Final answer:
Tannis' second machine can throw a car 189 meters, as you calculate this by multiplying the first machine's throw distance (27 meters) by 7.
Step-by-step explanation:
The student asked how far Tannis' second machine could throw a car if the first machine threw a car 27 meters and the second machine could throw 7 times as far. To find the distance the second machine can throw a car, you multiply the distance the first machine can throw by 7. So, the calculation is 27 meters × 7 which equals 189 meters. Therefore, the correct choice is (Choice A). The second machine can throw a car 189 meters.
