Marisa painted 1/2 of her bedroom in 3/4 of an hour. at this rate how long will it take her to paint the entire room. as fast as possible.

she did 1/2 , so she has 1/2  more to do

 it took her 3/4 so multiply that by 2

3/4 x 2 = 1 1/2 hours total

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.
