Answer:

This is 27% decrease.

Step-by-step explanation:

The amount of rainwater collected last year was 15.6 L, and this year it was 11.4 L, this means 15.6 L-11.4 L= 4.2 L less water was collected this year than last year.

This 4.2 L is

\frac{4.2L}{15.4L}*100

percent of the amount of water collected last year. Evaluating this we get:

\frac{4.2L}{15.4L}*100=0.269*100=26.9%

Rounding to the nearest percent this is 27%.

Thus, the percent decrease in the amount of rainwater collected is 27%.

Write 337,060 in expanded form using exponents
Agata [3.3K]

1. expand using place value.

337,060 = 300,000 + 30,000 + 7,000 + 000 + 60 + 0


Next, we will use exponents:

300,000 = 3 * 10^5

30,000 = 3 * 10^4

7,000 = 7 * 10^3

000 = 0 * 10^2

60 = 6 * 10

0 = 0 * 10^0


then after combing these exponents, we can write the number as:

337,060 = 3 * 10^5 + 3 * 10^4 + 7 * 10^3 + 0 * 10^2 + 6 * 10 + 0 * 10^0


Finally, removing the meaningless zeroes, we would end up with:

337,060 = 3 * 10^5 + 3 * 10^4 + 7 * 10^3 + 6 * 10
