Answer:600 miles
Step-by-step explanation:
Hello!
So you know that 348 miles is equal to 58% so you want to figure out what 1% of the total trip is
348 / 58 = 6
You know that 1% of the trip is 6 miles so now to figure out what the total trip is you multiply 6 by 100
6 * 100 = 600
So you know that the total length of the trip is 600 miles long.
Answer:

Answer to 14C3 is 364
Step-by-step explanation:
14! = 14*13*12*11*10*9*8*7*6*5*4*3*2*1
14C3 = 14*13*12*11*10*9*8*7*6*5*4*3*2*1 / 3*2*1 * 11*10*9*8*7*6*5*4*3*2*1
= (14*13*12) / 3*2*1
= 14*13*2
= 364
