Yes, this is certainly ugly and scary.
Here's how to go about it:
-- Take the two resistors in the middle ... the 9 and the 8 .
They're in parallel.
Their equivalent resistance is something like 4.24 ohms. Whatever.
-- Take the two resistors around the outside on the right ... the 4 and the 6 .
Together, in series, they're equivalent to 10 ohms.
-- That 10 ohms is in parallel with the ~4.24 ohms in the box.
Now you have something like 2.98 ohms, all to the right of the 3 on top.
-- That 2.98 is in series with the 3.0 on top.
So there's 5.98 ohms.
-- The 20.0 is in parallel with the 5.98 ohms.
So that's about 4.6 ohms equivalent between 'A' and 'B'.
That's just off the top of my head. I won't sharpen it down
any further than that, because it's only 5 points, and you
should be able to do it now, using this approach.
Answer:
Average velocity = 30 miles per hour
Explanation:
Given that
Velocity for uphill = 20 miles per hour
Velocity for downhill = 60 miles per hour
We know that
Distance = Velocity x time
Total distance = Average velocity x total time
Lets take distance from home to school is s
Time taken from home to school= s/20 hr
Time taken from school to home= s/60 hr
Total time =s/20+s/60
Total distance = Average velocity x total time
s + s = Average velocity x (s/20+s/60)
So average velocity = 30 miles per hour

thats the answer because it actually
increase rish of heart attack

B: 210.8 rounded to 210 is totally wrong, and the reason why is because 210.8 rounded to the nearest whole number is 211, not 210. So B is the one with the error (this option is correct) and the other user that said D, is wrong since 18.42 does round to 18.4.
Hope this helped!
