3/10 due to there being 10 marbles (for white) for blue 7/10
Check the Wronskian determinant:

The determinant is not zero, so the solutions are indeed linearly independent.
If you call
the mass of the ant and
the load, we have the equation

In fact, the mass of the ant is one tenth of the load, which is exactly what this equation states.
Since we are given the load, we simply need to plug its value in the equation to deduce the mass of the ant:

Answer:

Step-by-step explanation:
velocity of river with respect to ground = 4 mi/h south

Velocity of swimmer with respect to river = 2 mi/h east

According to the formula of relative velocity


Where, V(S,G) be the velocity of swimmer with respect to ground, it is true velocity of swimmer.

Hey man I’ve never seen nothing like this but I’d you’re doing math on ap classroom , man , GOOD LUCK
