At a charity bike rally, 2/3 of the student population of Heartsworth Middle School participated. If there are 1,200 students at Heartsworth, how many participated? Write in simplest form

800 students

Step-by-step explanation:

1200/3=400

400×2=800

is there answer choices?

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.
