At the start of his diet, Kerrin weighed 14 stone 8
pounds. Three months later he weighed 13 stone
6 pounds. There are 14 pounds in a stone.
Calculate the reduction in Kerrin's
weight as a percentage of his
initial weight, correct to 1 d.p.

At the start  of the diet Kerrin weighted 14*14+8 = 196+8=204 pounds

Three  month  later                                   13*14+6=182+6=188 pounds

188=p% from 204

188=204p/100

188*100=204p

p=18800/204=92.156≅ 92.2

Step-by-step explanation:

65° North of West

Step-by-step explanation:

-The resultant force acts in an angle that proportionally bisects the two positions.

-We apply  the tan inverse to find the direction of the resulting force:

The angle of the resulting force is 65°, and the direction of the force is North of West.
