A dog walks 12 meters to the east and then 16 meters back to the west

I’d have to say you don’t mean “how much is 12 + 16?”. I assume you are asking for a vector solution.

So, if East is “+” and West is “-”, then the resultant vector is “-4” (4 meters West).

So, how’s your homework going, anyway? :D

The dog walked backwards 4 meters.

emily ruth's annual premium is $1058.50

step-by-step explanation:

emily ruth is a female of 27 years age purchasing 20 year endowment insurance with face value $25000.

from the given table,

for females, the age of a male 3 years younger should be used.

so, we have to check for 24 year male for 20 year endowment.

it is 42.34 for every $1000 face value.

for a face value of $25000,

it is 25 * 42.34 = $1058.50

∴ emily ruth's annual premium is $1058.50
