The surface area of two similar solids are 245cm^2 and 125cm^2. If the volume of the smaller
solid is 500cm^3, what is the volume of the larger
solid?

Four airplanes carrying a total of 400 passengersarrive at the detroit airport. the airplanes carry, respectively,50, 80, 110, and 160 passengers.a) one of the 400 passengers is selected uniformly at random.let x denote the number of passengers that were on theairplane carrying the randomly selected passenger. find var(x)for x as given in the problemb) one of the 4 airplane drivers is also selected uniformly atrandom. let y denote the number of passengers on the chosen driver’s airplane. find var(y) for y as given in the problem

X+ y = 5 ; x - y =3 solve using linear combination

0if x and y vary inversely and y=6 as x=7, what is the constant of variation?
