a piece of paper has a mass of 4.4 grams. a feather has a mass of 8.0x10^-3 gram. the mass of the piece of paper is how many times greater then the mass of the feather
To find out how many times greater the mass of the paper is compared to the mass of the feather, we need to divide the mass of the paper by the mass of the feather:
4.4 grams / 8.0x10^-3 gram = 550
Therefore, the mass of the piece of paper is 550 times greater than the mass of the feather.
-11 2/3 x (-4 1/5)
First, we need to convert the mixed numbers to improper fractions:
-11 2/3 = -35/3
-4 1/5 = -21/5
Now, we can multiply the fractions:
-35/3 x -21/5 = (35 x 21)/(3 x 5) = 735/15
We can simplify this fraction by dividing the numerator and denominator by their greatest common factor, which is 15:
735/15 = 49
Therefore, -11 2/3 x -4 1/5 = 49.
To find the number of times the mass of the piece of paper is greater than the mass of the feather, we simply need to divide the mass of the paper by the mass of the feather.
Mass of paper = 4.4 grams
Mass of feather = 8.0 x 10^-3 grams
To divide these two values, we can use the formula:
Number of times = Mass of paper / Mass of feather
Substituting the values:
Number of times = 4.4 / 8.0 x 10^-3
Now, let's simplify this expression:
First, let's convert the exponent form (scientific notation) to decimal form for easier calculation. The given value 8.0 x 10^-3 can be written as 0.008.
Number of times = 4.4 / 0.008
Dividing 4.4 by 0.008 gives us:
Number of times = 550
Therefore, the mass of the piece of paper is 550 times greater than the mass of the feather.
