In theory, they can remain unchanged for their entire existence. However, in practise, nature isn't so nice and evolution happens eventually.
It is made out of sand which is silicone dioxide also called quartz.
3 2 is 100 thousands 3 is 10 thousands 4 is thousands 5 is hundreds 6 is tens 7 is units
around thousands of them or look in Wikipedia and I only found around 196 just said hundreds of them.
Fossil Fuel Power Plants were created when.....
There are hundreds, perhaps even thousands of chemicals which contain calcium. A few of these are Calcium chloride, calcium suplhate, calcium hydroxide and calcium carbonate.
None of the "following".
Thousands
The most durableman-made creaton ever is Buzz Aldrin's foot print on the moon.=It's expected to remain unchanged for hundreds of thousands of years.=
It is simply an unspecified number of hundreds of thousands!
hundreds
Sixty hundreds can be converted to thousands by dividing by 10, since 1 thousand equals 10 hundreds. Therefore, 60 hundreds is equal to 6 thousands.
How many thousands equal 50 hundreds?
To convert hundreds of thousands to millions, you divide by 10. Since 60 hundreds of thousands is equivalent to 60 x 100,000, that equals 6,000,000. Therefore, 60 hundreds of thousands is 6 million.
7 hundreds thousands
Obviously not!!
To find out how many hundred thousands are in 7,000 hundreds, first convert hundreds to thousands. Since 1 hundred is 0.1 thousand, 7,000 hundreds is equal to 700 thousands. There are 10 hundred thousands in 700 thousands, so the answer is 10.
There is no four digit number where the ones is twice the tens, the hundreds is five less than the ones, and the thousands is the sum of the tens and hundreds. int ones, tens, hundreds, thousands; for (thousands=1; thousands<10; thousands++) { /**/ for (hundreds=0; hundreds<10; hundreds++) { /**/ /**/ for (tens=0; tens<10; tens++) { /**/ /**/ /**/ for (ones=0; ones<10; ones++) { /**/ /**/ /**/ /**/ if (ones != 2 * tens) break; /**/ /**/ /**/ /**/ if (hundreds != ones - 5) break; /**/ /**/ /**/ /**/ if (thousands != tens + hundreds) break; /**/ /**/ /**/ /**/ printf ("dd\n", thousands, hundreds, tens, ones); /**/ /**/ /**/ } /**/ /**/ } /**/ } }
