Answer:
7,897.30 miles
Step-by-step explanation:
It is given that the North Pole is at a distance of 3,949 miles from the center of the earth.
We also know that the sea floor is below 2.4 miles from the sea level.
It is given that a submarine is located at the sea floor near North Pole. Hence, the distance of the submarine from the center of the earth would be
3949 - 2.4 = 3946.6 miles.
On the other hand, the South Pole is given to be at an elevation of 1.7 miles from the sea level.
Since we know that the sea level is at a distance of 3949 miles from the center of the earth, we can immediately calculate the distance of the South Pole from the center of the earth to be
3949 + 1.7 = 3950.7 miles.
Putting all of this together, we see that the center of the earth is at a distance of 3946.6 miles from the submarine near the North Pole, and the center of the earth in turn is 3950.7 miles from the South Pole.
Hence, the distance between the submarine and a person on the South Pole = 3946.6 + 3950.7 = 7897.3 miles.
Answer:
f(12)=12
Step-by-step explanation:
In the number 54, 625 from left to right:
5 represents 5,
2 represents 20
6 represents 600
4 represents 4000
5 represents 50,000
so
<span>
54,625=50,000+4,000+600+20+5=5*10,000+4*1000+6*100+2*10+5
another way we can write this number is </span>

Answer:
i) 5*10,000+4*1000+6*100+2*10+5
ii)

2 ways, which are essentially the same thing.
When Kaira wrote 96 +12 as 12(8+1), she "factorized" 12, that is Karira found that 12 is a factor of both 96 and 12.
then she wrote 95+15=5(19+3), that is she factorized 5,
5 is a factor of both 95 and 15 because 95=5* 19 and 15=5*3
To use this method to calculate 38+11 we need 38 and 11 to have some common factor (different from 1),
but 11 is a prime number, that is, it has no factors except 1 and 11. We can only apply the method if 11 is a factor of 38, but it is not.
Answer: The method is called "factorization", and it cannot be applied to calculate 38+11
