I think (C):600
Explained: other sources say there is about 650 but if you count the muscles within a complex muscle then about 840
Answer:
a+4b
Explanation:
Since the length is 4a-2b, that means there is 2 of those, since the perimeter is 2l+2w, which basically means 2 values of the length plus 2 values of the width. In this case, the length is 4a-2b so that means we have to subtract twice its value from the perimeter, 10a+12b.
When you do that, you get 2a+8b, which must be divided into 2 because there is supposed to be 2 values of the width. That gets you your final answer, a+4b.
The answer is B because a virus would be more effective
The safety catch for the 4th wheel locking lever must be over the locking lever for coupling to be complete.
What is the importance of coupling?
- If needed, use a flashlight.
- A void between the top and lower fifth wheels must not exist.
- If there is room, there is a problem (kingpin may be on top of closed fifth wheel jaws; trailer would come loose very easily).
- Look into the fifth wheel's back by crawling underneath the trailer. Make sure the kingpin's shank is enclosed by the fifth wheel's jaws
- Ensure that the locking lever is set to "lock."
- Verify that the safety latch is over the locking lever. (On some fifth wheels, the latch needs to be manually installed.)
- Drive the linked unit sparingly if the coupling needs to be repaired.
Hence the answer is over the locking lever.
