The jar has a total of 220 marbles the table shows the estimates of three different students and the amount of error in each of the estimates the class wants to know who has the best estimate of the percent error in Lacey's estimate 66 out of 20 equals blank percent error

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

choice b is correct

step-by-step explanation:

we have been given the following system of inequalities;

we are required to graph the solution to the system of inequalities. using a graphing tool, the graph of the system is as shown in the attachment. the continuous line represents the graph of while the dotted line represents .

i’ll just s take the points thxs

210/22 = 9.55

since he can't take part of a person to the game the answer is 9 people

hope this !
