62.4g of sugar is needed to make 8 cakes. How much sugar is needed for 9 cakes?

70.2g

Step-by-step explanation:

62.4 g will make 8 cakes, so to find out how much sugar we need to make

1 cake will divide 62.4 into 8 equal parts.

62.4/8 = 7.8g of sugar is needed to make 1 cake

62.4+7.8 = 70.2g  will make 9 cakes

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

i would need to see the dot plot : )
