Step-by-step explanation:
I think it is $4,821 because that is what I got as an answer. I hope this helped!
This is an easy half-life calculation because it involves an exact integer of half-lives. 1,104 days is precisely 8 half-lives. After each half-life, one half of the original remains.
So, after 8 half-lives you will have 1 / 2^8 of the original material left.
So we start with 30 grams and 1 / 2^8 =

We are therefore left with (30 *

0.1171875 grams of the original 30 grams of polonium.

To solve this problem you must apply the proccedure shown below:
1. You have the following information given in the problem above:
- Mount Mckinley is 20,320 feet above sea level.
- Mauna kea is 13,796 feet above sea level.
2. Then, you only need to substract both quantities to solve the exercise, as following:
Therefore, as you can see, the answer is: 6,524 feet.
Given:
Wang Yong owes the bank $8500. He pays back a fixed amount each month. After 12 months, he still has to pay off $6460.
To Find:
The amount of money he pays the bank every month and how long it will take him to pay off the full debt.
Answer:
Wang Yong pays $170 each month, and doing so, it will take him a total time of 50 months to pay off the full debt.
Step-by-step explanation:
Wang Yong has borrows $8500 according to the question.
Say he pays the bank an amount of x every month, which is fixed. After 12 months, he still has to pay $6460.
In 12 months, he would have paid the bank 12x.
But $6460 is still left out of the original $8500.
This means,
That is, Wang Yong pays the bank $170 every month.
Next, to calculate the amount of time it took Wang Yong to pay back his whole debt, we divide the total sum of money owed to the bank by the amount Wang Yong pays each month.
So, number of months = 8500 ÷ 170 = 50
That is, Wang Yong will pay off his debt 50 months after borrowing the money from the bank, provided he pays back $170 every month.
