What is decimal number ?When expressing a whole number and a fraction together, decimals are utilized. Here, we shall use a "." (also known as a decimal point) to demarcate the full number from the fraction. Say, for illustration, that you intend to bring a cone of ice cream. You are informed by the vendor that ice cream costs $2 and 50 cents. Now, if you wanted to sum up this cost in a single number, you would say that an ice cream cone costs $2.50.

C. integer
D. whole
E. natural
F. not rational
Answers
The number √2 is an irrational number, thus, the correct options are B: irrational and F: not rational
To wich sets the number belongs?Remember what each sets are.
Natural or whole numbers are all the numbers that can be get by adding ones to one {1, 2, 3, 4, ...}
Integers are like the above ones, but also includes the zero and negative numbers.
Rationals are the ones that can be written as a quotient between two integers, and irrationals are these ones that can't be written like that.
Finally, real numbers are all the numbers.
In this case we have the square root of a prime number, √2, this is always a irrational number.
Then option B is correct.
Trivially, option F (not rational) is also true, because if the number is irrational, then it is not rational.
Then the correct options are B and F.

Which numbers are solutions of x^2 + 20 = 9x + 2?
Answers
Answer:
x = 6 or x = 3
Step-by-step explanation:
Solve for x over the real numbers:
x^2 + 20 = 9 x + 2
Subtract 9 x + 2 from both sides:
x^2 - 9 x + 18 = 0
The left-hand side factors into a product with two terms:
(x - 6) (x - 3) = 0
Split into two equations:
x - 6 = 0 or x - 3 = 0

The value of expression c − a + b d on simplification is (-10101.2).
As per question we need to solve the given equation i.e., c − a + b d
And we are provided with the values of a, b , c and d.
Here we have ,
a=78,
b=−716
c=0.8
and d=14
The given equation is,
c − a + b d
Now we need to substitute the value of a, b, c and d. On substituting the value of a, b, c and d , we get
(0.8) - 78 + (-716) (14)

Procedure:
• Finding the angles
We know that C = 90° as the image shows the symbols. Also, we know that the sum of the interior angles of a triangle are 180°. Then, to get A we have to do the following:
[tex]A+B+C=180[/tex]Isolating for A:

Finally, using the Pythagorean Theorem, we can calculate c:

Answers
The probability of Ryan choosing a flavor that he does not like is 3/10.
What is probability?Simply put, the probability is the likelihood that something will occur. When we don't know how an event will turn out, we can discuss the likelihood or likelihood of various outcomes. Statistics is the study of events that follow a probability distribution. The probability is calculated by dividing the total number of possible outcomes by the number of possible ways the event could occur. Probability and odds are two distinct ideas. Odds are calculated by dividing the likelihood of an event by the likelihood that it won't.So, the formula for probability:
P = favourable events/Total eventsFavorable events: (Picking flavor that Ryan does not like) = 10 + 8Total events: (sum of all the jelly) = 60Now, insert the values in the probability formula as follows:
P = favourable events/Total eventsP = 18/60 ⇒ 9/30 ⇒ 3/10Therefore, the probability of Ryan choosing a flavor that he does not like is 3/10.

Since one of the endpoints is BX and the endpoint is XT and the midpoint is X.
The distance between B and X is 3 units.
Since X is the midpoint, the distance between X and T is equal to 3 units.

Write the equation of a line that is parallel to the line 2x - 3y = 5 and passes through the point (3, -1)
Answers
Answer:
The equation of the line is 2x - 3y = 9
Step-by-step explanation:
Given:
Write the equation of a line that is parallel to the line 2x - 3y = 5 and passes through the point (3, -1)
Solve:
- The line is parallel to the line 2x - 3y = 5
⇒ the slope of the line = the slope of the line 2x - 3y = 5
- Rearrange the terms of the equation to be in the form
⇒ y = mx + c to find the slope of it
2x - 3y = 5 → subtract 2x from both sides
-3y = 5 - 2x ⇒ divide two sides by -3
y = 5/-3 - 2x/-3 ⇒ y = 2/3 x - 5/3
The slope of the line is 2/3
Given that: The line passes through point (3, -1)
Lets use the rule to find the equation of the line:
y - (-1)/x - 3 = 2/3
y + 1/x - 3 = 2/3 ⇒ by using cross multiplication
3(y + 1) = 2(x - 3) ⇒ open the brackets
3y + 3 = 2x -6 ⇒ put x and y on one side
2x - 3y = 3 + 6
2x - 3y = 9
The equation of the line is 2x - 3y = 9

group 1 bought 9 tickets and received a 120 discount, group 2 bougt 3 tickets and recived a 30 dollar discount both groups spentthe total amount of money on tickets
the price of each ticket was the same
what was the cost of each ticket?
Answers
The cost of each ticket bought by each of the group is $15.
What is the cost of each ticket?The linear equation that represents the total cost spent by group 1 on the tickets is:
Amount spent = total amount spent on the tickets - discount
9x - 120
The linear equation that represents the total cost spent by group 2 on the tickets is:
3x - 30
Where:
x = is the cost of the tickets
If both groups spend the same amount, the above two linear equations would be equal to each other
3x - 30 = 9x - 120
In order to determine the value of x, take the following steps:
Combine similar terms together: 120 - 30 = 9x - 3x
Add similar terms: 90 = 6x
Divide both sides by 6
