Answer:
Canada has the highest and lowest is Kiribati the difference is 1,809,999,999,833
Explanation:
Answer:
The correct answer is - 20.
Explanation:
According to the triangle inequality theorem states that the largest and smallest value of the third side of the triangle can be found with the other two sides. The lowest value would be more than the difference of the other two sides and the largest value would be less than the sum of the other two sides of the triangle.
In this case, the other two sides are - 9 and 12
suppose the third side is - x
Then according to the triangle inequality theorem, the largest value of x would be:
x< 12+9
x< 21
so the x would be less than the 21 which is - 20.
Answer:
C). Corundum
Explanation:
Corundum is a crystalline type of aluminum oxide that usually contains iron, titanium, vanadium and chromium traces. Corundum is an incredibly durable and hard material. It is the third hardest mineral, after moissanite and diamond.
A geologist determine that a sample of a mineral can’t be scratched by a steel naill but can be scratched by a Masonary drill bit. Based on this information, the sample mineral has to be softer than CORUNDUM.
Due to Corundum's hardness , it can scratch almost every other mineral, and Since corundum is harder than the drill bit of masonry that can smash the mineral sample and thus the mineral sample must be softer than corundum.
