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

Answer:
can I be marked BRAINLY whatever please
A^2-64=0 you can factor like this:
(a+8)(a-8)=0 and since a>0, a must be 8
or you can do this:
add 64 to both sides of the equation leaving you with:
a^2=64 taking the square root of both sides
a=(-8,+8) and since a>0, a=8
Answer:
5 pigs
Step-by-step explanation:
A farmhouse shelters 16 animals, some are pigs, and some are ducks. Altogether there are 42 legs. How many pigs are there?
Let us represent:
Number of pigs = x
Number of ducks = y
Our system of equations is given as:
A farmhouse shelters 16 animals, some are pigs, and some are ducks.
x + y = 16...... Equation 1
x = 16 - y
Altogether there are 42 legs.
Ducks have 2 legs(feet) , pigs have 4 legs,
4x + 2y = 42..... Equation 2
We substitute
16 - y for x in Equation 2
Hence:
4(16 - y) + 2y = 42
64 - 4y + 2y = 42
Collect like terms
- 4y + 2y = 42 - 64
-2y =- 22
y = -22/-2
y = 11 ducks
Solving for x.
x = 16 - y
x = 16 - 11
x = 5 pigs
Therefore, we have 5 pigs
