     The human population on earth currently is approximately 7,125,000,000 people. Using scientific notation with the correct number of significant figures, this is  ________________________________ people 

    Correct Answer
    A.
    Explanation
    note only four significant figures since there is no decimal place. And note that this is about 7 billion people, not 7 trillion To convert to scientific notation make your number between 1 and 10 by drawing a line, then count the placeholders to the decimal point: 7|125 000 000. =

    If I have 12 g of grass and it takes up 30 cubic centimeters, what is the density of the grass?

    • 0.4 g/cubic centimeter

    • 2.5 g/cubic centimeter

    • 360 g/cubic centimeter

    • The information provided is not sufficient to draw a conclusion

    Correct Answer
    A. 0.4 g/cubic centimeter
    Explanation
    The density of a substance is calculated by dividing its mass by its volume. In this question, we are given that the mass of the grass is 12 g and it takes up 30 cubic centimeters of space. To find the density, we divide the mass (12 g) by the volume (30 cubic centimeters), which gives us a density of 0.4 g/cubic centimeter.

    • 3.86 x 10^-18 F/B

    • 3.86 x 10^-18 B

    Correct Answer
    A. 3.86 x 10^-18 F/B
    Explanation
    The given expression represents a value in scientific notation, where 3.86 is multiplied by 10 raised to the power of -18. This implies that the value is very small, as it is multiplied by a very small number (10^-18). The unit "F/B" indicates that the value represents a ratio or conversion factor between two quantities, with "F" representing the unit of the numerator and "B" representing the unit of the denominator. Therefore, the answer 3.86 x 10^-18 F/B suggests that the given expression represents a very small conversion factor or ratio between two quantities.

    • 180. grams per milliliter

    • Data Test Chapter 2 V2 10.22 - Quiz

    • Data Test Chapter 2 V2 10.22 - Quiz
    Correct Answer
    A.
    Explanation
    The density of a substance is calculated by dividing the mass of the substance by its volume. In this case, the mass of the helium is given as 4.03 milligrams and the volume is given as 22.40 milliliters. To convert milligrams to grams, we divide by 1000. So, the mass of the helium is 0.00403 grams. Therefore, the density of helium is 0.00403 grams divided by 22.40 milliliters, which equals 0.180 grams per milliliter.
