However, the dosimeter is actually worn by the worker to determine the personal noise dose during the workshift or sampling period (Figure 21). Noise dosimetry is a form of personal sampling, averaging noise exposure over time and reporting results such as a TWA exposure or a percentage of the PEL.
False. To find the decimal point while multiplying, count the number of decimal places (to the right of the decimal) in the factors. Then use the total of decimal places and move to the product. Start on the left side, and move the decimal over one number place for each decimal place.
Example: 3.77*2.8=?
3.77
* 2.8
----------
10556
But this is without the decimal point.
3.77 has two decimal places, and 2.8 has one. Put them together and you get a total of three decimal places.
10556, then, should have three decimal places.
Your answer would be 10.556
I hope this wasn't too confusing.
Answer:
12.25 x < 12.35
Step-by-step explanation:
5 is the cut off when rounding.
If a number to the right is greater than or equal 5, you round up.
If it's less than 5, you drop the number.
So 12.25 would be rounded up to 12.3
12.34 would be rounded to 12.3
How do you get the 12.25?
Subtract .05 from 12.3
How do you get 12.35?
Add .05 to 12.3.
The number in the hundredths place needs to be less than 5 to round down. That's why you use less than symbol.
Sum of two sides of triangle always greater than third side, so third side (x) could be:
14 < x < 32
Elio is right in assuming the relationship between the height and the hours it burns is proportional.
Find the unit rate
14 ÷ 8 = 1.75 cm/h
Divide
21 ÷ 1.75 = 12
You can set this up as an algebraic equation to check the answer.
If the candle is 21 cm tall, it will burn for 12 hours.
Hope this helped you! :)
