<h3>Answer:</h3>
- 28/100 = 7/25
- 100/28 = 25/7
<h3>Explanation:</h3>
The wording "the ratio of A to B" means A/B.
Here, "the ratio of the weight of silicon to the weight of crust" means ...
... (28 tons)/(100 tons)
Canceling common factors (and common units), this is ...
... 28/100 = 7/25
___
Then "the ratio of the weight of crust to the weight of silicon" means ...
... (100 tons)/(28 tons) = 100/28 = 25/7
well you could make 1 triangle that is 6 by 6 by 4
but if you mean as much as possible it would be 4 triangles because you could use 1 cm for each triangle but since there is only 4cm on one of the side which I'm guessing is the bottom part because that is ushally the smallest but you would run out of cm for the 4 bottom part on the 4th triangle so in conclusion 4

8*8 = 64 which is the first option
<u><em>Explanation:</em></u>
8 times as many as 8 means that we will repeat the number 8 for 8 times. This means that:
8 times as many as 8 = 8 + 8 + 8 + 8 + 8 + 8 + 8 + 8 = 8 * 8
This quantity is equivalent to 64.
Therefore:
8*8 = 64

I believe SI is the international system of measurements, our metric system. You would want to use this when numbers begin to get too small, or too large. Some examples would be when calculating distances of spacial bodies such as the distance from earth to the center of the milky way which is about <span>1,000,000,000,000,000,000 km or 1*10^18. 1*10^18 is easier to write and is less confusing.</span>
