How many ways can 12 swimmers finish in first , second, and third place?

Burka [1]

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!

Shiyun bought a car in 1999. The value of the car V , in USD, is depreciating according to the exponential model

Anastaziya [24]

Hi there

a) the value of the car is 25000

b) v=25,000×1.5^(−0.2×3)=19,601

C) 12500=25000×1.5^(-0.2t)
Solve for t
12500/25000=1.5^(-0.2t)
Log (12500/25000)=-0.2t×log (1.5)
-0.2t=Log(12500/25000)÷log (1.5)
T=(log(12,500÷25,000)÷log(1.5))÷(−0.2)
T=8.55 years

Hope it helps

Johanna, Elizabeth, and Dan are preparing a chemical solution for a research project. When

Bond [772]

Using the together rate, it is found that they would prepare the solution in 1.71 minutes working together.

<h3>What is the together rate?</h3>

It is the sum of each separate rate.

In this problem, the rates are given by:

Johanna's: 1/6.

Elizabeth's: 1/6.

Dan's: 1/4.

Hence the together rate is given by:

$\frac{1}{x} = \frac{1}{6} + \frac{1}{6} + \frac{1}{4}$

$\frac{1}{x} = \frac{1}{3} + \frac{1}{4}$

$\frac{1}{x} = \frac{4 + 3}{12}$

7x = 12

x = 12/7

x = 1.71.

They would prepare the solution in 1.71 minutes working together.
