Answer:53
Step-by-step explanation:
B>a
b=8a-1
and we are told that 98=a+b so a=98-b, using this value for a in the equation above gives you:
b=8(98-b)-1
b=784-8b-1
b=783-8b
9b=783
b=87, and since a+b=98, a=11
so a and b are 11 and 87
Density = mass/volume
the mass is 10578.9 pounds
the volume of a sphere is v = 4/3 πr^3
v = (4/3) (π) (4.3)^3
v = 333.04
10578.9 / 333.04 = 31.76
the final density is 31.76!!
