Answer:
Option D
Step-by-step explanation:
![F=\frac{9}{5}C+32\\\\F-32=\frac{9}{5}C \\\\5(F-32)=9C\\\\\frac{5(F-32)}{9}=C \\\\C=\frac{5}{9}( {F-32})](https://tex.z-dn.net/?f=F%3D%5Cfrac%7B9%7D%7B5%7DC%2B32%5C%5C%5C%5CF-32%3D%5Cfrac%7B9%7D%7B5%7DC%20%20%5C%5C%5C%5C5%28F-32%29%3D9C%5C%5C%5C%5C%5Cfrac%7B5%28F-32%29%7D%7B9%7D%3DC%20%20%5C%5C%5C%5CC%3D%5Cfrac%7B5%7D%7B9%7D%28%20%7BF-32%7D%29)
For F=77°F
![C=\frac{5}{9}(F-32) \\\\C=\frac{5}{9}(77-32)\\\\C=\frac{5}{9}(45)\\\\C=\frac{225}{9} \\\\C=25](https://tex.z-dn.net/?f=C%3D%5Cfrac%7B5%7D%7B9%7D%28F-32%29%20%5C%5C%5C%5CC%3D%5Cfrac%7B5%7D%7B9%7D%2877-32%29%5C%5C%5C%5CC%3D%5Cfrac%7B5%7D%7B9%7D%2845%29%5C%5C%5C%5CC%3D%5Cfrac%7B225%7D%7B9%7D%20%5C%5C%5C%5CC%3D25)
False because if it’s a positive number then the opposite is gonna be a negative
We are given with two distances: 5,880,000,000,000 miles and 15.8 light-years. we convert first the light-years distance through the speed of light : 3 x 108 m/s. v = d/t; d = 3x10 8 m/s * 15.8 light years * 31536000 s = 1.4948 x1017 m = 9.28829 x 1013 miles. The difference thus is 8.70029 x 1013 miles
