Answer:
it would be 4
Step-by-step explanation:
We know that
[volume of the composite figure]=volume of cylinder + volume hemisphere
volume cylinder=pi*r²*h
r=4 mm
h=7 mm
volume cylinder=pi*4²*7----> 351.68 mm³
volume of hemisphere=(4/6)*pi*r³
r=4 mm
volume of hemisphere=(4/6)*pi*4³----> 133.97 mm³
[volume of the composite figure]=351.68+133.97----> 485.65 mm³
If it needs to be in decimal form it would be: y=0.25x-6
Fraction form would be: y=1/4x-6
Answer:
I believe its B
Step-by-step explanation
> is pointing away from -4 there for its going away from -4
Step-by-step explanation:
$4 per week from washing car
