Step-by-step explanation:
First you will divide 525 by 100. Then you multiply your answer by 4. That will equal 21
The impact of a very large volcanic eruption that have an effect on earth's climate is <u>It will cool the earth's surface as radiation from the sun is blocked from entering the atmosphere.</u>
<u />
Explanation:
A very large volcanic eruption will spew tonnes of fine dust particles (pyroclast) into the atmosphere. These particles will be spread over large area by wind and the particles will remain suspended in the air for longer periods before they settle on the earth's surface.
The suspended particles will block the sun, and by reflecting most of the sunlight before it reaches the earth’s surface, will cause the surface temperatures to drop.
This same phenomenon caused the demise of dinosaurs after a meteorite strike threw dust particles into the atmosphere that lingered for a long time smothering plant life too.
Answer:
a=4
c=5
e=7
f=1
Step-by-step explanation:
the simplest method would be to start with a(2)"squared" (being '4' as this will get you closest to 15. So 16 -1 (being 'c') = 15. now plug those into the other equations and work the other numbers out.
Answer:
27
Step-by-step explanation:
Evaluate the ![\sqrt[4]{81}](https://tex.z-dn.net/?f=%5Csqrt%5B4%5D%7B81%7D)
= 3
Since 
= 81
We are noe left to evaluate (3)³ = 27
