Answer:
Step-by-step explanation:
AB = a
AP = 2PQ = 2QB
AB = AP + PQ + QB
= AP + 
+
AB = 2AP
AP = 
-----(1)
And we know QB =
QB= AP/2 = 
---------(2)
Now midpoint of AP = × 
=
and midpoint of QB = × =
distance between these midpoints = -
=
Answer:
Revolution = 127.24 revolutions
Step-by-step explanation:
<em><u>Circumference of the tire = πD</u></em>
Where D = 15 inch
So,
C = 15π = 47.1 inch
<u><em>In feets:</em></u>
47.1 inch = 3.93 feet.
So, <u>one revolution = 3.93 feet</u>
<u><em>Travelling 500 feet will make the following revolutions:</em></u>
Revolution = 500 feet/3.93 feet
Revolution = 127.24 revolutions
Answer:
The answer is B
the shaded part is below which signifies a less than sign
so you can cross out options A and C
now make y=0
for option B, it will give √Xless than or equal to √4
for option D, it will give √4 less than or equal to √x
to bring √x to the other side, the inequality sign will change to greater than
Therefore the answer is B
