Answer:
10<em>m</em>
Step-by-step explanation:
Your teacher probably told you the necessary fundamentals of monomials. So, I'll just teach you the things needed for this particular question.
10<em>m</em>^3/(10<em>m</em>)(<em>m</em>)
First, in the denominator, since that <em>m</em> are being multiplied and they are the same <em>terms, </em>their exponents add:
10<em>m</em> * <em>m</em>
10<em>m</em>^1 * <em>m</em>^1
1 + 1 = 2
10<em>m</em>^2
Then, since that <em>m </em>are now being divided, their exponents subtract:
10<em>m</em>^3 / 10<em>m</em>^2
3 - 2 = 1
10<em>m</em>^1
10<em>m</em>
Answer:
12 square cm correct to 2 significant figures
Step-by-step explanation:
Area of a Rectangle = L X B = 2.1 X 5.6 = 11.76 square cm
To round your result to 2 significant figure, we start counting from the left from the first non-zero digit.
The first two digits are 11 but because the number after is 7 (greater than 4), we round up to 12.
11.76 square cm = 12 square cm correct to 2 significant figures
To get the answer. you have to find the unit rate.
To find the unit rate, divide 2.50 by 5 which is 0.5 or 50 cents.
(You can check to see if you did this right by multiplying, so .5x5=2.5)
Then you multiply .5 by 7 which is 3.5, or $3.50.
