Rachel’s free-throw average for basketball is 60%. Describe how you can use 10 index cards to model this situation. Then use a s
Thepotemich [5.8K]

1. If Rachel's free-throw percentage is 60%, you can take 4 index cards away since 100 - 40 = 60%. For example, if those 10 index cards represent 10 free-throws, and her percentage is 60%, just take 60 away from the total (100%).

2. For the simulation, it's the same as problem 1. Since 50 is the total amount of shots she is going to take, and you know she is going make 60% of them, take 60% from 50 which gives you 30. That means she will make 30 of them and miss 20 of them

The middle school is 2.72 Kilometers from Kim's house and 1.54 kilometers from Terri's house. How much farther in meter does Kim
TiliK225 [7]

Answer: 1,180  meters.

Step-by-step explanation:

Hi, to answer this question we have to subtract Terri's distance from the school (1.54) to Kim's distance from the school (2.72)

Mathematically speaking:

2.72 km - 1.54km = 1.18 km

Since the answer must be expressed in meters.

1000 meters = 1 kilometer

1.18 km x 1000 m/km = 1,180 meters.

Feel free to ask for more if needed or if you did not understand something.
