This is true.
for example, if line a has a slope of 1/2 then line b (which is perpendicular) has a slope of -2.
Total teams = 64
After round 1, teams remaining = 64 ÷ 2 = 32
After round 2, teams remaining = 32 ÷ 2 = 16 = or (64 ÷ 2^2 = 16)
After round n, teams remaining = 64 ÷ (2^n)
Let after n rounds, teams remaining = 2
=> 64 ÷ 2^n = 2
=> 64/(2^n) = 2
=> 64/2 = 2^n
=> 32 = 2^n
=> 2^5 = 2^n
=> n = 5
Thus, after round 5, two teams will remain.
Answer:
143.29
Step-by-step explanation:
20,000 for 20 yr at 6% intrest
240 total payments with total intrest of 14,388.69
payback amount 34,388.69
Answer:
a. 45 + 20x
30 + 26x
b. 2.5 hours
c. 95
Step-by-step explanation:
45 + 20x = 30 + 26x
subtract 30 from both sides of the equation
15 + 20x = 26x
subtract 20x from both sides of the equation
15 = 6x
divide 6x on both sides of the equation
2.5 = x
