I'm not sure about part B, but part A will have the answer "if Ron eats lunch today, then he will drink a glass of milk" (without quotes of course)

The idea is that we have these arguments in symbolic form
P = Ron eats lunch today
Q = Ron eats a sandwich
R = Ron will drink a glass of milk

The format is
"If P then Q" ----> "if Q then R" so therefore "If P then R"

We see that P leads to Q, then Q leads to R. So overall P leads to R. We connect them as a chain of sorts. We can skip over Q since we know the first point will lead to the last. Think of it as a shortcut of sorts.

Which statement is not always true?

A. True. Summing any rational number with an irrational number leads to an irrational result. The proof is a bit lengthy so I'm leaving it out.

B. True. Adding p/q with r/s leads to (ps+qr)/(qs) which is rational. Keep in mind that q and s cannot be zero.

C. False. One counter example is sqrt(3)*sqrt(12) = sqrt(3*12) = sqrt(36) = 6. This shows the product of two irrational numbers, in this case sqrt(3) and sqrt(12), multiplying to get a rational result 6 = 6/1.

D. True. Multiplying p/q and r/s leads to (p*r)/(q*s) which is rational. Keep in mind that q and s cannot be zero.

The final answer is choice C

Evaluate sin(Tan^-10)

Musya8 [376]

$\tan x=0$ for $x=n\pi$ , where $n$ is any integer. The inverse tangent function returns numbers between $-\dfrac\pi2$ and $\dfrac\pi2$ . The only multiple of $\pi$ in this range is 0, so $\tan^{-1}0=0$ .

Then

$\sin\left(\tan^{-1}0\right)=\sin0=\boxed0$

Simplify 36x^4 42x^7

Alja [10]

The first step to simplify this equation is to multiply the numbers
1512 $x^{4}$ × $x^{7}$
next,, youll multiply the terms with the same base by adding their exponents
1512 $x^{4+7}$
finally,, youll add the numbers together
1512 $x^{11}$
since you cant simplify any further,, the correct answer to your question is 1512 $x^{11}$
let me know if you have any further questions

Answer:

8 pencils per student.

Step-by-step explanation:

Since there are 4000 pencils and 500 students we can do 500 divided by 4000 to get our rate, 8 pencils for every student.
