If i have a jar 600ml and i add the water from this measuring cylinder to 3.6 liters of water. how much water do i now have altogether?

If the cylinder already has 3.6 Liters in it, adding 600 mL would make the cylinder have 4.2 Liters of water in it.

We know this because 600 mL converted to Liters equals 0.6 L. So 3.6 L + 0.6 L = 4.2 Liters.

2⊂3

Step-by-step explanation:

If the ratio is 2:3 and you are using 60mL of concentrate how much water should you add?

If there is 20% concentrate in a 1.25L drink how many millilitres of concentrate is that?

If a drink is made to a ratio of 1:4 how many millilitres of concentrate would you expect in a 250mL glass of drink?

Show the students a 300mL of drink made using a ratio of 1:4. Ask the students how many millilitres of concentrate are in the bottle? It may be useful to draw a diagram of this

d

step-by-step explanation:

d

since your problem is x^4 = 81, what you have to undeo is the "to the fourth power" part.

the inverse (opposite operation) of "to the fourth power" is "to the fourth root".

  (x^4) ^ ¼   = 81 ^ ¼  

  81 = 3^4     so (3 ^ 4) ^ ¼   =   3 ^ 1   = 3

by hand: (3 ^ 4) ^ ¼   =   3 ^ (4 x ¼) = 3 ^ 1   = 3   (when you take a power to a power, multiply the exponents.)

or, do it by calculator. one way of finding the fourth root is to use ^ (1/4)
