Answer: Carla P. 15.1
Step-by-step explanation:
20 students.
40% are boys. (40/100)*20 = 0.4 * 20 = 8 boys.
Girls= 20 - 8 = 12 girls.
25% of the boys wear glasses. = (25/100)*8 = 0.25*8 = 2 boys wear glasses.
50% of the girls wear glasses. = (50/100)*12 = 0.50*12 = 6 girls wear glasses.
Total students that wear glasses = 2 + 6 = 8 students.
8 students wear glasses.
Assuming you can’t use the same topping twice,
10 x 9 x 8 = 720
The square root of 7 is an irrational number.
If you do 81 x 9 which equals 729. If you want to check, you do 729 divided by 9 and you get 81.
