is 2 with hundredths digit greater than or equal to 5.

Let us check our given choices one by one.

Therefore, the correct choices are 2.251 cm , 2.349 cm  and 2.295 cm.

(b) We know that 1 cm equals 0.01 meters.

To convert 2.3 cm to meters, we will multiply 2.3 by 0.01.

Therefore, the rounded measurement of rain would be 0.023 meters.

A.2.251 cm , 2.349 cm, 2.295 cm

B. 0.023 meters.

C

Step-by-step explanation:

Since he writes 120 words in 3 minutes, we know that Tom will write 120 / 3 = 40 words in 1 minute, therefore the ratio is 40 : 1. It's not 1 : 40 because the question is asking for the ratio of words typed to minutes, not minutes to words typed.
