To round a number, you look to the next place to the right of what you want to round to... for example, if you want to round to the nearest hundredth, you look to the thousandths place to see whether the hundredths place rounds up or down.
0.04 is already at the hundredths place so the thousandths place is zero... the answer to the nearest hundredth is 0.04.
For 0.2%, you have to convert the percentage to a decimal by dividing by 100 (move the decimal 2 places to the left).
0.2% = 0.002
So now to round to the nearest hundredth, we look to the thousandths place. The thousandths place has a 2 in it so the hundredths place rounds down. 0.2% total he nearest hundredth is 0.
70 ft because 7 is bigger than 5 and 7x10=70
The answer to this question is 4y+4
<em>Hi!</em>
<em></em>
<em>These can be set up as systems of equations.</em>
<em> </em>
<em>Let b = the number of birds, and let d = the number of dogs.</em>
<em> </em>
<em>b + d = 21</em>
<em> </em>
<em>2b + 4d = 76 (this is because birds have 2 legs and dogs have 4 legs.)</em>
<em> </em>
<em>You can solve this using either elimination or substitution.</em>

<em>Consider marking brainliest.</em>
Lets say your numbers are these...
10,20,30,40,50,60,70,80,90 and 100
you would add those to get 650
Now how many numbers did you add?
You added 10
so now divided
650 by 10
you get 65
that is the mean of those numbers!
