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. Y

TiliK225 [7]

Answer:

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.

Answer:

D) 50ft

Step-by-step explanation:

(18×x) + (32×18) + [(48-18-18)×(32-11)]

= 1728

18x + 576 + (12×21) = 1728

18x = 1728 - 828

18x = 900

x = 50
