Answer:
18 yd
Step-by-step explanation:
The sum of the three lengths rounded to the nearest yard is ...
... 2 yd + 15 yd + 1 yd = 18 yd

<em>Comment on this result</em>
In this case, this also happens to be the rounded value of the actual sum (17.94 yd ⇒ 18 yd). Sometimes, rounding the addends results in an error in the total, because rounding can introduce a bias if the numbers are not uniformly distributed.

Answer: 7/10
Explanation:
Find the common denominator:
Since 2/5 and 3/10 has a common of denominator of ten, solve.
2/5 + 3/10 = 2/5 * 2/2 = 4/10 + 3/10 = 7/10
Therefore, the sum of 2/5 + 3/10 = 7/10
There are 12 five minutes in one hour and 1 hour correspond to 360°, then each 5 minutes represents 360/12 = 30°
From 1:20 to 1: 55 we have 35 minutes or 7 x 5 minutes or
7 x 30° = 210°
To convert degree into radian, we apply the following formula:
degree/180° = radian/π
210/180 = r/π or (cross multiplication) →Radian = (π x 210/180
→ Radian = 7π/6 (simplify by 30)
