There is 5/6 of an apple pie left from dinner. Tomorrow, victor plans to eat 1/6 of the pie that was left. How much of the whole pie will be left after he eats tomorrow?

Answers

lets assume the whole pie is 1, that is all fractions added together have to sum 1.
If Victor eats 1/6 out of 5/6, then the rest is 4/6 of the pie, that is the subtraction of those fractions.

then round to 6.84

Is 324 inches least, greater, or equal to 27ft

Answers

1 foot = 12 inches
2 feet = (2 x 12 inches) = 24 inches
3 feet = (3 x 12 inches) = 36 inches
.
5 feet = (5 x 12 inches) = 60 inches
.
.
10 feet = (10 x 12 inches) = 120 inches
.
.
20 feet = (20 x 12 inches) = 240 inches
.
.
27 feet = (27 x 12 inches) = 324 inches I guess they're equal !

Yes.

324/12=27

Hope this helps :)

Solve log base 2 of one eighth

Answers

Answer:

-3

Step-by-step explanation:

$log_(2)$ (1/8)

= $log_(2)$ 1 - $log_(2)$ 8 ( recall $log_(2)$ 1 = 0)

= 0 - $log_(2)$ 8

= - $log_(2)$ 8 (change base to base 10)

= - (log 8) / (log 2) (now you can use a calculator)

= - 3

The log base 2 of $(1)/(8)$ , i.e., $\log_2 (1)/(8)$ is -3.

In mathematics, the logarithm, denoted as "log," is an important mathematical function that represents the exponent to which a fixed base must be raised to obtain a given number. It is the inverse operation of exponentiation.

The logarithm function is typically written as $log_b(x)$ , where x is the number for which we want to find the logarithm and b is the base. The base can be any positive number greater than 1, commonly used bases include 10 (logarithm to the base 10, often written as log(x)) and the mathematical constant e (natural logarithm, often written as ln(x)).
