Total time spent reading is = 8/9 hour
He spends 1/4 of the time reading world news. That is = 1/4 * 8/9 = 2/9 hour
Splits the remaining time equally. Remaining time = 8/9 - 2/9 = 6/9
Splitting it equally = 6/9 divided by 2 = 6/9 * 1/2 = 3/9 = 1/3
Time spent reading comic is = 1/3 hour
I hope this helps.
5 - substitute the numbers 1-10 for n in (3n-4) and add up all your answers. So (3(1)-4) + (3(2)-4)...
So, angles A and B added together is 130° which makes the whole angle = 180°-130°=50°
The answer is 180° because it is a supplementary angle and all supplementary angles equal 180° so, all the angles added makes 180°
