Answer:
1320
Step-by-step explanation:
This can be solved using something called a permutation. There are 12 possible swimmers that can be in first place. After that, there are 11 swimmers left to be in second place. Finally there are 10 swimmers left for third place. Multiplying these together, you get 12*11*10=1320 ways. Hope this helps!
d₁ = 4 + 4 = 8
d₂ = 3 + 3 = 6
The area of the rhombus:
8 · 6/2 = 8 · 3 = 24 {u²]
First answer.
Let e = your earnings.
Let h = number of hours you work.
Since you earn $20 per hour, the amount you earn is the number of hours times $20, or 20h.
e = 20h
The middle value should be 4%.
The reason why is because if the value inside the parentheses was 1.00, it would be constant. 1.04 is equivalent to a positive change of 4%.
Also, it changes every 1 hour, instead of every 15 minutes, because the function is solving for variable t, which, in this context, represents the time in hours.
It’s 25% because if you divide 100 by 4 you get 25
