"My wife is really mad at the fact that I have no sense of direction. So I packed up my stuff and right!"
Answer:
Step-by-step explanation:
Given,
Cost price of three thermos flask = 1080
Selling price of each thermos flask = 400
<u>Finding </u><u>the </u><u>selling </u><u>price </u><u>of </u><u>three </u><u>thermos </u><u>flask</u>
Since, the cost of 3 thermos flask is more than that of 1 thermos flask. So, the cost of 1 thermos flask is multiplied by 3 ( i.e 400 × 3 = 1200 )
Here, the selling price is greater than cost price.
So, there is profit.
And we know that,
⇒
⇒
Profit amount = 120
<u>Finding </u><u>the </u><u>profit </u><u>percentage</u>

The flying drones are illustrations of the laws of cosines
Both flying drones would be 128.13 meters apart after 1 hour
<h3>How to determine the distance between them</h3>
For drone A, we have:
- Angle =120 degrees
- Speed = 80 mph
So, the distance after one hour is:
Distance = 80 m
The distance is calculated using:
Distance = Speed * Time
For drone B, we have:
- Angle = 320 degrees
- Speed = 50 mph
So, the distance after one hour is:
Distance = 50 m
The angle between them is calculated as:
This gives
Using the laws of cosine, the distance (d) between them after 1 hour is:
So, we have:
Evaluate the expression
Hence, both drones would be 128.13 meters apart after 1 hour
