Create a conversion factor from "<span>There are 6.02 × 10^23 atoms in 1 gram of hydrogen:"

6.02*10^23 atoms
-------------------------
          1 gram

Then mult. 800 grams by this conversion factor:

</span>6.02*10^23 atoms      800 grams
------------------------- * ----------------
          1 gram                     1

This comes out to 4816*10^23 atoms, which, in scientific notation, is 

4.816*10^26 atoms.

What is 50 points decreased by 26%?
topjm [15]
50 points decreased by 26% is 37, because to find the percentage, all you have to do is multiply the number you are trying to decrease the percentage of, and take the percentage as a decimal form and multiply the two. Then, you have to subtract that number from the base to get your final answer. :)

Mia is 7.02576 × 10^6 minutes old. Convert her age to more appropriate units using years, months, and days. Assume a year has 36
Naya [18.7K]

Answer:

Number of days = 4879 days

Number of months = 162.63 months

Number of years = 13.37 years

Step-by-step explanation:

Given

Mia's age (in minutes) = 7.02576 * 10^6

Required

Calculate age in years, months and days.

For ease of work, we'll start by converting to days.

First, it should be noted that there are 24 hours in one day

And there are 60 minutes in an hour.

This means that there are 24 * 60 minutes in a day

Number of minutes = 24 * 60 minutes

Number of minutes = 1,440 minutes

So, if number of minutes in a day is 1,440

Number of days in 7.02576 * 10^6 minutes is calculated as follows

Number of days = \frac{7.02576 * 10^6}{1440}

Number of days = 4879 days

Now, we can convert this to month and year, easily.

From the question, it should be assumed that there are 30 days in a month.

If 1 month = 30 days

Then, there are \frac{4879}{30} months in 4879 days

Number of months = \frac{4879}{30}

Number of months = 162.63 months

Converting to year

From the question, it should be assumed that there are 365 days in a month.

If 1 year = 365 days

Then, there are \frac{4879}{365} years in 4879 days

Number of years= \frac{4879}{365}

Number of years = 13.37 years

How do you simplify the answer for 185/200
butalik [34]

Answer:

37/40

Step-by-step explanation:

Divide by 5 to both numbers, since they both end in a 0 or 5.

185/5= 37

200/5= 40

I believe this is your answer since it cannot be simplified anymore.

If f(x) = 1/6 x-8, then f^-1(x)=
bezimeni [28]

Answer:

f^-1(x) is 6x + 48

f(x) = 1/6x - 8

To find f^-1(x) equate f(x) to y

That's

f(x) = y

y = 1/6x - 8

Next interchange the terms

We have

x = 1/6y - 8

Make y the subject

Multiply through by 6

We have

6x = y - 48

y = 6x + 48

Therefore f^-1(x) is 6x + 48

Hope this helps you
