Answer:Walnuts cost $1.25 and chocolate chips cost $3.25
Step-by-step explanation: Make walnuts x and chocolate chips y.
3x+5y=20
6x+2y=14
Multiply the first equation by 2 and then subtract it from the second.
-(6x+10y=40)
6x+2y=14
-8y=-26
y=3.25
Plug y back into either equation and isolate x to solve for x.
6x+2(3.25)=14
6x+6.5=14
6x=7.5
x=1.25
Sphere Surface Area = <span> 4 • <span>π <span>• r²
For it to equal 16 PI, then radius must equal 2
4*PI*2*2 = 16 PI
</span></span></span>
Sphere Volume = <span> 4/3 • <span>π <span>• r³
</span></span></span>
Sphere Volume = <span> 4/3 • <span>π <span>• 2^3
</span></span></span>
Sphere Volume = <span> 4/3 *PI * 8
</span>
Sphere Volume = <span> 32 / 3 PI
</span>
Sphere Volume = <span> 10.666 PI cubic feet AND I think that is answer B
which SHOULD read 10 (2/3) PI ft^3
</span>
Answer:
b (1/15)
