Answer:
3770 mm.
Step-by-step explanation:
The diameter of of the wheels is 60mm, that means the radius is 30mm.
Now for one revolution of the wheels, they cover the distance of 
on the ground.
For 20 revolutions, the distance covered will be 20 times this.
Thus
Which is our answer.
Answer:
116
Step-by-step explanation:
To find f(12), plug in 12 as x in the equation:
f(x) = 2/3x + 9x
f(12) = 2/3(12) + 9(12)
f(12) = 8 + 108
= 116
So, f(12) = 116
Answer:
The problem in the first statement is that it does not say that the lines must be in the same plane.
Suppose in a 3D coordinate axis two lines as:
z = 0, y = 0 (this is the x-axis)
y = 1, x = 0 (this line is parallel to the z-axis but one unit above).
Those two lines are not parallel, and also never meet, so the definition is wrong.
The actual definition should be:
"Parallel lines are two lines that lie on the same plane and never meet"
B: The undefined terms are point, line, plane,...
An example can be "Plane", because if our lines do not lie on the same plane, then we can not use the concept of "parallel lines".

Answer:
D. 23i.
Step-by-step explanation:
(26 + 16i) − (26 − 7i)
Using the distributive law this becomes:
26 + 16i - 26 + 7i
Adding like terms:
= 0 + 16i + 7i
= 23i (answer).
