Answer:

The quantity we sold more than the competitors is 161.

What are percentages?

Percentage can be described as a fraction out of an amount that is usually expressed as a number out of hundred.

How much more did we sell?

Quantity sold more = percentage sold more x number sold by competitors

Mr. Davis invested $8,000 in a savings account. The bank pays 4.5% annual compound
interest. Mr. Davis never withdrew nor deposited in the savings account. Which of the
following exponential graphs represents the money y that Mr. Davis has after x years

Answers

Answer:

Compound interest formula

[tex]\sf A=P(1+\frac{r}{n})^{nt}[/tex]

where:

A = final amountP = principalr = interest rate (in decimal form)n = number of times interest applied per time periodt = number of times periods elapsed

Given:

A = yP = $8,000r = 4.5% = 0.045n = 1t = x

Substitute given values into the equation:

[tex]\implies y=8000(1+\frac{0.045}{1})^x[/tex]

[tex]\implies y=8000(1.045)^x[/tex]

So the graph will have a y-intercept of (0, 8000)

To number the pages of a book,2022 digits are used. How many pages are in the book?

Answers

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

Find the point on the line -5x + 7y - 4 = 0 which is closest to the point (2,3).

Answers

Answer:

  (x, y) = (2 35/74, 2 25/74)

Step-by-step explanation:

The closest point on the line to the given point will be the point of intersection of the given line and a perpendicular through the given point.

__

A line perpendicular to ax+by+c=0 that goes through point (h, k) can be written as ...

  b(x-h) -a(y-k) = 0

For the given line and point, the perpendicular line will be ...

  7(x -2) +5(y -3) = 0

  7x +5y -29 = 0

Using the cross-multiplication method, we can find the solutions to the system of equations consisting of these two lines. It will be ...

-5x +7y -4 = 07x +5y -29 = 0

  Δ = (-5)(5) -(7)(7) = -74

  Δx = (7)(-29) -(5)(-4) = -183

  Δy = (-4)(7) -(-29)(-5) = -173

  x = Δx/Δ = -183/-74 = 2 35/74 ≈ 2.4730

  y = Δy/Δ = -173/-74 = 2 25/74 ≈ 2.3378

Find two pairs of prime numbers less than 20 that differ by 4

Answers

Answer:

3 and 7,

7 and 11,

13 and 17

Step-by-step explanation:

Prime numbers have exactly two factors, the number itself and 1. This just means that nothing "goes into" these numbers. Example: 7. 7 is a prime number; the only number that goes into 7 is 7 (and 1)

First, find all the prime numbers that are less than 20:

2, 3, 5, 7, 11, 13, 17, 19

Next find the pairs that are 4 units apart. 3 and 7 works.

7 - 3 is 4

Also, 13 and 17 works, and 7 and 11.

Rosie went on a hiking trip. The first day she walked 18 kilometers. Each day since she walked 90% of what she walked the day before. What is the total distance Rosie has traveled by the end of the 10th day?

Answers

Answer:

Rosie has walked 163.8 kilometers by the 10th day,

Step-by-step explanation:

We know that the first day is 18 kilometers.

90% = 0.9

0.9 x 18 = 16.2

There are 9 more days

16.2 x 9 = 145.8

Now we add the first day

145.8 + 18= 163.8

What is the domain and range!!
PLEASE HELP I WILL BE GIVING OUT MORE POINTD AND MARKED BRAINIST ONLY IF YOU ARE RIGHT THO I DO CHECK !!

Answers

Recall that domain is in x axis

Thus from the graph we can see,

the domain is  x ≥ -1   and x ≤ 3

Thus final domain: -1 ≤ x ≤ 3

Answer:

[tex]\textsf{domain:}\quad-1\leq x\leq 3[/tex]

[tex]\textsf{range:}\quad\dfrac{16}{3}\leq y\leq 27[/tex]

Step-by-step explanation:

Information

Domain of a function: set of all possible input values (x-values)

Range of a function: set of all possible output values (y-values)

Closed circle:  less than or equal to and greater than or equal to (≤ or ≥).

Open circle: less than or greater than (< or >)

Domain

There is a closed dot at x = -1 and x = 3

Therefore, the domain is -1 ≤ x ≤ 3

Range

To calculate the exact range, we need to figure out the equation of the function (as it is difficult to read the exact value of y at x = -1).

From inspection of the graph, we can identify the following ordered pairs:

(1, 12)  (2, 18)  (3, 27)

General form of an exponential equation: [tex]y=ab^x[/tex]

Inputting the first two ordered pairs into the exponential equation:

[tex]\implies ab^1=12[/tex]

[tex]\implies ab^2=18[/tex]

Dividing the equations to find b:
[tex]\implies \dfrac{ab^2}{ab^1}=\dfrac{18}{12}[/tex]

[tex]\implies b=\dfrac32[/tex]

Inputting b into the first equation to find a:

[tex]\implies \dfrac32a=12[/tex]

[tex]\implies a=8[/tex]

Therefore, the equation of the function is: [tex]y=8\left(\dfrac32\right)^x[/tex]

Input  [tex]x = -1[/tex]  into the equation to find y:

[tex]\implies 8\left(\dfrac32\right)^{-1}=\dfrac{16}{3}[/tex]

Therefore, the range is [tex]\dfrac{16}{3}\leq y\leq 27[/tex]

The rectangle of the rectangle is shown 44m squared. Find out the missing length of x

Answers

Answer:

12 m

Step-by-step explanation:

3 ⅔

= 9/3 + 2/3    { LCM = 3 }

= ( 9 + 2 ) / 3

= 11/3

In the diagram,

Length ( l )= x m

Breadth ( b ) = 3 ⅔ m = 11/3 m

Given that area of the rectangle = 44 m²

Formula : -

Area of the rectangle = lb

lb = 44

x * 11/3 = 44

x = ( 44 * 3 ) / 11

x = 4 * 3

x = 12 m

Therefore,

the missing length = 12 m
