I think isn't anyone of these alternatives because if we put number 15 in the place of y it is x-y=30. X-15=30
X=30+15=45.
X=45
Answer:
14.0% increase
Step-by-step explanation:
One formula you can use for this is ...
percent change = ((new value)/(old value) -1) × 100%
= (65/57 -1) × 100%
≈ 0.1403 × 100%
≈ 14.0% . . . . . . the positive sign indicates an increase
Answer:
10500
Step-by-step explanation:
8 times 1000 is 8000
2 times 1000 is 2000
8000 plus 2000 plus 500 is 10500m
Answer:
LN = 15
Step-by-step explanation:
The arrows on the line segments indicate they are parallel.
<u>Triangle Proportionality Theorem</u>
If a line parallel to one side of a triangle intersects the other two sides of the triangle, then it divides these two sides <u>proportionally</u>.
Given:
⇒ LK = JL - JK = 30 - 18 = 12
Substituting the values into the equation and solving for LN:
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
