Answer: (4, 3)
Step-by-step explanation:
The formula for coordinate of the mid point is given as :
Mid point = (
, 
)
= 9
= -1
= 9
= -3
Substituting the values into the formula , we have :
Mid-point = (
, 
)
Mid-point = ( 
, 
)
Mid - point = ( 4 , 3)
Answer: 3.1
Step-by-step explanation:
100%/x%=300/60(100/x)*x=(300/60)*x - we multiply both sides of the equation by x100=5*x - we divide both sides of the equation by (5) to get x100/5=x 20=x x=20
now we have: 60 is 20% of 300

In thermodynamics, specific volume is considered to be an
intrinsic property of matter. What we meant by intrinsic property is that, the
value of this property does not change no matter the size of the sample. This
is opposite to weight or volume which changes depending on the size of the
sample.
By mathematical definition, specific volume is the ratio of
the substance’s volume to its mass. Or in other words, this is the reciprocal
of density.
The formula for density is:
density = mass / volume
Since specific volume is reciprocal so:
Specific volume = 1 / density = volume / mass
Calculating:
Specific volume = 100 ft^3 / 5 pounds
Specific volume = 20 ft^3 / pound
Or when asked in units of m^3 / kg, we convert:
Specific volume = (20 ft^3 / pound) (2.2 pound / kg) (1 m^3
/ 35.3147 ft^3)
Specific volume = 1.246 m^3 / kg
