Melanie and Michael are on the north bank of a river that is flowing east to west at a speed of 0.5 m/s. They paddle their surf
IRINA_888 [86]

Answer:

total distance travel by them to cross river is 17.3 m

Step-by-step explanation:

Assume A be the initial position of both person and B as apposite point to A

u  component of velocity along SOUTH DIRECTION is 4 cos30 = 0.4330 m/s

v  component of velocity along SOUTH DIRECTION is 4 cos90 = 0 m/s

total speed will be = 0.4330 + 0  = 0.4330 m/s

time taken= \frac{width/ of/ river}{speed}

time taken = \frac{30}{0.4330} = 69.3 sec

component of u in downstream direction = 4 cos120 = -0.25 m/s

component of v in downstream direction = 4 cos 0 = 0.5 m/s

total component in downstream will be -0.25 + 0.5 = 0.25

total distance travel by them to cross river is = 0.25\times 69.3 = 17.3 mdownstream.

2(x+7)+3(x+1) what is the answer
barxatty [35]

Answer:

5x + 17

Step-by-step explanation:

To answer this question, we must first simplify:

2 (x + 7) + 3 (x + 1) = 2x + 14 + 3x + 3

Then, we have to combine like terms:

2x + 14 + 3x + 3 = 5x + 17

And there is our answer, 5x + 17

Hope this helps ! :)

Help this type of work confuses me
Dmitrij [34]

Answer/Step-by-step explanation:

Given:

-x + 3x + 1 + 4(x + 2) = 54

To solve, first open the bracket by applying the distributive property. Multiply every term you have in the bracket by 4

-x + 3x + 1 + 4x + 8 = 54

Add like terms together

6x + 9 = 54

Subtract 9 from each side

6x = 54 - 9

6x = 45

Divide both sides by 6

x = 45/6

x = 7.5
