<span>x2 = 81 if and only if x = 9.
</span><span>this statement means 

</span>x2 = 81 implies x = 9, and x = 9 implies x²=81
 so the converse of <span>If x = 9, then x2 = 81 is </span><span>If x2 = 81, then x = 9</span>

The converse statement  interchange the hypothesis and the conclusion.

The converse of x=9 then x^{2} =81.  is x^{2} = 81 then x=9. is true.

A biconditional statement is defined to be true whenever both parts have the same truth value . combining  the statements as a biconditional we have

If x^{2}. = 81, then x = 9.  

x = 9 if and only if x^{2} . = 81

Option D is the right answer.

denis23 [38]
So I added all of the numbers of tourists together, I got 30 tourists. Then I saw that the number of tourists that visisted the museum but not the zoo was 5. I divided 5 by 30 and got that there was a 16% chance that a randomly selected tourist would of visited the museum but NOT the zoo. 
Hope this helps!

Gia can run 4 miles in 32 minutes. At that rate, how many miles can she run in 40 minutes ​
Nitella [24]

Answer:

5

Step-by-step explanation:

For these types of problems, we can use cross - multiplication.

4/32 = x/40

Notice that since 40 and 32 are both measured in minutes, we put them on the same line.

Now, like the name suggests, we cross multiply the equation, by doing 4 * 40 = 32 * x. Now, we are left with 160 = 32x. After solving this, we get the answer 5.
