James and Ahmik went to a bicycle show. Of the bicycles they saw at the show, 32% were blue, 25% were red, 25% were green, and 18% were black. In ratio form, what percent of the bicycles were red or black?

43:100

Step-by-step explanation:

Percentage of bicycles that are blue = 32%

Percentage of bicycles that are red = 25%

Percentage of bicycles that are green = 25%

Percentage of bicycles that are black = 18%

Percentage of bicycles that are red or black = 25% + 18% = 43%

Therefore, 43% will be written in ratio form as 43:100

answer: option a.

step-by-step explanation:

you know that the quadrilateral opqr ( a four sided figure) is inscribed in circle. this means that all its vertices are on the circle.

then, by definition, the opposite angles of the quadrilateral are supplementary, this means that the sum of their measures is 180 degrees.

you can observe in the figure that the angles ∠opq   and the angle ∠orq   are opposite, therefore:

then, can be used to d to calculate the measure of ∠opq
