1925Chris walks a total of 260 miles during the 10 weeks (5+5+8+8)*10
He needs to lose 7.5 pounds which equals 26 250 calories (1 pound fat = 3500 calories)
To find out how fast he needs to go you have to divide the amount of calories he needs to burn with the amount of miles he walks. 26250 / 260 = 101
So Chris needs to burn at least 101 calories per mile and the slowest speed that allows him to do that is 4 mph (102 calories per hour) which is
C34Don't really know how to explain this... But
C explains a flaw in the argument by pointing out that the anarchists at a demonstration does not have to agree with the official aim of the demonstration (which the author says they do)
42You know that the 5-year average 1911 is 13.66. This means that 1911 and the four previous years have an average of 13.66. You can use this to find the value of X.
13.66*5=68.3
14.9+13.3+X+13.7+13.4 = 55.3+X
68.3 = 55.3 + X
X = 13.0
You can now find the 5-year average for 1909.
13+13.7+13.4+14.4+13.4 = 67,9
67,9 / 5 = 13.58
C48Amy has 4 grandparents. This means that she has 8 great grandparents. This means that she should have 16 great-great grandparents. However, two sisters from one family married 2 brothers from another family. This means that two great grandparents (the two brothers) only have 2 parents instead of 4 (great-great grandparents to Amy) and two other great grandparents (the two sisters) also only have 2 parents instead of 4 (great-great grandparents to Amy). This means that there are 4 great-great grandparents less than usual which means that Amy has 12 great-great grandparents
COkay, that last explanation was extremely poor, but try to draw the family tree as a picture and you should see how it's connected
