4c + 5c = 92 - 2

9c = 90

c = 10

22 chairs were not used in the assembly.

The logarithm of a number to the base V2 is k. What is its logarithm to the base 2v2 ?

Answer:

$log_{2\sqrt 2} X = \frac{1}{3}k$

Step-by-step explanation:

Given

Let the number be X

From the first statement, we have:

$log_{\sqrt 2} X = k$

Required

Find $log_{2\sqrt 2} X$

$log_{\sqrt 2} X = k$

using the following law of logarithm

$log_ab = n, b=a^n$

So:

$log_{\sqrt 2} X = k$

$X = \sqrt{2}^k$

Substitute: $X = \sqrt{2}^k$ in $log_{2\sqrt 2} X$

$log_{2\sqrt 2} X = log_{2\sqrt 2} ( \sqrt{2}^k)$

$log_{2\sqrt 2} X = klog_{2\sqrt 2} \sqrt{2}$

Apply the following law:

$log_ab = \frac{log\ b}{log\ a}$

$log_{2\sqrt 2} X = k\frac{log\ \sqrt 2}{log\ {2\sqrt 2}}$

Express the square roots as power

$log_{2\sqrt 2} X = k\frac{log\ 2^\frac{1}{2}}{log\ {2 * 2^\frac{1}{2}}}$

$log_{2\sqrt 2} X = k\frac{log\ 2^\frac{1}{2}}{log\ {2^\frac{3}{2}}}$

using the following law of logarithm

$log_ab = n, b=a^n$

$log_{2\sqrt 2} X = k\frac{\frac{1}{2}log\ 2}{\frac{3}{2}log\ 2}}$

$log_{2\sqrt 2} X = k\frac{\frac{1}{2}}{\frac{3}{2}}}$

Rewrite as:

$log_{2\sqrt 2} X = k * \frac{1}{2} \div\frac{3}{2}$

$log_{2\sqrt 2} X = k * \frac{1}{2} *\frac{2}{3}$

$log_{2\sqrt 2} X = k * \frac{1}{1} *\frac{1}{3}$

$log_{2\sqrt 2} X = \frac{1}{3}k$

WILL GIVE BRAINLIEST ANSWER.

steposvetlana [31]

1) In his old car:
number of gallons per year = 16000/20 = 800 gallos
cost of fuel per year = 800 x $3.2 = $2560

2) In his new car, the mileage of 16000 remains the same and the cost per gallon $3.2 also.
I he made a saving of $ 675, that means only the mileage per gallon changed from 20 mi/gal to x mi/gal. (x certainly is greater than 20).
So we have to calculate the new mileage.
Let x be the NEW mileage/gallon:
a) Number of gallon per year = 16000/x
b) Cost of few per year = (16000/x).(3.2) = (2560 - 675)

= (48000/x)= 1825
(cross multiplication) → x = 48000/1825 and x = 26.3 mi/gal (NEW mi/gal)

Then, with his new car he gained 26.3 - 20 = 6.3 mi/gal (more tan with his old car)
