NEED HELP PLS I AM GOING TO CRY

Step-by-step explanation:

Daniel 60

Isabella 30=60/2=2=50%

Mia 90

Step-by-step explanation:

To find the percentage of a number use this formula: %/100 × x/1

Let me help you understand this formula.

According to the word problem, Daniel finished his homework in 60 minutes. Isabella finished his work in 50% of Daniel's time (60). And, Mia finished her work in 150% of Daniel's time.

To find out how much time it took Isabella to finish her homework, we need to find the 50% of 60.

%/100 × x/1

50/100 x 60/1 = 3000/100 = 30

50% of 60 is 30; Isabella finished her homework in 30 minutes.

Mia finished her homework in..

%/100 × x/1

150/100 x 60/1 = 9000/100 = 90

90 is 150% of 60; Mia finished her homework in 90 minutes (1 hour and 30 minutes).

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
