7k + 2m = kr + 4m + 3
7k - kr = 4m - 2m + 3
7k - kr = 2m + 3
k(7 - r) = 2m + 3
k = (2m + 3) / (7 - r)

Suppose a river flows south to north at a velocity of 1 m/s, and a motorboat traverses the river from east to west at a speed of

irina1246 [14]

Answer: $24^{\circ}$

Step-by-step explanation:

Given

River is flowing from south to North with a velocity of $u=1\ m/s$

Motor boat traverses the river from east to west at a speed of $v=2.5\ m/s$

South component of boat velocity must compensate the river velocity in order to travel in west direction.

$\therefore v\sin \theta=u\\\\\Rightarrow 2.5\sin \theta=1\\\\\Rightarrow \sin \theta=\dfrac{2}{5}\\\\\Rightarrow \theta=23.57^{\circ}\approx 24^{\circ} \text{south of west}$

Between which two integers does the square root of 17 fall between?

Mrrafil [7]

Two integers mean numbers that do not have decimals. Whole numbers

to figure out between what two integers get a calculator and do square root 17
which is 4.123 (to three decimal places)

thus it falls between 4 and 5. since it is above 4 and below 5 and there are no integers in between possible.

Hope this helps :P
