It costs $4 to enter the fair. each ride costs $2.50. you have $21.50, how many rides can you go on?

21.50-4=17.50

17.50÷2.50=7

so you can go on 7 rides

Step-by-step explanation:

answer rather than having to add and subtract the measurements of the semi-circle, notice that the semicircle to the left of ad is actually identical in area to the blank semicircle-shaped space to the left of bc. so if we transferred the red semicircle into the blank space, we would end up with a square of side length 24 cm. the area of a square is s^2 = 24^2 = 676 cm^2.
