Serenity has a toy car collection. She keeps some in a display case and the rest on the wall.
104
of her toy cars are on the wall, and 74% of her toy cars are in the display
case. What is the total number of toy cars in Serenity's collection?

If 74% are in the display, then 100% - 74% = 26% are hung on the wall.

This means 104 cars is 26% of her collection.

To find the total collection divide the number on the wall by the percentage of the collection:

104/0.26 = 400

The total number of her collection is 400 cars.

y-1700=200(x+4)

200(x+4) is 200x + 800 she is saving 200 per week x is the weeks and the -1700 is. us that’s howmuch she already had

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
