## What is the percentage of change from 166 deaths in 2002 to 552 deaths in 2009?

How do I get the percentage of change?

Deaths in 2002=166
deaths in 2009=552
change=552-166=486
% change=486/166 x100= 292.77

## How do I do this scientific notation question?

The mass of the sun is 2.2 x 10 to the power of 30 kilograms.
The mass of the earth is 5.97 x 10 to the power of 24 kilograms.
Express the mass of the earth as a percentage of the mass of the sun.

You divide the mass of earth by the mass of the Sun, so (5.97×10^24) / (2.2×10^30)
It simplifies to (5.97/2.2)x(10^24)/(10^30)= 2.713x(1/10^6)= 2.71x(10^-6)=2.71×10-6. Now as they say it has to be in a percentage, we multiply by 100, so (2.71×10^-6)x100=2.71×10^-4

## Your Open Question: How do the new fujifilm X(100s/20) cameras compare to the full frame Nikon d600/Canon 6d?

I know they’re completely used for a different type of photography, but i just want to know about image quality. Im not concerned about auto focus one bit… If the image quality is the same i just want to go with what’s lighter

Since the Fujifilm camera has yet to be tested, all I can do is show you the results of the Nikon D600 and Canon 6D

## what are the main Controls and features of a compact camera?

what are the main Controls and features of a compact camera?

Basic compact (e.g. Nikon Coolpix L-series, Canon Powershot A-series) – Shutter button, zoom controls. Reviewing options, force macro focus, select scene program, timer.

Fashion/premium compact (e.g. Canon IXUS, Fujifilm Finepix Z-series, Sony Cybershot T-series) – Same as basic compact plus, program AE, and more “creative” options.

Travel zoom compact (e.g. Panasonic Lumix TZ-series, Canon Powershot SX2xx series) – Same as basic compact plus, more zoom range, Program AE, Aperture Priority, Shutter Priority, Manual exposure, and zone focus control.

Prosumer compact (e.g. Canon Powershot S-series, G-series, Panasonic Lumix LX-series, Fujifilm X-10, Nikon Coolpix P-series) – Same as travel zoom, plus SLR-like layout (some models), optical viewfinder (some models), hot shoe (some models), electronic viewfinder attachment (Panasonic and Olympus only), and manual focus.

Bridge (e.g. Finepix X-S, Finepix S, Powershot SX10-50, Lumix FZ-series) – Same as travel zoom plus, manual focus (high end models only), electronic viewfinder, a lot more zoom range. Looks a bit like an SLR with it’s hump.

Specialist compact (i.e. Sigma DP1/2 series, Leica X1, X2, Fujifilm Finepix X100, Canon Powershot G1X) – everything you’d expect on a DSLR, except the lens on these cameras cannot be removed.

## How to turn a number into a percent?

Could you please explain how 0.1 = 10% ?
Obviously, you get it by multiplying 0.1 by 100. But, lets say that I have a number that is equal to 50. To turn it into percentage, do I divide it by 100?
What is the difference between the two?
Ok. Please, explain to me how to convert 0.1 into percents.
