Which model are 60% of the square shades

6 shaded squares and 4 unshadedshaded = 60%

Step-by-step explanation:

a grid with 100 squares, 6 are shaded6/100 = 0.06 = 6%

a grid with 100 squares, 36 are shaded36/100 = 0.36 = 36%

6 shaded squares and 4 unshaded...6:4...added = 10

shaded = 6/10 = 0.6 = 60% <

4 shaded squares and 6 unshaded...4:6...added = 10

shaded = 4/10 = 0.4 = 40%

the answer is 510

step-by-step explanation:

15 • 13 = 195

15 • 12 = 180

15 • 5 = 75

12 • 5 = 60

195 + 180 = 375

375 + 75 = 450

450 + 60 = 510

a - base

b - exponent
