a laboratory, you determine that the density of a certain solid is 5.23×10−6kg/mm3. Convert this density into kilograms per cubi

Vedmedyk [2.9K]

Answer:

$5.23\times 10^{-6}\ kg/mm^3=5230\ kg/m^3$

Step-by-step explanation:

Given : The density of a certain solid is $5.23\times 10^{-6}$ kg/mm³.

To find : Convert this density into kilograms per cubic meter ?

Solution :

We know that,

$1\ m^3=10^9\ mm^3$

or $10^9\ mm^3=1\ m^3$

So, $1 mm^3=\frac{1}{10^9}\ m^3$

$1 mm^3=10^{-9}\ m^3$

Converting $5.23\times 10^{-6}$ kg/mm³ into kg/m³,

$5.23\times 10^{-6}\ kg/mm^3=\frac{5.23\times 10^{-6}}{10^{-9}}\ kg/m^3$

$5.23\times 10^{-6}\ kg/mm^3=5.23\times 10^{-6+9}\ kg/m^3$

$5.23\times 10^{-6}\ kg/mm^3=5.23\times 10^{3}\ kg/m^3$

$5.23\times 10^{-6}\ kg/mm^3=5230\ kg/m^3$

Therefore, $5.23\times 10^{-6}\ kg/mm^3=5230\ kg/m^3$

What is the value of the expression below when w = 8 and x = 4? 9w + 5x

Ne4ueva [31]

Answer:

Step-by-step explanation:

If w=8 then you would multiply 9 by 8 which is 72. Then you would multiply 5 with 4 since x equals 4 which is 20. Then you would add 72+20 which gives you your answer which is 92
