Let the distance be x miles
Time = Distance / speed
Time taken by Mike to go to his friend's house = x / 40 hours
Time taken by him to return = x / 45 hours
Total time = x / 40 + x / 45 = 4 hours
= 9x + 8x = 1440 miles
17x = 1440
= x = 1440 ÷ 7
= x = 84.706
Time taken to return home = 84.706 /45= 1.882 hours .
Therefore , Mike took 1.882 hours to reach home .
hello since we are simplifying 15^-3*15^6 all we have to do is add the exponents when we add them we end up with an answer of 15^3
Answer:
12.5 and then 6 percent would probably be 12 dollars 80 cents
Step-by-step explanation:
Step-by-step explanation:
From a, the original number is 100x the new number.
So,if the new number is 1unit --> the original is 100x 1unit --> 100units
Add the two numbers together --> 1unit + 100units --> 101 units
We also know that the difference between the two numbers is 136.62
So 100units - 1unit --> 136.62
99units -> 136.62
1unit --> 1.38
101units --> 139.38
