Answer:
Z = Ma = ba
You made a typo. One of those = signs should either
be a + and a -. Here are all possibilities:
1. Z+Ma = ba, solve for a
Ma-Ba = -Z
a(M-B) = -Z
a = -Z/(M-B)
2. Z = Ma+ba, solve for a
Ma+ba = Z
a(M+b) = Z
a = Z/(M+b)
3. Z-Ma = ba, solve for a
Z = Ma+ba
Ma+ba = Z
a(M+b) = Z
a = Z/(M+b)
4. Z = Ma-ba, solve for a
Ma-ba = Z
a(M-b) = Z
a = Z/(M-b)

Answer:
Sa = 1.5*V
Step-by-step explanation:
We have that the surface area of a sphere has the following formula:
Sa = 4*pi*r^2
we know that r = 2, so if we replace it, we're left:
Sa = 4*pi*(2^2)= = 4*pi*4
Sa = 16*pi
Now, the volume has the following formula:
V = 4/3*pi* r^3
Replacing it is our job:
V = 4/3*pi* (2^3) = 4/3*pi*8
V = 32/3*pi
Now, Sa/V, it would remain:
Sa/V = 16*pi / 32/3*pi
Sa/V = 48/32 = 1.5
Therefore, Sa = 1.5*V
