2 5/7 as a decimal. How do you figure out?

weqwewe [10]

2 5/7 as a decimal is approximately 2.70

We know that the ones place will be a two. That doesn’t change when you convert. Next you need to divide 100 by 7, which equals 14. Then you need to do 14 times 5, which equals 70. So, now you know the values after the decimal point (.70). Combine that with the whole number 2 to get 2.70.

Write the log4 11/x as the difference between two logarithms.

anzhelika [568]

ANSWER

$log_{4}( \frac{11}{x} ) = log_{4}( 11 ) - log_{4}( x)$

EXPLANATION

The given logarithmic expression is

$log_{4}( \frac{11}{x} )$

Recall the quotient law of logarithms:

$log_{a}( \frac{m}{n} ) = log_{a}( m ) - log_{a}( n)$

We apply this property to obtain;

$log_{4}( \frac{11}{x} ) = log_{4}( 11 ) - log_{4}( x)$

You now fill in the blank with 11 on the right hand side.

I can finish the problems in one chapter of my physics book in 8 hours. Suppose that the problems in each chapter take the same

Jet001 [13]

Well I suppose it depends on how long you have in a day but...

with 30 people you can have it done in about 8hrs

but with 20 people you can have it done in about 12 hours

so my best guess would be anywhere between 20-30 people
