Answer:
The millimeter.
Step-by-step explanation:
The best choice here is the millimeter (mm).
To find y you must recognize that 141+3y=180 . You know this since half of a circle is 180, and a line is basically half a circle if you arc from end point to end point.
You can then subtract 141 from both sides,
3y = 39
Then divide both sides by 3,
y=13
You would want to use 39° for 3y° since 3·13= 39.
A triangle can only contain 180°, so you would add 68 and 39 together and then subtract this from 180 to give you x.
68 + 39 + x = 180
107 + x = 180
x = 73

Answer: Option 'D' is correct.
Step-by-step explanation:
Since we have given that
Rate at which Alina swim = 2.5 miles per hour
Rate at which Talia swim = 1.8 meters per second
First we need to change meters per second into miles per hour
As we have given that

and

So, to change into miles per hours, we'll apply this,

So,
Difference between their rates will be given by

Hence, Talia swims about 1.5 miles per hour faster than Alina.
So, Option 'D' is correct.
