How do I convert 82.1, 7.3, 9.3 in a fraction form

nalin [4]

Answer:

Step-by-step explanation:

82.1 = 82 1/10 (thats 82 and 1/10) or 821/10 (if you dont want a mixed number)

7.3 = 7 3/10 or 73/10

9.3 = 9 3/10 or 93/10

if there is 1 number to the right of the decimal, put that number over 10....not the whole number, just the number to the right of the decimal. Leave the number to the left of the decimal alone.

if there were 2 numbers to the right of the decimal, then put those two numbers over 100.

example :

3.43 = 3 43/100

2.76 = 2 76/100

if there were 3 numbers to the right of the decimal, put those 3 numbers over 1000

example :

2.347 = 2 347/1000

3.679 = 3 679/1000

you understand ?

Hey Gary :) Nice to see you around

For this question, we want to use logarithmic rules to write the expression as a single logarithm.
Using the rule $log_{b} ( M^{k} ) = k * log_{b} M$ , we can simplify
$3log_{b} q$ to $log_{b} ( q^{3} )$ . We can also simplify $6log_{b}(v)$ to $log_{b}( v^{6})$ .

So, we have $log_{b} ( q^{3} )$ + $log_{b}( v^{6})$ .

Another logarithmic rule is:
$log_{b}(M*N) = log_{b} M + log_{b} N
$

Using this rule, we can use the logs we have calculated and change them to:
$log_{b}( q^{3} v^{6})$

This matches answer choice A.

Hope this helps! Feel free to contact me with any questions.

Over [174]

In this question , the triangle is equilateral triangle , with radius equals to 8 cm and we have to find the length of apotherm, a .

Using sine ratio rule,

$sin C = \frac{ opposite}{hypotenuse}$
