(Please help if you can!!) The volume of a fish tank is 40 cubic feet. If the density is 0.4 fish over feet cubed , how many fish are in the tank? (1 point) A) 16 B) 4 C) 100 D) 10

Simply do 0.4 * 40 to get the 16 fish

16 fishes

Step-by-step explanation:

First, multiply the volume of the fish tank to the density of the fishes in the tank. By doing this, the cubic feet units will be canceled and what will be left is the number of fishes in the tank.

(0.4 fish / ft³ )(40 ft³) = 16 fishes

when rotating a figure 180 degrees, imagine that you are able to take the figure and turn it clockwise or counterclockwise around a center point. to rotate a figure 180 degrees, you will need to apply the rule (x, y) → (-x, -y). start by using a coordinate grid with coordinates for each vertex of the figure. the center point of the coordinate grid is located at (0, 0), which is what you will rotate the figure around. write down the original coordinates of the shape you are going to rotate. then, apply the rule. for example, coordinate (1, 2) becomes (-1, -2). another example would be, coordinate (-4, -2) becoming (4, 2). after you change each original coordinate to the rotated coordinate, you will draw your new figure.
