a.-15***
b.3/5
c.square-root of 7
d.0.252525...

2.Which statement is false?(1 point)
a.Every integer is a real number
b.The number zero is a rational number
c.Every irrational number is a real number***
d.Every real number is a rational number

4.Which statement is true?(1 point)
a.All irrational numbers are also rational numbers.
b.Half of the irrational numbers are also rational numbers.
c.One-third of the irrational numbers are also rational numbers.
d.Irrational numbers cannot be classified as rational numbers
I think it's A or B.

5.Indicate whether the following statement is true or false:(1 point)
The number -3 is an integer and a rational number.
A. True
B. False

1.A

2.D
3.C
4.D
5.B
You'll get 100%

#2 is clearly d)

#4 is clearly d)

#5
-3 is an integer
-3 = -3/1 so I can write it as a fraction
What do you think?

Cool...Thanks

BRUH IS A LIAR THE LAST ANSWER IS B

1. To determine which of the options is an example of an integer, we need to understand what an integer is. An integer is a number that can be positive, negative, or zero, and does not have any fractional or decimal parts.

Let's examine the options:
a. -15 - This is a negative number without any decimal part, so it is an example of an integer.
b. 3/5 - This is a fraction, which means it has a decimal part, so it is not an example of an integer.
c. Square root of 7 - The square root of 7 is an irrational number and not an integer.
d. 0.252525... - This is a repeating decimal, which means it has a decimal part, so it is not an example of an integer.

Therefore, the correct answer is a. -15.

2. To identify the false statement, we need to evaluate each option.
a. Every integer is a real number - This statement is true since integers are a subset of real numbers.
b. The number zero is a rational number - This statement is true since zero can be expressed as a fraction (0/1), making it a rational number.
c. Every irrational number is a real number - This statement is true since all irrational numbers are real numbers.
d. Every real number is a rational number - This statement is false since there are real numbers that cannot be expressed as a fraction, such as irrational numbers.

Therefore, the false statement is c. Every irrational number is a real number.

4. To determine which statement is true, we need to consider the properties of irrational and rational numbers.
a. All irrational numbers are also rational numbers - This statement is false since irrational numbers cannot be expressed as a fraction.
b. Half of the irrational numbers are also rational numbers - This statement is false since irrational numbers are not rational.
c. One-third of the irrational numbers are also rational numbers - This statement is false since irrational numbers are not rational.
d. Irrational numbers cannot be classified as rational numbers - This statement is true since irrational numbers cannot be expressed as a fraction.

Therefore, the true statement is d. Irrational numbers cannot be classified as rational numbers.

5. To determine whether the statement is true or false, we need to consider the properties of integers and rational numbers.
The number -3 is an integer since it is a whole number that is also a negative number.
Rational numbers are numbers that can be expressed as a fraction or a ratio of two integers. The number -3 can be expressed as -3/1, which is a ratio of two integers.
Therefore, the statement is true.

Therefore, the correct answer is A. True.
