What is the midpoint of side ab in the triangle below?

a. ( -2 1/2, -1/2)
b. (1/2, 2 1/2)
c. (2 1/2, 1/2)
d. (-1/2, -2 1/2)

B

Step-by-step explanation:

half of 11 is 5.5 so counting that from either of the points leads to .5

Then continuing from there, half of 9 is 4.5 so moving the point up would get 2.5

fahrenheit

step-by-step explanation:

fahrenheit is more precise than celsius. the ambient temperature on most of the inhabited world ranges from -20 degrees fahrenheit to 110 degrees fahrenheit—a 130-degree range. on the celsius scale, that range is from -28.8 degrees to 43.3 degrees—a 72.1-degree range. this means that you can get a more exact measurement of the air temperature using fahrenheit because it uses almost twice the scale.
