0.4 liter means 400 ml (milliliter).

We know that 1 spoon is 5 ml. Thus, if each student takes out 2 spoons, then each student will take out 10 ml of water.

There are 22 students, so each student will take out 220 ml.

Thus, the milliliters of seawater that will be left after all 22 students have filled their containers is:

400-220=180 ml

400ml \div 10ml = 40ml \\ 40ml - 22ml = 18ml
so the answer is 18milliliters

The coefficient of xy in the product of (4x^2+2y) and (3x+y^2) is ...
LUCKY_DIMON [66]
Here is your answer! The coefficient of xy is 6. To solve this problem, you need to multiply your two polynomials together. I used the FOIL Method- multiply the First two, the Outside two, the Inside two, and the Last two. You can see how I did it on the picture attached. Next, the answer that you get as a result from FOILing is your polynomial. If you look at the number before xy, that is the coefficient. A coefficient is a number that is right before and attached to a variable. I hope this helps you! :))
