Answer: I cant tell which one is a or b or c or d but ill say its b
767 rounded to the nearest ten is 770
1 4/5 - 2/5 = r you minus the total she has already walked or ran from the total she plans on running to get “r”
You want log √(9/25). Recognizing that √9 = 3 and that √25 = 5, we get
log 3/5, which by rules of logs comes out to log 3 - log 5.
To four decimal places:
log 3 - log 5 = 0.4771 - 0.6990, or -0.2218.
Lets take 100 and divide it by 4 to get 25, this means that 1 first part of 100 is 25 these means that the porcentage of 1 in 4 is 25%
Hope this helps
