Which of the following are rational numbers {7,-5,2/3,5.79,,√13,√-4}

Ilia_Sergeevich [38]

Answer:

7, -5, 2/3, 5.79

Step-by-step explanation:

rational numbers are numbers you can put in fraction form. $\sqrt{13}$ is not a perfect square, therefore you cannot put it in fraction form. $\sqrt{-4}$ is an imaginary number. Rational numbers are in the Real Numbers category, so it is not a rational number.

each course in college X is worth either two or three credits the members of the men’s swim team are taking a total of 47 course

omeli [17]

36 two credit courses and 11 three credit courses has been taken.

<u>SOLUTION: </u>

Given, each course in college X is worth either two or three credits. The members of the men’s swim team are taking a total of 47 courses that are worth a total of 105 credits .

We have to number of two credit courses and three credit courses are being taken .

Now, let the number of 2 credits courses be n, then number of 3 credits courses will be $47-n$ .

And, according to the given information, Total credits = 105

$\begin{array}{l}{\rightarrow \text { Credits for two credit courses }+\text { credits from three credits courses }=105} \\\\ {\rightarrow 2 \times \text { number of two credit courses }+3 \times \text { number of three lcredit courses }=105} \\\\ {\rightarrow 2 \times n+3 \times(47-n)=105} \\\\ {\rightarrow 2 n+141-3 n=105} \\\\ {\rightarrow 3 n-2 n=141-105} \\\\ {\rightarrow n=36}\end{array}$

So, two credits courses count is 36, the three credit courses count is $47-36 = 11$
