Answer:
Word problems with linear equations (that is, with straight-line models) almost always work this way: the slope is the rate of change, and the y-intercept is the starting value.
Step-by-step explanation:
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
Answer:
11
Step-by-step explanation:
m+10=21
collect like term
m=21-10
m=11
L = 4w
4w + w + w + 4w = 60
10w = 60
w = 6
4w = 24
L = 24
(just to check the answer, 24 + 24 + 6 + 6 = 60 :)
Answer:
Where the graphs intersect is the solution to the system of equations
Step-by-step explanation:
Where the graphs intersect is the solution to the system of equations
The points of intersection is the solution to the system of equations. If they do not intersect, there is no solution
