On monday 336 fourth graders went on a field trip to a local park. the teachers divided them into 8 groups. use a basic fact. estimate the number of students in each group.

42 students

Step-by-step explanation:

If 336 fourth graders went on a field trip to a local park and they are divided into 8groups, the estimate number of students in each group will be gotten using the formula;

Number of student in each group= total number of students/total number of groups

Number of students in each group = 336/8 = 42

This means that there are 42students in each group.

part a: triangles gcb and epb

part b. sides cg and rp are parallel by definition of parallelogram.

angles cgb and e are congruent by being alternate interior angles of parallel lines cut by a transversal. angles gbc and ebp are congruent because they are vertical angles. by aa similarity, the triangles are similar.

part c. since the triangles are similar, the ratios of the lengths of corresponding sides are equal.

calculation of be:

gb/be = cb/bp

(400 ft)/be = 300/200

(400 ft)/be = 3/2

3be = 2 * 400 ft

3be = 800 ft

be = 800/3 ft

calculation of pe:

gc/pe = cb/bp

(350 ft)/pe = 300/200

(350 ft)/pe = 3/2

3pe = 2 * 350 ft

3pe = 700 ft

pe = 700/3 ft
