Answer:
54 3/5 mi/h
Step-by-step explanation:
To find miles per hour, divide miles by hours.
(18 1/5 mi)/(1/3 h) = (18 1/5)(3/1) mi/h = 54 3/5 mi/h
Round to the nearest:
Ten-thousandths: 0.2745
Thousandths: 0.275
hundredths: 0.27
Tenths: 0.3
Answer:
2 is the extraneous solution
Step-by-step explanation:
Given equation is
Factor the denominator
LCD is x(x-2), multiply all the fractions by LCD
, subtract 8 from both sides
factor the left hand side
x-2=0, so x=2
2x-7=0, 
when x=2, then the denominator becomes 0 that is undefined
So 2 is the extraneous solution
The large triangle and the smaller one are similar. Comparing long sides to short ones, we get
.. (30 mm)/(21 mm) = (14 mm +x)/(14 mm)
.. (14 mm)*10/7 = 14 mm +x
.. (14 mm)*(10/7 -1) = x
.. (14 mm)*(3/7) = x = 6 mm
The value of x is 6 mm.
For this case, the first thing we will do is define the following functions:
Function orange = D (x)
Blue function = D1 (x)
Let's see how one function varies with respect to the other:
D1 (x) = D (x) - 2.5
Therefore, we see that the function decreases.
Answer:
B. A decrease in demand
