The first thing you should do is write each speed in vector form.
v1: vector water velocity
v2: vector boat speed with respect to water
writing the vectors we have
v1 = (5 * COS (20 * (PI () / 180)) i) + (5 * SENO (20 * (PI () / 180)) j)
v2 = (30 * COS (30 * (PI () / 180)) i) - (30 * SENO (30 * (PI () / 180)) j)
The vector representing the ship's current motion will be given by the sum of vectors v1 and v2
v1 + v2 = (30.67922522 i) + (15.67922522 j)

Three families shared the cost of purchasing a $5,000 generator. The martins paid 1/3 of the cost and the millers paid 40% and t

Umnica [9.8K]

Answer:

The amount Paid by Brown for generator =$ 2000

Step-by-step explanation:

Given as ,

The total cost of generator purchasing = $5,000

Millers paid 40% of the total cost of generator,

i.e 40% of $5,000

Or, 0.4 × 5,000

Or, $2,000

So, Millers paid amount = $2,000

So,. rest amount is now = $5,000 - $2,000 = $3,000

Again, Martins paid $\frac{1}{3}$ of $ 3,000

Or Martin paid amount = $1,000

Now, Again rest amount = $3,000 - $1,000 = $2,000

Now as per question, Brown paid the rest amount,

Hence Brown paid the rest amount for generator = $2,000 Answer
