Write it as in ascending order:
a)1:2, 3:5,3:10,3:2,4:5

1) 3 : 10 (0.3)

2) 1 : 2 (0.5)

3) 3 : 5 (0.6)

4) 4 : 5 (0.8)

5) 3 : 2 (1.5)

Step-by-step explanation:

1 : 2 = 0.5

3 : 5 = 0.6

3 : 10 = 0.3

3 : 2 = 1.5

4 : 5 = 0.8

so

1) 3 : 10 (0.3)

2) 1 : 2 (0.5)

3) 3 : 5 (0.6)

4) 4 : 5 (0.8)

5) 3 : 2 (1.5)

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

part a

in a city ice cream is mostly only bought when the temperature is very high as ice cream cools down our

so we can derive the conclusion that as the temperature increases the number of ice creams sold also increases

part b

y intercept is 5

slope is 2
