A cone has a radius of 5 inches and a height of 18 inches.
pychu [463]
It would be C., because to find the volume, you would have to multiply the radius by itself, to get the diameter. Then, the answer you get will have to be multiplied by the height.: 5 times 5 equals 25, and then 25 times 18 equals 450.

Show that log√7 + log√20 - log√14 = 1/2
Mademuasel [1]

Alright, lets get started.

log \sqrt{7}  + log \sqrt{20}  - log\sqrt{14} = \frac{1}{2}

We could write this square root as \frac{1}{2}

log7^{\frac{1}{2}} + log20^{\frac{1}{2}}- log14^{\frac{1}{2}}

Using the property of logm^{n } = n log (m)

\frac{1}{2}log 7 + \frac{1}{2} log 20 - \frac{1}{2} log14

\frac{1}{2} is common in each term, so

\frac{1}{2}(log7 + log 20 - log 14)

Using property of log m  + log n = log(mn)

\frac{1}{2}(log 140 - log 14)

Using property of log m - log n = log\frac{m}{n}

\frac{1}{2}log\frac{140}{14}

\frac{1}{2} log 10

log 10 value is 1 , hence

\frac{1}{2} * 1 = \frac{1}{2} : Answer

Hope it will help :)

By weight, oxygen makes up approximately 65% of the human body.  

Numerically, hydrogen approaches 65% of the total number of atoms in the human body, but it is probably closer to 63% for most people.  

Accounting by Mass:

The mass of the human body is provided mostly by oxygen, carbon, hydrogen, nitrogen. Together these elements account for about 96% of the mass of a human.
