Which numbers are rational?
Answer:
1, 4, 5
Step-by-step explanation:
a rational number is defined as a number that can be written as a fraction. so, 4 and 5 are automatically checked off. 1 also simplifies to plus or minus 11, which is a whole number, meaning it is automatically rational. 2 is not rational because there is no set pattern in the decimal, so it can not be written as a fraction. 3 is the same thing, so it is irrational.

A gardener has ten plants (four tomato, two pepper, and four cucumber) to put in her garden. If she chooses the plants at random, what is the probability that the first one is a tomato plant, and the second one is a cucumber plant?
Answer:
8/45
Step-by-step explanation:
Given that:
Total Number of plants = 10
Number of tomato = 4
Number of pepper = 2
Number of cucumber = 4
If two plants are chosen at random:
Assume it is picked without replacement :
P(first is tomato plant) :
Recall : probability (p) = required outcome / Total possible outcomes
P(first is tomato plant) = 4 / 10 = 2/5
P(second is a cucumber plant) :
Number of plants = (10 - 1) =9 after first pick
P(second is a cucumber plant) = 4 / 9
Hence,
P(first tomato and second cucumber) = 2/5 * 4/9 (independent events)
2/5 * 4/9 = 8/45

Consider this expression.
-3x2- 24x - 36
What expression is equivalent to the given expression?
Answer:
-3 2 6
Step-by-step explanation:
Consider this expression.
-3x2- 24x - 36
What expression is equivalent to the given expression?
-3 (x + 2)(x+6)
Drop down answer is in bold
The equivalent expression will be : - 3 (x + 2) (x + 6)
We have the following expression -
[tex]-3x^{2}[/tex] - 24x - 36
We have to find out the equivalent expression of above expression.
Expand the following expression - (x + 2)(x + 4).Above expression can be expanded in the following way -
(x + 2)(x + 4) = x(x + 2) + 4(x + 4) = [tex]x^{2}[/tex] + 2x + 4x + 16 = [tex]x^{2}[/tex] + 2x + 16
According to question -
[tex]-3x^{2}[/tex] - 24x - 36
- 3 ([tex]x^{2}[/tex] + 8x + 12)
-3 ([tex]x^{2}[/tex] + 6x + 2x + 12)
-3 [x(x + 6) + 2(x + 6)]
-3(x + 2)(x + 6)
Hence, the equivalent expression will be : -3(x + 2)(x + 6)

What is Unit measurement?Number systems are systems in mathematics that are used to express numbers in various forms and are understood by computers. A number is a mathematical value used for counting and measuring objects, and for performing arithmetic calculations. Numbers have various categories like natural numbers, whole numbers, rational and irrational numbers, and so on. Similarly, there are various types of number systems that have different properties, like the binary number system, the octal number system, the decimal number system, and the hexadecimal number system.
A number system is a system representing numbers. It is also called the system of numeration and it defines a set of values to represent a quantity
Given:
height= 6 feet and 7 inches
Convert feet to meter
1 feet= 0.3048 meter
6 feet = 6* 0.3048
=1.8288 meter
Now, convert inch to meter
1 inch= 0.0254 meter
7 inch = 0.0254 * 7
=0.1778 meter
So,
6 feet and 7 inches= 1.8288 + 0.1778
= 2.0066 meter

Solve the following quadratic equation by factoring.
x^2 - 5x = 14
(Answers are in photo)
10 points!!!
Please explain how you got your answer.
Answer:
x = 7, -2
Step-by-step explanation:
Factor and set each factor equal to 0==========================================
Work Shown:
x^2 - 5x = 14
x^2 - 5x - 14 = 0
(x-7)(x+2) = 0 .... this step is further explained below
x-7 = 0 or x+2 = 0
x = 7 or x = -2
The order of the solutions does not matter.
-------------------------
To factor x^2-5x-14, we need to find two numbers that multiply to -14 and add to -5. This is done through trial and error. I recommend making a table to help organize everything. See the diagram below.
After a bit of guess work, you should find that -7 and 2 are the two values we're after
-7 + 2 = -5
-7 * 2 = -14
This is why x^2-5x-14 = (x-7)(x+2)
