V≈4188.79
Step-by-step explanation:
The formula of the volume of a sphere is V=4/3πr^3
15. 21
16. 38
17. 3072
18. 1
19. 44 (not 100% sure)
20. 11/13
21. 11/12
22. 36
Yes I think it is correct
If I=P*r*t, we can input 450 in for I, 3000 in for the principal (P, or the starting rate), and 3 for t=time because there were three years, resulting in 450=9000*r. Next, we can divide both sides by 9000 to get 0.05 or 5% as our answer.
Answer:
x=10
Step-by-step explanation:
Rearrange to get p on one side
2.5=0.4p-0.15p
2.5=0.25p
Divide both sides by 0.25
2.5/0.25=x
x=10
