AI Thread Summary
To solve the equations x + y = 60 and x² = 0.25, first express y in terms of x using y = 60 - x. Substitute this expression into the second equation to form a quadratic equation. Solving this quadratic will yield the values for x and subsequently for y. The discussion emphasizes that there is a theoretical solution since there are two equations with two unknowns. This method is a standard approach for solving such algebraic problems.

x+y=60

x2 = 0.25
y2

find x and y

it's part of a massive physics question, and i'll post the whole thing and my workings so far if it turns out that this maths question is impossible.

You have two equations in two unknowns, so in theory there is a solution.

I suggest using the first equation to express y in x (i.e. rewrite x+y=60 to y=60-x), then plug that into the second one and solve the resulting quadratic equation for x.
 
TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...
Thread 'Variable mass system : water sprayed into a moving container'
Starting with the mass considerations #m(t)# is mass of water #M_{c}# mass of container and #M(t)# mass of total system $$M(t) = M_{C} + m(t)$$ $$\Rightarrow \frac{dM(t)}{dt} = \frac{dm(t)}{dt}$$ $$P_i = Mv + u \, dm$$ $$P_f = (M + dm)(v + dv)$$ $$\Delta P = M \, dv + (v - u) \, dm$$ $$F = \frac{dP}{dt} = M \frac{dv}{dt} + (v - u) \frac{dm}{dt}$$ $$F = u \frac{dm}{dt} = \rho A u^2$$ from conservation of momentum , the cannon recoils with the same force which it applies. $$\quad \frac{dm}{dt}...
