Answer:
7 cards.
Step-by-step explanation:
60-39.5=20.5, that's what he has left if he buys 5 cards.
so, if you buy 2 more cards, that would be 18 dollars so 20.5-18=2.5
5 cards+ 2 cards= 7 cards.
He still hzs 2.5 dollars left

Answer:
x = (2 i π n)/log(4) + log(2 sqrt(2))/log(4) for n element Z
Step-by-step explanation:
Solve for x:
2 sqrt(2) = 4^x
Hint: | Reverse the equality in 2 sqrt(2) = 4^x in order to isolate x to the left hand side.
2 sqrt(2) = 4^x is equivalent to 4^x = 2 sqrt(2):
4^x = 2 sqrt(2)
Hint: | Eliminate the exponential from the left hand side.
Take the logarithm base 4 of both sides:
Answer:x = (2 i π n)/log(4) + log(2 sqrt(2))/log(4) for n element Z
50 m/s is going to be 180 km/h or 3 km/s.
50 / 1000 = 0.05
0.05 x 60 = 3 kilometers a minute.
3 x 60 = 180 kilometers an hour.
50 m/s divided by 1 kilometer = 0.05 kilometers a second. You then multiply it by 60 to get it in minutes, and then 60 again to get it in hours. because their are 3600 seconds in an hour. So you could divide 50 meters per second by 1000 meters or 1 kilometer and then multiply it by 3600 seconds to get 180 kilometers an hour.
