    • Distance, distance, distance

    • Distance, time, time^2

    • Distance, distance/time, distance/time^2

    • Distance/time, distance/time^2, distance/time^3

    Correct Answer
    A. Distance, distance/time, distance/time^2
    Explanation
    The equation x = A + Bt + Ct^2 represents the position of an object as a function of time. The term A represents the initial position or displacement of the object, which has dimensions of distance. The term Bt represents the velocity of the object, as it is the product of a constant B and time, and therefore has dimensions of distance/time. Finally, the term Ct^2 represents the acceleration of the object, as it is the product of a constant C and time squared, and therefore has dimensions of distance/time^2. Therefore, the dimensions of A, B, and C are distance, distance/time, and distance/time^2 respectively.

    A rectangular garden measures 15 m long and 13.7 m wide. What is the length of a diagonal from one corner of the garden to the other?

    • 18 m

    • 19 m

    • 20 m

    • 4.1 * 10^2

    Correct Answer
    A. 20 m
    Explanation
    The length of the diagonal of a rectangle can be found using the Pythagorean theorem, which states that in a right triangle, the square of the hypotenuse (the longest side) is equal to the sum of the squares of the other two sides. In this case, the length and width of the rectangle form the two sides of the right triangle, and the diagonal is the hypotenuse. Therefore, the length of the diagonal can be found by calculating the square root of the sum of the squares of the length and width. In this case, the square root of (15^2 + 13.7^2) is approximately 20 m.

    1 angstrom = 10^(-10) m and 1 fermi = 10^(-15) m, what is the relationship between these units?

    • 1 angstrom = 10^(5) fermi

    • 1 angstrom = 10^(-5) fermi

    • 1 angstrom = 10^(-25) fermi

    • 1 angstrom = 10^25 fermi

    Correct Answer
    A. 1 angstrom = 10^(5) fermi
    Explanation
    The relationship between angstrom and fermi can be determined by comparing their magnitudes. Since 1 angstrom is equal to 10^(-10) m and 1 fermi is equal to 10^(-15) m, we can convert 1 angstrom to fermi by multiplying it by 10^(-15)/10^(-10), which simplifies to 10^(-5). Therefore, 1 angstrom is equal to 10^(-5) fermi.

    • 3.25 * 10^(-10) mm.

    • 3.25 * 10^(-9) mm.

    Correct Answer
    A. 3.25 * 10^(-10) mm.
    Explanation
    The given expression represents a conversion from centimeters to millimeters. To convert from centimeters to millimeters, we multiply by 10. Since 0.00325 cm is being multiplied by 10^(-8), we need to multiply 0.00325 by 10^(-8) and then convert the result to millimeters by multiplying by 10. This gives us 3.25 * 10^(-10) mm.

    Which one of the following is not equivalent to 2.50 miles? (1 mi = 1.609, km = 5280 ft, 1 ft = 12 in.)

    • 1.32 * 10^4 ft

    • 1.58 * 10^5 in.

    • 4.02 * 10^3 km

    • 4.40 * 10^3 yd

    Correct Answer
    A. 4.02 * 10^3 km
    Explanation
    To find the equivalent of 2.50 miles, we need to convert it to different units. 1 mile is equal to 5280 feet, so 2.50 miles is equal to 2.50 * 5280 = 13200 feet. 1 mile is also equal to 1.609 kilometers, so 2.50 miles is equal to 2.50 * 1.609 = 4.0225 kilometers. Therefore, the option that is not equivalent to 2.50 miles is 4.02 * 10^3 km, as it is slightly different from the actual value of 4.0225 kilometers.

    If you are 5'10'' tall, what is your height in meters? (1 in = 2.54 cm.)

    • 1.5 m

    • 1.6 m

    • 1.7 m

    • 1.8 m

    Correct Answer
    A. 1.8 m
    Explanation
    To convert height from feet and inches to meters, we first need to convert feet to inches by multiplying by 12. So, 5 feet becomes 60 inches. Then, we add the remaining inches, which is 10 inches, to get a total of 70 inches. To convert inches to centimeters, we multiply by 2.54. So, 70 inches is equal to 177.8 cm. Finally, to convert centimeters to meters, we divide by 100. Therefore, a height of 5'10" is equal to approximately 1.78 meters. Since the closest option is 1.8 meters, that is the correct answer.

  • 48. 

    If 1 inch = 2.54 cm, and 1 yd = 36 in., how many meters are in 7.00 yd?

    • 6.40 m

    • 36.3 m

    • 640 m

    • 1.78 * 10^3 m

    Correct Answer
    A. 6.40 m
    Explanation
    To convert yards to meters, we need to first convert yards to inches and then inches to centimeters, and finally centimeters to meters. Since 1 yard is equal to 36 inches, we can multiply 7 yards by 36 inches/yard to get the total inches. Next, we can convert the inches to centimeters by multiplying by the conversion factor of 2.54 cm/inch. Finally, to convert centimeters to meters, we divide by 100. By performing these calculations, we find that 7.00 yards is equal to 640 centimeters or 6.40 meters.

    • 100 ft

    • 600 ft

    • 1200 ft

    • 3600 ft

    Correct Answer
    A. 3600 ft
    Explanation
    The hot air balloon rises to an altitude of 600 fathoms. Since 1 fathom is equal to 6 feet, we can calculate the height in feet by multiplying the number of fathoms by 6. Therefore, 600 fathoms multiplied by 6 feet equals 3600 feet.
