Answer:
124250cm, 1242.5m or 1.2425km
Step-by-step explanation:
0.6% = 6/100
6/100 = 0.006
0.006*1.25 = 0.0075
1.25km = 1250m = 125000cm
0.0075km = 7.5m = 750cm
125000 - 750 = 124250
Therefore:
The answer is 124250cm, 1242.5m or 1.2425km

D is the right one, in all these suggestions , the number cube is rolled 1 time.
This is Pythagorean's Theorem, with one leg being 10 and the hypotenuse being 16. Using those values in the theorem looks like this:
![10^{2} + b^{2} = 16^{2}](https://tex.z-dn.net/?f=%2010%5E%7B2%7D%20%2B%20b%5E%7B2%7D%20%3D%2016%5E%7B2%7D%20)
and
![100+ b^{2} =256](https://tex.z-dn.net/?f=100%2B%20b%5E%7B2%7D%20%3D256)
and
![b^{2} =256-100](https://tex.z-dn.net/?f=%20b%5E%7B2%7D%20%3D256-100)
so
![b^{2} =156](https://tex.z-dn.net/?f=%20b%5E%7B2%7D%20%3D156)
Take the square root of both sides to find that b = 12.5
6x + 7(1-x) = -4(x-4)
6x + 7 - 7x = -4x + 16
-x + 7 = -4x + 16
-x + 4x = 16 - 7
3x = 9
x =9/3
x = 3
