If p and q are non-zero rational numbers, and s and t are irrational numbers, select all of the statements that are always false.answer choices are
The product pq is irrational.

The product pt is irrational.

The quotient pq is irrational.

The product st is irrational.

The quotient st is rational.

Answers

The false statements are:

The product pq is irrational.

The quotient pq is irrational.

The quotient st is rational.

A rational number is a number can be expressed as a fraction of two whole numbers. While, an irrational number is a number that cannot be expressed as the fraction of two whole numbers.

Examples of rational numbers are: 6, 2,3

Examples of irrational numbers are: √2, √3

Let p and q be represented with 2 and 6 respectively.

The product of 2 and 3 = 2 x 6 = . The number is a rational number

Let p and t be represented with 2 and √2 respectively.

The product of 2 and √2 = 2 x√2 = 2√2. The product is irrational

The quotient of pq = 6 /2 = 3.

The quotient is rational.

Let s and t be represented with √2, √3. The product is √2 x √3 = √6. The product is irrational.

The quotient of s and t = √2 /√3.

The number is irrational.

Answer:

The false choices are A, C, and E

Step-by-step explanation:

Let's make an example:

p=1

q=2

s=sqrt(3)

t=sqrt(6)

Since pq=1*2=2, the answer is rational and A is false.

Since pt=1*sqrt(6)=sqrt(6), the answer is irrational and B is true.

Since p/q=1/2=0.5, the answer is rational and C is false.

Since st=sqrt(3)*sqrt(6)=sqrt(18), the answer is irrational and D is true.

Since s/t=sqrt(3)/sqrt(6)=sqrt(1/2), the answer is irrational and E is false.

What is the missing coefficient of the x-term of the product (-x-5)2 after it has been simplified

Answers

Answer:

we have

(-x -5) to the power of 2

we know that

(-x -5) to the power of 2 = (-x -5) x (-x -5)

To multiply two binomial I can use the FOIL method

(-x -5) x (-x -5) = (-x) x (-x) + (-x) x (-5) + (-5) x (-x) + (-5) x (-5)

= X to the power of 2 + 5x +5x + 25

= x to the power of 2 +10x +25

therefore

the answer is

the missing coefficient of the x-term is 10

90 students were surveyed about their favorite subject in school between Math and Social Studies. How many students chose only math as their favorite subject? (3 points)32 social studies
20 chose both

Answers

Answer: 38 students

Step-by-step explanation:

There are only 90 students. You subtract 90 minus the 32 that said social studies was there favorite. So now you have 58 then minus the people who said both which was 20. Your left with 38. So 38 students said just math as there favorite subject.
