what is real numbers? explain briefly..
Answer:
a quantity that can be expressed as an infinite decimal expansion is real number.This includes all integers and all rational and irrational numbers.It can be either positive or negative.it can be either rational and irrational but not both It is demoted by R .Then numbers which are not both rational and irrational are not real numbers.

Diego has 1/4 of a book left to read. There is 6 chapters left each chapter is the same length. What fraction of the book is each chapter
Answer:
Fraction of the book is each chapter = 1 / 24
Step-by-step explanation:
Given:
Fraction of book left to read = 1/4 book
Number of chapter left to read = 6 chapter
Find;
Fraction of the book is each chapter
Computation:
Total number of chapter in book = Number of chapter left to read / Fraction of book left to read
Total number of chapter in book = 4 x 6
Total number of chapter in book = 24 chapters
Fraction of the book is each chapter = Number of book / Total number of chapter in book
Fraction of the book is each chapter = 1 / 24
slope for (0,0) and (3,30)
Slope is the change in y over the change in x:
Slope = (30-0)/(3-0)
Slope = 30/3
Slope = 10
Answer:
The formula for slope is (y2-y1)/(x2-x1)
Hence, the answer will be:
(30-0)/(3-0)
=30/3
=10
What is the coefficient in the expression shown?
Answer:
In mathematics, a coefficient is a multiplicative factor in some term of a polynomial, a series, or any expression; it is usually a number, but may be any expression.
Step-by-step explanation:
y = x2 + 5x - 14 in factored form need answe asap please
Answer:
y = ( x-2)(x+7)
Step-by-step explanation:
y = x^2 + 5x - 14
What 2 numbers multiply to -14 and add to 5
-2 * 7 = -14
-2+7 = 5
y = ( x-2)(x+7)
The numerator of a rational number is less thanits denominator by 7. If the new number becomes [tex]\frac{3}{2}[/tex] when the numerator is tripled and the denominator is increased by 13, find the original number.
Answer:
Step-by-step explanation:
If the numerator is 7 less than its denominator, than the original number in terms of x is
[tex]\frac{x-7}{x}[/tex]. If we triple the numerator, the expression to do this is 3(x - 7); if we increase the denominator, the expression to do this is x + 13. Putting that together along with the fact that after we do this manipulation the new number is 3/2:
[tex]\frac{3(x-7)}{x+13}=\frac{3}{2}[/tex] and distribute:
[tex]\frac{3x-21}{x+13}=\frac{3}{2}[/tex] and cross multiply to get:
2(3x - 21) = 3(x + 13) and
6x - 42 = 3x + 39 and
3x = 81 so
x = 27. Subbing 27 for x into the original number:
[tex]\frac{27-7}{27}=\frac{20}{27}[/tex]

Sumaya's Smoothie Store is planning to sell an extra-large size. The extra-large size will have three times the volume of the small size. It will cost twice as much as the small size. Which coordinate pair represents the volume and cost of the extra-large size?
Answer:
The answer is below
Step-by-step explanation:
Sumaya’s Smoothie Store is planning to sell an extra-large size. The extra-large size will have three times the volume of the small size (the small size is (8,4) ). It will cost twice as much as the small size.
Which coordinate pair represents the volume and cost of the extra-large size?
Solution:
The coordinate plane is a plane that can be used to represent the position of a point. The plane consist of x axes and y axes. The position of a point is referenced from the origin.
The small size of a pizza is represented by the coordinate pair (8, 4) ⇒ (volume, cost)
Since the volume of the extra-large size will have three times the volume of the small size, hence:
Volume of extra-large size = 8 * 3 = 24
The cost of extra large is twice as much as the small size, hence:
Cost of extra large = 4 * 2 = 8
Therefore the coordinate pair that represents the volume and cost of the extra-large size is:
(24, 8)
For #4 - 5, the two polygons are similar. Find the
values of x and y.
60°
18
12
22
x + 4
4.
Answer:
x = 10.7
y = 120°
Step-by-step explanation:
If two polygons are similar, their corresponding angles would be the same, while the ratio of their corresponding sides will be equal.
Therefore, the angles of the two polygons given are equal, while the ratio of their corresponding side length is equal.
Thus:
✔️Find x:
22/(x + 4) = 18/12
22/(x + 4) = 3/2
Cross multiply
(x + 4)3 = 2*22
3x + 12 = 44
Subtract 12 from each side
3x = 44 - 12
3x = 32
x = 32/3
x = 10.7
✔️Find y:
y + 60° = 180° (adjacent angles are supplementary)
y = 180 - 60
y = 120°

Answer:
2054.43$ = 2054$
Step-by-step explanation:
Here, by analyzing the question we get;
Principal= 1000$
Time (In years) = 12
Rate (Annual) = 6%
Now;
First convert R into decimal= 0.06 rate per year
Now solving the equation for A:
A=Pe^(rt)
=1000(2.71828)^(0.06*12)
=$2054.43

Answer:
The rules for standard form are
Small numbers can also be written in standard form. However, instead of the index being positive (in the above example, the index was 3), it will be negative. The rules when writing a number in standard form is that first you write down a number between 1 and 10, then you write × 10(to the power of a number)
