Assuming that you're talking about a standard deck of 52 cards, there are 4 tens and 4 aces.
So, at the beginning, you have probability 4/52=1/13 to draw a ten.
You replace, and you have an identical probability to draw an ace (you still have 4 favourable cases over 52 total cases).
Multiply the two probabilities to find the answer:

80 feet; (use Pythagorean Theorem: leg^2 + leg^2 = hyp^2 )
Answer:
126$
Step-by-step explanation:
A: 6c=75 If there were 6 movies then 6 times the cost of each movie would equal 75.
B:$12.50 We divide 75 by 6.
C: d+75=100 the cost left on the card plus 75 will equal 100.
D: $25 We subtract 75 from 100
