I am gonna assume it is C)9/4 - 1/2i
For every 5 cashews, there are 6 peanuts and 7 almonds.
Means: Cashews:Peanuts:Almonds = 5:6:7
Sum of ratio = 5 + 6 +7 = 18
Cashews = (5/18) * 270 = 75
Peanuts = (6/18) * 270 = 90
Almonds = (7/18) * 270 = 105
So how many more what are there than peanuts?
The number of that nuts Minus the number of peanuts.
= Number of that nuts - 90
Since 689 / 35 is about 20, it would take around 4 seasons to break even
A) the middle of the range is 39.5%
b) the difference between the middle and the ends of the range is ±1.5%
c) less than a majority favor change. Change seems unlikely.
Make a proportion
x = the amount of miles walked in 137.5 min
25 137.5
--- = --------
2 x
cross multiply
25x = 275
divide both sides by 25
x = 11
paul walked 11 miles in 137.5 minutes
