The ratio of red to blue marbles is 4 to 5. If there are 36 marbles
how many are blue?

There are 45 blue marbles

Step-by-step explanation:

Well if 4 times 9 is 36, then 5 times 9 is 45

= 36 : 45

rounding to the nearest thousandth would be 452,000

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.
