The degree is the largest exponent on the variable.
Degree: 5
Answer:
The height of the giraffe is 27.432 decimeters.
Step-by-step explanation:
To convert 1 foot to decimeters you would multiply by 3.048.
We need to multiply 9 feet by 3.048 which would give you the answer of 27.432 decimeters.
Given:
Volume of cuboid container = 2 litres
The container has a square base.
Its height is double the length of each edge on its base.
To find:
The height of the container.
Solution:
We know that,
1 litre = 1000 cubic cm
2 litre = 2000 cubic cm
Let x be the length of each edge on its base. Then the height of the container is:
![h=2x](https://tex.z-dn.net/?f=h%3D2x)
The volume of a cuboid is:
![V=l\times w\times h](https://tex.z-dn.net/?f=V%3Dl%5Ctimes%20w%5Ctimes%20h)
Where, l is length, w is width and h is height.
Putting
, we get
![2000=x\times x\times 2x](https://tex.z-dn.net/?f=2000%3Dx%5Ctimes%20x%5Ctimes%202x)
![2000=2x^3](https://tex.z-dn.net/?f=2000%3D2x%5E3)
Divide both sides by 2.
![1000=x^3](https://tex.z-dn.net/?f=1000%3Dx%5E3)
Taking cube root on both sides.
![\sqrt[3]{1000}=x](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B1000%7D%3Dx)
![10=x](https://tex.z-dn.net/?f=10%3Dx)
Now, the height of the container is:
![h=2x](https://tex.z-dn.net/?f=h%3D2x)
![h=2(10)](https://tex.z-dn.net/?f=h%3D2%2810%29)
![h=20](https://tex.z-dn.net/?f=h%3D20)
Therefore, the height of the container is 20 cm.
The answer of the equation is 18.
Explain: it’s equals to 20
