Lester and Ralph work at an athletic shoe store in the mall, but whenever they goof off too much, their boss punishes them by making them lace-up all the inventory. I f it takes Lester 30 seconds to lace up a high top and Ralph 35 seconds to do the same, how many seconds will it take them to lace-up 260 high tops?

4200

Step-by-step explanation:

Time taken by Lester 30 seconds

Time taken by Ralph = 35 seconds

Their rate :

Lester = 1/time taken = 1/30

Ralph = 1/ time taken = 1/35

Combined rate:

1/30 + 1/35 = (35 + 30) / 1050 = 65 / 1050 = 0.0619047 per boot

Time taken = number of boots / combined rate per boot

Time taken = 260 / 0.0619047

Time taken = 4200 seconds

ou would have 12 of each

median is the value separating the higher half of a data sample, a population or probablity distribution from the lower half.

step-by-step explanation:

say you have 3,8,7,3,1,9,8 order them from lowest to highest

if orderd it would be 1,3,3,7,8,8,9 now you take away from the lowest and the highest until you end up in the middle.

so you would remove the 1 and 9 leaving you with 5 digits remaining

when you've reached the middle that would be your answer so in this case the answer is 7

if there were two numbers left say 7 and 5 you'd and them together so 12 then divide by 2 witch would equal 6 so the answer would be 6

good luck on that project hoped i you at all
