Simplify: log base 3 (1/3) ...?

yarga [219]

The answer is 1.

$log_3( \frac{1}{3} )$
_____
Since $log_y(x) = \frac{log_{10}(x)}{log_{10}(y)}$ , then: $log_3( \frac{1}{3} )= \frac{log_{10} ( \frac{1}{3}) }{log_{10}(3)}$
_____
Since $\frac{1}{x} = x^{-1}$ , then: $\frac{log_{10} ( \frac{1}{3}) }{log_{10}(3)} = \frac{log_{10}(3^{-1} )}{log_{10}(3)}$
_____
Since $log x^{a} =a*logx$ , then: $\frac{log_{10}(3^{-1} )}{log_{10}(3)}= \frac{-1*log_{10}(3)}{log_{10}(3)}$

From here: $\frac{-1*log_{10}(3)}{log_{10}(3)}=-1*\frac{log_{10}(3)}{log_{10}(3)}=-1*1 = -1$

If 36 is 90% of a value, what is that value?

laila [671]

You know 36 is 90% of a value, so it will equal 90/100.
Multiply 90/100 types x (value). Easiest way is to simplify 90/100 = 9/10.
x = 36 / 9/10
x = 360 / 9
x = 40
Therefore, the value would be 40.

A plumber has been working at 4 customer sites. He has completed 1/4, 50%, 12.5%, 3/4 and of his work at the sites. Which list s

yanalaym [24]

Answer:

2. 3/4, 50%, 1/4, 12.5%

Step-by-step explanation:

Work completed at the 4 sites = 1/4, 50%, 12.5%, 3/4

1/4 = 0.25

50%

= 50/100

= 0.5

12.5%

= 12.5/100

= 0.125

3/4

= 0.75

in order from greatest to least?

3/4, 50%, 1/4, 12.5%

1. 12.5%, 1/4, 50%, 3/4

2. 3/4, 50%, 1/4, 12.5%

3. 3/4, 12.5%, 1/4, 50%

4. 1/4, 50%, 3/4, 12.5%
