Use the formula V=AbH and 48=16h will be the second step and then divide by 16 and then you get the answer
1) (-7)3
2) PEMDAS; simplify (5-3)
3) 5^3, 5x5x5 and 125
4) -8^4
5) 36
6) 7
7) -100
8) 30
There ya go! Pretty sure they're all right!
70 because you would divide 150.8 by 2 and it gives you 75.4 but you have to round it and do v=4/3×3.14×70^3
Well 125 is 100 + 25. Put those into decimal form, separately, then add them together.
100 --> 1.0
25 --> 0.25
1.0 + 0.25 = 1.25
Change from decimal to fraction form:
1.25 --> 1&1/4
