20 points A store sells beans for 80 cent per pound.

A. Graph The proportional relationship that gives the cost y in dollars of buying x pounds of beans.

B. Write an equation of the form Y=kx to represent this relationship

i leave the calculator work to you.

7. diameter 4 miles, circumference 4π miles

8. radius 0.2 miles, circumference 0.4π miles

[this is a bad problem because the actual radius of a car on the track is less than 0.2 miles so the answer is less than 0.4π miles]

9. radius 6 feet, circumference 12π feet

10. diameter 14 cm, circumference 14π cm

11. diameter 4.8 feet, circumference 4.8π feet

my guess would be b and d, but i didn’t actually get out the pen and paper. lol

d 600 because 15*10*2=300

300+300=600

step-by-step explanation:

the answer should be a. snail
