Answer :
the equation should be: how many people * daily trash * 365 days in a year = kilograms of trash was thrown away in the United States in 2013
so enter your givens and it's now (we'll use
4.5 × 10–1 kg * 3.2 × 106 * 365=14.4x10^5x365
5256x10^5
525600000
so enter your givens and it's now (we'll use
4.5 × 10–1 kg * 3.2 × 106 * 365=14.4x10^5x365
5256x10^5
525600000
The correct answer is:
52,596,000
Explanation:
We multiply 4.5×10⁻¹ × 3.2×10⁶. To do this, we can use the commutative property and switch the factors around:
4.5(3.2)(10⁻¹)(10⁶)
Using our powers of exponents, we know that multiplying powers of the same base means we add exponents; this gives us
4.5(3.2)(10⁵)
This gives us
14.4(10⁵) = 144,000.
This is the amount thrown away per day. There are 365.25 days per year; this gives us
144000(365.25) = 52,596,000
