4.5/3 = x/5
then:
x = 5 * 4.5 / 3 = 15/2 = 7.5
hope that helps
Answer:
coldsteppa and the call with your friends with the boys are you and you is not great for you to get out and he said he is not interested but I gotta do that for a lil I 5th year with you but you cant you are a treeeeee and I love your videos and I don't even think you talkin about the struggle of the bike and you have you ever been in the car and I don't think I might be my girlfriend eventually and you know you are a good day for you but you have a lot more to say you are not the only thing I have a relationship and you have a good time with me if I dont you can keep me in my life if I have a good time and I am
Answer:
Bottom left/ 3rd one
Step-by-step explanation:
The correct answer would be the 3rd one. Since they don't have numbers, it would be the bottom left one. A coin can land on heads or tails so the answer as to be splits to heads or tails which then splits into heads or tails.
There are a couple of ways to think about this.
1) Weight the speed by the time and compute the weighted average.
(60*2.5 + 75*1.5)/(2.5 + 1.5) = 65.625
Her average rate of speed is 65.625 mph.
2) Consider distance and time.
distance = speed * time
distance₁ = speed₁ * time₁
distance₂ = speed₂ * time₂
total distance = distance₁ + distance₂
total time = time₁ + time₂
And the average speed is given by
average speed = (total distance)/(total time)
Using the above formulas, we have
distance₁ = 60 mi/h * 2.5 h = 150 mi
distance₂ = 75 mi/h * 1.5 h = 112.5 mi
total distance = 150 mi + 112.5 mi = 262.5 mi
total time = 2.5 h + 1.5 h = 4.0 h
average speed = (262.5 mi) / (4.0 h) = 65.625 mi/h
Bette's average rate of speed is 65.625 mph.
R=5.4
4.2r-12.68=10
+12.68 +12.68
4.2r=22.68
4.2/4.2 22.68/4.2
22.68/4.2= 5.4
Hope this helps! Have a great day :)
