Which is the correct way to write 602, 200,000,000,000,000,000,000 in scientific notation?
1 answer:
Scientific notation is
n times 10^x
where 1≤n<10 and x is the number of places the decimal place moved (if it moved to the right, x is negative, if it moved to the left, x is positive)
602, 200,000,000,000,000,000,000.0
we see we need to move decimal to the left 23 spaces to here
6.022 times 10^23
answer is
n times 10^x
where 1≤n<10 and x is the number of places the decimal place moved (if it moved to the right, x is negative, if it moved to the left, x is positive)
602, 200,000,000,000,000,000,000.0
we see we need to move decimal to the left 23 spaces to here
6.022 times 10^23
answer is

Answer:
62.9% in ten years
Step-by-step explanation:
This type of growth corresponds to what is called an exponential growth, since in the expression for the number of students keep including the multiplication of the same factor as the years go by, Let's start by analyzing what happens the first year:
The initial enrollment of 750 is expected to grow by 5%, therefore after one year the enrollment should be:
After one year = Year_1 = 750 + 5% increase =
where we have used the decimal form of 5% as he factor 0.05 multiplying 750 (the initial enrollment) to give the increase.
After the second year, we consider a starting value of Year_1 enrollments that will increase another 5%, which gives: Year_2 = Year_1 + Year_1 * 0.05= Year_1 (1 + 0.05).
So replacing Year_1 by its original expression (750(1+0.05)) we notice that Year_2 = 750 * (1+0.05) * (1+0.05) = 750 * (1+0.05)^2
We can go on with this same reasoning and find that each year includes a new factor (1+0.05) to the new increasing enrollment.
At the end of 10 years, the number of enrollment will be:
which we can round to 1222 students enrolled
This means and increase of:
That is approximately 62.9%
Answer:
the number of black tokens in the bag is 2
Step-by-step explanation:
The computation of the number of black tokens in the bag is as followS
Given that
There is 8 green tokens
and, the ratio of green tokens to black tokens is 4:1
So let us assume the black tokens be x
So,
Now do the cross multiplication
x = 2 tokens
Hence, the number of black tokens in the bag is 2
