Two hoses are being used to fill a swimming pool. Water is pumped through through the first hoses at a rate 22 L/min and through the second hose at rate 18L/min. Write an algebraic expression for each situation. a) the amount of water pumped through the first hose after t min.
b)the amount of water pumped through the second hose after t min.
c)the total amount of water pumped into the pool from both hose after t min.
d)how much water has been pumped into the pool after 2.5 h?

Brittany has designed four different birdcages, each with the same volume: a square pyramid, a cylinder, a cone, and a sphere. the zoo wants to use one of brittany’s designs but plans to change the volume of the cage. find the design change that would result in the birdcage with the greatest volume. a.) increase the area of the base of the square pyramid by a factor of ten. b.) increase the height of the cylinder by a factor of ten. c.) increase the radius of the cone by a factor of ten. d.) increase the radius of a sphere by a factor of ten.
