Step-by-step explanation:
S.A = 465
4πr²= 465
r². = 36.9
r. = 6.08
volume of a sphere = 4/3πr³
= 4/3π * 6.08³
= 941.8 cm³
2x + y = 17
To solve for y, subtract 2x from both sides;
y = 17 - 2xTo solve for x, subtract y from both sides;
2x = 17 - y
Divide both sides by 2;

Answer:
The value of Z = 0.3066... Or 0.31.
Step-by-step explanation:
The formula of direct proportional is a=kb (where k is constant). Given that a=z=0.2 and b=x=15, equation is 0.2=15k,
k=0.2/15
k=0.0133333333333
If x is 23 then what is z?
z=0.0133333333333(23)
z=0.3066666 or 0.31
