Answer:
0.5
Step-by-step explanation:
Check the picture below.
make sure your calculator is in Degree mode.
First you need to divide 125 / 25 which is 5 then you do subtraction 21 x 5 which is 105, then you subtract again 125 - 105 which is 20, 20 light bulbs will be broken. Or you could have just multiplied 5 by 4 which is the amount of light bulbs that were broken which is a lot easier...
I would say 8.0 Because if you do 12.6-4.9 you get 7.7 ...hope that helped
