Fair enough! In that case Landry's reply is correct.
Hmm! I'm inclined to think that the credit card balances should be subtracted from the bank balances as, presumably, Lynn will have to pay the former to the credit card companies.
This graph should help
.
Use the fact that tan(68°) = height/14.3, so:
height = 14.3*tan(68°) m
This is the number of distinct ways. Distinct means if you interchange the positions of two of the A's (for example) the result doesn't count as a new arrangement.
11 letters in all.
3 A's; 2 L's; 2 S's; 2 E's
Number of ways = 11!/(3!*2!*2!*2!) = 831600
This graph should help you to answer:
First multiply all terms by 4/3:
x^2 + 2x = 16/3
Add 1 to both sides
x^2 + 2x + 1 = 1 + 16/3
This becomes
(x + 1)^2 = 19/3
There are two solutions:
A. x + 1 = sqrt(19/3) so x = -1 + sqrt(19/3)
B. x + 1 = -sqrt(19/3) so x = -1 - sqrt(19/3)
Match the proportions: x/4 = 2/5 where x is the required number of tablespoons
Multiply both sides by 4: x = 4*2/5 or x = 8/5 or x = 1.6 tablespoons
circumference = 2pi*r where r is radius, so r = circumference/(2pi)
area = pi*r^2
So area = pi*(circumference/(2pi))^2
Hence: circumference = 2pi*sqrt(area/pi)
Can you take it from here?
