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.

d 25 pi/6

step-by-step explanation:

the diameter is 10 inches

the radius is 1/2 of the diameter or 5 inches

the area of the circle is

a = pi r^2

  = pi 5^2

  = 25 pi

the slice is 60 degrees of the entire circle.

60 degrees out of 360   60/360 = 1/6

the area of the slice is 1/6 of the circle

a slice = 1/6 a circle

a slice = 1/6 * 25 pi
