Which of the following illustrates the truth value of the given statements?
bekas [8.4K]

Answer:

T and F

Step-by-step explanation:

Hi! Maybe I am reading it wrong, but only 2 statements are given. The answer to these statements are true and false.

"A square root of 16 is 4."

4^{2} =16

4 squared, or 4 * 4 is equal to 16, and therefore this is true.

"The only square root of 9 is -3."

This is false. 9 has 2 square roots: 3 and -3.

3^{2} =9\\-3^{2} =9

3 * 3 = 9, and so does (-3) * (-3).

So we have T and F, which eliminates the second, third, and fourth choices, which means even without a last statement, A is your correct answer.

Hope I helped! :)

Beth rented a bike from Julia’s Bike. It cost $19.60 plus $6 per hour. If Beth rented the bike for two and half hours, how much
zimovet [89]

Answer:

She payed $34.60.

Step-by-step explanation:

It cost $19.60, just to rent the bike.

Then multiply $6 × 2 (hours) = 12

Now 6 ÷ 2 = 3 (half hour)

Add 12 + 3 = 15

Add everything together

19.60 + 15

You then get $34.60.
