Explanation
A right triangle is a triangle that has one angle measuring 90 degrees. Therefore, the correct answer is 90, as this is the number of degrees in a right triangle.

Explanation
The given expression follows the order of operations, known as PEMDAS (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction). According to this rule, we first solve the expression inside the parentheses, which is 2x15, resulting in 30. Then, we multiply 2 by 30, giving us 60. Therefore, the correct answer is 60, not 34.

Explanation
The given equation states that a certain value is equal to pi. Among the options provided, only 3.14 is equal to pi.

Explanation
The square root of a number is a value that, when multiplied by itself, gives the original number. In this case, the square root of 49 is 7 because 7 multiplied by itself equals 49. Therefore, the correct answer is 7.

Explanation
The correct answer is 1,400 because when you add 700 and 700 together, you get a total of 1,400.

Explanation
The answer "1 out of 2" is the correct choice because it represents the smallest fraction among the given options. The other fractions, "2 out of 3," "7 out of 9," and "6 out of 12," are all larger fractions. To reduce a fraction, the numerator and denominator should be divided by their greatest common divisor. In this case, 1 is already the smallest possible numerator, and 2 is the smallest possible denominator. Therefore, "1 out of 2" cannot be further reduced.

Explanation
The number equivalent to (34/32) is 1.0625. However, none of the given options match this value. Therefore, the correct answer cannot be determined from the options provided.
