    One day, a person went to a horse racing area. Instead of counting the number of humans and horses, he counted 74 heads and 196 legs. How many humans and horses were there? - ProProfs

    One day, a person went to a horse racing area. Instead of counting the number of humans and horses, he counted 74 heads and 196 legs. How many humans and horses were there?

    • 37 humans and 98 horses

    • 24 horses and 50 humans

    • 31 horses and 74 humans

    • 24 humans and 50 horses

    Correct Answer
    A. 24 horses and 50 humans
    Explanation
    Let's use variables to represent the unknowns:
    Let 'h' be the number of humans
    Let 'x' be the number of horses
    We can set up two equations based on the given information:
    Equation 1 (heads): h + x = 74
    Equation 2 (legs): 2h + 4x = 196
    Now we can solve for 'h' and 'x'.
    Solve Equation 1 for 'h': h = 74 - x
    Substitute this value of 'h' into Equation 2: 2(74 - x) + 4x = 196
    Simplify and solve for 'x': 148 - 2x + 4x = 196 2x = 48 x = 24
    Substitute the value of 'x' back into the equation h = 74 - x: h = 74 - 24 h = 50
    Therefore, there were 50 humans and 24 horses.

    What's the only place in this world who's Fahrenheit and Celsius degrees can be equal? - ProProfs

    What's the only place in this world who's Fahrenheit and Celsius degrees can be equal?

    • Alaska at -50 degrees

    • Antarctica at -40 degrees

    • Hawaii at 100 degrees

    • Anywhere that exceeds freezing point

    Correct Answer
    A. Antarctica at -40 degrees
    Explanation
    Antarctica at -40 degrees is the only place in the world where Fahrenheit and Celsius degrees can be equal. This is because -40 degrees Fahrenheit is equal to -40 degrees Celsius. In all other options, the Fahrenheit and Celsius degrees are not equal.

    Y=log x If y=10, then what is x? - ProProfs

    Y=log x If y=10, then what is x?

    • 10

    • 1

    • 100

    • 10^2

    Correct Answer
    A. 10
    Explanation
    The equation y = log x represents a logarithmic function where the base is implicitly 10. To find the value of x when y = 10, we need to express the equation in exponential form.
    Since y = log₁₀x, then 10ʸ = x.
    Substituting y = 10, we get 10¹⁰ = x.

    What is the square root of 3 to the square root of 2 power times the square root of 3 to the negative square root of 2 power? - ProProfs

    What is the square root of 3 to the square root of 2 power times the square root of 3 to the negative square root of 2 power?

    • 100

    • 10

    • 1

    • 10^3

    Correct Answer
    A. 1
    Explanation
    The given expression can be simplified as follows: square root of 3 to the square root of 2 power is equal to 3^(sqrt(2)). Similarly, square root of 3 to the negative square root of 2 power is equal to 3^(-sqrt(2)). Therefore, the given expression becomes 3^(sqrt(2)) * 3^(-sqrt(2)), which is equal to 3^(sqrt(2) - sqrt(2)). Since the exponent is zero, any number raised to the power of zero is equal to 1. Hence, the answer is 1.

    Draw 2 supplementary angles. One angle is x-15 degrees and one is 2x degrees. What is the value of x in degrees? - ProProfs

    Draw 2 supplementary angles. One angle is x-15 degrees and one is 2x degrees. What is the value of x in degrees?

    • 65 degrees

    • 130 degrees

    • 100 degrees

    • 75 degrees

    Correct Answer
    A. 65 degrees
    Explanation
    Two angles are called supplementary if the sum of their measures is equal to 180 degrees. In this question, we are given two angles: one is x-15 degrees and the other is 2x degrees. To find the value of x, we need to set up an equation. The sum of the measures of the two angles is (x-15) + (2x) = 180. Simplifying this equation, we get 3x - 15 = 180. Adding 15 to both sides, we have 3x = 195. Dividing both sides by 3, we find x = 65 degrees. Therefore, the value of x is 65 degrees.

    What is the square root of 2 to the square root of 2 power to the square root of 2 power? - ProProfs

    What is the square root of 2 to the square root of 2 power to the square root of 2 power?

    • 2

    • 4

    • 8

    • 16

    Correct Answer
    A. 2
    Explanation
    The square root of 2 to the square root of 2 power can be simplified as 2^(√2). Then, raising 2 to the power of √2 is equivalent to taking the square root of 2. Therefore, the square root of 2 to the square root of 2 power is equal to 2.

    What is the square root of 2 to the negative 9 plus 3 power? - ProProfs

    What is the square root of 2 to the negative 9 plus 3 power?

    • 1/4

    • 1/8

    • 2/8

    • 1/2

    Correct Answer
    A. 1/8
    Explanation
    To simplify the expression, we need to evaluate the square root of 2 to the negative 9 plus 3 power. First, we simplify the exponent by adding -9 and 3, which gives us -6. Then, we take the square root of 2 to the power of -6. The square root of 2 is approximately 1.414, and raising it to the power of -6 gives us a very small number. Therefore, the answer is 1/8, as it is the only option that represents a small fraction.

    If 1/2x+1/2(1/2x+1/2(1/2x+1/2(1/2x+1/2...=y What does x equal? - ProProfs

    If 1/2x+1/2(1/2x+1/2(1/2x+1/2(1/2x+1/2...=y What does x equal?

    • 2/4

    • 1/2

    • 1/4

    • 1

    Correct Answer
    A. 1
    Explanation
    The given equation represents an infinite geometric series with a common ratio of 1/2. To find the value of y, we can use the formula for the sum of an infinite geometric series: S = a / (1 - r), where S is the sum, a is the first term, and r is the common ratio. In this case, a = 1/2x and r = 1/2. Plugging these values into the formula, we get y = (1/2x) / (1 - 1/2) = (1/2x) / (1/2) = (1/2x) * (2/1) = 1/x. Therefore, y = 1/x. Since the answer is given as 1, we can conclude that x must equal 1.
