A fish was swimming LaTeX: 2\frac{1}{2}2 1 2 feet below the water's surface at 1:00 p.M. Three hours later, the fish was at a depth that is LaTeX: 3\frac{1}{4}3 1 4feet below where it was at 1: 00 p.M. What rational number represents the position of the fish with respect to the water's surface at 4:00 p.M.?

feet

Step-by-step explanation:

The depth of the fish to the surface of water at 1:00 pm = 2 feet

                                                                             =   feet

The depth of the fish to its initial position at 4:00 pm = 3 feet

                                                                              = feet

The position of the fish with respect to the water's surface at 4:00 pm = the depth of the fish to the surface of water at 1:00 pm + the depth of the fish to its initial position at 4:00 pm

                                        =   +

                                        =

                                         =

The position of the fish with respect to the water's surface at 4:00 pm is feet.

141.73 g

Step-by-step explanation:

Since we are informed that each gram

of salt contains 0.393 g of sodium. The amount of sodium that will be in 55.7g of pure salt will then be calculated as:

= 55.7 / 0.393

= 141.73 g
