Ok the formula for this is 2(lw +hw+hL)

2(30+35+42)=2(107)=214 square feet

We know that

<span>A vessel full of water weighs 16.5kg

</span><span>when the vessel is half full, it weights 10.5kg

so

16.5 kg-10.5 kg=6 kg is the weight of half water

the weight of full water=6kg*2------> 12 kg

so

the weight of the vessel=</span>A vessel full of water-the weight of a full water

the weight of the vessel=16.5 kg-12kg=4.5 kg

**the answer is**

**the weight of the vessel is 4.5 kg**

<span>

**Answer:**

i dont know

**Step-by-step explanation:**

**Answer:**

(2,5)

or x=2, y=5

**Step-by-step explanation:**

3x+2y=16

substitute y =x+3 every place you see a y

3x + 2(x+3) = 16

distribute

3x + 2x +6 = 16

combine like terms

5x+6 = 16

subtract 6 from each side

5x+6 -6 =16-6

5x =10

divide by 5

5x/5 = 10/5

x = 2

now we need to find y

y = x+3

y = 2+3

y=5

(2,5)

or x=2, y=5
