A metal hollow bar whose cross section and dimension are shown below weighs 8x10^3 kg/m^3 and measure 2m in length ..determine t
devlian [24]
1) We calculate the volume of a metal bar (without the hole).

volume=area of hexagon x length
area of hexagon=(3√3 Side²)/2=(3√3(60 cm)²) / 2=9353.07 cm²
9353.07 cm²=9353.07 cm²(1 m² / 10000 cm²)=0.935 m²

Volume=(0.935 m²)(2 m)=1.871 m³

2) we calculate the volume of the parallelepiped

Volume of a parallelepiped= area of the section  x length
area of the section=side²=(40 cm)²=1600 cm²
1600 cm²=(1600 cm²)(1 m² / 10000 cm²=0.16 m²
Volume of a parallelepiped=(0.16 m²)(2 m)=0.32 m³

3) we calculate the volume of a metal hollow bar:
volume of a metal hollow bar=volume of a metal bar -  volume of a parallelepiped

Volume of a metal hollow bar=1.871 m³ - 0.32 m³=1.551 m³

4) we calculate the mass of the metal bar

density=mass/ volume  ⇒ mass=density *volume

Data:
density=8.10³ kg/m³
volume=1.551 m³

mass=(8x10³ Kg/m³ )12. * (1.551 m³)=12.408x10³ Kg

answer: The mas of the metal bar is 12.408x10³ kg  or   12408 kg

Rewrite 19/19 as a whole number
Elis [28]

The answer is 1.

Because if you simplify (divide) 19/19 you get one.

4/4 would also be 1.  Any number divided to itself will always be 1.

Whereas 30/15 would be 2 because thirty divided by fifteen is 2

Write as an expression: a number that is equal to twice as much as x
lesantik [10]

Let's call the number we're looking for y. We know that y is twice as much as x.


Twice as much as a number simply means the double of that number, and in turn the double of a number means to muliply that number by 2.


So, in order to obtain y, you have to multply x by 2. In formula, you have


y = 2\cdot x or simply y = 2x
