A science teacher has 0.4 liter of seawater. She gives each of her 22 students a
container and a 5-milliliter spoon. She then asks her students to put two spoonfuls of
seawater into their containers. How many milliliters of seawater will be left after all
22 students have filled their containers?
70
180
290
780

180

Step-by-step explanation:

.4 liters = 400 milliliters

22 * 10 = 220

400-220 = 180

the circle graph is not a function.

step-by-step explanation:

the graph of the circle is not a function.

because for a graph to be a function, each value of x must give one value of y

in the circle, the values of x for -2< x< 2 each give 2 values of y.

hence this is not a function.
