Ah clever. So you need two formulas.
1) Volume of the marble.
4(pi)r^3/3
= 4(pi)(1.4)^3/3
<span>= 11.49 (approx)
</span>
2) Formula for density.
D = M / V
= 9 / 11.49
= 0.78
0.78 < 1
Therefore the marble will float.
Answer:
Yes its correct
Step-by-step explanation:
Answer:
He buys 8 desks and 6 chairs can i have branliest
Step-by-step explanation:
Set up a system of equations
desks = y chairs = x
x+y=14
125x + 515y = 4870
Eliminate,
-125x -125y = -1750
125x + 515 y = 4870
390 y = 3120
y = 8
substitute in 8
x + 8 = 14
x = 6
Answer:216.818 miles per hour
Step-by-step explanation:
To convert from feets per second to miles per hour, you multiply by 15/22.
318 x 15/22
(318x15)/22
4770/22=216.818
Answer:
