Suppose that $60\%$ of the eighth graders and $30\%$ of the seventh graders at Washington Junior High participate in MATHCOUNTS. There are $150\%$ as many eighth-graders as there are seventh graders at the school. What percentage of the seventh and eighth graders, taken together, participates in MATHCOUNTS?

step-by-step explanation:

idk the answer i want to say 10 but then it would be equal so try 9 but then yeah so yeah we love edgen

c. 27 units.

step-by-step explanation:

we are told that in circle a, ∠bae ≅ ∠dae.

we can see from our given diagram that in and ;

, as these are radii of our given circle.

therefore, by sas congruence postulate.

hence, side be will be equal to side de as corresponding parts of congruent triangles are congruent. so we can set an equation to find the value of x as:

now let us substitute x=17 in the expression for the length of be.

therefore, length of be will be 27 units and option c is the correct choice.
