Maya got more than Sam with $630

Step-by-step explanation:

Sam, Aria and Maya in a ratio of 4:9:11

4+9+11 = 24

Sam will get 4/24 x 2160 = 360

Maya will get 11/24 x 2160 =990

Maya got more than Sam with 990-360 = $630

Maya made $630 more than Sam.

Step-by-step explanation:

The total amount that Sam, Aria and Maya got paid for painting the house is $2160.

Since they worked for different number of hours on the job, the money was split in the ratio of

4 : 9 : 11

The total ratio is the sum of the proportions. It becomes

4 + 9 + 11 = 24

Therefore, the amount that Sam made was

4/24 × 2160 = $360

The amount that Aria made was

9/24 × 2160 = $810

The amount that Maya made was

11/24 × 2160 = $990

The difference in the amounts made by Maya and Sam is

990 - 360 = $630

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
