Idon’t need an explanation but someone

The prices of the 2 stocks will be the same at 13.6 hours

Step-by-step explanation:

Write 2 equations with the given information:

y = 0.07(x - 9) + 15.53

y = -0.11(x - 12) + 16.03

y is price and x is time

Find where they intersect:

0.07(x - 9) + 15.53 = -0.11(x - 12) + 16.03

0.07x - 0.63 + 15.53 = -0.11x + 1.32 + 16.03

0.07x + 14.9 = -0.11x + 16.35

0.18x = 2.45

x = 13.6

The prices of the 2 stocks will be the same at 13.6 hours

brainliest would be appreciated.

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6
