What is Logarithm?

In mathematics, Logarithms are defined a way of expressing exponents. A logarithm is defined as the power to which a number must be raised to get some other values.

The expression for logarithm of a number is written as ㏒ₓb = y.

Properties of Logarithm:

$log_(x) (x^n) = n$

The value of $log_(2)(1)/(8)$ can be calculated by recognizing that $(1)/(8)$ is equal to 2 raised to the power of -3.

$log_(2)(1)/(8)$ = $log_(2)(2^(-3))$

From the property of logarithm:

$log_(2)(2^(-3))$

= -3

The value of $log_(2)(1)/(8)$ is -3.

The ratio of side lengths is approximately 1.4.
We need to first figure out which sides correspond to which.

13/9.29 = 1.39935 which is close to 1.4, so the sides 13 cm and 9.29 cm are corresponding sides.

8/5.71 = 1.401 which is close to 1.4, so the sides 8 cm and 5.71 cm are corresponding sides.

That leaves the 7 cm side corresponding to the unknown side.

7 cm/1.4 = 5 cm

Answer: D. 5 cm

4 hours and 25 minutes before 2:05am

Answers

4 hours and 25 minutes before 2:95 am would be 9:40pm

Answer:10:20 pm

Step-by-step explanation:

Time is seperated into 2 sets of 12 hours, am and pm; and 24 hours with each being 60 minutes. AM is morning and PM is afternoon.

The question is what time is 4 hours and 25 minutes before 2:05 in the afternoon. This means you subtract.

205 - 425= -220

Then, because it is negative, you change it from am to pm and subtract 220 from 1200=

1200-220=980

9:80 is has too high a number in the minutes section (the second part) so you see how many sets of 60 are in 80. There is one set of 60 meaning there is one hour added to the hour side (the left side):

9+1: 80-60

10:20

10:20 pm is the final answer.

Hope this helped;)
