Answer:
221 minutes
Step-by-step explanation:
His goal is 8 minutes or less for every mile during the marathon.
8 x 52 = 416
That gives him 416 total minutes to complete the marathon goal.
He already ran the first half in 195 minutes, so we do this to find the time for the other half:
416 - 195 = 221
He has 221 minutes in the second half of the marathon to meet his goal.
Answer:
Step-by-step explanation:
Work done is given by
, where d = length of cable and w = weight of cable.
Here, d = 175 ft and w = 3 lb/ft
Now,
Since you are given the area, we can solve for radius with this equation:
The radius is 11, so the diameter must be 2 times that, which is 22. With the correct units, the answer is
22 units²
Well if C=1.3m , we substitue 18 into M and get C=1.3(18)= 234
so 234cm
