The number of the pages in the book if the first page will be numbered as 1 will be 1099 pages. And if the number of the pages is n then the function is shown below.
What is Algebra?Algebra is the study of mathematical symbols, and the rule is the manipulation of those symbols.
In numbering pages of a book, a printer used 3289 digits.
Then the number of the pages in the book if the first page will be numbered as 1.
One digit number = 1 - 9 = 9 digits
Two digit number = 10 - 99 = 2 x 90 = 180 digits
Three digit number = 100 - 999 = 3 x 900 = 2700 digits
Then the total number of the digit is used will be
→ 9 + 180 + 2700
→ 2889
The number of the remaining digits will be
→ 3289 - 2889
→ 400
Then the four-digit number will be
→ 400/4
→ 100
Then the total number of the pages will be
Total pages = 9 + 90 + 900 + 100
Total pages = 1099
If n pages are there, then the number of the digits are required will be
[tex]\left\{\begin{matrix}n, & 1\leq n\leq 9 \\9+(n-9)2, & 10\leq n\leq 99 \\189+(n-9)3, & 100\leq n\leq 999 \\. & . \\. & . \\\end{matrix}\right.[/tex]

The circumference of a circular garden is approximately 20 feet. What is the approximate area inside the circular garden?
Answer:
31.85 square feet
Step-by-step explanation:
Finding the radius :
C = 2πr20 = 2πrr = 20/2πr = 10/πSubstituting in the area formula :
A = πr²A = π × 10/π x 10/πA = 100/πA = 100/3.14A = 31.85 square feetSo
2πr=20πr=10r=10/πNow

Answer: x + 4
Step-by-step explanation:
If it is asking us for (f - g)x, then we will subtract the function g from function f. Why? The x distributes creating f(x) - g(x), so we use this to solve.
Given:
g(x) = 2x - 2
f(x) = 3x + 2
Set up:
f(x) - g(x)
(3x + 2) - (2x - 2)
Distribute the negatie:
3x + 2 - 2x + 2
Reorder to combine like terms:
3x - 2x + 2 + 2
Combine like terms:
x + 4
(f - g)(x) = x + 4

(2x 3)(x 1) (2x−3)(x−1) (3x 2)(x 1) (3x−2)(x−1)
The algebra tile configuration that represents the factors of 2x² + 5x + 3 must have a product of (2x + 3) and (x + 1)
How to model the factor?The expression is given as:
2x² + 5x + 3
Expand the expression
2x² + 5x + 3 = 2x² + 2x + 3x + 3
Factorize the expression
2x² + 5x + 3 = 2x(x + 1) + 3(x + 1)
Factor out x + 1
2x² + 5x + 3 = (2x + 3)(x + 1)

Not only would I like the value of x, but also I wonder how I’d go about solving this problem?
Answer:
x = 58
Step-by-step explanation:
This question can be solved by using the exterior angle property, which states that the exterior angle of a triangle = the sum of the two opposite interior angles.
62 lies on a line, so the exterior angle is 180 - 62, or 118 degrees.
Using the EAP, we can conclude the following:
(x + 2) + (x) = 118
2x + 2 = 118
2x = 116
x = 58
Hope this helps
Answer:
X=58
Step-by-step explanation:
1.) 62+2+2x=180
2) 64+2x=180 (add 62 and 2)
3) 2x=116 (subtract 64 from 180)
4)x=58 (divide 116 by 2 =58

Answer:
(4)^5
Step-by-step explanation:
When multiplying expressions with exponents you add the exponents together so in this equation you would get -4^11/-4^6. However since both exponent have the same base (-4) you can simplify it farther. When dividing expression with exponents you subtract the exponents. So, here, you would get 4^5.

Melody need 155 bags of 140 cu. inches to fill the vegetable garden.
What is Volume of Cuboid?The volume of the cuboid is the measure of the space occupied within a cuboid. The cuboid is a three-dimensional shape that has length, breadth, and height.
Here, Length of vegetable garden = 48 inch
breadth of garden = 30 inches
height of garden = 15 inches
Volume of garden = Length X width X height
= 48 X 30 X 15
= 21600 cu. inches
Volume of each bag = 140 cu. inches
Number of Bags required = Volume of garden/Volume of each bag
= 21600 / 140
≈ 155
Thus, Melody need 155 bags of 140 cu. inches to fill the vegetable garden.

A and B are independent events. If P(A) = 0.50 and P(A and B) = 0.20, find P(B).
The independent events are illustrations of probability, and the value of P(B) is 0.40
How to determine the value of P(B)?The given parameters are:
P(A) = 0.50
P(A and B) = 0.20
Two events A and B are independent, if
P(A and B) = P(A) * P(B)
So, we have:
0.50 * P(B) = 0.20
Divide both sides by 0.50
P(B) = 0.40
Hence, the value of P(B) is 0.40

If they sell their CDs for $10 each, how many must they sell before they make a profit?

6x > 1500
x > 250
Since x cannot equal 250, they must sell 251 CD's before they can make a profit.
