V=(4/3)r^3
first one
V=(4/3)(1/2)^3
V=4/24
V=1/6
V=(4/3)(3/4)^3
V=108/192
V=9/16
compare
1/6 to 9/16
16/96 compared to 54/96
well, the bigger ballon is 19/8 ft^3 bigger than smaller oe
Answer:
Money Ivan gets extra = 120 - 30 (or 3x) = 90
Step-by-step explanation:
Ivan = 4x
Tanya = 1x
Total = 150
4x + x = 150
5x = 150 ; x = 150 / 5 = 30
Ivan = 4x = 120
Tanya = 1x = 30
Money Ivan gets extra = 120 - 30 (or 3x) = 90
im pretty sure it's the first option.
