How can you use a 10-by-10 grid to model 12%? You can shade half of the squares. You can shade half of one row of the squares. You can shade half of one of the squares. You can shade 2 of the squares.

The options provided do not have the correct answer. Read below.

Step-by-step explanation:

Given a 10 by 10 grid model means that there are exactly 100 individual squares present. This shows that each square is equal to 1%.

None of the options provided gives us 12% of the model.

The first option results in 50%, the second results in 5%, third option results in 0.5% and the last option results in 2%.

For 12% we can shade 12 squares completely, half of 24 squares etc.

I hope this answer helps.

54 km / hours

step-by-step explanation:

we need to convert seconds to hours

60 seconds = 1 minutes

60 minutes = 1hour

15 m         60 second   60 minutes

  * *         = 54000 meters/ hour

second     1 minute             1 hour

now we need to convert meters to km

1000 m = 1 km

54000 m       1 km

*   = 54 km / hours

hour               1000m
