Answer:
3,258
Step-by-step explanation:
first multiplay 49.20 with 30
=1,476
then multiply 59.40 with 30
=1,782
then add them together
1476+1782=3258
This is essentially the game mastermind if you want to look up more about it
the first 2 guesses have a number with the correct value and in the right position "bulls", all three guesses start with a 1, so if 1 were correct in the first position the 3rd guess would have a "bull" too
this means either the 6 or 2 from the first guess and the 7 or 5 from the second are correct in the 2nd or 3rd position
in the 3rd guess the 3rd number is a 5 without a "bull" so the 5 in the 2nd guess can't also be the "bull". Because 1 and 5 can't possibly be bulls the only number left is 7 so the code is _7_
Because of this we also know that in the first guess the 2 must be the "bull", as in the second spot only a 7 would be correct and the 1 is incorrect anyways -> the code is _72
"Cows"=right number at wrong position only appeared in the guesses 2 and 3 and we know it's neither the numbers 1 (because of guess 1), 7 (becuse it is a bull in 2) and 6 (because it is only in 3 and not both 2 and 3) -> the only number in guess 2 and 3 left is 5
-> the code is 572
Answer:
Step-by-step explanation:
Alright, lets get started.
We first assume that Alfonso's bicycling speed with no wind is = x miles per hour
With the wind, his speed will be = miles per hour
Against the wind, his speed will be = miles per hour
For traveling 54 miles with the wind, the time will be =
For traveling 30 miles against the wind, the time will be =
Alfonso found that both the timings are same, so
Cross multiplying
Solving for x
Dividing 24 in both sides
So, Alfonso's normal bicycling speed with no wind is 14 miles per hours. : Answer
Hope it will help :)
Answer:
1.41
Step-by-step explanation:
