Step-by-step explanation

Answer:

710

Step-by-step explanation:

Numeration of pages goes from 1.

9 pages with 1-digit numbers, from 1 to 9.

90 pages with 2-digit numbers, from 10 to 99.

So,  2*90 + 9 = 189 digits are just used to numerate 9 + 90 = 99 pages.

The rest of numbers are 3-digit.

2022-189/3 = 611  pages with 3-digit numbers.

Total pages = 9 + 90 + 611 = 710.

The number the pages of a book,2022 digits are used there are 8880 pages in the book.

Let's assume there are "x" pages in the book. Each page number requires a certain number of digits to represent. The number of digits required to represent a page number depends on the value of the page number itself.

For example:

Page numbers from 1 to 9 require 1 digit each.

Page numbers from 10 to 99 require 2 digits each.

Page numbers from 100 to 999 require 3 digits each.

And so on.

Since we're given that 2022 digits are used in total, we can set up an equation based on the above observations:

Number of 1-digit page numbers + Number of 2-digit page numbers + Number of 3-digit page numbers + ... = 2022

Now let's solve this equation to find the number of pages:

Number of 1-digit page numbers = 9 (from 1 to 9)

Number of 2-digit page numbers = 90 - 10 + 1 = 81 (from 10 to 99)

Number of 3-digit page numbers = 900 - 100 + 1 = 801 (from 100 to 999)

Substituting these values into the equation:

9 + 81 + 801 + ... = 2022

Now we need to find the number of terms in this sequence. Each term corresponds to a certain number of digits, and we want to find the smallest number of digits that will exceed 2022. We can try different numbers of digits until we find the correct one:

Number of 4-digit page numbers = 9000 - 1000 + 1 = 8001

Adding the terms up:

9 + 81 + 801 + 8001 = 8880

Answer:

6(3x−4y)

Step-by-step explanation:

well, we know they won 60% of the games, meaning 100% - 60% = 40%, they lost 40% of the games, and we also know that that number is 12.

[tex]\begin{array}{ccll} \%&amount\\ \cline{1-2} 40 & 12\\ 60& x \end{array} \implies \cfrac{40}{60}=\cfrac{12}{x}\implies \cfrac{2}{3}=\cfrac{12}{x} \\\\\\ 2x=36\implies x=\cfrac{36}{2}\implies x=18[/tex]

Step-by-step explanation:

Assuming that no transaction happens in her account for those 2 years, the amount that Brooke will have in 2 years for given case is $8.47

If n is the number of times the interested is compounded each year, and 'r' is the rate of compound interest annually, then the final amount after 't' years would be:

[tex]a = p(1 + \dfrac{r}{n})^{nt}[/tex]

We're specified that:

Thus, we get the final amount's value (after 2 years of compounding) for this case as :

[tex]a = p(1 + \dfrac{r}{n})^{nt}\\\\a = 7(1 + 0.10)^2 = 7 \times (1.1)^2 = 7 \times 1.21 = 8.47 \: (\rm in \: dollars)[/tex]

You can plug in any numbers to both expressions and they will always have the same outcome.

For example, let's plug in 2.

Created Sequences

S1: 10 20 40 80 150

s2:24 20

The first term that appears in both sequences is the second term. Both of them equal 20.

I don't think you have to go any further once you get the first term.

Method

S1: Multiply by 2 starting with 10.

10*2 = 20

20*2 = 40

S2: Start at 24 and subtract 4

24 - 4 = 20

20 - 4 = 16

The equation that represent the amount in the account after t years is A = 100(1.06)^t

This is an interest on an amount of money. The formula for calculating the compound interest is expressed as;

A = P(1 + r)^t

P is the principal = 100

r is the rate = 6% = 0.06

If the interest is compounded annually, the equation that represent the amount in the account after t years is given a:

A = 100(1+0.06)^t
A = 100(1.06)^t

Answer:

[D] −6 < x < 9

Step-by-step explanation:

So, if a < u <b then a < u and u <b

-7 < x - 1 and x -1 < 8

Solving

-7 < x - 1  = x > -6

x - 1 < 8 = x < 9

Combine the intervals

-6 < x < 9

Now looking at the answer choice :

6 < x < 9

−6 > x > 9

6 > x > −9

−6 < x < 9

Thus, the answer is [D] −6 < x < 9
