Answer:
Savings = $13
Step-by-step explanation:
$0.12 = 1 kilowatt-hour
So,
For Top-Freezer Refridgerator:
$0.12 × 529 = 1 × 529 kilowatt-hour
$63.48 = 529 kilowatt-hour
For Side-by-Side Refridgerator:
$0.12 × 634 = 1 × 634 kilowatt-hour
$76.08 = 634 kilowatt-hour
Savings = Side-by-Side Refridgerator - Top-
Freezer Refridgerator
Savings = $( 76.08 -63.48 )
Savings = $12.6
Savings = $13
It means to most likely isolate the variable and you should have something like w= or a number =w
Answer:
The distance between the ship at N 25°E and the lighthouse would be 7.26 miles.
Step-by-step explanation:
The question is incomplete. The complete question should be
The bearing of a lighthouse from a ship is N 37° E. The ship sails 2.5 miles further towards the south. The new bearing is N 25°E. What is the distance between the lighthouse and the ship at the new location?
Given the initial bearing of a lighthouse from the ship is N 37° E. So,
is 37°. We can see from the diagram that
would be
143°.
Also, the new bearing is N 25°E. So,
would be 25°.
Now we can find
. As the sum of the internal angle of a triangle is 180°.

Also, it was given that ship sails 2.5 miles from N 37° E to N 25°E. We can see from the diagram that this distance would be our BC.
And let us assume the distance between the lighthouse and the ship at N 25°E is 
We can apply the sine rule now.

So, the distance between the ship at N 25°E and the lighthouse is 7.26 miles.
