Layton has two hamsters. Each hamster drinks 3 centiliters. He fills a water bottle that holds 16 centiliters of water. How many centiliters of water are left in the water bottle at the end of the day?

10 centiliters

Step-by-step explanation:

Given data:

2 hamsters are available

1 hamster drinks 3 centiliters

16 centiliters are put

1 hamster drink 3 centiliters therefor 2 hamsters drinks (3 * 2) centiliters = 6 centiliters

Assuming 1 hamster drinks 3 centiliters a day

Remaining centiliters of water will be (16 - 6) = 10 centiliters.

area of part 1:

a1=base*height/2=(8+2)*(8-2-2-1)/2=10*3/2=15 ft^2

area of part 2:

a2=length*width=(8+2)*1=10 ft2

area of part 3:

a3=length*width=8*2=16 ft2

total shaded area : a1+a2+a3=41 ft2

total area of the reactangle : a=16*8=128 ft2

total area of the nonshaded region : 128-41=87 ft2

there are infinitely many solutions.
