Amath teacher gave her class two tests. 70% of the class passed both tests and 80% of the class passed the first test. what percent of those who passed the first test also passed the second test?
70%
75.5%
87.5%
none of the choices are correct.

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
