Allushta [10]3 years ago

Answer:

2.727 \text{  to the nearest thousandth}

Step-by-step explanation:

I presume you were asked to evaluate Log_{3}20

To do this successfully, we apply one of the laws of logarithm which states that:

Log_{a}b=\dfrac{Log \:b}{Log\: a}

In a like manner,

Log_{3}20=\dfrac{Log \:20}{Log\: 3}

Evaluating this with your calculator

\dfrac{Log \:20}{Log\: 3} \approx 2.727 \text{  (to the nearest thousandth)}

How do you compare and contrast decimals, fractions, and percents
Alisiya [41]
You would have to make them all one form that is the same, for example if you wanted to find out if 80%, 0.75, 1/2 are the same you would have to change them into the same form. If you wanted to make them all decimals it would be 0.08, 0.75, 0.5, if you wanted to make them all percents it would be 80%, 75%, 50%, you wanted them all of be a fraction it would be 4/5, 3/4, and 1/2. I hope explained this well and this helped :)

Juan has a piano next month . last week he practiced for 8 hours in the morning and 7 hours in the afternoon. each practice sess
timofeeve [1]
First of all we will divide 8 by 2 to get the number of full practices in the morning, which is 4. Next divide 7 by 2 to get the number of practices in the afternoon. Although there is a remainder, that remainder is not a full practice session, so we only count the whole numbers which is 3. 
4 + 3 = 7 full practice sessions.

To start off take 10 degrees/96 cups
If you look at the pattern the degrees go up by 5 and the cups go down by 4

What is 2.318 repeating as a mixed number?
ioda
The idea being, we first, move the repeating part to the left of the decimal point, by simply multiplying it by a power of 10, in this case, we need to move 318, so we need then 1000, 3 decimals, 3 zeros.

and we'll make the expression a variable, so let's do so first,

\bf \boxed{x=2.318318\overline{318}}\\\\
-------------------------------\\\\
\begin{array}{llll}
1000\cdot x&=&2318.318\overline{318}\\
&&2316+2.318318\overline{318}\\
&&2316+x
\end{array}\implies 1000x=2316+x
\\\\\\
999x=2316\implies x=\cfrac{2316}{999}\implies x=\cfrac{772}{333}\implies x=2\frac{106}{333}
