Answer:

160,000

Step-by-step explanation:

120,000 + 0.2(120,000)=120,000+24,000=144,000

144,000 were both populations in 2015.

x-0.1x = 144,000

0.9x=144,000

x=160,000

The Population of City Y in 2010 was 160,000

Write 0.0059 in scientific notation.
polet [3.4K]
Hi!

When we write a number in scientific notation, we write it like this:
N × 10^{x}

N = a number between one and 10
x = negative if the decimal is moved to the right. positive if moved to the left.

Okay, so we need to move the decimal in the number <span>0.0059 to the right to make it between one and 10.
0.0059
00.059
000.59
0005.9
5.9

N = 5.9
5.9 </span>× 10^{-x}

Since we moved the decimal to the right 3 times,
x = -3

5.9 × 10^{-3}
^ the answer

Hope this helps! :)
