Tony purchases 12 water bottles. Of those bottles, 5 hold 400 milliliter each and 7 hold 1.5 liters each. How much water, in milliliter AND liters, does Tony purchase

12 L 500 mL

Step-by-step explanation:

First, multiply the two types of bottles separately.

5 × 400 = 2000 mL

7 × 1.5 = 10.5 L

You can convert the volume of the first from milliliters to liters.  There are 1000 milliliters in 1 liter.  In the second volume, you can convert the decimal to milliters.

2000 mL = 2 L

0.5 L = 500 mL

Add all of the numbers together.

10 L  +  2 L  +  500 mL  =  12 L 500 mL

Tony purchased 12 L and 500 mL of water.

hope it you

step-by-step explanation:

sin(7pi/6 - pi/3)  

= sin(7pi/6 - 2pi/6)  

= sin(5pi/6)  

= sin(pi - pi/6)  

= sin(pi/6)  

= 1/2  

sin 7pi/6 - sin pi/3  

= sin (pi + pi/6) - sin pi/3  

= -sin pi/6 - sin pi/3  

= -1/2 - sqrt(3)/2  

= -(1+sqrt(3))2

the answer is (-4,-4)
