The length of a pencil is measured with two rulers. Report the length of the pencil from each ruler with the proper number of di
gits.
1 answer:
Answer
Length measured with Ruler A= 1.17 dm
Length measured with Ruler B= 1.18 dm
Step-by-step explanation:
I included a missing image that shows the pencil's length as measured using two rulers.
Ruler A has a scale marked at 1 dm intervals.
Ruler B has a scale marked at 0.1 dm intervals.
Length measured with Ruler A= 1.17 dm
(The middle markings reveal that the pencil tip lies between 1 and 1.25, slightly above 1.125 but below 1.25, positioning it around 1.2 and 1.125 dm, approximately half of 1.25, which is 1.125, plus an increment of one of the three halves of that half, which gives 1.125+0.045 dm thus concluding to 1.17 dm.)
Length measured with Ruler B= 1.18 dm
(The pencil tip appears just shy of 1.2 dm, confirming the precise value is clearly 1.18 and not 1.19 dm.)
Tip: When unsure about the exact measure, it’s advisable to estimate one extra decimal beyond what the ruler presents.

Answer:
Step-by-step explanation:
Let x represent the speed of the first ferry.
Consequently, the second ferry's speed is x-5, as it travels 5 miles per hour slower.
The time taken by the first ferry is calculated as distance divided by speed =
The time taken by the second ferry equals .
Since the second ferry departs one hour earlier, the times differ by 1 hour.
The speed cannot be negative.
Thus, the speed of the first ferry is determined to be 18.5 mph,
and for the second, slower ferry, it equals 13.5 mph.
