Answer:
Step-by-step explanation:
126 buttons.....8 two holes for every 4 holes...added = 12
so 8/12 of the total buttons are two hole and 4/12 of the total buttons are four hole
8/12 of 126 = 2/3 * 126 = 252/3 = 84 two hole buttons <==
4/12 of 126 = 1/3 * 126 = 126/3 = 42 four hole buttons <==
better have my money
3/10
5 11/12
2 4/16 = 2 1/4
2 1/4 + 3 2/3 = 9/4 + 11/3
27/12 + 44/12 = 71/12 = 5 11/12
A.) 1764π ft3.
Volume = π r^2 h
= 14^2 * 9 * π
= 196*9 * π
= 1764 π ft3.
